K H Exports India Pvt Ltd


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


  • Expected Theoretical TDS (as on 5/02/2016) : 134300 ppm
    Actual Tank TDS being maintained (as on 5/02/2016) : 43800 ppm
  •  This data implies that in the absence of algae, TDS would have been 1.36 lacs ppm, but due to the remediating effect of algae, TDS remains at 0.44 lacs ppm.

2) Chlorides Reduction

  •  Expected Theoretical chlorides (as on 1/02/2016) : 44900 ppm
    Actual Tank Chlorides (as on 1/02/2016) being maintained : 18616 ppm

Algae Biomass Analysis Report :



World's First Phycoremediation plant: Dr V Sivasubramanian, has set up the First Phycoremediation plant at SNAP Industry. Algal remediation technology helps in pH correction of the acidic effluent and complete reduction of sludge formation. SNAP is now a zero disposal company. The phycoremediation plant has been in operation from September 2006. The effluent generated by the industry is highly acidic and of very high TDS (40000 mg/L). The entire effluent is evaporated using slope tank with zero sludge formation. The algal biomass produced is used in Biofertilizer preparation and sold by the Company. .......(.more )
