Advantages and disadvantages of chlorine disinfection for villa swimming pool equipment. The method can be easily applied at small communities of the world that do not have a centralized water treatment plant or access to other treatment or disinfection alternatives, such as filtration or chlorination. Identify the difference between the physical and chemical disinfection techniques. One of the main advantages of nanofiltration as a method of softening water is that during the process of retaining calcium and magnesium ions while passing smaller hydrated monovalent ions, filtration is performed without adding extra sodium ions, as used in ion exchangers. Hypochlorites are less pure than chlorine gas and are less dangerous. Hypochlorites Instead of using chlorine gas, some plants apply chlorine to water as a hypochlorite, also known as bleaching powder. Engineering Facility Innovation in engineering facility.
