What is a UV Sterilizer

Posted by Pure Aqua, Inc. on Aug 26th 2020

In the world of water purification and treatment, having an Ultraviolet or UV sterilizer can make your water healthier and prolong the life of water that has been treated and processed. So, what is a UV sterilizer and how does is it further clean the water and kill those nasty little bacteria and microorganisms that can still infest water even after it has been treated.

UV sterilizers are highly efficient in eradicating all presence of microbiological pollution throughout water. However, there must be a sufficient amount of exposure to the ultraviolet rays of the sterilizer in order for proper disinfection to take place. Ultraviolet sterilizers are applicable in a wide range of utilizations, from drinking water in residential areas or small commercial businesses, to larger water sources throughout municipal areas and industrial facilities. Through the years UV technology has become well established as a safer and more cost-effective choice for optimal and economical water disinfection.

A UV sterilizer is undoubtedly your best option for complete disinfection under any setting where bacteria-free, purified water is required and to avoid any further contamination of the water before it is needed for its final point of use.  is useful in almost any application where microbial free, safe and pure water is required; and where there is a chance of the water being contaminated before it reaches the final point of use.

What Is UV Sterilizer?

With UV sterilizers, a wavelength of at least 253.7 nanometers is required for the effective disinfection of bacteria, microbes, algae, viruses, and other biological contaminants which have a propensity to spread quickly. For this reason, the ultraviolet sterilization process is very suitable due to its ability to break down the DNA of microorganisms, preventing any further growth. The end result of the UV sterilization process is the elimination of the total amount of biological contaminants in the water in under 10 seconds of exposure to the UV light. UV sterilizers gain their heralded reputation for these reasons, including highly desirable features such as simple installation, no change in taste, pH, and other characteristics of the water, etc.

How Does UV Sterilization Work?

The ultraviolet rays emitted from the UV sterilizers work by piercing disease-causing agents and killing their DNA. This is important since DNA is the basic foundation of the organism's ability to function and reproduce, so eradicating the DNA prevents these organism's from being active and growing. The energy of the UV rays are similar to sunlight in tiny proportions, but made generated in stronger intensities through the addition of an electric discharge lamp called a UV lamp.

There is a zero percent chance that any microbiological organism can survive the effects of an ultraviolet sterilizer when used in the correct dosage. Thus, the UV process is deemed as the finest option for water disinfection, with no potential of the unit overheating. This consequently results in much cost-saving since there won't be any need to acquire other equipment to combat overheating problems. 

Industries That Use UV Sterilizers

UV Sterilization system is more than just an electric discharging lamp within a pipe. The best manufactured industrial uv sterilizer and commercial uv sterilizers are capable of providing users with magnificent results in various industries such as:

  • Food Processing – The treatment of water is a critical factor throughout the food and beverage industry as it is directly related to human use.
  • Bio- Pharmaceutical – Water used in pharmaceutical and medical items and for CIP (Cleaning in Place) should be clear of pollutants such as ozone, chlorine and bacterial substances. For the purification of water, most pharmaceutical companies rely on ultraviolet sterilizers.
  • Cosmetics – Water free from microbes and pathogens guarantees consistency and increases cosmetics' shelf-life. The suggested alternative for the cosmetics industry worldwide is UV disinfection.
  • Wastewater Disinfection and Reuse – UV sterilization can aid in tackling water shortage issues and increasing fresh water prices through wastewater treatment at the tertiary level. UV wastewater systems can then treat wastewater so that the water can be reused for beneficial purposes such as draining and cultivation.
  • Mining Water Treatment Pure Aqua 's membrane systems are designed to minimize the degree of pollution that is engendered during considerable mining operations. Much of this recycled water can be reworked, which decreases the amount required from local water supplies.
  • Marine Water Purification The desalination systems secure an uninterrupted supply of clean freshwater whilst progressively inadequate and/or polluted water supplies in the world.
  • Military Water Purification Military water purification systems are equipped with careful precision to maintain it is error-free. The end outcome is an effective, dependable, and lasting military-grade water treatment machine that is tried and tested across the globe in the military industrial complex.

What are the Benefits of UV Sterilizers

Versatile - Capacities available from 40 to 1,300 gallons per minute.

Environmentally Friendly – No harmful byproducts are produced during the disinfection process.

Efficient – All recognized biological organisms are vulnerable to an ultraviolet sterilizer.

Economical – Most cost-effective disinfection system in the market.

Safe and Chemical Free – No introduction of chemicals, hence no chance of overdose.

Fast – The UV process works instantly when the UV rays comes into contact with an organism.

Easy to Manage – Advanced features allow for terrific accuracy and monitorization. 

Do UV Sterilizers need periodic maintenance?

There are certain instances that occur in which the water is not sufficiently pretreated and turbidity levels are insignificant. As a result, it is possible to conduct regular monitoring and sanitation every 6 months. The cleaning rate might need to be improved in the event of high turbidity and durability. Eventually, the existence of the UV lamp is reduced, and should be alternated until it is depleted. The testing circuit should deliver the trigger to suggest substitution in the remote chance of premature lamp failure.
