Recirculating Water |
Closed recirculating water system, water circulates in a closed cycle and subjected to alternate cooling and heating without air contact. Heat, absorbed by the water in the closed system, is normally transferred by a water-to-water exchanger to the recirculating water of an open recirculating system, from which the heat is lost to atmosphere.
High-quality water can usually be used for makeup, and as a result, scale deposits are not a problem.
The use of high-quality water also minimizes the dangers of cracked cylinders, broken heads, fouled exchangers, and other mechanical failures.
Open recirculating water systems are inherently subject to more treatment-related problems: Cooling by evaporation increases the dissolved solids concentration in the water, raising corrosion and deposition tendencies the relatively higher temperatures significantly increase corrosion potential, the longer retention time and warmer water in an open recirculating system increase the tendency for biological growth microorganisms and nutrients can also be absorbed into the water across the tower.
Side stream filtration
A small portion (5-10%) of the cooling water is continuously filtered and returned to the system. This is known as side stream filtration, which is proven method of removing suspended solids from cooling tower systems.
Side stream filtration is a practical and efficient mean of reducing maintenance and downtime of condensers, heat exchangers and cooling towers.
Side stream filtration also reduces costly replacements of pump casings and seals, valve seals and other process components.

On- site chlorination
Several companies began to explore the idea of making smaller electrolytic equipment that uses common salt in order to move the process on site, and eliminate the transportation and storage of hazardous chemicals. On-site generators can be designed to produce either hypochlorite or mixed oxidants at concentrations less than 1 percent of free available chlorine
Mixed oxidants offer superior disinfection efficiency, elimination of biofilm, more durable chlorine residual, reduced formation of disinfection by-products, and improved taste and odor.
PuriChem offers complete on- site Chlorination systems for your industrial applications.
