| 20110155669 | METHOD FOR TRACE PHOSPHATE REMOVAL FROM WATER USING COMPOSITE RESIN - The invention discloses a novel method for trace phosphate removal from water by using a composite resin. Firstly, adjusting the pH value of the raw water to 5.0˜9.0 and prefiltering the water, then leading the filtrate through an absorption tower packed with the composite resin, the trace phosphate in the water is therefore absorbed onto the composite resin; stopping the absorption run when it reaches the leakage point, using a binary NaOH-NaCl solution as the regenerant of the exhausted sorbent, followed by rinsing the composite resin-filled absorption tower with saturated carbon dioxide solution to regenerate the resin. In this invention, a composite resin with nanosized hydrated ferric oxide (HFO) or hydrous manganese dioxide (HMO) particles loaded on its surface is adopted as the absorbent for enhanced phosphate removal from water. A significant decrease of phosphate content in the effluent from this treatment system is found from 0.05-20 ppm to less than 20 ppb (calculated in P), despite of the coexisting competing anions as sulfate, chloride, and hydrocarbonate at much higher molar concentrations than phosphate. This invention is characteristic of large treatment capacity and efficient regeneration for repeated use of the absorbent. | 06-30-2011 |
