Chlorination and Biofouling Control in Industrial Cooling Water Systems

摘要: Chlorine, a powerful oxidizing biocide, was first used in Europe and North America the early 1900s for disinfection of drinking water resulted dramatic decline typhoid cholera cases. At present time, it is largely as treatment, such taste odour control, wastewater, food industry biofouling control. Of all disinfectants, certainly most extensively studied with regard to chemistry, toxicity ecotoxicity. Due its well-tried technology, long-term worldwide industrial uses reasonable cost, chlorine remains common antifouling treatment cooling systems. An ideal biocide toxic one particular organism or group organisms, but has no harmful effects on “non-target” organisms. It not consumed by reactions substances (i.e. there “demand”), soon after enters environment, breaks down into non-toxic forms. Chlorine long way from being an biocide: non-specific reacts virtually constituents natural waters—including man-made pollutants—to yield products having varying degree persistence toxicity. Nevertheless, continues be control power plant
