  • From the above features of the non-compliance report of the last audit, it is seen that a total of  03 NCRs were identified in the different Departments.
  • Almost all the NCRs were identified due to the lacking public focussing, Preservation of emergency telephone numbers, etc.
  • A systematic follow up audit was conducted to against corrective and the preventive actions that were taken by respective departments.
  • Out of the total NCRs 03 were closed within the estimated time frame and 03 closed after exceeding the time frame.

Actions:

  • According to the suggestion of the Managing Director, the CFT member will be more sincere and regular on their activity. 

Internal Audit Result :

  • Third Internal audit was held on September 27th, 2004 and conducted by the consultant and qualified auditors from the Auto  internal auditors panel according to the schedule.
  • All elements of the ISO 14001 standard for the EMS have been covered during the audit.
  • The total features of the audit are given below to show the current status of the audit results:

Status of ETP

  • Total water preserving capacity was three Lac litters
  • At previous plants wastewater equalized by underground mixer motor
  • At previous plants submersible pump capacity and quantity was not sufficient.
  • The place where the operator stand for operating the lime dosing system was not sufficient.
  • At previous plants acetic acid was mixed with waste water at step # 01
  • Its capacity raise on twelve lack liters
  • Now its developing by compressed air-mixing system.
  • Now we purchase more capable of exerting great physical force submersible pump and other relative materials.
  • Now we make a completely different modification in lime dosing system where have an automatic lime mixing system, In addition it will uplift limewater in the lime mixer tank.
  • According to new diagram it will be mixed at step # 02

Environmental Program (Objectives & Targets)

In the meting, progress about environmental program including objectives and targets has been discussed.

Requirements have been submitted as per E.T.P step-1, and step-2. Because of some communication problems and settle of rainwater, we could not continue our activities smoothly.

Several training programs have been arranged for proper disposal of solid waste. First, EMR trained the CFT members and department heads.  Then the Departmental heads trained their employees respectively. After providing training on the basis of Training Needs Matrix and Training plan, we recorded all the training provided. Then we conducted an evaluation report for the provided training. We are now on the way of arranging refresher training. It was excepted that we shall be able to achieve the target within the scheduled time.

Action: At that situation, EMR has called an immediate CFT meeting. As per the dissection of CFT members, Maintenance department has taken the rapid action.

The pump was damage and immediate one new pump replace their. In that time with help of construction department close that way where from waste water go throw to the neighbours land and fishery project. In this way, wastewater leakage has been solved and it was reported to the neighbour.

Then they ware satisfied and given no objection letter.  

Conclusion

Minimising failure rates

The aim of this option is to increase product quality by minimising failure rates.Your products are the figureheads of your company, having a significant impact on your company’s reputation. Minimising failure rates supports your efforts to deliver products of prime quality and should thus be seen as a key strategy for your business success. While most failures occur during the processing, their cause might be found in-house as well as beyond your company’s gates, at your suppliers’ or shipper’s side. Inferior raw material and chemical quality, inadequate handling or unprotected transportation of products are just a few examples.

For an overview of your most frequent failure rates, fill out the table below. Describe to the best of your knowledge the failure, the process and exact location (e.g., which (part of the) machine/process), as well as the cause (see further guidance below the table) and the number of failures. If available, use data from the last fiscal year or the last quarter and state the chosen time-period in the table. Otherwise collect the necessary information. Also try to fill out the total number of failures that occurred during the time-period, which should not simply add up to rows above, but summarise all the failures.

Total number of failures:

For comparability reasons, make sure to use the same time-period (e.g., one fiscal year) for all failures. In case you do not have the information and/or cannot collect it, try to fill out table based on estimates. In this case, mention in the comments line that the figures are based on estimates. Using the generated data will help you to draw a trend line of your performance over different time-periods (benchmark), to identify improvement options and to set targets. With a benchmarking process you can compare your performance internally as well as externally, with industry averages or competitors. To benchmark your performance and see your improvements, use a “failure per unit” ratio. The “unit” should be the unit of production that is most useful for you. Examples could be “kg or m2 of product” or “1 000 units of product”.

Following the identification of failures you should determine their causes, as this allows you to remedy the defects. Next to technical problems with your processing technology, the following causes can be commonly found:
• Poor quality input material delivered from suppliers
• Non-existent quality control of the water supply bases on critical parameters (softness, iron content, colour, buffer capacity, conductivity, etc.)
• Sub-optimised material for your machinery
• Lack of proper training for the employees to locate and fix malfunctions
• Lack of processes and products monitoring (accuracy of the recipe, water solubility, pH, colour, conductivity)
• Absence of written instructions on how to operate the technology
Having identified the causes you should aim to remedy the defects.

As a complementary strategy, you might want to inform the employees involved in processing about the necessity of minimising failure rates. Providing information about the failures and malfunctions that occur is the first step to address these problems. Update your staff about your efforts to reduce the number of failures and publicise the results of your efforts to ensure an ongoing support.
Failure minimisation results in a more efficient production with lower energy, water, raw- and auxiliary material consumption, adequate chemical use and a reduction in the amount of wasted textiles that need to be disposed of.
Following an initial assessment, this option will require investments in both time and money. However, significant savings in materials, energy and water, as well as an increase of product quality can be achieved. Applying measures to improve product quality, the share of second quality or waste products can be reduced by 5% to 35%. Increasing your product quality will also satisfy your customers and open up new business opportunities.

Conclusion

The functions of the Effluent Treatment Plant Design committee in :

  • Fire safety conscious.
  • Housekeeping.
  • Maintaining records and minutes of committee meeting every 3 month.

Effluents Wastewater Disposal Process

Wastewater Disposal

Purpose & Scope: 

Wastewater Disposal – Waste Management No one can establish, provide or operate a waste disposal site without a permit issued by the Minister of Water Affairs and Forestry.This procedure details the system to be followed in order to ensure that all wastewater discharged by the Auto Garments Industry Limited are minimized and managed in an environmentally safe and correct manner in accordance with statutory and company requirements.The site discharges process water to the under ground tank and some of it over flows to drain.  Sludge Recycle of ETP

Wastewater Disposal Responsibilities:

No one may dispose of waste or discard it in any other way except at a licensed waste disposal site or at a facility or by a method subject to conditions as the Minister may prescribe.
Section 24: Regulations for waste managementIt is the responsibility of the EMR to ensure compliance with this procedure. The EMR has overview management responsibilities for monitoring, controlling and minimizing waster water discharges. It is the responsibility of the EMR to ensure that all personnel in their areas of responsibility are aware of wastewater discharge management provisions and are familiar with this procedure and regulations.

Identification and Characterization:

Provides for the Minister or competent authority at the provincial level to make regulations regarding waste management (see below).

  • All wastewater discharges must be identified and characterized. This includes storm water discharges also.
  • A drainage plan must be established and maintained which shows.
  • The rout of all industrial sewers and storm water sewers
  • Referenced discharge points/surface drains to sewers
  • Designated sampling points.
  • The destination of the industrial and storm water sewers must also be identified and referenced on the plan.
  • An inventory of all wastewater discharges must be maintained, which cross-references the drainage plan and describes:
  • Sources of wastewater
  • Composition of wastewater, including physical parameters such as temperature, PH etc.
  • Discharge point reference.
  • Designation. I.e. Trade effluent versus storm water run-off

Quantification and Monitoring of Discharges

In addition, a set of minimum requirements for the management of waste and waste disposal sites (see below).

  • Trade effluent shall be monitored on a monthly basis and will comprise grab sampling from the designated sampling point, adjacent to off-site discharge. Monitoring parameters will concur with those contained within the Anglican Water Trade Effluent. Discharge consent. The Production Manager may specify further parameters as appropriate. All exceeding must be recorded and corrective action taken as necessary.
  • Storm water discharges shell is monitored on a bi-annual basis for.
  • Total petroleum hydrocarbons
  • Volatile organic
  • PH in Wastewater Disposal
  • Suspended solids
  • The designated sampling point will be used to measure storm water quality.

Managing & Minimizing Discharges

Regulations have been drawn up under the Section 24 regarding refuse removal in the form Auto Group area (see below)

  • Auto Group have a dual obligation in terms of this section.
    Auto Group may only dispose of waste at a licensed waste disposal site.
  • All discharges from the site will be managed so as to minimize quantities and/or environmental impact.
  • Ways of reducing discharges in both volume and contaminant loading must be identified by:
  • Identifying alternative processes or substances
  • Identifying pollution control equipment
  • Implementing work procedures to control and minimize contaminant loading
  • The EMR will consult with the Production Manager on any proposals to implement discharge control measures.
  • No chemicals are to be disposed of down surface water or sewer drains in exceeding of permit limits.
  • No hazardous materials are to be stored close to storm water drains.

Conclusion

Auto Group are required to provide waste disposal facilities for residents of the municipality. All waste disposal sites run by the Auto Group must be licensed by the Department of Water Affairs and Forestry.The EMR will conduct monthly inspection of the facility to cheek operation practices conform to controlling Wastewater Disposal, these must be recorded in a logbook and any observations documented, together with corrective action. Corrective action which is not immediate (e.g. installation of equipment) must be fully described to include costs responsibilities and dates for completion. Confirmation of completed action must be documented and kept with the logbook. DWAF) any waste disposal facility operated by Auto Group has to comply with the Minimum Requirements

ETP Water Management System for Textile

ETP Water Management System for Textile

ETP Water Management System

ETP Water Management -No development is possible without the application of water. As a result, the demand & scarcity of water is increasing everywhere. Huge amount of water is required in fabric processing. Auto Textiles Ltd. (ATTL) is committed to follow the guidelines of Environment Conservation Act, 1997 (E.C.R’97) and its Environmental Management System (EMS) with a view to maximize the proper use of water and minimize the misuse & pollution of water thereby. aaaa

Development is a continuous process & water consumption cannot be decreased drastically. We are taking ventures regarding all wet processing sectors and trying to bring a change in proper water consumption. We use our merits; do process reengineering & technology assessment and spread awareness among stakeholders to bring the water usage at an optimum level. We are putting our continuous efforts to stop water misuse & pollution and to minimize water consumption. We want to make all our fabric processing functions   maximum water efficient. The main pillars of our water management plan are mentioned below-

We will encourage recycling of waste materials and discourage the use of environmentally unfriendly products. In implementing the policy, we will:

  • Ensure compliance with relevant Environmental Legislation and Regulations.
  • Incorporate environmental considerations into our practices with regard to the use of natural resources, energy consumption and waste disposal.
  • Seek to ensure environmental awareness and responsibility on the part of our staff, our suppliers and partners in the implementation of projects, in facilities, management and operations.
  • Remain committed to prevent pollution.

We will continuously monitor and improve our environmental performances.

ETP Water Management  is very conscious about resource use and management. Water is a very important & essential natural resource. Application of huge amount of water is undeniable in fabric processing trade like textile & washing. Considering the importance & scarcity of water and to comply with national Environmental Conservation Rules 1997 (E.C.R’97), Auto Textiles Ltd. has formed Water Management System for proper water use and management. Following issues are maintained & monitored through our water management system-

  • All legal laws and regulations (E.C.R’97) regarding water usage should be followed.
  • Proper water use should be encouraged, maintained & documented.
  • Misuse or excessive use of water should be brought under control.
  • Fabric processing design should be modified and smart technology should be engaged in order to decrease water consumption.
  • Wastewater should be treated by ETP (Effluent Treatment plant).
  • Reduce, Reuse & Recycle practices have to be implemented (where possible) and should be brought under considerations for future provisions.

The demand and scarcity of water is increasing day by day. Implementing our water management system, we may be able to become smarter about water usage, consumption and to follow concerned rules & regulations cogently.

Statement of the problem

There are various aspects/scope of water consumption in fabric processing. We always try to figure out where and how much water consumption can be minimized. Primarily water saving chances is evaluated and initiatives are considered whether to implement or not.

Water consumption records

Without complete and accurate data & information,  no management step or action can be implemented. We always collect all data available regarding water use and resource utilization.

Inlet- outlet flow  meter

Without measuring, nothing can be managed. For that reason, water flow / consumption record is kept through our outlet-inlet measuring devices.

Initiatives taken by other textile enterprises

Every textile enterprise tries to find out ways or takes initiatives, which may help to save natural resources like water and other. We always look forward if any better initiative is found available or in practice.

Data Collection

If any better initiative is ever found in practice, we engage our merits and research / environmental management team to collect data so that we may follow that good initiative or do something better.

We are not the best in the class. There are other concerns, which are also doing better than we are. We must always compare ourselves with the best of the bests so that we can set our targets towards improvement & development.

Conclusion

ETP Water Management -Going through all the above-mentioned processes, recommendations are screened out and worthy actions and plans are implemented.

What is Electrocoagulation Water Treatment System Tank?

What is Electrocoagulation Water Treatment System Tank?

Electrocoagulation Water Treatment System

The electrocoagulation water treatment system process is based on valid scientific principles involving responses of water contaminants to strong electric fields and electrically induced oxidation and eduction reactions. This process is able to take out over 99 percent of some heavy metal cations and also able to precipitate charged colloids and remove significant amounts of other ions, colloids, and emulsions. Electrocoagulation water treatment system is based on the reactive anodes principle. It is a question of generating metallic cations (Al3+ or Fe3+) in wastewater by imposing a D.C. current between the electrodes. These cations act as a coagulant and lead to the destabilization of suspended particles and colloidal structure.

During the treatment, electrolysis reactions between the electrodes make it possible to produce micro bubbles. These finely divided bubbles drag suspended matter with them as they rise to the surface: hydrocarbons, oils, greases and colloids. At the end of the process, treated and decontaminated water is obtained. Electrocoagulation water treatment system is a technology that can be useful to all industries generating mineral or organic pollution. This Technology is ideally suitable for treating Textile Dyes Effluent

electrocoagulation water treatment
Electrocoagulation water treatment

Electrocoagulation is the process of destabilizing suspended, emulsified or dissolved contaminants in an aqueous medium by introducing an electrical current into the medium. The electrical current provides the electromotive force to drive the chemical reactions. When reactions are driven or forced, the elements or compounds will approach the most stable state. Generally, this state of stability produces a solid that is either less colloidal and less emulsified (or soluble) than the compound at equilibrium values. As this occurs, the contaminants form hydrophobic entities that precipitate and can easily be removed by a number of secondary separation techniques.

Electrocoagulation is an Unique and Latest technology successfully implemented in Developed and Developing Countries. The Advantages of electrocoagulation water treatment system ETP are as follows.

No addition of Chemicals, Lime or Ferric.

Very Low Operating Cost.

Less requirement of Space and Civil Construction.

Easy to maintain and operate.

Colour Removal more than 95%.

Electrocoagulation Water Treatment Process

Electrochemical techniques are important for the treatment of Textile   wastewater because they present high efficiency, easy operation and environmental compatibility; this process involves in sit generation of coagulants by electrolytic oxidation of a sacrificial anode (iron) by applying a direct current. The most widely used electrode materials in electro coagulation process are  iron. The hydrolyzed iron  ions can form long chains of Fe-O-Fe-OH which may chemically adsorb a large amount of contaminating .For most applications a proper removal of all impurities ( Physical, biological and Dissolved impurities) of the water reused, is required.

After biological treated water is secondary clarifier  and remove suspended particles and fed in to electrocoagulation water treatment system. The electro coagulation process works at  input feed  PH is 6.0 to 8.0 and conductivity >2000 milligrams/litre. Before and after were monitored for color, turbidity, pH and chemical oxygen demand reduction efficiency. Normally electro coagulation process  reduces  COD  50 to 60 %  from input COD of  electrocoagulation water treatment system process .

Working principle

  • Dissolution of metal ions from an electrode by applied potential.
  • Simultaneous evolution of H2 gas bubbles.
  • Destabilisation of suspension coagulation.
  • H2 bubbles promote flotation, but also sedimentation may occur.
  • Pair(s) of Fe or Al parallel plate electrodes separated by a few mm.

Electrocoagulation Chemical reaction

Electrocoagulation Chemical reaction

Main reactions occurring at the electrodes are:

Electrocoagulation Chemical reaction 1

In addition, Fe3+ and  OH- ions generated at electrode surfaces react in the bulk waste water to form ferric hydroxide:

The iron hydroxide flocs act as adsorbents  and /or traps for pollutants and so eliminate them from solution.

Electrocoagulation Merits

Overall, compared to conventional methods of treating wastewater involving physical and biological processes, electrocoagulation water treatment system is generally considered far more effective in removing pollutant. Not only that, it is also compact and space-saving and while there are arguments in terms of cost calculation, but however, to most experts’ opinion, it is actually cheaper to maintain in the long run.

Electro coagulation process (using iron electrodes) is a reliable, efficient and cost- effective method. quickest removal rate  with the lowest cost.

Before start up EC PROCESS the operator must check EC input effluent PH ,it should be always greater than 6.5 and less than 8.5.

EC operates at PH  6.5 TO 8.5 .

Every day before start up, EC the operator must clean EC skid with HCl. The operator should maintain the PH of the diluted Acid as less than 2.0. If the cleaning acid PH greater than 2.0, must drain old acid(high PH acid > 2.0)  and fill new hydro choleric acid  and clean EC skid.

Every day  The operator’s every one hour once give air circulation in to EC SKID .

Before start EC skid the operator must prepare poly electrolyte dosing chemical.

The operator must  dose poly electrolyte 2 to 2.5 ppm in EC outlet water.

Every day The operator always take chemical stock list and material stock list (EC PLATES ).

If EC plant stop, the operator must drain EC skid water and  well rinse EC SKID with treated water .

Every day the operators note EC voltage and current value and record it separate  log sheet.

The operator every one hours once check EC TREATED WATER QUALITY. if water quality is not good increase current value and set  correct current value. IF treated water more green color present  reduced  EC skid current value and  set correct current value.

Conclusion

Every day once the operator must prepare poly electrocoagulation water treatment system dosing. Normally 5 to 7 days once the operators must change  used cleaning acid   or Acid PH greater than 2.0 change the cleaning acid. When EC PLATE changing  period the operator must note EC plates are sited  in the mounding grid  properly. It is very essential for any textile industry.
