The Biocycle treatment system is typically a single, moulded concrete tank, with five internal chambers. Each chamber has its own specific task in the treatment process. The technical name for this type of system is 'AWTS' - Aerated (or Advanced) Wastewater Treatment System.

The first two Primary Treatment chambers allow floatation of fats, while naturally occurring anaerobic bacterial organisms digest solids. Any sludge settles to the bottom. The mid-water is the cleanest and flows into the third Aeration chamber. 

The Aeration (Secondary Treatment) chamber hosts naturally occurring aerobic bacteria, which grow on a special media framework we install. Multiplying or diminishing as required by flow rate and available 'food' (suspended solids), these bacteria consume suspended organic particles, resulting in clear and odourless treated effluent flowing to the final stage within our forth Clarification chamber. Any remaining microscopic sediment (activated sludge) settles to the bottom, then is sucked up and returned to the first chamber for re-treatment. 

The fifth chamber has a high-quality energy efficient pump installed, designed especially for human effluent discharge. This pump turns on automatically by float switch when required, and discharges clean nutrient rich water which can now be utilised as a valuable irrigation resource for trees and landscaped gardens, or soakage into lawns.  

As a nation, we need to address and improve our environmental impact, so future Kiwis can enjoy swimming in and drinking from our precious streams and rivers. While other industry sectors focus on cleaning up the agriculture and horticulture industries, we at Biocycle are proud to focus our efforts on cleaning up human wastewater and converting toxic pollutants into a valuable clean and natural irrigation resource for home gardens.
