This patented product is an improved version of the inclined plate (pipe) commonly used in water treatment engineering. It does not alter the basic working principle of the inclined plate (pipe), but rather achieves improvements through installation, combination, and changes in process application conditions. It is suitable for retrofitting or new construction of water supply or sewage plants, and can be used for mud-water separation in any treatment process to enhance production capacity or facilitate management. 1. With the improvement of national drinking water quality standards and the aging of some water plant processes, there are approximately 20 million m3/d scale water plants that need to be retrofitted each year in China. If only 25% adopt this technology, the annual profit could reach 10 million yuan; 2. The construction of many new water plants is needed in county towns and new rural areas of China. Estimating at a scale of 10 million m3/d, if 25% adopt this technology, the annual profit could reach 5 million yuan; 3. The country places great emphasis on environmental protection, and a large number of wastewater treatment projects are being built each year. Some of these projects require the use of physical and chemical processes. The estimated annual profit from the promotion and application of this technology is over 5 million yuan.
