Effective Treatment of Black and Grey Water

Four-step biological sewage treatment process applying the 5 SHIN ^® Technology

STEP 1

Pump Station
Collect all sewage and waste water from the settlement. Separate and digest faecal solids to facilitate delivery of a largely solids free effluent.

STEP 2

Bio-Reactor Tanks
Reduction of the total nitrogen and organic load occurs in the anoxic / bioreactor. An aerobic fixed film process oxidises residual organics and provides an environment for a nitrifying bio-film. This is where nitrification and de-nitrification occurs.

STEP 3

Clarification Tank
Separation of sludge (at the bottom of the tank) and clear water (top of tank)

STEP 4

Sterilization Tank
Treatment of the clear water either by Ozone or Ultraviolet technology, resulting in clean, odourless and environmentally-friendly water, ready for recycling.
