Alternative Action Whether it’s chemicals products or systems such as UV and Ozone, when it comes to low and no chlorine options, there’s no shortage of solutions on offer. The alternative approach for treating water with zero or reduced amounts of chlorine shows no signs of slowing up as people seek an alternative way to treat water. We look at some of the available options to reduce chlorine usage in pools and spas By Karen Witney


or a number of years the industry has been put under pressure to come up with pool and spa disinfection that does not rely solely on chlorine or bromine to sanitise and is safe and trustworthy. There are now many alternative treatments available that are just that. Low to no chlorine, it would seem, is the way forward in both domestic and commercial situations and is a welcome alternative for indoor pools to eradicate chemical smells. Chlorine will always have its place in pool sanitation but the alternatives are fast gaining ground.

LO-CHLOR CHEMICALS NEW STARVER X® FROM TOTAL WATER PRODUCTS For many years Lo-Chlor Chemicals has been recognised as the global leader in phosphate removal, which began in the mid 1990’s with the launch of Starver®. Advancements in this area have changed the way we treat algae in both domestic and commercial swimming pools. By reducing phosphates and eliminating algae we reduce the demand for chlorine as a sanitiser – therefore pools can operate over a season with much lower levels of chlorine consumption. Starver® technology is now sold in over 50 countries worldwide and its popularity has become recognised as the most revolutionary and effective speciality chemical to reach the pool and spa market to date. Developed in Australia in 2013, Revolutionary phosphate neutraliser Starver® from Total Water Products enhances water clarity and increases sanitiser efficiency 51-54_SPN_Aug_2015_Alternative_Approach_Feature_rev.indd 51

This attractive leisure centre pool is effectively and continuously protected with HydroXan® from Gaffey Technical Services

and now manufactured in the UK, StarverX® efficiently reduces high levels of phosphates before switching back to using the original Starver® as the ongoing preventative maintenance treatment. The proprietary blend of rare earth compounds effectively acts as a ‘shock treatment’ for high levels of phosphate (above 1.5ppm) and will neutralise and remove dissolved phosphate within 24 hours. This highly concentrated, unique formulation removes higher levels of phosphate than any other product and is compatible with all pool treatments and equipment.

HYDROXAN® FROM GAFFEY TECHNICAL SERVICES Protect water hygiene and reduce the energy demand of the pool with HydroXan®, a patented non-hazardous liquid TCDO compound producing a safe, controlled residual of chlorine dioxide in chlorinated

pool water. Chlorine dioxide is well known for its efficiency as an oxidiser, being particularly effective in destroying biofilm, known to harbour pathogenic bacteria such as Legionella and Pseudomonas species. Chlorine dioxide is also effective in destroying Cryptosporidium, with HydroXan® being used successfully in the clean-up of several high profile outbreaks in the UK and Europe. HydroXan® is dosed into the pool flow continuously in very small quantities to produce a constant low-level chlorine dioxide residual throughout the pool, allowing a significant reduction in the consumption of chlorine whilst providing an additional boost to disinfection throughout the whole pool. Irritant chlorine by-products and odour are also significantly reduced, improving the comfort and health of bathers and pool-side staff. The advantage of HydroXan® is that chlorine dioxide
