effuluent treatment with recycling.
effuluent treatment with recycling.
(OP)
Hi ,
could any one suggest the best available technique t treat textile waste fro dueing and printing and make it recycleable to the process again. I have RO plant available working on well water of 7500 tds. quantity of waste water is 500000 GPD.
awaiting response.

RE: effuluent treatment with recycling.
What else is in the water that you wish to recycle: dye, detergent, bleach..?
Do I understand that your well water is 7500 ppm TDS?
RE: effuluent treatment with recycling.
i would like to use water again from waste nothing else. For well water u understood correct it is 7500 ppm tds.
R.O we are using to purify the water up to 200 tds and less then 17.5 ppm hardness. Same RO i planed to utilise for recycling the waste water.(After color and other things removal from effuluent water.)
Any suggestion.
regards.
RE: effuluent treatment with recycling.
Describe your WWT. Do you floc and settle out solids, use a clarifier, and now wish to use the clear effluent via RO? What is TDS at this point?

RE: effuluent treatment with recycling.
we don't have wwt yet but we are planning for it. We have RO plant which is used for undr ground well water.I am planning to use it for recycling the treated water after treatment plnt we are looking for. The limitation is that biological and physio chemical treatment plants does nt remove the color fully. Hence this water can not be pass through our existing RO membranes(BW30-400). My question is if some knows about simlar plant we are looking for.
My idea is
Filterd waste water go into floculation then cogulation and sedimentation. this will reduce inorganic matters , reduce color and bod cod. Then this water go to biological treament where organic substances are treated with becterias. after this if bod and cod are nil and water is coloer less then we can pass it through our existing Ro to reduce its tds and the final recycled water goes back to our proccess of dying/bleaching.
If any one knows about similar plants operating any part of the world.
RE: effuluent treatment with recycling.
I don’t think the following sequence will do much:
“Filterd waste water go into floculation then cogulation…”
What will filtering remove? Dyes are soluble. Coagulation must precede flocculation. Sequence should be: *add coagulant, flocculate, sedimentation, filtration.
*Maybe biological treatment should be first; it can break down soluble dyes, so subsequent coagulation, etc. can remove metals. If you coagulate w/o biological, your sediment will be highly leachable.
I suggest buying this inexpensive book:
Advances in Industrial Wastewater Treatment by P. K. Goel. 500 pages, $20-22 + ~$3 shipping. About 50 pages on treating textile effluent, plus chapters on treating tannery and distillery effluents, and a review of general processes.

How expensive are the dyes that you use? You may save money on dyes and lower WWT costs if you also buy several smaller RO units as suggested in my first post.
