Green Filter™ Testing & Certification
Green Filter Polylok© Septic Tanks are designed to produce a higher final effluent quality to normal standard septic tanks. Green Filter Septic Tanks have the patented Polylok Filter fitted as standard.
By fitting this filter the Suspended Solids are reduced by up to 70% in the final effluent. This means there is a reduced probability of the land drain blocking preventing flooding and raw sewage floating to the surface.
The filter also produces a reduction in BOD this reduces smell and odours in the treated effluent. Units have been extensively tested to The EN12566-1:2005, the Pan European Standard. Marsh holds the certification for its entire range of Green Filter Tanks.
The units are available in 2800L,3800L,4500L & 6000L
