How could coliform bacteria affect water quality?
What are coliforms? Coliforms are bacteria that are always present in the digestive tracts of animals, including humans, and are found in their wastes. They are also found in plant and soil material. The most basic test for bacterial contamination of a water supply is the test for total coliform bacteria. Total coliform counts give a general indication of the sanitary condition of a water supply. Total coliforms include bacteria that are found in the soil, in water that has been influenced by surface water, and in human or animal waste.
Use ultraviolet (UV) light to disinfect water that is contaminated with coliform bacteria. A UV light is held in a protective sleeve and all infected water is passed through the area. UV light rearranges the DNA structure of the bacteria, making it impossible to reproduce.
Because of the sterilization lamps, your UV purification system is capable of killing 99.99 percent of the bacteria in the water supply. Because of this benefit, this type of filter is regarded as a leading purifying unit.
Ultraviolet water filters have the capacity to kill different microorganisms. These include E. coli, coliform, salmonella, and other harmful bacteria.
Advantages of UV Technology
UV disinfection has been successfully applied worldwide for decades, and has numerous advantages over chemical disinfection methods:
• Effective for all types of microorganisms, including bacteria, viruses, fungi, and protozoa such as Cryptosporidium and Giardia
• Chemical-free technology, eliminating chemical transport, storage, handling or removal
• Non-corrosive and no hazards associated with accidental overdosing
• Low capital and operating cost
• Easy to operate and maintain
• No disinfection by-products (DBPs) of health concern formed
• Compact and easy to retrofit
• Efficacy is independent of pH
• No impact to the aesthetic quality of the water (taste, odor, color)
• Safe and environmentally-friendly
In General, a UV system is simple to install and requires little supervision, maintenance, or space. UV lamps are simply replaced once a year.
One of the most common uses of ultraviolet sterilization is the disinfection of domestic water supplies due to contaminated wells. Coupled with appropriate pre-treatment equipment, UV provides an economical, efficient and user-friendly means of producing potable water.
