Difference between uv and uf

Clean beverage methods like UV and UF in water purifiers are a requirement in today’s day and age. ‘Dirty water’ harms beyond just water-borne diseases. the important slow killers are contaminants like arsenic, lead, and other poisonous particles which will convince be fatal within the end of the day. For such times, it's best to take a position during a trusted water purifier that will remove every harmful particle and solvent, and make sure you stay healthy.

UV or Ultraviolet purifier contains a UV lamp, through which raw water passes. Due to UV candlepower waterborne disease-causing bacteria, viruses, and pathogens become inactive. Whereas UF or Ultra Filtration water purification consists semi-permeable hollow membrane with holes( about 0.01 microns wide). When raw, unpurified water by gravity, water pressure passes through the UF membrane, the bacteria, viruses are blocked in it and remains purified water.

Try our water purifier selector to settle on the right water purifier by answering simple questions without reading any buying guide.

To ignite the UV lamp, the UV water purifier requires electricity, whereas UF works supported semi-permeable membrane doesn't require electricity, uses gravity, water pressure as power.

The UV lamp is fixed in a small container sort of a pipe through which water passes. To water undergo the UV lamp it requires running water with optimum water pressure. Whereas UF water purifier uses gravity to make through the UF membrane

There has been a longstanding debate about UV vs UF purification of water systems. you'll choose either of these or a mixture like RO+UV Water Purifier. there's a difference between UV and UF technology and the way they contribute to creating water safe for consumption. To be ready to make a choice, allow us to offer you a quick about all of them.

What is UV Water Purifier?

UV Water Purifier

One of the foremost basic sorts of water filtration is often done by employing a UV water purifier, which utilizes UV radiations to kill germs. The water is forced through a tube and exposed to radiation. On the positive side, UV technology is chemical-free and straightforward to take care of. Unfortunately, it cannot eliminate TDS, nor can it eradicate the bacteria that the radiations manage to kill. The dead organisms still are present within the water that you simply eventually consume.

What is UF Water Purifier?

UF Water Purifier

The difference between UV and UF is that UF technology works with no electricity. It eradicates suspended solids, larger particles, and molecules from water through a hollow membrane. this type of water purifier can kill and eliminating bacteria and microorganisms but doesn't get obviate the dissolved solids. Unlike the RO purifier, it cannot convert water to water. it's knowing to use a UV Water Purifier, including UF filtration, for the simplest drinking experience, especially once you aren't certain of the TDS Levels within the water.

UV and UF Water Purifiers for water & TDS

To answer the question, what's TDS? And whether the UV UF water purifier features a TDS controller to melt hard water?

TDS is an amalgamation of toxic substances in water generated by industries and pesticides. The reduction of this is often essential, making it known to invest in a UV Water Purifier for a clean beverage.

Ultra Violet (UV) system

These systems work with UV rays where the germs and microbes are destroyed with the assistance of UV rays after the RO stage and provides pure and healthy water. this technique can kill harmful contaminants and may be combined with other sorts of filtration by reducing chlorine.

How does it work?

The UV water purifier makes water-borne diseases inactive by exposing them to UV rays. It uses a UV light which is mounted in such a fashion that when water passes through during a flow is exposed to UV rays, penetrate the cells of bacteria and destroy their ability to breed.

The germs are destroyed with UV rays after the RO stage and provide pure beverages.

Maintenance Costs

A quality RO gives 100% pure water that's freed from chemicals and smell, it requires low maintenance costs. While a coffee cost and quality RO compromises on filters and other accessories which need high maintenance costs.

Periodic service is a must for RO purifiers and may enjoy the best service with spare parts that keeps the RO running in perfect condition.

For a UV water purifier, UV lamps require annual replacement for better performance. After one year there's no assurance that the UV light gives sufficient disinfection. The quartz sleeve needn't get replaced but needs cleaning repeatedly during a year.

Power Consumption

If you purchase a Eureka Forbes RO purifier, its electricity consumption is negligible in comparison to other equipment. The Aquaguard purifier comes with 25 W that consumes one unit of current in 40 hours. With one unit you'll get 4800 liters of water purified. The figure may vary counting on what model and storage capacity you select.

Power Consumption for RO water purifier

While the UV unit uses an equivalent amount of energy as a 60W light bulb that creates it affordable and enhances water quality also. The UV purifiers give 30,000 MW seconds for the specified flow. The UV purifiers give optimum performance counting on model and storage capacity.

Power Consumption for UV water purifier

Family Size

Most RO’s are suitable for a family size of 1-5 members. While some high natural output water purification system recommended for both family and office is suitable for 1-15 members.

While a UV water purifier is suitable for five relations.

Who Wins the Race?

Water purifiers are essential lately for drink pure water to remain healthy. When it comes to a trusted name then you ought to choose Kent RO best water purification Company. they are available with a UV gravity water purifier that doubles the protection against impure water.

While UV water purifier has not been successful in giving 100% clean water that's why RO best water purifiers are most preferred over UV purifiers.

water can be purified by

Impure water can be purified by a process called distillation.

How does distillation works?

  • Distillation heats untreated water until the water reaches its relatively low boiling point and begins to vaporize.

  • The water’s heat is then kept at this temperature to maintain the water vaporization while stopping other elements from vaporizing.

  • This also separates the water molecules from any microscopic disease-causing organisms.

  • Once the water has vaporized, that vapor is then funneled into a condenser.

  • It flows to a container by cooling and reverting to its liquid form.

People also ask

Which is better UV or UF?

UV water purifier kills bacteria and viruses and delivers purified water, whereas UF water purifier blocks bacteria, viruses have remained in the UF hollow fiber membrane.
UV Water Purifier Does not remove dissolved solids such as arsenic, fluoride, lead. UF Water Purifier Does not removes dissolved solids.

Which is best RO or UV or UF?

RO water purifiers can remove dissolved salts and chemicals from the water. However, UV water filters are not capable of separating dissolved solids from the water. Therefore, RO systems are more effective in purifying tap water as bacteria are not the only thing contaminating the water.

What is the use of UF in water purifiers?

Ultra filtration (UF) uses standard home water pressure to push water through a semipermeable membrane and remove any contaminants. Unlike reverse osmosis, ultra filtration retains minerals in the water, while filtering out bacteria, viruses, and parasites.

What is UV UF RO?

The meaning of RO UV and UF in water purifiers are as follows: RO means Reverse Osmosis, UV means Ultra Violet and UF means Ultra Filtration. ... RO water purifiers remove everything from water, not only all bacteria, viruses, and germs, but also dissolved chemicals that could be much more dangerous than germs.
