  • Patent number: 6123848
    Abstract: A process and apparatus for purifying water-insoluble particles is disclosed. The process comprises the steps of continuously recirculating a fluid aqueous suspension of the water-insoluble particles between a filtration system and a suspension reservoir; continuously conducting ultrafiltration of the recirculating suspension at the filtration system to separate an aqueous permeate containing the water-soluble impurities from the recirculating fluid aqueous suspension; continuously discharging the permeate generated by ultrafiltration; adding water to the recirculating fluid aqueous suspension undergoing ultrafiltration at approximately the same volumetric rate per hour as permeate is being discharged; monitoring the purity of the recirculating fluid aqueous suspension; and recovering the purified fluid aqueous suspension after the recirculating fluid aqueous suspension has reached a predetermined purity condition. An apparatus is also disclosed for carrying out the above process.
