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 NT is an internal dilution system, which means that the entire system is located inside a thickener tank and makes use of internal overflow liquor for dilution purposes. Ideal for flow rate between 600 and 9,000 m3/hr, ANDRITZ dilution system NT uses overflow liquid to dilute incoming slurry to the required solid-liquid ratio and can accommodate slurries with low pH values.
