Cleaner production means the production process , products and services continued to use the overall preventive environmental strategies to increase eco-efficiency and reduce drop human and environmental risks. For products , cleaner production means less and reduce the use of products from raw materials to the final disposal of the entire lifecycle of adverse effects. For production processes , cleaner production means saving raw materials and energy , the abolition of the use of toxic materials in the production process prior to discharge of waste reduction down the volume and toxicity of waste . The service requires that environmental considerations into the design and the services provided . Water purification in the raw water into drinkable tap water , the whole water purification process, whether it is to enhance , purification, disinfection, pressurizing and distribution and other sectors, must consume large amounts of energy and raw materials , to achieve cleaner production , mainly through the system of water technology to transform and strengthen enterprise management , to ensure a good case of water , energy conservation, so that resources can be fully utilized . The basic thesis through the water as well as the raw water , finished water analysis of the situation , combined with a variety of pre- processing techniques used in domestic situations , comparison of various pretreatment experiments, ozone - activated carbon treatment process can meet in 2001 promulgated regulations for drinking water and water quality objectives and requirements of Shanghai in 2010 . After addition of potassium permanganate and manganese experiments carried out efficiently clarifiers such adaptability experimental design and outlined the new process, a new analysis of existing production processes and propose preventive aspects of pollution , eliminating , weakening measures , and finally after the entire process is estimated economic loss of its environmental analysis.
