AQUATECH AEROBIC SAND FILTER TREATMENT SYSTEMS   

The Aquatech Treatment System Process
The Aquatech aerobic sand filter system has been developed for the treatment of ALL household wastewater. Unlike septic tanks this total wastewater approach fully includes kitchen, bathroom, laundry and toilet wastes without exception. The wastewater is then processed and "renovated" before being automatically distributed through sprinklers serving lawn and garden areas.

This is the cleverly engineered environmentally friendly alternative to conventional septic tanks systems, yet without the high maintenance associated with mechanical aeration plants. It utilises natural processes of settling and filtration in an environment where organisms beneficial to the breakdown of wastes may flourish.

  A   Step "A" - Wastewater Collection 
Household waste water from kitchen, laundry, bathroom and toilet systems are directed to one common drainage pipe. It's much like being connected to a town sewer system. This "drain" then leads into a large capacity treatment chamber [B]. 

  B   Step "B" - Primary Treatment 
Naturally occurring bacteria start the treatment process by breaking down settled solids through anaerobic digestion. Fats and other light matter float to the surface to form a scum.

Liquid wastewater, which now has had a large proportion of suspended solids removed, flows into a pump chamber where, by simple float-switch control it is pumped onwards and onto a buried anaerobic sand filter.

  C   Step "C" - Secondary Treatment 
Unlike other secondary treatment systems currently available, the Aquatech Treatment System does NOT use mechanical aerators, diffusers, blowers, artificial media material or costly moving parts. Instead, a well designed and carefully constructed buried Aerobic Sand Filter offers secondary treatment and "polishing" of the effluent in a completely natural and inexpensive manner.

The Aquatech Sand Filter has been designed using the engineering principle of Long Term Acceptance Rate (LTAR). This ensures that the filter has a long life without hydraulic surcharging.

Liquid wastewater from a primary pump chamber is dose loaded onto a bed of clean crushed rock. It then slowly percolates down through various layers of specially graded sand and rock.

Physical, chemical and biological processes occur naturally within the Aerobic Sand Filter to remove organic material and most importantly harmful bacteria, pathogens and viruses.

  D   Step "D" - Renovated Water Distribution
The renovated water is collected at the base of the fully lined Aerobic Sand Filter and drained to a pump chamber. It is now ready to be distributed through a fixed or movable sprinkler distribution system onto lawns, gardens or native bushland.
