The Klargester 750mm invert BA BioDisc sewage treatment plant with integral pumped outlet, alarm beacon and control panel. Central to the treatment process is the rotating biological contactor (biodisc), which supports a biologically active film or biomass on to which aerobic micro-organisms, naturally found in sewage become established. The BA BioDisc will suit one property up to 4 bedrooms. Firstly Wastewater and sewage flows into the primary settlement chamber, where solids are settled and retained. Partially clarified liquor containing fine suspended solids flows upwards into the first stage biozone for breaking down by micro-organisms. Suspended solids return to the primary settlement chamber and the liquor to the second stage biozone for further treatment. All remaining solids are settled out in the final settlement tank, the treated effluent is then discharged via the outlet pump. Manufactured by Kingspan from glass reinforced plastic (GRP) and certified to EN 12566 - building regulation compliantOverall dimensions: 1995 diameter x 2150mm high.
