Tomal® metering system for powdered activated carbon (PAC)

5-50 kg/h of dry PAC with a re-dilution of 3-5 m3/h and a final concentration of max. 1%

Conventional waste water treatment cannot adequately remove trace elements, such as medication or cosmetic residue from the waste water. This is particularly effective using the complete system for the precise metering of powdered active carbon (PAC).

Product description

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.

Your benefits

  • Economical thanks to volumetric metering – no over-metering
  • Maximum reproducibility
  • Dust-free metering
  • Better than 1% precision
  • Tomal® metering system for powdered activated carbon (PAC)
