Modular design with filtration grades from 20 to 400 µm, offering scalability and flexibility.
Combines screen and depth filtration for high contaminant removal rates.
Air-assisted backwashing with rinse water consumption at only 0.5% of filtrate capacity.
No consumables, resulting in low running costs and minimal maintenance.
Corrosion-resistant polypropylene pipework.

Options

Filtration grades available: 20, 50, 100, 130, 200, 400 µm.
Backwashing options include air-aided flushing (standard), internal or external flushing.
Piping options: plastic-coated steel, stainless steel.

Applications

Side stream filtration of cooling tower water.
Pre-treatment for softeners, ion exchangers, or membrane systems.
Feed water for irrigation systems.
Prevention of corrosion and blockages in pipework, valves, distributors, and other equipment.
Municipal wastewater treatment.
Aquaculture.
