Effective elimination of micro-contaminants as the last stage of waste water treatment – efficient, precise and reproducible
The special metering system consists of the Tomal® Big Bag emptying unit, the powder storage tank and the Tomal® multi-screw feeder. This meters the powdered active carbon volumetrically and reproducibly with excellent precision. Unlike gravimetric metering systems, this technology requires no error-prone, maintenance-intensive weighing equipment.
Functional description:
The Big Bag is lifted into the carrier frame by a forklift. The outlet connection is released and it is fed into the powder funnel. The multi-screw feeder meters the PAC at the same time as the treatment water into the wetting cone. The PAC suspension is supplied to the metering point at a max. back pressure of 1 bar via the Venturi water ejector.
