Zero Liquid Discharge Solution developed for Chromium contaminated high TDS effluent from leather industry.
Overview of Company:
The Client is one of India’s largest leather products manufacturing company based at Ranipet, Tamilnadu. The company is manufacturing different products in the plant and they mainly export their production.
Inlet Effluent Detail:
pH : Neutral
TDS : App 25000 ppm
Objective of the plant:
To reduce the TDS sludge generation
To evaporate the effluent and set up a Zero Liquid Discharge unit
Before Applying the Algae Technology: The High TDS effluent (RO reject) was taken to the solar evaporation ponds where they have to evaporate through solar evaporation. The solar evaporation rate is very low and they have to use very large tracts of land. Also as the TDS gets concentrated in the pond, the evaporation rate drops. Also they end up with lots of TDS sludge in the evaporation Pond.
After Applying the Micro Algae: In the Pilot plant of 1 KLD evaporation, we have got following results
1) TDS Sludge Reduction
2) Chlorides Reduction
