Abstract
This is a method that is an environmentally friendly hybrid microbiological control compromising a physical method through fine filtration, which removes nutrients, bacteria and suspended solids from open recirculating cooling systems. The method for microbiological control in cooling systems wherein a recirculating fluid containing an oxidising or a non-oxidising biocide or a mixture of an oxidising and a non-oxidising biocide and is passed through a fine filtration system rsulting in reduced microbiological matter, suspended solids and nutrients.

Biocide consumption and chemical microbiological treatment procedures. Background technique [0004] Particle separation can be performed based on size exclusion. Larger size particles are easily removed by sand filtration. However, only filters with sm...
