Background

This plant is a leading paint manufacturer in Poland and is known worldwide. This high-density chemical sludge with a very high inorganic content (>90%) makes dewatering difficult, if not impossible, for conventional screw presses. With the VOLUTE DUO™ and its special twin screw design, AMCON can dewater even this high inorganic sludge and offer this client all the other benefits of a screw press.

Installation details

The VOLUTE DUO™ RVP-241 dewatered 30 m3 of sludge in 24-hour non-stop operation with a throughput of 41 kg-DS/h and a cake dryness of 56.9%. During operation, coagulation and flocculation were carried out by the in-line mixer to achieve the best quality flocs.
With its small footprint, very good cake dryness, filtrate quality, and low energy consumption, the VOLUTE DUO™ can now be used in this type of industry where conventional screw presses encounter many challenges.
