Chlorine Dioxide for Waste Water Disinfection

Chlorine dioxide has demonstrated its effectiveness not only in the disinfection of drinking and utility water but also in the field of wastewater treatment. Unlike chlorine, it maintains its stable activity against microorganisms due to its resistance to hydrolysis in water. It also exhibits the ability to eliminate coliform populations in wastewater.

Compounds that cause odor and color in water are typically derived from inorganic salts (such as iron and manganese derivatives), sulfur compounds, organic species from algae and moss, and organic compounds from pollutant sources. Chlorine dioxide is used as an oxidation agent due to its ability to oxidize iron and manganese compounds. In addition to odor and color removal, it is effective in the removal of unwanted organic compounds. Unlike other chlorine-based products, chlorine dioxide does not generate halogens such as trihalomethanes during disinfection in organic-laden wastewater.

Chlorine Dioxide on Microorganisms

The effectiveness of chlorine dioxide on microorganisms commonly found in wastewater, such as Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Enterococcus hirae, Enterococcus faecalis, Enterococcus faecium, Candida albicans, Aspergillus niger, Klebsiella pneumoniae, Proteus mirabilis, and Legionella pneumophila, has been reported by laboratories.
