Abstract:Appropriate online measuring instruments are provided in air-water backwashing V-filters to ensure a constant water
level of the filtering process by adjusting the opening of clean water valves using advanced PLC automatic control system. When airwater
backwashing process is performed, appropriate washing methods and intensities are employed to wash away the deposition
while maintaining certain amount of biofilms on the surface of the filter medium to ensure later filtration effect
