Noggerath® Centre-Flo™ Band Screen
Coarse and fine screening of municipal fresh water, sea water, sewage and industrial wastewater; fully customizable and highly efficient machine to improve and protect downstream treatment processes.
- The diverter plates direct the influent flow into the submerged section of the screen. The flow then undergoes a 90° change in direction to flow through the Centre-Flo™ screen panels. The screen panels retain the solids and allow the screened effluent to pass through to the subsequent treatment processes. Centre-Flo’s are typically controlled based on upstream water level or differential level allowing the band screen to remain stationary allowing solids to build up on the screening elements. This helps the screen to capture finer particles, further increasing capture efficiency.
- While in this stationary mode, the head loss across the screening element increases, causing the upstream water level to rise. Once the upstream water level or differential level reaches a pre-set high, the screen will automatically enter a cleaning cycle.
- During the cleaning cycle, the band screen will rotate, lifting the collected solids and dropping them into the discharge flume. The finer solids captured on the screen panels are flushed off the screen using the wash sparge system located on the opposite side of the screen. The cleaning cycle will typically run through a complete revolution of the band screen, effectively cleaning the entire screen. During the cleaning cycle the upstream water level will continue to drop until the screen is completely cleaned and normal operating levels are reached.
- Highest screenings capture rate technology on market due to efficient flow path and panel media. (up to 85%)
- Best hydraulic performance on market with our full bore perforated panel or patented honeycomb panel.
- Able to handle influent with a high grit and gravel loads
- Low maintenance with virtually no wearing parts and no requirement for channel access.
- Effective organics washing and recycling of the screened solids.
- Improvement of downstream processes provides operational and maintenance efficiencies.
- Excellent retrofitting capability to existing channels to improve plant hydraulics and screenings capture efficiency e.g. coarse screen or step screen replacement.
- Can be designed to accommodate channel dimensions and hydraulic requirements; highly suitable for deep channel designs.
- Sea water and municipal fresh water
- Conventional wastewater treatment processes
- Final pre-screening for Membrane Bioreactor (MBR) processes
- Industrial wastewater applications
