CST KDS separator

CST has released a clog-free, automatic liquid-to-solid waste separator that is suitable for compact dewatering applications ranging from food processing, food waste, grease trap and waste oil through to municipal wastewater sludge, livestock manure and agribusiness processes.

The compact KDS multidisc roller separator features a self-cleaning dewatering and conveying system with oval plate separation and transfer structure that prevents clogging and permits automatic continuous operation that handles oily and fibrous material with ease. Designed for efficiency, sustainability and conservation of resources in small to medium applications, the energy-efficient separator consumes as little as 0.06 kWh of electricity and uses washwaster.

The simple-to-maintain separator offers a high throughput within a small body, with the smallest model being just under 350 mm wide and weighing 50 kg. The compact rotational oval plate structure achieves high transportation and separation efficiencies, while the simplicity of the machine’s overall structure offers low maintenance.

The KDS separator uses a fraction of the power of a centrifuge, according to the company, and has no water usage during operation, unlike a belt press or a screw press. It offers a high-performance alternative to sludge drying beds and geobags.

Used for thickening of dissolved air flotation sludge, the separator achieves solids capture of 97% thickened sludge at a dryness of 17%. Waste-activated sludge dryness levels are typically 15–25%, according to the company.
