Ca5(OH)(PO4)+6H20 Efficient removal of phosphate from phosphate-containing water requires the presence of calcium and hydroxide ions. The method of bringing the particles of the composite solid made of calcium silicate into contact with water may be a fixed bed method or a fluidized bed method.0 Usually 9 to 300
Use something similar to mesh. In the fixed bed type, water is passed in an upward flow or a downward flow at a flow rate of Sv1 to 10/hr to precipitate calcium phosphate crystals. For deep water 1, it is desirable to remove the trapped M'f'JA through pre-treatment.0 If clogging occurs during flowing water, backwashing should be carried out periodically using upward flow. It is desirable to remove impurities adhering to the surface by washing with water.The conditions for water flow during backwashing are a flow rate of 20 to 80 m/hr.
The PI degree and time are about 5 to 60 minutes.
