The Influence of Shock Disinfection on Durability of Internal Water Supply

Abstract

Water supply is a potentially exposed to bacterial contamination when it is newly constructed or re-introduced. It must pass tests for chlorine concentration and coliform absence before being put into use. Shock chlorination is usually performed preventively. This is a process of disinfecting internal water supply or plumbing systems by circulating a concentrated chlorine solution throughout the system. Shock disinfection is intended to destroy pathogenic microorganisms. During its implementation very aggressive conditions are present. Under these conditions various metals dissolve, which can cause serious damage to the internal water supply network. Before shock disinfection is carried out it is necessary to assess how it should be applied so that disinfection will be successful without damaging the plumbing installation. Carrying out shock disinfection should take into account all the microorganisms to be destroyed and the materials used that are more or less susceptible to corrosion.
