  • Water purification apparatus and method for using pressure filter and pore control fiber filter
    Patent number: 8557114
    Abstract: The present invention provides a water purification apparatus and method using a pressurized micro-filter preprocessed with a coagulation inclined-plate sedimentation reservoir and a pore-control fiber filter for improvement of a recovery rate, which removes the dissolved organic materials and the turbidity of raw water through a preprocess by a flash mixer, a two-stage coagulation reservoir and an inclined-plate sedimentation reservoir, thereby making it possible to reduce the use of coagulants, the generation of sludge by-products, the inflow load of membranes, and the facility size in comparison with the conventional standard water purification processes.
    Type: Grant
    Filed: April 15, 2010
    Date of Patent: October 15, 2013
