Fish farm, France
This fish farm breeds trout. In order to save water, it operates exclusively with the RAS – Recirculating Aquaculture System. Until now, the sludge produced by the RAS separation by sedimentation was removed by tanker without any dewatering equipment, resulting in very high operating costs. When the site was renovated with the aim of reducing the volume of sludge and reusing the filtrates, the site decided to install a VOLUTE™ screw press.
After seeing a VOLUTE™ dewatering press at another fish farm, the customer decided to replicate the best practice and install a VOLUTE™ FS-132 unit. Thanks to the high efficiency of the VOLUTE™, we were able to achieve a minimum dryness of 30% at start-up. The maximum dryness of 35% is possible for this customer if they wish, knowing that the throughput would be reduced.
