Tech group ANDRITZ has unveiled OptiFLO, its new system for diluting thickener feed which is ideal for flow rates between 600 and 9,000 cubic meters per hour.

The new release uses overflow liquid from the thickener to dilute the incoming slurry/suspension to an optimum ratio of solids to liquids.

“The dilution system does not interfere with the thickener settling process and can also accommodate slurries with low pH values,” ANDRITZ explained. “And with different flow rate configurations available, each system can be adjusted flexibly to the individual customer’s needs.”

OptiFLO has been designed with interchangeable parts that do not require a shutdown of the thickener, offering easier maintenance, and the high-dilution flow rates can allow for lower power consumption and cost savings.

Additionally, ANDRITZ said, its new system can ben integrated into thickener automation processes.

“In the most challenging applications, reliable clarification and thickening are critical to maintaining continuous production. The dilution process, where liquid is added to the incoming material and the solids concentration is reduced by adding more solvent, is a critical step,” ANDRITZ said.

“Dilution guarantees a perfect solid-liquid ratio in the thickener feed, which in turn enhances the settling rate of particles in the suspension when flocculants are added.
