  • Patent number: 8092688
    Abstract: A method for treating water in a ballasted flocculation system comprises directing water into a ballasted flocculation zone and adding ballast and a flocculation reagent to the water to form a water-floc mixture. The water-floc mixture is directed into a settling zone to form treated water and sludge containing ballast. The ballast is then directed to a recirculation line where the ballast is recirculated to the ballasted flocculation zone. The method further includes determining the ballast concentration and comparing the ballast concentration with a predetermined threshold value. The rate at which ballast is recirculated to the ballasted flocculation zone is adjusted based on the determined ballast concentration and the predetermined threshold value.
