Saveco : The BEAST
Next generation VFA septage receiving stations
Septage Receiving Stations are not only used for septage treatment but also for Fats, Oils and Greases (FOG) - when high temperature washwater is used. The station screens, washes, conveys, and dewaters screenings all in one unit, thus eliminating the need for multiple pieces of equipment.
It consists of a dual motor drive system, a perforated plate drum screen complete with screw conveyor, and a compaction zone, all installed in a tank.
CASE STUDY: A local Council simplified its waste management, reducing network damage and maintenance and installation costs with New Zealand's first BEAST Septage Receival Screen. Read more here.
