Biocidal Products for Water Treatment
What Is A Biocide? A biocide is a chemical treatment that is formulated to effectively control microbial growth. Problems caused by un-controlled microbial growth can range from health hazards, the breakdown of chemicals, the development of biofilms , heat transfer losses, restriction of flow and under deposit corrosion. It is therefore critical that the correct biocidal treatment regime is implemented and regular checks are carried out to ensure that microbial population in a wide range of systems including drinking water, down water services, process waters, closed circuits, recreational waters and open cooling systems are kept under control. The control of microbial growth is generally achieved by ensuring systems are cleaned on start up and regularly as required, preventing contamination of systems and dosing with a biocide either on a continuous basis or via a programme of shock dosing.
There are two basic types of biocides: oxidising and non-oxidising. Oxidising biocides include; chlorine, chlorine dioxide, hydrogen peroxide, bromine and ozone. Non-oxidising biocides include: quaternary ammonium compounds, Bronopol, THPS, DBNPA and Gluteraldehyde.
When selecting a biocide for use in a system whether as a biocidal flush biocide, maintenance dose biocide or a shock dose biocide a number of factors need to be considered including: contact time, concentration, temperature, pH, compatability, efficacy against microbes present in the system and cost effectiveness. Our technical department can advise on biocide selection.
Oxidising biocides can generally be used at lower concentrations than non-oxidising biocides and their use tends to be more cost effective.
Among our core chemicals is Ultralox40®, a proprietary active chlorine solution that rapidly kills water borne bacteria, as well as breaking down the biofilms that harbour the pathogens in water systems . It is extremely effective against planktonic and sessile microorganisms at very low concentrations, making it ideal for use in water hygiene and pipework treatment applications where it quickly eradicates Legionella. Pseudomonas and other microbes.
