A quality ratio for screenings washing is defined as the mass of BOD or COD that can still be leached from the washed screenings per the dry solids mass in the screening.
In this white paper from Huber Technology, Dr. Roediger Consult from Stuttgart, Germany, examines a leaching method and discusses its results. You'll examine conventional wash-presses, super-launder wash-presses and the quality of washed screenings. The included chart shows a comparison of screenings quality.
