Rotork installs modular actuators at Chinese wastewater treatment plant

Rotork has installed more than 700 CK modular electric actuators at the Shantou wastewater treatment  in Guangdong, southern China facilities.

The actuators will allow carrying out sewage treatment in accordance with new environmental regulations.

Three new sewage treatment plants and 300 sewage intercepting wells will be constructed in Chaonan district, Shantou city.

Rotork installed the CK actuators on gate valves around the new sewage treatment facilities to control the flow of raw sewage in and out of the sewage interceptors.

The company said the actuators will separate contaminants from the wastewater to continue the purification process until it is safe to return into the environment. 100,000 tonnes of wastewater will be processed daily.

Rotork’s CK range of actuators, which are suitable for valves in the water industry, have a multi-turn output torque of up to 10,800 Nm.

The actuators’ modular nature allows them to be configured to meet the requirements of several applications. They can offer continuous valve position indication, even if there is no power.

Earlier this year, Rotork’s multi-turn electric actuators have been installed to control rainwater retention along a new road in Poland.

CK range actuators use power generated by solar panels and operate knife gate valves to control the emptying of rainwater storage tanks along the road in the central Polish city of Kalisz.
