Hubert micro screen
Efficient 50-micron pre-filtration for extended membrane life.
The Hubert micro screen is a robust and reliable screen with a mesh size of 50 microns. Specially developed as a pre-filtration stage in membrane filtration processes, it prevents fouling and significantly extends the service life of nanofiltration and reverse osmosis membranes.
Features
The micro screen removes fine particles from the effluent of biological treatment, drastically reducing the load on downstream membranes. Even at high turbidity levels, for example during sludge flushing, the micro screen delivers stable effluent quality, minimises peak loads, and prevents clogging of sensitive filtration systems.
The micro screen can be used as a pre-filtration step in:
- Pilot and test rigs
- Nanofiltration or reverse osmosis
- Tertiary treatment of WWTP effluent
- Industrial wastewater treatment
- Water reuse systems
Tests on biological effluent show that:
- Pressure drop across the membrane is significantly reduced
- Cleaning frequency decreases from every 2-3 days to every 2 weeks
- Efficiency is maintained even at turbidity levels up to 60 NTU
For maximum performance, the microscreen can be combined with:
- Automatic monitoring & control
- Ultrasonic cleaning
- Finer mesh variant (10 µm)
Advantages
- Extended membrane service life - Up to 5x fewer chemical cleaning cycles required
- High separation efficiency - 50 micron filtration reduces peaks in sludge loading
- Stable filtration performance - Fewer fluctuations and blockages
- Robust design - Low-maintenance and suitable for industrial environments
- Upgradeable - Optional 10 micron mesh and ultrasonic cleaning available
