Pile Cloth Drum filter for municipal and industrial operations

The Pile Cloth Drum filter is a high-performance new-generation drum filter that uses the OUT-IN filtration principle, specially developed long-pile cloth, and the possibility of sedimentation in the filter tank. This combination enables extremely efficient removal of suspended solids and organic particles even under high hydraulic and solids loading, where conventional filters are less effective.

The Pile Cloth Drum filter is designed for operations requiring large filtration capacity, low energy demand, and maximum operational reliability.

It is the ideal solution for municipal wastewater treatment plants, industrial operations, and influent water filtration where emphasis is placed on treated water quality and stable operation.

Municipal wastewater treatment plants – the filter is suitable as a
- tertiary treatment stage – TSS removal, reduction of COD and BOD in the effluent, phosphorus reduction down to 0.1 mg/l. It is suitable for meeting strict discharge limits into receiving waters,
- quaternary treatment – use as pre-treatment for various PFAS removal technologies. The filter can be used in combination with powdered activated carbon dosing as a standalone quaternary stage.
- replacement of sand filtration – same or higher performance with dramatically lower energy and space requirements,
- filtration in areas with fluctuating hydraulic and solids loading – stable filter performance even during sudden increases in impurity concentration,
- optimization of existing WWTP operation – capacity increase without major civil works

Industrial operations – the filter is especially suitable for
- food and beverage industry
- textile and paper industry,
- power generation and heating industry
- aquaculture
- drinking water treatment plants

How does the Pile Cloth Drum filter work?

Untreated water including impurities flows into the filter tank in which the filter drum covered with filter cloth is located. The whole system is 100% submerged. Untreated water passes through the filter cloth and all impurities are captured on its surface (deep-bed sand filtration principle). As impurities are retained on the filter cloth, water flow through the filter decreases and the water level in the filter tank gradually rises. When the level probe is activated, the washing process is initiated and the drum begins to rotate. This process involves slow rotation and suction removal of impurities.

Once the water level drops to the set minimum, the wash cycle ends and the filtration cycle repeats. Treated water flows to the downstream technology.

Filtration goes on continually without interruption.
