With damaged DNA, the microorganism cannot function properly as the instructions coded in the DNA are missing or altered. As a result of this, the microorganism can neither function nor reproduce as it normally does. UV radiation, therefore, renders pathogens and microorganisms of all kinds harmless. Once exposed to UV radiation, these microorganisms and pathogens eventually die and cannot cause any infection.

The tube’s total length is just under 30 inches with a 2.5-inch diameter. Another key material used in this product is quartz glass. This material is proven to be reliable and safe for a wide range of pH, pressure and temperature. Since these high quality materials come in contact with the water, you have the peace of mind knowing that no toxic chemicals or harmful contaminants will be added to your drinking water.
The unit operates by passing water through the stainless steel chamber, which is the main body of the UV sterilizer. This component is known as the reactor and is equipped with a UV ray emitting lamp. The water keeps flowing past the lamp as it continues to radiate UV rays at a level that will kill off any harmful microorganisms. The operation of this unit is simple and requires no moving parts, which makes it reliable and durable. The unit can sterilize a large quantity of water in little time as it can process 6 gallons of water per minute.
The quartz sleeve works by keeping the UV lamp out of contact with water through a waterproof seal while still allowing the UV rays to pass through it. Hence, the radiation can sterilize the passing water while the UV lamp can avoid water damage. The quartz sleeve has a 90 percent transmittance so that the radiation can reach the water, making this a highly efficient device. The device can eliminate 99.99% of the bacteria in water.
