Automatic Monitoring and Dosing

Commercial swimming pools should have a system installed to automatically dose the disinfection, pH control and coagulation chemicals into the pool water circulation system. Manually dosing chemicals (sometimes referred to as ‘hand-dosing’) is a hazardous activity that can be easily avoided by the installation, use and maintenance of such systems. Hand-dosing chemicals should only be …

Chemical Safety – Know Your pH Correctants

Carbon Dioxide (CO2) CO2 is a non-toxic and non-flammable gas, colourless and odourless but with a characteristic taste and pungency at higher concentrations. The normal concentration of CO2 in the air that we breathe is approximately 400 ppm (0.04% by volume). If its concentration in the ambient air is increased, the pulmonary gas exchange in …

  The most common infections spread in pools and spas are gastrointestinal (e.g. cryptosporidium and viruses) and skin rashes (bacteria mainly). Blood and vomit are unlikely to cause illness, because they are less likely to be infected than faeces and skin and pool disinfectants should kill any bugs that there are, provided disinfectant residuals and pH values …
