Recycling System and Processes of the Waste Brine and the Waste Water in Kimchi Factory

摘要

PURPOSE: A treatment method of brine and washing water derived from cabbage salting process is provided, which can reuse brine washing water so that can reduce production cost of Kimchi. The recovered waste brine is reused after the salinity is adjusted to 12-17%. CONSTITUTION: The treating method comprises the following steps: (i) separate and recover brine and wash water from cabbage salting process; (ii) remove suspended matter by primarily passing the recovered brine and wash water through an inclined metal net filter(10) that is equipped with different meshes; (iii) remove residual matter that is not passed through the metal net filter(10); (iv) filter the filtrate by three stage water purifying treatment tank(11) that is composed of a metal nets(15) of 1.0-4.0 mm, 0.149-2.00 mm, 0.074-0.297 mm, sand filter(16) and activated carbon basin(17); (v) filter again the brine and wash water which are filtered already by filter(12); and (vi) sterilize the filtered brine and wash water by ozone generator or chlorine sterilizer, the treated waste brine being reused after the salinity adjusted.
