FIELD: chemistry.SUBSTANCE: invention relates to a microbiological regulation method, which is a physical fine filtration method which removes nutrients, bacteria and suspended solid substances from recycling cooling systems. The method involves first adding an oxidising and/or non-oxidising biocide into a recycling fluid media containing nutrients, bacteria and suspended solid substances. Further, the recycling fluid media is passed through a fine filtration system having membranes with pore size of 5 mcm or smaller in order to remove nutrients, bacteria and suspended solid substances from the recycling fluid medium, thereby considerably reducing biocide consumption.EFFECT: low content of microbiological substance, suspended solid substances and nutrients.17 cl, 2 tbl, 2 ex |
