Tomal® metering system for powdered activated carbon (PAC)


Tomal® metering system for powdered activated carbon (PAC)

Effective elimination of micro-contaminants as the last stage of waste water treatment – efficient, precise and reproducible 5-50 kg/h of dry PAC with a re-dilution of 3-5 m3/h and a final concentration of max. 1%

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 with repeatability and 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.

Features & Benefits

  • Economical thanks to volumetric metering – no over-metering
  • Maximum reproducibility
  • Dust-free metering
  • Better than 1% precision
