WATER TREATMENT

Ensign:Ultra

Economical and highly efficient, the Ensign:Ultra packaged sewage treatment plant is reliable, quiet and compliant. The end-effluent is clear and safe to be discharged into watercourses. We recommend this product to anyone thinking of replacing a septic tank with a PSTP. The Ensign:Ultra, manufactured by Marsh, is so effective it removes 97 per cent of pollutants.

This product complies with BSEN12566-3/A1:2009. It is available in a range of profiles and sizes to suit different ground conditions and capacity requirements.

Widely used in domestic settings, this product comprises: an inlet with a primary settlement chamber, a robust aeration chamber, compressor complete with alarm, full compressor housing, electrical connection and PVC pressure pipe , bio-media and stainless-steel mesh, a final settlement chamber and sludge return. It also benefits from a Polylok tertiary filter and outlet and access lid.

For ease of installation, this sewage treatment plant benefits from built-in lifting eyes and has  an industry-leading keying-in lip and stabilising feet. Because of its advanced Polylok filter, this sewage treatment plant is suitable for effluent destined for either drainage fields or water.

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. Advanced compressor with alarm
Near silent compressor ensures 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. RCD / Electrical connection
The RCD box provides easier installation and a higher degree of safety.

7. PVC pressure pipe / 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. Unique Polylok tertiary filter (Ensign:Ultra unit only)
The Polylok tertiary filter reduces suspended solids and BOD by a further 40% helping to extend drainage field life.

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

14. Impermeable lid
Heavy duty lid/frame improves strength and durability whilst blending into the surrounding environment.

Operating principle

In addition to anaerobic digestion taking place in the primary settlement chamber [2] the Ensign:Ultra 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.
