Effluent Treatments & Recovery Plant – 40 KL/H

Problem Statement

Our client is a leading Manufacturer of edible oils in South Africa. The edible oil manufacturing process produces large volumes of oil-contaminated wastewater which needs to be transported off-site for treatment since it poses serious environmental risks.

Solution

Watericon designed, built and commissioned a two-phase effluent treatment & recovery plant. The first phase consisted of Settling and DAF to remove solids. The second phase involved polishing of the filtrate from phase 1 for use in the boilers, cooling towers and as process water.

Typical Plant Feed

  • SOG>1 000 mg/L
  • SS >100 mg/l
  • TDS >10 000 mg/l
  • COD >20 000 mg/l
  • 30m3/h

Performance Target

  • SOG> 0 mg/L
  • SS < 0 mg/l
  • TDS <100 mg/l
  • COD < 0mg/l
  • 25m3/h

Process

  • pH Correction
  • Coagulation & Flocculation
  • Settling
  • Dissolved Air Flotation
  • Media Filtration
  • Reverse Osmosis

Innovation

Our process drastically reduced the client’s waste volumes, as well as basically eliminated client’s reliance on municipal water supply. Our client can now utilize their RO to treat water from an existing borehole to supplement their usage.
