Оn January 2021 a sludge dewatering system was launched in Phoenix, AZ, at one of the largest breweries in the USA. This system is designed for around-the-clock operation and includes one multi-disk screw press MDQ-404 C and three shaftless screw conveyors.
MDQ-404 C Screw Press dewaters aerobically stabilized DAF-thickened MBBR sludge at a capacity of 70 gpm with 2–4% DS content. Dewatered sludge is then discharged into two parallel dumpsters through the system of three – one feed and two distribution – conveyors. The feed conveyor receives cake from the MDQ screw press and transports it to one of two distributing conveyors depending on cake level in the dumpsters. Each distributing conveyor discharges cake to a separate dumpster through two discharge spouts each equipped with an ultrasonic level sensor for cake level measurement. This allows to evenly fill the dumpsters with the dewatered sludge.
