21st Century Water Screening Technology

Experts in Self-cleaning Water Intake Technology

Rotorflush Filters Ltd is a manufacturing Company specialising in the production and supply of automatic backwashing water screening products. Rotorflush is the brand name for our unique submersible pumps with integral self-cleaning intakes, and our wide range of suction intake filters and screens for use in dirty water.  Suitable for temporary or permanent installation.

Automatic Continuous Backwash

All our products incorporate automatic backwashing screens invented and supplied directly by Rotorflush, experts in liquid / solids separation who have been supplying the water-abstraction and water treatment industries for more than 20 years. 

Environmentally Responsible Production

Our stainless-steel, water-driven self-cleaning intake screens are built to operate 24 / 7 all year round in extreme water conditions, with minimal maintenance. Our all-steel screens, unlike polyurethane screens, cannot add microplastics into the intake stream, and all our screens are wholly recyclable.

Rotorflush Intake Screens - Applications and Use

Rotorflush self-cleaning intake screens are providing the benefits of low maintenance costs, higher uptime and ease of use to many sectors.

The UK Water Industry – 

Providing screened wash-water at waste water treatment works; screening at the point of water abstraction at water treatment works; automatic filtering and supply of sample water to analysers for water monitoring; eel screening at raw water intakes.

Agriculture – 

Simultaneous pumping and screening for farm dirty water systems; natural water screening and pumping for irrigation.

Industrial Use - 

Eel screening at raw water intakes; screening and filtration for cooling water, district heating systems and data centres. 

Real-World Development

Rotorflush self-cleaning screens were developed from the need to pump dairy farm run-off to irrigators to return dirty water to land. It quickly became apparent from demand for our products that the recurring issues of blocked pumps, blocked irrigation nozzles, and consequent maintenance and downtime are common to many industry sectors.

Protecting Equipment

Rotorflush self-cleaning intake screens and filters are now used in any application where there is a need to screen water as it is pumped or on intake by gravity to protect equipment further down the line, to meet environmental regulations and to pre-filter for further filtration. 

Water screening protection on intakes reduces maintenance costs by protecting equipment from blocking and clogging. Our screens are compact, maximising mesh open while constraining intake velocity, and offer high volume screening down to 1 mm through marine grade stainless steel mesh. A single central rotor is the only moving part, ensuring that our screens save on maintenance costs and increase productivity across all industries. 

Environment

BCorp Certification

As a BCorp certified company Rotorflush Filters Ltd takes its environmental responsibilities seriously and is pleased to be able to provide products that enable our customers to not only comply with current legislation and regulations for the protection of fish and eels but which by design protect aquatic life.  Our self-cleaning water intake screens are wholly recyclable at the end of their long lifespans.

Environmental Regulation Compliant

We work with our customers, consulting engineers and the Environment Agency to ensure that our screens meet the full requirements of a project.  We ensure our customer’s screens comply with environmental regulations concerning mesh sizes and intake velocities to minimise the impingement and entrainment of fish, fry, and elvers as required.
