Self-Cleaning Water Filtration

Clean water is the foundation of every well-functioning process. Whether it concerns industrial process water, surface water, wastewater or cooling water — water filtration ensures that solids, contaminants and suspended particles are removed before the water reaches further installations or is reused.

Self-Cleaning Water Filtration

Dutch Flow Control offers a wide range of self-cleaning water filtration solutions, tailored to varying contamination loads, flow rates and process conditions — we provide the right technology for every application, with self-cleaning filters ranging from 3 mm to 3 micron.

Self-Cleaning Water Filtration characteristics

Our self-cleaning filtration solutions are characterised by:

  • Always self-cleaning filters, enabling 24/7/365 operation — and also during emergencies when a separate power supply is available, for example a 1 kW generator or solar panels
  • Self-cleaning across multiple filtration stages in the range from 3 micron up to 3 mm (from MFF to ACF)
  • Compact installation with a large filter surface area; fibre technologies are applied to achieve a large filter surface within a compact footprint
  • Easy to expand when higher capacity is required, thanks to modular construction
  • Filtration without chemical cleaning, making it more environmentally friendly
  • Very wide range of applications, from industrial wastewater, recycling water for industrial cooling processes in the production process, mobile drinking water machines and mobile wastewater treatment plants, to replacing sand filters
  • Design and production in-house since 1993
  • Custom-built machines

Single Self-Cleaning Water Filtration

Single filter systems consist of one filtration mechanism and are suitable for applications where a specific filtration step is sufficient. They are straightforward to install, low in maintenance and cost-efficient.

The following products within our portfolio fall under single self-cleaning water filtration:

  • Screen bend — a static, gravity-driven self-cleaning screen with no moving parts, ideal for separating solids, with a filtration range of 0.25 to 2 mm
  • Drum filter (RDF) — a rotating self-cleaning filtration system for continuous separation of suspended and floating particles at high contamination loads, with a filtration range of 0.25 to 4 mm
  • ACF coarse filter — an automatic self-cleaning coarse filter for protecting pumps, pipework and other installations, with a filtration range of 0.1 to 5 mm
  • SCF self-cleaning filter — an automatic inline filter with intermittent backflushing on pressure differential, applied primarily as a self-cleaning filter for process water without process interruption. Filtration range from 15 micron to 3000 micron
  • HL-SCF — a variant of the SCF filter, specially suited for very high contamination concentrations, with continuous flushing ahead of the self-cleaning filter instead of intermittent flushing on pressure differential as with the SCF filter
  • MFF Microfilter — a multi-layer fibre filter system that is self-cleaning down to 0.5 micron, with most applications using the 3 micron filter

Combined Water Filtration

Combined self-cleaning filter systems bring together multiple filtration stages or techniques in a single integrated machine. They are developed for demanding processes where standard single filtration is insufficient:

  • The SCF and HL-SCF filters only have a built-in static non-self-cleaning coarse filter. When the SCF or HL-SCF filter is used in an outdoor installation with surface water and is not part of a closed system, a self-cleaning coarse filter becomes necessary. In this application, a self-cleaning ACF filter is combined with a self-cleaning (HL-)SCF filter
  • If finer filtration is then required without a sand filter or reverse osmosis RO filter being necessary, the MFF filter is added, creating the combination ACF + (HL-)SCF + MFF
  • Examples of combined self-cleaning filtration systems include the 50 micron system, the 3 micron system, the mobile wastewater treatment system, the mobile drinking water system and the replacement system for underperforming sand filters
