CSO Group : Pump Action Screen (PAS)
The Pump Action Screen (PAS) is a revolutionary concept in mechanical screenings.
The PAS screen is designed for screening storm water in various applications. The screen will retain all gross solids larger than 6mm in two directions, in the pass forward flow for removal downstream.
Key features include:
- 6mm screening in two directions
- High Solids Retention Value (SRV) of 58%
- Robust proven components with no moving parts
- Minimal maintenance with servicing able to be carried out without man entry into the chamber
- Modular system for retrofitting through existing manholes
- Scour system reduces screenings presented to the scree, giving improved screening efficiency
- Introduction of air reduces oxygen demand of the spill and pass forward flow
- Can be installed in both deep and shallow chambers without effecting performance
- Low power requirements
Applications
- CSO's
- Storm Water Retention Tanks
Flows
- Can screen flows up to 1766l/s as a single screen
- For larger flows, multiple screens can be installed in parallel
Materials
- Stainless steel construction (304 & 316)
Models
- Available in 300mm and 500mm diameter screen baskets
