Rotary Drum Screen RSI for solid-liquid separation, transportation, dewatering, and compression.
It also handles oily and adhesive drainage and wastewater treatment. It can be installed directly in the waterway (or connected via piping) and transports the collected solids using a spiral conveyor.
The "Rotary Drum Screen RSI" is a product that performs precise filtration of wastewater in waterways, tanks, and basins using wedge wire, punching, and wire mesh screens. The solids accumulated on the screen after filtration are automatically transported, dewatered, compressed, and discharged. In contrast to the common technology that drives the screen via a discharge spiral conveyor, the driving energy acts directly on the drum. It can be customized to the minimum overall height according to installation space requirements, making maintenance of the drive unit easier. 【Features】 ■ No need for a center/drive shaft in the spiral conveyor ■ Capable of transporting relatively large particle sizes ■ The spiral opens in both the transport direction and axial direction during discharge, preventing clogging ■ Easy access to the compression zone ■ Compression zone equipped with a pressure flap 【Examples of Applications】 ■ Food ■ Meat processing ■ Paper and pulp ■ Aquaculture ■ Livestock ■ Chemicals ■ Sewage treatment, sludge ■ Waste ■ Pretreatment for MBR (Membrane Bioreactor) *For more details, please refer to the PDF document or feel free to contact us.
