Dilution means reducing the concentration of solute in a solution by simply adding more solvent. This dilution step guarantees a perfect solid-liquid ratio in the feed to enhance the settling rate once flocculants are added. Flocculants are more effective if added to a perfect solid-liquid ratio.
ANDRITZ dilution system GR is an internal dilution system used for thickeners, and located inside the tank, at a distance that will not hinder free settling rate or mud bed formation. This system can handle flow rate from 0 to 2,600 m3/hr (adjustable flow rate) and is easy to retrofit.
