TRITAN - Belt Filter Press Solids Dewatering Technology - Brochure

Final dewatering occurs as the sludge is pressed between the primary seamless belt and a hollow perforated cylinder covered with a second belt. During this final step in the dewatering process, the discharged sludge cake reaches a solids concentration of 15 to 20%. Dewatering percentages vary based on sludge characteristics. A blade scrapes the sludge from the seamless belt and returns through a high pressure wash section to be cleaned before reaching the beginning of this continuous operation.
