About DesoClenz™

DesoClenz™ system is a multi-purpose pool filter media treatment.

Swimming pool filters (silica sand, activated carbon and glass based filter media) need regular maintenance to ensure optimum filtration performance. The period between each maintenance cycle depends upon the bather loading, backwash frequency and system design.

Dull looking pool water or high combined chlorine levels usually indicate that a maintenance cycle is long overdue and an overdue maintenance cycle can put bathers at risk and expose them to unnecessary pollutants.

Pollutants can range from human body fats and skin particles through to bacteria and biofilms which can break through into the pool from a contaminated filter bed. Inefficient filtration performance also exposes the pool facility to greater risk from pathogenic organisms, such as Cryptosporidium, which are able to survive for long periods in chlorinated pool water.

An outdated and expensive maintenance option is the dig out, disposal and replacement of filter media. The disposal and replacement of filter media has a negative impact on the environment and used filter media contaminated with human body fats and bacteria may be considered as hazardous waste requiring appropriate and approved disposal methods, both costly to you and the environment.

This method of maintenance also has a lengthy down time for the pool operation whilst the dig out, disposal and replacement of media is carried out. This means that your pool may be out of business during the whole of this period.

A much more cost effective, faster and environmentally friendly method of maintenance is the DesoClenz™ system.

The DesoClenz™ system is a muiti-purpose pool filter media treatment procedure which cleans and disinfects the entire filter system. DesoClenz™ uses DesoPur®, a patented TCDO- chlorine dioxide liquid agent for the cleansing and regeneration of silica sand, activated carbon and glass based filter media.

The DesoClenz™ system is a safe, fast and economical treatment which minimises pool downtime, H&S risks and reduces the carbon footprint of your pool operation. With DesoClenz™ there are no waste disposal or spillage issues.

Facilities with two or more pool filters can normally be treated without closure of the pool. The DesoClenz™ treatment eliminates the transportation involved with disposal and the supply of replacement media, offering a more environmentally friendly maintenance option.
