  • Electrochlorination system: a unique method of prevention of biofouling in seawater desalination

    Desalination plants require huge volumes of seawater for the generation of fresh water. Seawater contains large amounts of microbiological fluids which, when passed through the piping system, form biofouling in the inner surface of the pipeline, which results in the reduction of the flow rate of water without proper chemical treatment. Chlorine is the most commonly used disinfectant for water ...
