Rain Water Harvesting Purification

With the use of ultraviolet germicidal energy in rain water applications on the rise, the need for cost effective, “green” methods have been aggressively pursued. Some areas of use in a green environment where UV may be beneficial is showering, washing of clothes or even drinking, dependent upon the type of system in the line process.

Considerations for ultraviolet use include, effective pre-filtration and routine testing. Ultraviolet lamps must “see” the target microorganisms in order to effectively destroy them. Large and even small scale particulates can deter the performance of the UV rays by masking bacteria. Proper pre-filtration methods can remove these particulates, allowing the lamps to operate at their full potential. In the event that water is trapped or near a contaminated source, it is crucial to test the quality of the water on a continuous basis.
