Clarification

Segmented Plow Rake
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. Learn More about this product.

In addition to providing support, the pier resists the torque developed by the collector's sludge plowing action. Learn More about this product.

Suction Header Clarifier
An alternate to the SightWell method of rapid sludge removal is the Walker Process MultiDraw, a multiple suction nozzle-type collector. The MultiDraw can be furnished in either bridge-supported (Type "SC") or pier-supported (Type "RSM") designs. Sludge suction pipe arms, V-plows and a manifold assembly enable sludge to be "vacuumed" off the tank floor over the full length of each pipe arm. Learn More about this product.

Suction Pipe Clarifier
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.

Rectangular Collectors
Rectangular Collectors are conventional chain and flight collectors for use in rectangular sedimentation basins. Walker Process Equipment furnishes a full line of designs including malleable iron or plastic chain. Depending upon the particular application, collectors can be provided with accessory items such as surface skimmers (rotating pipe, chain and flight or helical), cross collectors (chain and flight, helical), or telescoping valves.

Clarifier Drive Units
Walker Process Equipment Spur Gear drives are precision Class 6 gear assemblies (after heat treatment) and include a split spur gear ring that allows access to replaceable bearing race inserts. Walker Process Equipment worm gear drives for bridge supported collectors consist of a single piece alloy steel worm and worm shaft matched to a centrifugally cast manganese bronze or cast iron worm gear and housed in a precisely machined, high grade, cast iron housing. The drives are simple, rugged, and provide extra long life with minimal maintenance. Learn More about this product.
