Walker Process Equipment products

For greater flows and the resultant larger basins, higher torque capacities are required of the collector mechanism. A spur gear driven pier-supported collector is usually best applied in this class of service.  Walker Process Type RS collectors are built around a center pier which supports the entire rotating portion of the machine plus half of the access bridge load. In addition to providing support, the pier resists the torque developed by the collector`s sludge plowing action.

Suction header type mechanisms enable sludge to be "vacuumed" off the tank floor over the full length of each header.  Tapered Suction Type Clarifier Mechanisms, Type SCTP or RSMTP provide rapid sludge removal with a low profile header that is sized to provide a relatively constant velocity along the length of the header and with orfices space and sized to provide a flowrate proportional to the tank floor area served.

The Walker Process SightWell collector is designed to provide quick and uniform withdrawal of return and waste activated sludge from final settling tanks before the sludge becomes anaerobically degraded. Because modern plant designs incorporate high solids loadings in mixed liquor, rapid removal of oxygen-rich sludge is most important to ensure proper operation of the activated sludge process.
