Klargester Biosafe

Package Sewage Treatment System

The best designs are the simplest. So if you require trouble free sewage treatment, you’re sure to be impressed with the new Biosafe.

Fluidised, fixed-film biozones are used as the operating process, resulting in a cleaner, quieter and more efficient sewage treatment plant.

Benefits

• Unobtrusive below ground installation
• Suitability for varying invert levels
• 450 and 750mm invert options
• Excellent durability
• Low profile results in shallow depth excavation
• Simple maintenance with easy desludging
• Pumped discharge option available
• Compliant with BS EN-12566 Part 3
• Proven standards of discharge - 20mg/l BOD, 30mg/l S.S. and 10mg/l Ammonia in domestic applications

A new generation of sewage treatment plants for treating domestic sewage waste in a compact system of three separate stages within a ‘unitank’ design. The fluidised fixed-film biozone process provides an extremely robust means of reducing ammoniacal nitrogen.

Raw sewage flowing to the unit is received in the primary settlement zone. Gross solids settle to the bottom. The residual effluent (supernatant liquor) is displaced from the primary stage into the two-stage biozone.

Flow circulation in the biozone is generated by the effect of a fine bubble system. During several passes through the beds, the supernatant liquor is purified by naturally occurring micro organisms (biomass) that grow on the media. The liquid displaced to the outlet is treated, and known as final effluent.
