What Is a UV Water Sterilizer And How Does it Work?

A UV sterilizing system is a water treatment method to kill dangerous waterborne pathogens. It harnesses that same power as the sun and uses a specific wavelength of non-visible light creating ultraviolet radiation. The UV radiation that the sun produces can be divided into three main groups: UV-A, UV-B, and UV-C.  The ultraviolet (UV) water purification technology uses UV-C which is the shortest of all the UV wavelengths and is the least harmful UV light to us.

This system should only be used with the intention of eliminating living organisms, as it won’t remove particles, chemicals, taste, or odors from water. 

Where can the UV light Water Sterilizer system be used?

Food and Beverage – UV sterilizing system can help to achieve High-quality water as per specifications laid down by the FDA ( Food and Drug Administration)

 

Bio-Pharmaceutical – Water used in Pharmaceutical and healthcare products and for CIP (Cleaning in Place) must be free of chemicals like chlorine, ozone, and pathogens. Most pharmaceutical companies depend on UV systems for water disinfection.

 

Cosmetics – Water that is free of microorganisms and toxins ensures quality and enhances the shelf life of cosmetics. UV Sterilization is the preferred choice for the cosmetic industry across the globe.

 

Centralized Drinking Water – A UV drinking water disinfection system is an easy, affordable solution to ensure pure water in each and every tap of your home or office.

 

Waste Water Disinfection and Reuse – To combat the problems of water scarcity and the rising cost of freshwater, UV Disinfection can help by treating the wastewater in the tertiary stage. UV systems that are specially designed for wastewater can thus disinfect wastewater so that the water can be reused for secondary purposes such as flushing and gardening.

Swimming Pools – Traditionally, chlorine has been in use to ensure clean water in swimming pools. However, it is increasingly being known that with chemical disinfection, chemical reacts with many other organic matters to form hundreds of new chemicals which are harmful. While UV is recognized as a safer and more cost-effective way to disinfect swimming pools.

7 Benefits and advantages of UV Disinfection System

1. Natural – UV is nature’s way of purification.
2. Environmentally Friendly – No Toxic by-products are formed during the UV disinfection process
3. Effective – All known microorganisms are susceptible to UV light
4. Economical – Lowest operating cost amongst disinfection systems
5. Safe and Chemical Free – No addition of chemicals, no chlorine taste, and no corrosion problems.
6. Fast – Water is ready for use as soon as it leaves the purifier
7. Versatile – Capacities available from 2 to 800 gallons per minute (g.p.m.).

UV Water Sterilizers for your home

UV systems are POE (point-of-entry), which means you install them before the water enters your home to purify the water throughout your house. Most of the time, typical household pressure is enough for a UV system to operate.

UV water sterilizers come in a wide variety. The size UV system you need depends on the flow rate of your water. Sizing according to flow rate allows water to contact the germicidal wavelength long enough to be effective. Like the size, the price of UV systems varies, but it’s super affordable!

Is UV Safe?

A UV Sterilization System for Water Treatment is perfectly safe. If you are performing maintenance on your ultraviolet (UV) water purification system, make sure the unit is unplugged as staring directly into the light or touching the bulb while it’s still on can cause damage to you.

UV System Maintenance 

An ultraviolet sterilization system requires very little maintenance. These systems run continuously and the bulbs will have to be replaced annually. 

Most systems have an alarm that will remind you when the maintenance is due. It is important to pretreat the water before the UV light to prevent the quartz sleeve from scaling over.

If this pre-treatment is not utilized, then quarterly cleaning of the quartz sleeve may be required for your ultraviolet disinfection system.

What to Consider Before Buying

Basic Of Installation

You’ve got UV water purifiers on the wall and tabletop. Choose one based on your comfort. It is safer to set up a UV water purifier for you if you do have specialists. Much further from every manufacturer, however, carries out the assembly work.

The Available Space 

UV systems are available in all sizes, some of which need more room than others. Long lamps would not be ideal for small storage wardrobes, but it is not hard to find another more lightweight UV lamp with much the same GPM. 

If your usable space is not sufficient for vertical implementation, check whether a UV device can be mounted either vertical, horizontally or just vertically

If Your Water Has Color

The high iron or surface sediment levels may suggest a color in your water. This can impact UV radiation from successful water infiltration so that when your watercolor seems nearly yellow, you will need to upgrade to a larger size of the UV water purifier.

The Plumbing Size

Many UV technologies are intended to attach to your plumbing, but before purchasing a product, it is always worth testing the fittings of a product. If your plumbing is not compatible to buy a UV device, the flow rate of your water will be limited.

Budget/Cost

Costs are a challenge for most of us. Just so much of it is available in our budgets. The cheapest alternative is not necessarily the best option, and the best UV water purifier is not always the most costly option. 

You will also exclude overpriced solutions and concentrate on the benefits and disadvantages of products in the budget since you recognize what you’d like to match the hourly household requirements.

Frequently Asked Questions

How can UV water sterilizers isolate the forms of microbes?

UV water purifiers normally kill any form of water-related diseases caused by bacteria, viruses, and microbes. The greatest feature of a UV water purifier is that during the filtration process it will not alter the smell or flavor of the discarded water.
