Ultraviolet light treatment is a widelyrecognized and proven method of disinfection of water and has several advantageover other disinfection methods such as chlorination, ozonation, etc. UV lightdoes not add anything to the water, such as, undesirable color, odor, taste, orflavor, nor does it generate harmful byproducts. It adds only energy in the UVradiation. Also, UV disinfection requires only a fraction of the contact timesrequired by other disinfection methods. It is fast, efficient, effective,economical and environmentally-friendly.
Principle of Operation
UV water disinfection system design has beencarefully conceived to provide adequate germicidal dosage throughout thedisinfection chamber. The dosage, as it applies to UV disinfection, is afunction of time and the intensity of UV radiation to which the water isexposed. Exposure time is related to the flow rate, the higher the flow rate,the lower the exposure time or the lower the flow rate, the higher the exposuretime. The UV intensity is the amount of energy, per unit time, emitted bygermicidal lamp. The Dosage is the product of UV intensity and the exposuretime.
Limitation of Use
The UV water disinfection system NOT intendedfor the treatment of water that has an obvious contamination or intentionalsource, such as raw sewage, nor is the unit intended to convert wastewater tomicro biologically safe drinking water.
Water Quality (in)
Water quality plays a major role in thetransmission of germicidal UV rays. It is recommended that
