Tackling Metaldehyde issues with a TransPAC carbon dosing system

Activated carbon is widely used in the drinking water treatment process for the removal of taste and odour. 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.

Metaldehyde is a common slug pesticide, and difficult to get rid of

Powdered Activated Carbon (PAC) does not have these operational problems and can be used to remove Metaldehyde.

Transvac’s range of dosing solutions offer a clean, efficient & flexible interface for handling PAC.


Our unique, fully containerised PAC dosing system, the TransPAC, provides a safe and secure home for your dosing solution and requires no building work. Taste and odour problems are often seasonal, and sometimes relatively short-lived; the TransPAC offers outstanding value as it can be taken from site to site as required, ideal for treating seasonal issues such as algae bloom, taste & odour issues or pesticide contamination, including the successful removal of Metaldehyde.

The TransPAC unit comes with bulk-bag and silo feed options as standard. The technology inside the secure container includes an intermediate hopper, 800 litre header tank, HDMI control panel and Ejector dosing system. Transvac have over 42 years experience in the design, testing and manufacturing of Ejectors, a simple yet ingenious technology that is virtually maintenance free!
