Powdered Activated Carbon

ProMinent Australia have supplied many Powdered Activated Carbon preparation and dosing packages. Our preference is always to supply package as constant transfer and vary the PAC solution strength in proportion to the flow signal.

For smaller systems we offer our locally designed and manufactured vacuum loader for unloading from 20 kg bags. For larger water supplies we offer with bulk bag unloaders, with crane and hoist (or suitable for fork lift loading) flexible conveyors and storage hoppers.

From the day hopper the PAC is metered into a wetting cone/eductor arrangement in proportion to the mains water milliamp flow signal and transferred direct to a low pressure injection point (max 1 bar). For higher pressure discharge points, the PAC solution is transferred to a pump suction dilution tank from where it is pumped via a Spectra progressive cavity pump to the injection point.

Dosages of 1 to 20 mg/L are typical for nominal taste and odor control, but PAC dosages can range between 1 to 100 mg/L depending on the type and concentrations of organic compounds present. Activated carbon is commonly used to adsorb natural organic compounds, taste and odor compounds, and synthetic organic chemicals in drinking water treatment.


It is a highly porous material and provides a large surface area to which contaminants can be adsorbed.

Another type available is suitable for loading with a fork and can be optioned with retractable springs to stretch the bag when it becomes lighter

For Bulk Bag:
A small intermediate hopper is located under the bulk bag loader and feeds the day hopper via a spiral conveyor. The bulk bag loader we offer has a crane for lifting the bags into position.
