Conveyor Screens — Headworks
Integrated screening, washing, and dewatering in a single compact unit — reducing screenings volume, odor, and disposal cost.
What is a Conveyor Screen?
Conveyor screens — also known as spiral screw screens — integrate screening, conveying, and dewatering into a single unit. Wastewater flows through a perforated cylindrical screen at the base of an inclined shaftless screw conveyor. Solids are captured by the screen, transported upward by the screw, washed of organics, and dewatered during transport — all in one continuous operation. The result is a reduced-volume screenings product that is cleaner, drier, and far easier to handle and dispose of than raw wet screenings.
Equipment We Represent
WTP Equipment — Conveyor Screen Model CS
- Cost-effective, stand-alone unit for packaged or in-channel applications
- Ideal for confined space installations and small to medium screening applications
- U-Trough configuration — constant diameter shaftless screw with bolted covers for maintenance access; standard for most applications
- O-Trough (high-capacity) configuration — circular housing with stainless steel flatbar wearliner; allows higher angle installation for reduced footprint and wider channel applications
- Shaftless screw design — no internal shafts or bearings to plug with stringy or fibrous materials
- Enclosed housing for odor control and operator safety
- Optional screenings washing stage
- Optional screenings bagger for contained disposal
DryCake — Perfobask Basket Screw-Screen
- Combined screening, washing, and compaction in a single in-channel or in-tank unit
- Screw conveyance transports and dewaters captured screenings
- Integrated compaction reduces screenings volume and disposal cost
Applications
Primary screening at municipal treatment plant influent channels
Compact screening in confined wet well environments
Screening of digester supernatant and cleanout flows
Removal of solids from hauled septage and grease trap waste
Why Winschel Environmental?
- All-in-one solution — screen, convey, wash, and dewater in a single unit with a small footprint
- Reduced disposal costs — drier, cleaner screenings mean lower hauling and landfill costs
- Shaftless design advantage — handles the stringy rags and fibrous materials that jam shafted systems
- Two trough options — U-trough for standard applications, O-trough for higher-capacity or tighter installations
- Virginia coverage — local support for startup and service
