Effluent Treatment Solutions
Lower-cost sludge dewatering for your ETP, CETP or STP.
Filtration is at the heart of effective effluent treatment. DFR filter press cloths deliver consistent performance, higher throughput and lower operating cost for sludge dewatering in industrial ETPs, common effluent treatment plants (CETPs) serving whole industrial estates, and STPs.

Three Problems
We Are Asked to Fix.
Cloth blinding on slimy sludge
How our cloth helps
Monofilament and calendered faces shed fine, gelatinous sludge instead of trapping it, so cycles stay fast and wash-downs are less frequent.
Wet sludge cake
How our cloth helps
Permeability matched to your polymer dose and sludge type gives a drier cake: lower disposal weight and handling cost.
Frequent replacement, high cost
How our cloth helps
Economical PP constructions with reinforced necks and edges, priced for the ETP budget and built to last more cycles between changes.
Filtration Application: ETP, CETP & STP Dewatering
Wastewater Collection
Effluent from the plant or the industrial estate.
Treatment Process
Chemical or biological treatment.
Sludge Thickening
Sludge is settled and thickened in the clarifier.
Sludge Press Dewatering
DFR cloth on the filter press separates water from sludge.
Dry Cake + Clear Filtrate
Cake to safe disposal; filtrate back to the plant.
- Maximum water separation
- Drier cake with lower disposal cost
- Stable operation and higher throughput
- Reduced chemical & energy consumption
- Longer cloth life and less downtime
