What is Digital TDS Meter Online ?

Digital TDS Meter

  • Switch ON the instrument , wait till its warm up
  • Adjust the temperature setting knob to room temperature
  • Set the check value as 1 .000
  • Wash the electrode by DM water
  • Dip the electrode 3000 PPM TDS calibration solution.
  • Adjust the reading to 3000 by using calibration knob of digital tds meter online
  • Rotate the knob to cell constant
  • Note the cell constant reading of tds meter online
  • Before going to check the sample , cross check the cell constant
  • Using the range knob we can measure the sample.
  • Instrument in stand by time rotate the switch to check position
  • Prepare 3000 PPM solution weakly once using sodium chloride or KCl

Prepation Of 3000 Ppm Solution

  • Dry the Nacl or KCl AR grade in the oven at 105’C for 1 hr
  • Cool & Weigh accurately 3 gm and dissolved in 1000 ml of DM water
  • Check the 3000 PPM solution in evaporation method using oven
  • Conformed TDS value used to calibrate the instrument

 

Total Solids Determination -TS

  • Weigh the weight of china dish and note as W1-gm
  • Take 10 ml of sample in china dish
  • Set 102 ‘ C in oven and switch on the oven & recirculation fan
  • Kept the sample in the oven for 1½hours at 102 ‘ C
  • After 1½ hours take away the sample from oven and kept in desiccators
  • For ½ hour allow to cool room temperature of Digital tds meter
  • Note the final weight of china dish W2-gm
  • Calculate the weight of solid W =  W2 – W1

TOTAL SOLIDS =        weight of solid W x 1000 x1000    PPM

  • Volume of the sample

 

Total Dissolved Solids Determination-TDS

  • Weigh the weight of china dish and note as W1-gm
  • Take 50ml of sample in a clean beaker and filter this sample by using what man NO 1 filter paper.
  • Discord first 10 ml of filtrate, then collect the filtrate in the beaker
  • Take 10 ml of filtered sample in pre -weighed china dish
  • Set 102 ‘ C in oven and switch on the oven & recirculation fan
  • Kept the sample in the oven for 1½hours at 102 ‘ C
  • After 1½ hours take away the sample from oven and kept in desiccators
  • For ½ hour allow to cool room temperature
  • Note the final weight of china dish W2-gm
  • Calculate the weight of solid W =  W2 – W1

TOTAL DISSOLVED SOLIDS =        weight of solid W x 1000 x1000    PPM

Volume of the sample

 

Total  Suspended  Solids Determination -TSS 

TOTAL SUSPENDED SOLIDS TSS =   TS – TDS    ppm

 

Determination Of MLSS / TSS

  • Weigh the weight of What man 41 filter paper note as W1-gm
  • Take 25 ml of aeration sample in a measuring cylinder
  • Filter this sample by using what man 41 filter paper.
  • Take the filter paper carefully and placed in china dish
  • This sample Kept in the oven for 1½hours at 102 ‘ C
  • Set 102 ‘ C in oven and switch on the recalculating fan
  • After 1.5 hours take away the sample from oven and kept in desiccators
  • For ½ hour allow to cool room temperature
  • Note the final weight of filter paper W2-gm
  • Calculate the weight solid W =  W2 – W1

MLSS –  Mg/Lt                        =        weight of solid W x 1000 x1000

Volume of the sample

NOTE

Volume of sample is 100 ml

MLSS – Mixed liquor suspended solids

 

Determination Of Mlvss Using Muffle Furnace

  • Residues obtained in mixed liquor suspended solids, and note the weight of filter paper W2-gm.
  • Place the filter paper with residue in crucible
  • Ignite the residue  in muffle furnace for 1 hour at temperature of
  • 500-550’ c
  • After 1hour take away the sample from furnace  and kept in desiccators
  • For ½ hour allow to cool room temperature
  • Note the final weight  W3-gm
  • INNERT Mg/Lt =   W2 – W3 x 1000 x 1000

Volume of sample

 

MLVSS           =   MLSS – INNERT Mg/Lt

 

Volume of sample is 100 ml.  MLVSS – Mixed liquor Volatile suspended solids
