Your challenges

We understand the common challenges you face in water treatment. Our filter and screening systems tackle these challenges head-on, safeguarding your processes and improving water quality.

Surface and wastewater often carry large debris

like leaves, plastics, and rags. These can clog pumps and damage downstream equipment.

Organic matter such as algae and plant waste raises the biochemical oxygen demand (BOD)

risking regulatory breaches and overloading treatment systems.

Fine particles, grease, and fibers build up on membranes and sensitive equipment

causing fouling, lowering efficiency, and increasing maintenance.

High energy consumption or process interruptions

from outdated or under-sized screening technology

How our filter and screening systems work

We offer a wide range of filter and screening solutions designed to remove solids based on size. Water flows through screens with specific openings — larger solids are caught, while smaller particles pass through. Our solutions can be divided into raw water intake / drinking water and wastewater treatment.

Raw water intake / drinking water:

  • Travelling basket (FlooScreen™): A mechanized system with automatic cleaning that lifts debris from water, ideal for treating intake water, large water level fluctuations, large volumes and coarse solids.
  • Drum basket (FlooScreen™): A rotary drum screen with a self-cleaning rotating drum and spray bars for continuous, energy-efficient and low-maintenance solids removal.
  • Automatic Bar Screen (FlooScreen™): A rugged, front-line mechanical screen designed to remove coarse solids from large flow streams and to ensure that larger objects do not get into the downstream process.
  • Sluice Gates (FlooScreen™): Elementary components in water canals and channels for stopping the water flow during operation, maintenance, service and repair work.
  • Fine sieve (IntenSieve®): Combines solids separation and thickening in one compact unit, replacing conventional primary treatment with greater efficiency.
  • Rotary drum screen (NTF): Features a patented water distribution system, perforated drum, and screw conveyor for efficient solids transport, especially for river and lake water.

Customer benefits

Our filter and screening systems deliver clear advantages:

Better water quality and compliance

Remove particulates and contaminants to meet discharge limits or improve potable water safety.

Protect critical equipment

Avoid damage and clogging in pumps, membranes, and pipes, cutting downtime and maintenance costs.

Boost treatment efficiency

Lower solids load before biological or chemical treatment stages to improve system performance and lifespan.
