B+W's Aftersales division have serviced and maintained the filtration equipment including the ozone plant at Tonbridge Swimming Pool since its construction in 1995. With the ozone plant nearing the end of its working life the client decided to replace the ozone plant with Ultra Violet secondary disinfection along with automated backwashing of the existing filter vessels. The works consisted of refurbishing the three indoor pool filter vessels, installing two Hanovia Swimline UV systems and the installation of an automated backwash system on all three pools. The automated backwash system is integrated with the existing electrical controls and the Siemens energy saving systems that include the chlorine control systems. This provides the client further cost reductions on water and chlorine consumption combined with savings on heating costs. The works were carried out with a small closure to the learner pool and without any inconvenience to the use of the fitness and outdoor pools. The client has expressed his delight in the quality if the installation and the time taken to complete the works with little or no inconvenience to the bathers.
