Capacity of Ultra Violet Disinfection SystemsThe capacities of Ultra Violet Treatment Systems vary from 0.5 gallons per minute (gpm) to several hundred gpm. This is designed a holistic, in-line, point-of-entry system that treats all the water used in the house. However, there are certain point-of-use devices (treating water from a single tap) that may include ultra violet as a final disinfection method. This is especially used with train systems such as reverse osmosis. The effectiveness of Ultra Violet treatment depends upon intensity of radiation and contact of bacteria with radiation. To ensure that particles are not shielded in the water, pretreatment to remove turbidity may be required. While the Ultra Violet treatment system is very effective, it has an upper limit to the number of bacteria that can be treated. An upper limit for ultra violet disinfection is 1,000 total coliforms/100 mL water or 100 fecal coliforms/100 mL. To summarize, Ultra Violet Radiation Treatment System for water purification
is an effective system. System effectiveness is dependent on the intensity of
the lamp and this must be ensured with periodic cleaning/replacement. The system
is best used at the point of use after a pre filtration such as carbon
filtration and reverse osmosis.
