CLO2 SYSTEM /Generator
Introduction:
Chlorine dioxide is one of the fastest growing Chlorine alternatives in water treatment solutions. This technology offers the benefits of effectiveness at high pH, being unaffected by ammonia, and demonstrating significant advantages over Chlorine in systems susceptible to high levels of organic contaminants. Because Chlorine dioxide is a selective oxidizer, its ability to control microorganisms in water at very low dosages makes it an especially cost effective solution. Solubility: Chlorine Dioxide is approximately 5 times more soluble than chlorine and 50 times more soluble than ozone. Even though Chlorine Dioxide is soluble, it is still a gas and the solubility of the gas is governed by Henry's Law. In closed pipelines, virtually no loss out of water into the gas phase can be expected. In open tanks, Chlorine Dioxide in solution will slowly decrease until equilibrium is established between ClO2(g) and ClO2(aq). According to Le Chatelier’s Principle, if Chlorine Dioxide is continually removed from the gas phase above an open tank, the concentration in solution will continue to decrease until it reaches zero.
Advantages:
- Chlorine dioxide is effective over a broad pH range.
- Chlorine dioxide has 2.5 times the oxidizing capability of Chlorine.
- Required contact time for Chlorine dioxide is lower compared to Chlorine.
- Chlorine dioxide has the ability to penetrate and remove bio film formed and kill bacteria, spores and viruses.
- Chlorine dioxide is less corrosive than chlorine and does not hydrolyze to form acid.
- Chlorine dioxide does not form chloramines.
- Chlorine dioxide does not form trihalomethanes upon reaction with organic matter
