Twin screws dewatering press reduces the phosphorus level in the filtrate to 3 ppm
Background
The VOLUTE DUO™ dewatering press was installed at this facility to help the customer reduce the phosphorus content level to maximum 3ppm.
Our main objective was to verify the resistance to blockage against highly inorganic sludge.
Installation details
The VOLUTE DUO™ has provided satisfactory results.
The phosphorus level in the filtrate was maintained below the 3ppm limit while we reaching good sludge cake dryness.
