RESIDENTIAL TREATMENT

Oasis Aerated Systems

Oasis Aerated Systems utilises settling, filtration and aerobic digestion to process the effluent. Developed in New Zealand for New Zealand conditions, the Clearwater Series quickly and efficiently turn all your household waste water into high quality irrigation water, saving your valuable water supply for more appropriate uses.

Why is the Clearwater Series Technology so effective?

oasis-aerated-illustration-sm
The Clearwater Series 2000 system is not a septic tank! It is an aerated waste water treatment system comprising five stages of treatment. Liquid flows through the system by hydraulic disbursement.

Waste water first enters a pretreatment, settlement chamber. It then flows into a secondary settlement chamber. From here it passes via a revolutionary ZABEL A300 high performance filter, where further biological and mechanical filtration occurs, into the central aeration chamber.

In the central aeration chamber, thousands of tiny air bubbles are created by our exclusive Series 2000 fine air diffuser assembly, constantly mixing the contents and providing essential oxygen for the aerobic digestion and cleansing process.

The process continues as the water is introduced to our unique Clarifier unit prior to flowing into the pump out chamber.

The system is complete with a high quality system malfunction alarm.

Textile Advanced (TEXASS) Systems

oasis-aerated-006-sm

Oasis TEXASS Systems utilises a textile media to efficiently filter the effluent over multiple passes.

Developed in the USA and perfected in New Zealand, the Texass (Textile Advanced Sewage Solution) utilises a textile media to efficiently filter the effluent over multiple passes, finally producing a very high quality end product that is ideal for irrigating lawns, gardens and tree lots.

Residential Membrane Bioreactor MBR

The Oasis MBR is one of the finest Membrane Bioreactor filtration wastewater treatment systems available today. Our system converts the sewage from your residence or business into a clear, odourless liquid. The high degree of treatment is accomplished at a remarkably low operating cost per month.

Membrane Bioreactor technology has a number of inherent advantages. The principle of the operation does not require flocs to be formed to remove the solids in sedimentation and therefore the Biomass can operate at very high levels of Suspended Solids. This reduces sludge volume - allowing for smaller tank size and accordingly a smaller footprint.

Advantages of the Membrane Bioreactor

Septic Tank Systems

The Oasis Septic Tank & Treatment Systems are based on the tried-and-tested principle of separating solids from liquids. The point of difference for Oasis is the 3-chamber configuration of the septic tank system. This introduces a second stage of settling and allows further anaerobic breakdown to occur. Finally the versatility of the Oasis Septic Tank & Treatment Systems allows for 3 options of dosing the treated sewage to occur, via a pump and float switch, a flout or via tried-and-tested gravity feed. The Oasis Septic Tank & Treatment Systems has a treatment capacity of 4,800 litres.
