IPC: C02F1/28
Filed: 2002-08-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide a water treatment method which can increase the amount of product water and can reduce the running cost required for water treatment and an active carbon treatment apparatus.  <P>SOLUTION: The water treatment method includes a filtering step of filtering water to be treated by passing the water through active carbon layers 4 and a back washing step of back washing the layers 4. The filtering step includes a fluidizing step of fluidizing the active carbon particles in the surface layer sections 4a of the layers 4. According to this water treatment method, the active carbon particles in the sections 4a of the layers 4 are fluidized in the filtering step, thereby the gaps between the active carbons with each other are widened and the pathways for filtrate are assured. The suspended substance caught in the sections 4a are eventually caught even in the deep parts of the layers. Namely, the suspended substance is caught not only in the surface layer sections of the layers 4 but in the deep parts as well and the suspended substance can be sufficiently caught by effectively utilizing the entire layer of the layers 4. The time for continuation of the filtration can therefore be prolonged and the frequency of backwashing can be reduced.  <P>COPYRIGHT: (C)2004,JPO
