Zero Liquid Discharge System Process Lifecycle
Zero Liquid Discharge System Process Lifecycle
Our comprehensive ZLDS process is a meticulously designed and systematically executed system that leverages cutting-edge technology and equipment, managed by experienced professionals. At the outset, the combined effluent water exhibits a dark colour with a pH level between 9 to 11. Total dissolved solids range from 5000 to 6000 mg/ltr, and total suspended solids measure at 200 mg/ltr. The COD stands at 1500 mg/ltr, while BOD registers at 300 mg/ltr. As the process unfolds, pH levels and total dissolved solids dramatically decrease, eventually rendering the water colourless and completely eliminating total suspended solids, COD, and BOD, exemplifying the effectiveness of our approach.

Recovery from RO MEE
-
- Based on feed water in RO we can able to recover 90-95% in achieving from RO and MEE
-
-
Sludge Management
-
- Sludge generation from clarifier and aeration we can able to handle through filterpress and decanter
