High Volume Industrial Water Filters and Strainers

Rotorflush Filters Ltd manufacture and supply high volume self-cleaning filters and strainers that attach to the suction intake hose of surface mounted pumps.

What is a High-volume Intake filter?

Our high-volume filters and strainers are for screening large volumes of water in harsh and dirty conditions. They are excellent in conditions where basket strainers would normally block. This is because they contain an internal self-cleaning mechanism that backwashes the intake mesh whenever water is being drawn through the screen.

The filter mesh stays clean as a result of the effective self-cleaning large volume filter. This protects the intake screen from blocking as well as pumps, spray bars, irrigation nozzles and other equipment after the screen.

This means that you can filter dirty water on a pump suction hose or across a gravity feed, because a continuous backwash keeps the intake screen clear. So these high-volume industrial water filters operate in dirty water without the high maintenance associated with usual intake screening.

An easy to install strainer means that filtering and pumping and can be done simultaneously. And now our high-volume filters can move even more dirty water - our largest intake screens now handle up to 450 litres a second.

Large Volume filters for Fish and Eel Screening

The Environment Agency can place conditions on raw water abstraction licences in order to protect eels and other wildlife. Typically, this can be a constraint on the velocity of abstraction at a raw water intake and on the mesh size a used to screen the intake – usually 2 mm aperture or less.

Rotorflush filters fitted with 2 mm aperture mesh can comply with EA Eel regulations, the screens can be sized to ensure an intake velocity of no more than 0.1 metres / second for the flow rate you require.

Rotorflush filters have a low intake velocity by design. The gentle backwash maintains a clear filter mesh. This means that our self-cleaning low intake velocity large volume filters and strainers make ideal eel screens for raw water abstraction in both fresh water and seawater.

Rotorflush filters are Eel friendly – our products can help with your compliance with the Environment Agency’s Eel Recovery Plan (Council Regulation No.1100/2007) and The Eel Regulations which now apply in England and Wales.

So call for more information about using Rotorflush filters for eel screening.
