How it works

Inlet

Wastewater enters the filter tank and passes through the cloth discs from outside to inside.

Filtration

The pile cloth media retains solids > 2 µm. The filtrate is discharged through the central hollow shaft.

Backwash

Automatic suction nozzles clean the filter cloth during operation without interruption.

Sludge discharge

The separated sludge is drawn off from the tank through a hopper.

Typical applications

Municipal treatment plants (tertiary filtration)Phosphorus removalIndustrial process water treatmentCOD/BOD polishingWater reuse

Filter media selection

Media type	Max. TSS loading (g/m²·h)	Typical max. TSS inlet (mg/L)	Phosphorus capability	Application focus
5 micron pile cloth	250	30	< 0.2 mg/L achievable	Advanced tertiary treatment & phosphorus reduction
10 micron pile cloth	700	70	Polishing stage (depends on conditions)	Higher solids load & general tertiary polishing

Performance depends on influent characteristics and effluent requirements. The decisive design input is the TSS load at the filter inlet.
