WATER TREATMENT

Shallow Ensign:Ultra

We recommend Shallow Ensign Ultra sewage treatment plants for areas where hard rock is present in the ground or where installing a deeper tank would prove problematic. This treatment plant is just 1.6 metres tall, meaning it is safe to install anywhere. It is highly effective, removing 97 per cent of pollutants. Effluent is safe to be discharged into water or drainage fields. Ideal for domestic use where a packaged sewage treatment plant is required.

This plant meets BSEN12566-3/A1:2009 and is available in sizes from 4 to 50 PE. As well as being economical to run, the plant requires little maintenance.

What you get with the Shallow Ensign: Ultra: A sewage treatment plant that can be installed anywhere. It delivers effective anaerobic digestion from the first chamber, a second aeration chamber and efficient removal of dissolved pollutants. A final settlement chamber is used before clear effluent is discharged via a Polylok filter.

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.
