How it works

The Platinum Process

Primary Settlement

Sewage from the home flows into the primary chamber. Initial settlement and separation of gross solids occurs. A sludge layer is formed at the bottom of the tank which should be removed periodically. The settled effluent passes forward for treatment in the biological zone.

Submerged Aerated Filter (SAF)

The media in the biological zone provides a large surface area allowing natural growth of microorganisms (biomass). Oxygen is supplied to the zone through dedicated air diffusers at the base. The microorganisms require oxygen to develop and in turn reduce the levels of biological oxygen demand (BOD) and Total Suspended solids (TSS) in the effluent to <25:30 mg/l BOD:TSS.

Final Settlement

Further settlement occurs reducing the levels of suspended solids. Settled solids are returned via an automatic sludge return system to the primary settlement chamber for storage.

Tertiary Treatment

The Platinum SAF treatment system can be followed by the Puraflo polishing filter. Severe sites, environmentally sensitive sites, sites in watershed protection areas, or areas where effluent will be reused often require enhanced treatment.  This treatment will achieve a 5:5 mg/l BOD:TSS standard and significant pathogen and nutrient reduction.
