Sludge dewatering polymer dosage calculations
WebbThe sludge resulting from this process represents the next challenge for the water treatment industry, in particular the minimizing of its volume. This Sludge Dewatering … WebbThus, if the DS concentration in the de- watered sludge is 25 % or 30 % the disposal cost per ton DS can be calculated to vary between 880 and 2400 SEK/t DS (25 %), or between 700 and 2000 SEK/t DS (30 %). The polymer (120–140 SEK/t DS) and electri- city (12–60 SEK/t DS) used in the dewatering process are the other significant operational costs.
