Reduce energy use and footprint
The Hydro MicroScreen™ is a low-energy, small-footprint system, providing economical treatment in a small space. With a footprint of between 4 and 10 m2 (43 and 107 sq ft) and an energy demand of between 2.5 and 7.0 hp. It saves up to 50% on energy use and up to 90% on footprint compared to conventional primary treatment technologies.
Cut maintenance costs and system downtime
Maintenance of a conventional primary clarifier is a costly, lengthy and hazardous process. By contrast the Hydro MicroScreen™ is a small and accessible unit that can be cleaned and maintained quickly and easily – minimizing maintenance costs and reducing costly system downtime. A two-unit system provides dual redundancy, eliminating system downtime during maintenance altogether. By reducing the load placed on downstream systems and processes it also prolongs downstream equipment lifetimes and reduces the downstream maintenance burden.
Turn waste into a commodity
Hydro MicroScreen™ screens and captures industrial process material and by-products at high removal rates. This captured material may then either be returned to the process chain, cutting waste and increasing operational efficiency, or used to offset costs by converting it into energy or selling it on to secondary markets.
Save on solids handling
With dewatering section and compression zone, Hydro MicroScreen™ produces up to 50% total solids without the use of chemicals. This increases the efficiency of solids handling, cutting the cost of transport and disposal.
Protect downstream treatment systems
The Hydro MicroScreen™ does not require equalization prior to screening, and will reduce the TSS and particulate BOD going into a Dissolved Air Flotation (DAF) system - reducing the load to help achieve better overall performance. In a new DAF installations a Hydro MicroScreen™ can reduce the size / capacity of the DAF system required.
Capture more solids
Wedgewire drum screens are typically offered in sizes that range from 250 – 1500 micron openings. This means they will miss the materials that are smaller than that. The Hydro MicroScreen™ can be sized to capture particles as small as 100 micron and larger. Finer solids are the most difficult to deal with and can contribute to a large portion of the total solids loading.
Additionally, drum screens require a separate compaction / dewatering system. Compared to drum screens, the Hydro MicroScreen™ provides significantly better performance in TSS and BOD removal, uses less wash water, and does not require a separate compaction system.
Cut your sedimentation / clarification footprint
In addition to materials recovery and solids removal, the Hydro MicroScreen™ offers numerous benefits compared to conventional settling / sedimentation systems:
- Uses just 15-30% of the energy
- Provides superior solids dewatering
- Reduces overall solids handling costs
- Requires as little as 10% of the overall footprint
- Reduces retention time
- Increases plant capacity
- Often does not require chemicals
- Capital construction costs are just 20-30% of a conventional settling system
