Ultraviolet radiation can be used as a pre-treatment or polishing step to sterilize and disinfect water. UV systems are typically used to pre-treat a water supply that is considered biologically unsafe (lake or sea water, well water, etc). The UV disinfection process is a non-chemical method for destroying microorganisms by altering their genetic material, and rendering them unable to reproduce. Most UV systems have stainless steel reactors or reactor linings. Read more here
Ultraviolet Water Systems
Standard Ultraviolet Purification System Components
UV radiation from ultraviolet water systems alone is not suitable for water with high levels of suspended solids, turbidity, color, or soluble organic matter. These materials can react with UV radiation, and reduce disinfection performance. Water turbidity makes it difficult for the ultraviolet radiation to penetrate water. If your water supply has these characteristics, a Sediment Prefilter
(5 micron or less) should be installed before your UV water purification system
to remove particulate matter prior to UV water disinfection.
There are several advantages of using UV water filtration system rather than a chemical disinfection solution (such as chlorination):
No known toxic or significant nontoxic byproducts
No danger of overdosing
Does not require storage of hazardous material
Adds no smell to the final water product
Requires very little contact time
UV Water System Applications
Applications include private wells, campgrounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, water systems, laboratories, marine, pharmaceutical, dairies and many other applications.
*Safety and Efficiency NOTE: Bare skin contact with the quartz envelope must be avoided. Compounds from the skin when heated on lamps operating at 600 to 850°C will form permanent etching (devitrification) on the quartz surface, decreasing UV energy transmission. A contaminated lamp eventually will overheat, causing premature failure. Alcohol wipes and rubber gloves are included with every purchase of a quartz sleeve or lamp.
NOTE: In case of contact with bare skin, decontaminate lamp with alcohol wipe before returning to use.
