  • Water quality and treatment in public swimming pools

    Public swimming pools all use chlorine, unfortunately the chlorine reacts with ammonium to form a volatile gas called trichloramine. It is the this gas which stings your eyes while swimming, trichloramine also gives swimming pools their characteristic chlorine smell. Trichloramine will damage the mucous linning of your lungs, and in the case of small children it will pre-dispose their lungs ...

  • Nanofiltration for enhanced removal of disinfection by-product (DBP) precursors in swimming pool water–retention and water quality estimation

    Three nanofiltration (NF) membranes with a chlorine tolerance ≥ 1 mg L-1 were applied to reduce DBPs and their precursors in swimming pool water. A lab scale plant with crossflow modules was installed in by-pass at the sand filter outlet of a swimming pool for a period of several weeks. The chlorine tolerances of the membranes SB90 and NP030 were found to be adequate for filtration under swimming ...

  • Chemistries of Ozone for Municipal Pool and Spa Water Treatment

    Ozone generated by ultraviolet (UV) radiation is used in North America for treating (mostly residential) spa and pool waters almost exclusively, while only a handful of North American municipal pools and spas are using ozone generated by corona discharge technology in accordance with well–established German teachings. On the other hand, several thousand European municipal swimming pools and ...

  • Chlorine levels in pools

    In response to a SportExcel CPD seminar in April 2004 on pool water disinfection ISRM is reissuing this updated guidance. Also, recent press reports have highlighted the theoretical risks of high chlorine levels in swimming pools in relation to both pregnant women and levels of childhood asthma. This further reinforces the need for operators to provide the highest pool water standards possible. ...

  • Importance of Air & Water Testing in Indoor Pools

    Have you ever wondered why your eyes hurt or why you have a cough after swimming at an indoor pool? We all assume that it’s from too much chlorine in the pool but that is false! If the pool staff doesn’t regularly test and monitor both the air and water indoors, the environment becomes very toxic and unsafe to everyone in the building. Water is an essential ingredient for all life as ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...
