How Powdered Activated Carbon (PAC) works

Taste & Odour

Activated carbon is wideley used in the drinking water treatment proces for the removal of taste and odour. In some instances, granular activated carbon (GAC) beds are used, however, these are huge CAPEX projects. Further to this, the OPEX remains very high, as the GAC requires regenetation at regular intervals. Our range of dosing solutions offer a clean, efficient and flexible interface for handling PAC. Taste and odour problems are often seasonal, and sometime relativeley short-lived. Our TransPAC solutions can easily be moved from site to site, giving you a fast and effective tool to deal with these seasonal issues, without the burden of large, slow and costly remedial projects.

Pesticide Removal

Metaldehyde is a selective pesticide used by farmers and gardeners to control slugs and snails in a wide variety of crops. It is sold under a variety of brand names, generally as blue coloured pellets.
In certain locations Water companies have recently been detecting traces of metaldehyde in the water they extract from rivers and reservoirs which, although are at low levels, are above the European and UK standards set for drinking water. Unfortunately some current treatment methods designed to remove a range of pesticides are not effective at reducing the levels of Metaldehyde in water.
Granular Activated Carbon (GAC) and Powdered Activated Carbon (PAC) are commonly used in the water treatment process to remove pesticides. However, due to the characteristics of Metaldehyde, the life of Granular Activated Carbon (GAC) is significantly reduced, thus increasing the GAC regeneration frequency which, in turn, increases treatment costs and plant shut-downs. Powdered Activated carbon does not have these operational problems and can be used to remove Metaldehyde. Find out more about how a TransPAC can tackle Metaldehyde

Algae Bloom

Algal blooms occur when the nutrients getting into surface waters cause rapid growth in the algae present in the water. It has caused sporadic problems in water treatment processes for decades. When water abstracted for drinking water treatment contains algal blooms, blockages can occur in filters and odours may develop in the treated water.
A simple solution to control Algae bloom is adding required levels of powdered carbon (PAC) to the water. Transvac offers a range of dosing solutions, including the containerised TransPAC system.
