WATER TREATMENT

Marsh Ultra:Polylok L – 6 and 12

Order a Marsh Ultra:Polylok L if you are looking for an advanced sewage treatment plant. Designed to meet the needs of off-mains waste, it uses submerged aeration filtration to deliver clear effluent that is safe to be discharged into watercourses. This filtration system uses Gaia Sege© Process design software developed by Marsh to maximise the benefits of sewage treatment. We supply this plant in 6PE and 12PE models, both approved to BS EN12566-3. It achieves effluent treatment to 20:30:20, making it completely compliant.

This sewage treatment system comprises: an inlet, initial or primary chamber, aeration chambers with diffusers, a final chamber and is supplied with a high-performance Polylok filter, outlet and recirculation.

The sewage treatment plant is further supplied with a turret guard, carbon covers, high level alarm, all necessary compressors and a GRP kiosk.

This product is available in a choice of specifications suited to commercial, domestic and industrial use. It is highly recommended for those looking to achieve total treatment and the cleanest possible effluent. If you are looking for an alternative to a septic tank ahead of regulation changes in early 2020, this product won’t let you down.

Operating principle

The UPL uses a similar operating principle as the Marsh:Ensign.

In addition to anaerobic digestion taking place in the primary settlement chamber [2] the UPL 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 [8]. The final effluent is then discharged to the drainage field or watercourse via a Polylok filter.
