WATER TREATMENT

Shallow Ensign:Standard

The Shallow Ensign:Standard sewage treatment plant is the preferred option for those who require a PSTP without a Polylok filter. It uses a three-chamber filtration system to deliver clear effluent. Wastewater is treated to remove 97 per cent of pollutants. Ideal for installation in areas where the ground is hard, this treatment plant is just 1.6m in height. It uses a tried and tested filtration system to ensure the resulting effluent is safe to be discharged.

We recommend this packaged sewage treatment plant if you are looking to replace a septic tank or cesspool before regulations change in January 2020. This three-chamber plant is highly efficient and cost-effective. It is suitable for a wide range of environments and is popular with our domestic customers. This product complies with BSEN12566-3/A1:2009, is easy to install and straightforward to maintain.

Benefits
1. Inlet with ‘Forsheda seal’
Forsheda seal provides flexibility in the joint for easier installation.
Optional risers to increase invert depth are available.

4. Compressor with alarm
Low-energy compressor provides minimal running, maintenance and servicing costs. Integral alarm detects low pressure in air line.

5. Compressor housing (External or internal options)
The compressor can be housed internally or externally with no difference in cost. External recommended to increase compressor life, and supplied as standard on 4PE, shallow and pumped outlet versions.

6. Plug / socket connection
Standard electrical connection

7. PVC pressure pipe for diffuser(s)
Provides a protective conduit for the air diffuser line. Can be easily removed for maintenance and cleaning.

8. Bio-media
High specification bio-media (310m3 per m2) and membrane diffusers ensure even circulation to eliminate ‘dead spots’. The bio-media is contained by a stainless steel securing mesh to ensure no migration during handling or potential flooding.

9. Stainless steel mesh
Retains media in aeration chamber during transportation and handling, and in the event of flooding.

11. 32mm sludge return
Larger diameter sludge return prevents the possibility of blockages and improves system circulation. Provides higher effluent quality whilst balancing flow over a 24 hour period or periods of intermittent use.

12. Polylok tertiary filter is NOT supplied on Ensign:Standard range

13. Outlet with ‘Forsheda seal’
Forsheda seal provides flexibility in the joint for easier installation.
Optional pumped outlets are available.

14. Standard lid
Marsh lid protects inner components whilst blending into the surrounding environment.

Operating principle

In addition to anaerobic digestion taking place in the primary settlement chamber [2] the Ensign unit allows the clarified water to pass into a second ‘aeration’ chamber [3] where it is treated to remove the dissolved constituents. Here aerobic bacteria, supported by diffused air and mobile media, ensures full treatment is achieved before the treated effluent and ‘sloughed off’ bacteria flows to a final settlement chamber [10]. The final effluent is then discharged to the drainage field or watercourse via a Polylok filter.
