Cooling Circulating water

Pain Points of Cooling Circulating Water

Cooling circulating water systems face a series of severe challenges during operation, including microbial growth, biofilm formation, scaling, and corrosion. These issues are primarily controlled by traditional chemical treatment methods (such as chlorine-based disinfectants and corrosion and scale inhibitors). Ultraviolet (UV) disinfection technology, ozone (O3) technology, and ultraviolet advanced oxidation processes (UV-AOPs) offer significant potential as alternatives or supplements to traditional chemical treatment methods due to their unique green, additive-free disinfection and oxidation properties.

Application of UV and Ozone in Cooling Circulating Water:

In industrial cooling circulating water, the primary goal of UV disinfection is to control the growth of microorganisms such as bacteria (such as Legionella) and algae, preventing the formation of biofilms on heat exchanger surfaces and pipe linings. Biofilms not only reduce heat transfer efficiency and increase energy consumption, but also induce microbial corrosion (MIC), shortening equipment life.

Ozone (O3) is a strong oxidant. In water, ozone can react with pollutants through direct oxidation and indirect oxidation. It inhibits the formation and development of biofilm by killing microorganisms and oxidizing the biofilm matrix. Ozone can loosen and fall off the organic matter in the oxidized scale layer, or change the crystal form of calcium carbonate, thereby playing a certain role in descaling.

Ultraviolet advanced oxidation process (UV-AOP) is a water treatment method that uses ultraviolet light irradiation combined with one or more oxidants (such as hydrogen peroxide (H2O2) and ozone (O3)) or catalysts to generate large amounts of highly reactive hydroxyl radicals (OH) in situ. Hydroxyl radicals possess extremely strong, non-selective oxidative power, rapidly degrading various difficult-to-degrade organic pollutants and killing microorganisms in water. UV-AOP exhibits unique application potential in industrial cooling water systems with stringent water quality requirements or the presence of specific contaminants.
