Advanced Technology Waste Water Disposal Systems: Biocycle System

What Is a Biocycle System?
Picture of Biocycle
The Biocycle Model 5800 (AWTS) domestic system as used in individual households, replaces the septic tank and is unaffected by geographic / climatic locations, operating in the extreme heat of Western Australia to the icy winters of Anchorage, Alaska.

Biocycle treats all household wastewater right on site, in a four chambered, fully self-contained

system and discharges clear, clean effluent suitable for irrigating lawns and non-edible gardens. Unlike septic tank systems, effluent discharged from a Biocycle system is clear and fully treated.

The Biocycle Model 5800 is made of triple wound reinforced fiberglass for maximum strength and is designed to treat flows of up to 2,500 litres per day.

How Does Biocycle Work?
Biocycle diagram 1. PRIMARY, ANAEROBIC CHAMBER
Biocycle's primary chamber serves as both a flow-balancing chamber and as an anaerobic (without oxygen) treatment chamber. All wastewater leaving the residence enters the chamber, where anaerobic bacteria begin the digestion process. Unlike a septic tank which discharges partially treated sewage directly to
the environment, Biocycle continues the treatment process in the next chamber.

2. SECONDARY AEROBIC CHAMBER

From the primary chamber, wastewater flows into the secondary chamber where aerobic (oxygen consuming) bacteria take over and complete the task of digesting organic material. A large surface area of bacterial growth media provides a base upon which bacteria live. Oxygen required for the process is provided by an air blower, which diffuses air into the chamber. The bacteria consume the nutrients in the sewage to fuel their growth.

3. CLARIFICATION CHAMBER
Following secondary treatment, the now much clearer wastewater moves to the clarification chamber, where a sludge return system picks up any organic materials remaining in the fluid and returns them to the primary chamber for re-treatment. This re-treatment process also creates an environment where nutrient reduction occurs.

4. DISINFECTION UNIT
From the clarifier, if required, wastewater flows through the system's disinfection unit and into the irrigation chamber. Biocycle currently uses either a chlorinator or a germicidal Ultraviolet light, depending upon local regulatory requirements.

5. IRRIGATION CHAMBER
The final section in a Biocycle system is the irrigation chamber, where the treated effluent is retained awaiting periodic automatic discharge to an irrigation network, or disposal field.
