Wet on dry application
For stenter padder tray, it needs minimum 80 liter liquor to dipping the fabric. For wet on dry application consider 90% pick up. So total liquor will be, 90% of fabric weight plus minimum padder tray liquor. Then calculate dosing of chemical.
For example
100 kg fabric needs 90 LTR liquor plus minimum padder tray liquor= 80 LTR,
So total liquor required= (90+80) LTR= 170 LTR
If the chemical dosage is 25 g/l, then total chemical will be 170*25/1000= 4.25 kg.
CHEMICAL EQUATION OF CONFIDENT
ELECTRO-COAGULATION WASTE WATER TREATMENT SYSTEM
By inducing DC pulses in the Electrodes, the following reactions happen in the Electro-Coagulation system.
There is no addition of any chemicals for the Coagulation.
AT ANODE
Fe Fe 2+ + 2e-
(IRON) (FERROUS) + 2ELECTRONS
AT CATHODE
2H2O + 2e- H2 + 2OH-
(WATER) + 2 ELECTRON (HYDROGEN) + 2 (HYDROXIDE)
Fe2+ + 2OH- Fe(OH)2
FERROUS + 2 HYDROXIDE FERROUS HYDROXIDE
Fe(OH)2 acts as the Coagulant and separate the dyestuff and other contaminants.
DYESTUFFS IN THE WASTE WATER CHEMICAL FORMULA IS 2R-SO3-Na
R—SO3—Na
2R-SO3-Na + Fe(OH)2 = Fe + 2NaOH
R—SO3—Na (Dissolved in water)
DYESTUFF + FERROUS HYDROXIDE = SLUDGE + 2 SODIUM HYDROXIDE.
THE ADVANTAGES OF THIS SYSTEM ARE AS FOLLOWS.
1. NO CHEMICAL COAGULANTS USED.
2. OPERATING COST IS VERY LESS.
3. EASY TO OPERATE AND MAINTAIN.
4. BOD AND COD REDUCED BY 60 – 70%
5. TDS AND HARDNESS NOT INCREASED.
6. COMBINED WITH PARTIAL BIOLOGICAL SYSTEM, COMPLIANCE OF ALL THE POLLUTION CONTROL NORMS ARE ACHIEVED.

Necessary standard requirement of dyes chemical for buyer garment Dye and wash orders.
Dear Sir’s,
Hope you are aware of that your company is supplying different laundry chemicals to us for quite sometime.
And now it is for your kind information that one of our most important buyer Has got some chemical restrictions which are not at all allowed and untolerable at any time In their washing purpose.
So, if any of your supplied chemical may identified as restricted for use by chemical Analysis department, then buer will charge a huge claim on both of us and they will Cancel our job nomination. Which will be subject of very big business loss for both us. And now sorry to say that we will definitely claim such loss on you by the court of law.
So, please take all necessary action required to avoid and to prevent such situation.
Best regards,
Mr. Rahaman
Managing Director
