product description

The apparatus consists of a filter material silo and a solids metering device with mechanically and hydraulically coordinated components for metering solids (e.g. shell limestone) into the water flow. The covered hopper is connected to the rotary valve feeder under a silo. The solid is pumped by means of a jet pump. The cover is equipped with a monitoring opening. A purging device ensures the solid is completely discharged.
