Dear gaffar,
Can you share with us your influent and effluent characteristics (pH, BOD, COD, TSS, Turbidity, Color, Starch, flow, DO), along with treatment scheme. Your COD and TSS both would be high. There is no rule of thumb for dosage optimization of lime, alum, poly and colour removal chemicals. It should be jar tested at lab for optimum permutation and combination for getting the desired result. The ideal dosage for Color removal chemical can go up to 1000 ppm depends upon the quality of waste water and treatment scheme. Please note CRC is not cheap. It will add high treatment cost per annum.
We have seen several factors contributing to high COD and most of the technology failed in meeting the discharge norms. I can solve your issue please share the details with me. You can reach me at sushantkuma@gmail.com.
