ABSTRACT

Cooling circuits are used in numerous industrial operations around the world.  Water entering these systems must be constantly monitored and adjusted. Water treatment has two main objectives: to assign lowest amount of cooling water and to protect the cooling system from corrosion, biological and mineral deposits. The technology for water treatment has to develop together with industrial needs. Membrane separation processes represent appropriate processes for treatment of industrial cooling waters. The aims of this study was to determine the effectiveness of reverse osmosis (RO) membrane in removing compounds responsible for water hardness, and by using a computer program ROSA8 simulate 80 % softening efficiency while continuously supplying plant with 880 m³h^-1 of cooling water.

Keywords: cooling water, incrustations, reverse osmosis, modeling, ROSA8
