The entire ZLDS process is designed scientifically and being executed in a systematic process utilising cutting-edge technology procedures and equipment by experienced professionals. The combined effluent water will be in dark colour at the initial stage with the PH level at 9 to 11. The total dissolve solids will be varying between 5000 to 6000 mg/ltr. The total suspended solids will be at 200 mg/ltr. The COD will be 1500 mg/ltr, whereas the BOD will be 300 mg/ltr. These levels will be significantly reduced in the case of PH levels and total dissolve solids, whereas the water will be colourless and total suspended solids, COD and BOD will all be totally eradicated at the final processing.
