Tomal® metering system for powdered active 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
Overview
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.
