J+A Hi-FlowTM Screen

The highly efficient configurations of the J+A Hi-Flow™ screen exceed other screens on the market. The continuous band of screening panels are available in 2, 3, 5 or 6 mm perforations to accommodate a wide range of flows, water level and types of effluent. The total capture design has no carryover, and result in a 81% capture rate, with reduced overall headloss. A washwater system including internal rotating brushes remove solids and cleans the screen.
  • 2, 3, 5 and 6mm perforated screening
  • Single machine capacities of up to 3000 l / s (70 MGD)
  • Single pass screening with no carryover
  • Stainless steel construction
  • Vertical lift for small footprint

The J+A Hi-Flow™ screen is available in four screen sizes, with screen apertures of 2, 3, 5 or 6mm. A range of possible screen lengths are available so that each J+A Hi-Flow screen is tailored to meet individual requirements.

Primarily a screen will be selected for its peak duty points. Limitations are placed on the headloss at which the screen will operate, determined by the individual application’s hydraulic characteristics. It is important to select a screen relative to the range of flows, water levels, available channel space and the type of effluent to be screened.

  • High performance solids removal: 81.2% at 6mm (1/4”) perforation
  • Double screening area allows for higher flow rates and capacity
  • Reduced headloss satisfies existing channel requirements
