For the investment project "Kalová koncovka“ (Sludge Terminal) at the Handlová WWTP we supplied butterfly valves and knife gate valves operated by electric actuator.
The investment project is focused on solving the management of sludge produced on the line of mechanical and biological wastewater treatment. The produced sludge is newly first aerobically stabilized in mechanically and pneumatically aerated tanks and then mechanically dewatered on a new machine dewatering line. The dewatered sludge is transported directly to a covered sludge dump. Sludge water from stabilization tanks and mechanical drainage is returned to the biological part of the WWTP.
The supplied knife sgate valves are used to drain the sludge, but also to return the sludge water. Butterfly valves are installed in the sludge aeration lines behind the blowers.
