Ultraviolet (UV) Light; advantages and disadvantages in the water industry

Ultraviolet (UV) is an electromagnetic radiation. Disinfection using UV radiation is commonly used in wastewater treatment applications and is finding an increased usage in municipal drinking water treatment. Many bottlers of spring water use UV disinfection equipment to sterilize their water. Solar water disinfection has been researched for cheaply treating contaminated water using natural sunlight. The UV-A irradiation and increased water temperature kill organisms in […]

Chloramination; advantages and disadvantages in the water industry
Chloramination; advantages and disadvantages in the water industry

Chloramination is the treatment of drinking water with a chloramine disinfectant. As chloramines are more stable and last longer in water than chlorine, monochloramine is now used mostly as a secondary disinfectant because it provides more effective residual disinfection in the distribution system than chlorination alone.It is used especially where disinfection by-product formation in the distribution system is exceedingly high if free chlorine is used […]

Chlorine Dioxide (ClO2); advantages and disadvantages in the water industry

Chlorine dioxide is a chemical compound with the formula ClO2. This yellowish-green gas crystallizes as bright orange crystals at −59 °C. As one of several oxides of chlorine, it is a potent and useful oxidizing agent used in water treatment and in bleachingThe use of chlorine dioxide for pre-disinfection and oxidation of drinking water has increased significantly over the past 20 years. Chlorine dioxide is […]

Calcium Hypochlorite; advantages and disadvantages in the water industry

Calcium hypochlorite (Ca(OCl)2) is essentially a solid that is used in place of liquid NaOCl.As a mixture with lime and calcium chloride, Calcium Hypochlrite is marketed as chlorine powder or bleach powder for water treatment and as a bleaching agent. In addition to water treatment, Calcium hypochlorite is used in kitchens to disinfect surfaces and equipment. Other common uses include bathroom cleansers, household disinfectant sprays,  algaecides, herbicides, and laundry detergents.Calcium […]
