  • Rotary disc filter with automatic integrated backwash and chemical cleaning system
    Patent number: 9962635
    Abstract: A rotary disc filter is provided with an integrated backwash and chemical cleaning system. In one mode of operation, backwash is directed through a control valve to one or more nozzles for spraying the backwash onto the filter media forming a part of a rotary disc filter. In a second mode, a chemical cleaning mode, the pump directs backwash through an eductor that induces a chemical into the inductor which is mixed with the backwash to form a backwash-chemical mixture that is sprayed onto the filter media. A control system is used in conjunction with the backwash and cleaning systems to monitor process information and/or filter media properties and to determine when to perform backwashes and regenerative cleanings in order to optimize the performance of the filter system.

  • Process for Inhibiting Biological Growth On a Gravity Fed Disc Filter
    Publication number: 20140124461
    Abstract: A rotary disc filter is provided with a system for inhibiting biological fouling from biological growth on filters that form a part of the rotary disc filter. A biocide is pumped from a biocide supply tank to a manifold and mixed with a backwash to form a backwash-biocide solution. The backwash-biocide solution is sprayed onto filter media during a backwashing operation and the presence of the biocide inhibits and eliminates biological growth on the filter media.
