Enviss Ensep BioSentinel

Decentralised Sewage Treatment

High Capacity, high performance
Enviss systems have a high treatment capacity on a small footprint. The treatment technology is compact and can handle high volumes of water.
Low Energy Use
The Enviss treatment method uses water pumps rather than blowers to more efficiently provide high levels of oxygen to the bacteria. This means lower electricity use and lower running costs.
Above or Below Ground
The Enviss system has been designed to allow for above or below ground installation to suit site conditions.

No Odours
The biological process generates very few odours and these are eliminated using a long life air scrubber. This means no nasty septic odours and a better environment for residents.
Fully Automated
The process is fully automated and only requires weekly inspection. The on board controlled can adjust treatment cycles depending on the load to optimise the bacteria growing conditions.
Quiet Operation
Without blowers the system is very quiet and can be operated 24 hours a day.

When compared to other sewage treatment plants (STPs), the ensep System has the following advantages:

The BioSentinel Treatment Coil treats sewage to remove BOD, COD and nutrients from the influent.
The BioSentinel Treatment Coils consist of a spirally wound membrane supported on a two-dimensional plastic matrix that supports the growth of biofilm on the wet side and provides oxygen by diffusion from the air on the dry side.
By providing oxygen from ambient air, the need for compressed air or blowers is avoided.
The biofilm consumes the pollutants in the water as it grows.
The ensep System works by recirculating water from the bottom reservoir to the top of the coil. At the top of the coil the water is distributed evenly by a spray nozzle and flows back to the reservoir below.
The recirculation pump circulates the water in this manner multiple times to maximise exposure to the biofilm to maximise treatment performance.
