CST Wastewater Solutions KDS Multidisc Roller system

The KDS Multidisc Roller system from CST Wastewater Solutions is a compact and cost-efficient alternative to conventional sludge dewatering technologies. The system is engineered to overcome the limitations of technologies such as screw presses, belt presses and centrifuges.

KDS technology incorporates automatic liquid-to-solid waste separation that removes more than 50% of the water from wastewater sludge to provide a 50% reduction in transportation costs.

Used for thickening dissolved air flotation sludge — a common application throughout wastewater operations — the system achieves solids capture of 97% thickened sludge at a dryness of 17%.

The Japanese-manufactured technology uses minimal energy, consuming as little as 0.06 kWh of electricity; operates at low (63 dBa) non-intrusive noise and vibration levels; requires minimal daily maintenance, saving cost and enhancing OHS performance; and typically occupies half the space or less of conventional dewatering plants.

The lighter, dryer waste reduces the need for manual labour in cleaning and transport operations and curtails the need for staff to handle sloppy heavy waste potentially hazardous to health.

The self-cleaning dewatering and conveying system features an oval plate separation and transfer structure that prevents clogging and permits automatic continuous operation that handles oily and fibrous material with ease.
