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 by volume and in a reproducible manner 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 into the wetting cone at the same time as the treatment water. The PAC suspension is supplied to the metering point at a max. back pressure of 1 bar via the Venturi water ejector.
