WTP Equipment Corp
About
WTP Equipment Corp has manufactured mechanical wastewater treatment equipment since 1997, specializing in headworks screening, grit removal, clarification, and solids handling for municipal and industrial treatment plants. The company takes an engineered systems approach, customizing each installation to meet specific plant capacity, channel geometry, and operational requirements. Their screening lineup includes mechanically cleaned reciprocating bar screens with submerged-rake-only design to prevent drive fouling, deep well bar screens for vertical pumping station applications with anti-fouling discharge configurations, continuously cleaned fine screens with belt filtration media, and conveyor screens available with heat-tracing for cold-climate installations. Grit management products span vortex grit removal chambers in both cast-in-place concrete and prefabricated packaged configurations, cyclone-type grit classifiers with optional concentrators, and shafted and shaftless screw grit collectors including aerated and inclined variants. For solids handling, WTP offers screenings washing and dewatering presses using shaftless screw design for volume reduction and odor control, along with shaftless screw conveyors that eliminate internal bearings to prevent wrapping and plugging. Clarification equipment includes rectangular clarifiers with chain-and-flight mechanisms and scum trough assemblies for secondary treatment. WTP Equipment Corp holds memberships in WEFTEC, OPCEA, and WEAO, and serves the Canadian market through partnership with Environmental Inc.
Key Products
Front-cleaned, front-return bar screen with stationary rake-cleaned rack design where only the rake moves while submerged, eliminating drive system fouling at wastewater treatment headworks.
Heavy-duty reciprocating bar screen designed for vertical lifting in deep wastewater pumping stations, featuring anti-fouling discharge design for reliable solids removal in confined vertical shafts.
Continuously cleaned self-unloading belt screen with two-dimensional grid and projecting teeth for fine solids capture downstream of coarse bar screens.
In-channel or packaged conveyor-type screen for confined space installations, available with heat-tracing capability for cold-climate operation.
Vortex-induced grit separation chamber available in cast-in-place concrete or prefabricated packaged configurations, using air-lift pumps or recessed impellers to concentrate and remove inorganic grit.
Shafted or shaftless screw classifier with optional cyclone concentrator that washes and dewaters grit separated from the wastewater flow, recovering clean inorganic material for disposal.
Horizontal screw collector with central shaft for transporting settled grit across the floor of aerated grit chambers to a discharge point.
Shaftless spiral screw collector for aerated grit tanks, eliminating internal bearings and shaft to reduce maintenance and plugging from grit and debris.
Grit collection system with aeration to maintain organic material in suspension while allowing denser inorganic grit to settle for screw conveyor removal.
Inclined screw grit collector that transports settled grit upward from the collection point to an elevated discharge, integrating collection and removal in one unit.
Shaftless screw press that conveys, washes fecal matter from, and dewaters captured screenings to reduce volume, weight, and odor before landfill disposal.
Enclosed shaftless screw conveyor without internal bearings for transporting wet, coarse, or sticky materials including wastewater screenings, sludge, and food processing waste.
Rectangular sedimentation basin for secondary clarification of activated sludge mixed liquor, with mechanisms for sludge collection and scum removal.
Chain-driven flight collector mechanism for rectangular clarifiers that continuously sweeps settled sludge to a hopper and floated scum to a removal point.
Surface skimmer trough assembly for collecting and removing floating scum and grease from clarifier surfaces in secondary wastewater treatment.
