Introducing the latest innovation in domestic sewage treatment technology, the Marsh Ultra:Polylok L (UPL).
The UPL draws upon Marsh Industries’ extensive experience in the industrial and commercial sewage treatment sectors bringing its outstanding performance and added-value engineering to the domestic sector.
The Marsh UPL is available in 6PE and 12PE models, is approved to BS EN12566-3 and carries an impressive effluent quality of 20:30:20, within national consent standards.
End users, merchants and installers alike recommend the UPL 6 or 12 due to its compact shape, ease of installation, reliability, and cost-effective operation and maintenance. All backed by technical support from local contacts.
The UPL uses a similar operating principle as the Marsh:Ensign.
In addition to anaerobic digestion taking place in the primary settlement chamber  the UPL unit allows the clarified water to pass into a second ‘aeration’ chamber  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 . The final effluent is then discharged to the drainage field or watercourse via a Polylok filter.
