The V-shaped filter is called AQUAZUR V-shaped filter, which is a fast filter developed by the French company Deliman. It is named because of the V-shaped groove in the water. It was first used in the Paris Orly water plant in the late 1960s, and gradually became widely used in Europe in the 1970s. After being applied in Italy, Israel, Morocco, Honduras, Venezuela and other countries, it was praised by various countries and gradually promoted internationally. Since the 1980s, China has also recognized the unique flushing effect of the innovative gas-water backwashing technology abroad, and has successively introduced foreign advanced gas-water backwashing technologies for use in new expansion water plants.
China's first V-shaped filter was put into production in Xi'an in 1987, followed by Chongqing, Xi'an, Daqing, Shenyang, Zibo, Wuhan and other urban water plants. Since the 1990s, almost all of the newly built large and medium-sized water purification plants in China have adopted V-type filters as a water filtration process to improve the water production process, water plant automation and production management level. .
