<P>PROBLEM TO BE SOLVED: To provide a new waste water cleaning technique capable of regenerating waste salt water economically in a short time even for the waste salt water contaminated with impurities of vegetable fine pieces or the like produced in a food processing plant into a cleaned salt water adjusted to a desired salt concentration to reuse the cleaned salt water in the same food processing plant. <P>SOLUTION: The salt water recycling system 1 includes: a solid-liquid separation tank 2 capable of hygienically recovering only waste salt water containing salt contents recovered from the food processing plant 7 in large amounts, and capable of precipitating and removing unnecessary components contained in the recovered waste salt water; a salt content recycling device 3 capable of removing the remaining unnecessary components contained in the waste salt water, having either one side of microfiltration membrane and ultrafiltration membrane through which chloride ions are allowed to pass; and a storage tank 4 capable of hygienically storing the cleaned salt water adjusted to a prescribed salt content concentration, and capable of supplying the cleaned salt water to the food processing plant 7. <P>COPYRIGHT: (C)2011,JPO&INPIT |
