Secondary treatment

Biological treatment systems reduce polluting materials in waste water streams by utilizing micro-organisms. This well established technology is also capable of removing organic constituents such as ammonium, phosphorous, etc.

Today’s regulatory pressures require effluent plants to perform better than ever before. Many industries have traditionally relied on primary treatment processes only for their waste water treatment.

This has performance limitations and may not remove sufficient amounts of polluting material to a suitable level to meet discharge consents or allow water recycling.

KWI biological treatment systems are designed generally for particular cases of industrial effluent treatment where conventional solutions are not applicable or are inappropriate.

Combinations of primary physical-chemical pre-treatment and continuous bioreactors or SBR systems have been successfully used in many difficult cases.
