Last updated: Aug 03, 2026
What is the Or-Tec Screw Screen Compactor?
Or-Tec Screw Screen Compactor for Municipal & Industrial Wastewater Screening
The Or-Tec Screw Screen Compactor is a mechanical wastewater screening system that screens, washes, compacts, and conveys screenings in a single unit. Designed for municipal wastewater treatment plants, food processing facilities, paper mills, and industrial wastewater applications, it removes solids while reducing screenings volume for easier handling and disposal. The system is available for in-channel, vertical, and in-tank installations with 2-6 mm perforated screens for municipal wastewater. For industrial applications, 0.25-2 mm wedgewire and 2-6 mm perforated screens.
Integrated wastewater screening system: The Or-Tec Screw Screen Compactor is a mechanical wastewater screen that screens, washes, compacts, and lifts screenings to a convenient discharge height for disposal.
Multiple processes in one unit: It combines multiple screening processes into one compact system, reducing screenings volume while simplifying disposal.
Designed for demanding applications: The system is designed for municipal wastewater treatment plants, food processing facilities, paper mills, and industrial wastewater applications where reliable solids removal and low maintenance are important.
How can I reduce the volume of wastewater screenings before disposal?
Integrated screening and compaction: The Or-Tec Screw Screen Compactor is designed to screen, wash, compact, and convey screenings within one integrated machine, helping reduce screenings volume before disposal.
Cleaner screenings: A wash station is standard in the compaction zone, with optional wash stations available in the screening and conveying zones to further clean screenings.
Lower handling and disposal costs: By reducing screenings volume and preparing material for disposal, the system helps simplify screenings handling and can reduce transportation and disposal requirements.
How can I stop rags and wipes from wrapping around our wastewater screening equipment?
Shaftless screw technology: The Or-Tec Screw Screen Compactor uses a shaftless screw auger that helps prevent rags, wipes, ropes, hair, and other stringy debris from wrapping around the screw.
Reduced maintenance: Unlike conventional shafted screw conveyors, the shaftless design minimizes material buildup, helping reduce maintenance and improve reliability in high-solids wastewater applications.
Reliable solids handling: The system is designed to provide dependable screening performance for municipal wastewater treatment plants, food processing facilities, paper mills, and industrial wastewater applications.

Can one machine screen, wash, compact, and convey wastewater screenings?
Four processes in one system: Yes. The Or-Tec Screw Screen Compactor combines screening, washing, compaction, and conveying into one compact, automated system.
Simplified installation: By integrating multiple screening processes into a single unit, the system can reduce equipment requirements, simplify installation, and minimize the need for additional solids handling equipment.
Flexible installation options: The Screw Screen Compactor is available in in-channel, vertical, and in-tank configurations to accommodate a wide variety of municipal and industrial wastewater treatment applications.
How does the Or-Tec Screw Screen Compactor handle rags and stringy materials?
Very well, the Or-Tec Screw Screen Compactor uses a shaftless screw auger, helping prevent rags, wipes, ropes, hair, and other stringy debris from wrapping around the screw.
Unlike conventional shafted screw conveyors, the shaftless design minimizes material buildup, reduces maintenance, and improves reliability in high-solids wastewater applications.
What Or-Tec Screw Screen Compactor screen opening sizes are available?
Application-specific screening options: The Or-Tec Screw Screen Compactor is available with different screening media depending on the application.
Municipal wastewater: For municipal wastewater, perforated screens are available from 2 mm to 6 mm.
Industrial wastewater: For industrial wastewater, wedgewire screens are available from 0.25 mm to 2 mm, and 2-6 mm perforated screens, allowing finer solids removal for demanding industrial processes.
Does the Or-Tec Screw Screen Compactor wash and compact screenings?
Integrated screening and compaction: Yes. The Or-Tec Screw Screen Compactor is designed to screen, wash, compact, and convey screenings within one integrated machine.
Enhanced screenings cleaning: A wash station is standard in the compaction zone, while optional wash stations can also be installed in the screening and conveying zones to further clean screenings before disposal.
What is the difference between the Or-Tec Screw Screen Compactor and a mechanical bar screen?
The Or-Tec Screw Screen Compactor not only removes solids from wastewater, but also washes, compacts, and conveys the captured screenings for easier handling and disposal.
A conventional mechanical bar screen typically performs only the screening function and requires separate equipment for conveying or compacting screenings. By combining multiple processes into one machine, the Or-Tec Screw Screen Compactor can reduce equipment requirements and simplify installation.
Where can the Or-Tec Screw Screen Compactor be installed?
Available in several configurations to suit different plant layouts and retrofit projects.
Available models include:
- OSC - In-channel installation
- OSC-V - Vertical installation
- OSC-T - In-tank installation
- OHS - High solids applications
- ORD-C - Rotating drum channel model
- ORD-T - Rotating drum tank model
These installation options provide flexibility for municipal wastewater plants, industrial facilities, and OEM wastewater treatment systems.
What wastewater applications is the Or-Tec Screw Screen Compactor designed for?
Typical applications include:
- Municipal wastewater treatment plant headworks
- Food processing and packaging
- Paper mills
- Industrial manufacturing
- OEM wastewater treatment systems
Its combination of screening, washing, compaction, and conveying makes it suitable wherever screenings must be removed and prepared for efficient disposal.
Why do wastewater treatment plants choose the Or-Tec Screw Screen Compactor?
All-in-one screenings handling: Many wastewater treatment facilities choose the Or-Tec Screw Screen Compactor because it combines screening, washing, compaction, and conveying into one compact, automated system.
Reliable, low-maintenance operation: Its shaftless screw design, self-cleaning screen, stainless steel construction, multiple installation configurations, and optional heat tracing and insulation help provide dependable operation while reducing maintenance requirements.
