5 shin® technology

The design of the Bio Sewage Systems (Flush n Spray® Range, BioBEE Modular Range and the Container plants) enables the effective treatment of black and grey water streams using a modular, simple and robust technology, with minimal mechanical components, which has the ability tolerate high peak flows.

The 3 stages of sewage treatment:

  • Reduction of the organic load using predominantly an anaerobic process.
  • Reduction in the nitrogen load.
  • Reduction in the pathogen load.

The four-step biological sewage treatment process applying the 5 SHIN® Technology :

STEP 1

Collecshin
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

Nitrificashin
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

De-nitrificashin
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 4

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

STEP 5

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

 

The process is as follows:

  • The raw sewage is channelled to a submerged tank where non-biodegradable products are separated. (Old septic tanks can be retrofitted for this process).
  • The sewage is then pumped into the first reactor tank which contains bacteria growing on media and where the nitrification takes part.
  • From the first nitrification reactor tank, the sewage then moves into the second reactor tank where de-nitrification occurs, also with bacteria reaction.
  • Then the effluent flows into the cone-shaped clarification tank where any solids that escape the first 2 tanks are collected and pumped back to the first tank to start the process again.
  • From the clarification tank, the now clean and treated water overflows into the last tank where sterilisation occurs using ozone or Ultra violet.
  • In the sterilisation tank is a submersible pump which will automatically pump the treated water to irrigate, to enter game watering holes, etc.
