2 pcs of flocculation reactors FR1.7, before delivery to a waste water treatment plant in China
Flocculation of small sludge particles using the addition of polymers is a necessity for efficient sludge thickening and dewatering to take place.
By using flocculation reactors, which give residence times for flocculation to occur of 1-3 minutes during mixing, flocculation can occur completely before the polymer-sludge mixture enters the thickener/dewaterer.
The agitator is designed to eliminate possible ragging problems.
Siljan Allards supplies flocculation reactors, the capacities of which are selected to suit thickeners/dewaterers of different capacities; In the table below, the sizes and retention times of different models of flocculation reactors are shown.
