Micro Bar Screen for Irish Local Authority Wastewater Treatment Plants
Reliable Ultra-Fine Screening at Headworks
The Or-Tec Micro Bar Screen is a high-performance mechanical bar screen specifically designed to meet the demands of Irish Local Authority wastewater treatment plants.
Installed at the headworks, the Micro Bar Screen provides ultra-fine screening down to 1 mm, effectively removing wipes, rags, hair, plastics and stringy debris before they reach downstream processes. This significantly reduces blockages, ragging, and unplanned maintenance across the treatment works.
Designed for Irish Local Authority Challenges
Irish wastewater treatment plants face increasing pressure from:
- Wet wipes and non-flushable materials
- Variable flows during storm events
- Rising maintenance and operational costs
The Micro Bar Screen is engineered to operate reliably under these conditions, helping Local Authorities improve resilience, compliance, and operational efficiency.
How the Micro Bar Screen Works
Ultra-Fine Mechanical Screening
Wastewater passes through precision-engineered tapered bars, capturing solids as small as 1 mm without excessive headloss.
Self-Cleaning Rake System
A continuously operating rake removes captured material from the bars, preventing clogging and maintaining consistent screening performance.
Continuous, Low-Maintenance Operation
The design eliminates the need for wash water, brushes, or complex cleaning systems, keeping maintenance requirements low.
Key Benefits for Local Authorities
- Ultra-fine screening down to 1 mm
- Excellent capture of wipes and fibrous material
- Non-clog tapered bar design
- Low headloss across the screen
- Reduced ragging in pumps and downstream equipment
- Lower maintenance and operational costs
- These benefits make the Micro Bar Screen a proven solution for modern Irish wastewater treatment plants.
Proven Performance in Local Authority
The Micro Bar Screen has been installed in hundreds of municipal and local authority wastewater treatment plants worldwide, delivering reliable fine screening where traditional bar screens struggle.
For Irish Local Authorities, this means:
- Improved protection of pumps and biological processes
- Reduced emergency callouts
- More stable treatment performance
- Longer equipment lifespan
Installation & Integration
Flexible Installation Options
- In-channel installations
- Retrofit into existing headworks
- New wastewater treatment plant designs
Compact Footprint
The Micro Bar Screen’s compact design makes it ideal where space is limited—particularly in upgraded or constrained Irish treatment works.
