Collect settled sludge and surface scum with scraper and suction arrangements matched to the sedimentation tank.
Flow slows in the sedimentation tank so suspended solids settle onto the tank floor.
Rotating arms or a travelling bridge move the scraper or suction equipment across the collection area.
Sludge moves to a central pit or suction outlet while the skimming arrangement collects floating material.
The selected drive and controls maintain rotation or reverse the travelling bridge for the next operating cycle.
Confirm the equipment arrangement and selected options against your process and installation requirements.
Choose peripheral-drive, central-drive, single-tube or travelling arrangements to match the basin and collection method.
The brochure describes mechanical scraping, pump-assisted suction and siphon discharge where suitable water-level conditions exist.
Travelling machines may use carbon steel above water and stainless steel below water; rubber, nylon or steel travel wheels are described.
Remote control and overload protection are described for selected families. Confirm the control and protection scope for the chosen machine.
Material compatibility and operating requirements determine the final equipment configuration.
