Cooling tower water requires extensive treatment. During Cooling Tower water treatment, three main factors must be controlled.
• Corrosion of pipes and heat exchanger units. • Scaling in pipes and (mainly) in heat exchangers. • Microbial growth (bacteria, algae). These three aspects cannot be viewed separately.
Conventional treatment techniques are mainly applications of chemical biocides, corrosion inhibitors and scale inhibitors. Ozone is a reliable alternative that controls the above-mentioned factors sufficiently.
Benefits of Ozone:
• Safe and easy in use. • Low maintenance costs. • Ozone is produced on-site and requires no storage of dangerous chemicals. • Ozone requires no additional disinfectants. • Micro-organism cannot get resistant to ozone after prolonged use of ozone. • High efficiency as disinfectant. • Very effective in removing bio films. • Ozone is effective in a wide pH range. • Makes the water crystal clear, eliminating all turbidity • Dissolves the scale and inhibits further scaling, hence improving heat transfer and further saving on chemicals and pollution. • Reduced Chemical Usage – Chlorine can substitute for several chemicals in a cooling tower treatment package, reducing and possibly eliminating the use of such chemicals. • Increases dramatically Heat Transfer Efficiency.
