What is Ultraviolet (UV) and Advantage and Disadvantage

 

What is Ultraviolet (UV)

By using ultraviolet radiation, UV technology can destroy the DNA of living organisms like cells, viruses, and spores. The dead microorganisms remain in the water but are rendered completely harmless. Ultraviolet purifiers can only kill microorganisms, they won’t help with other contaminants such as chlorine, fluoride, or inorganic materials like metals including lead. To remove those contaminants, you’d need to pair a UV water purifier with another system. UV or Ultraviolet water purifier is a proven technology that is capable to kill waterborne disease-causing microorganisms, and pathogens such as bacteria, viruses and cysts. UV lamp releases UV lamp when running water exposed to UV light, whatever germs like bacteria and viruses are damaged, inactive.

Advantages of UV water purifier

1. Low maintenance cost.

UV technology not only makes water safe to drink, but it also helps you save money on upkeep. In the water storage tank, UV lamps do not stimulate algae growth. As a result, you won't have to deal with manually cleaning the water storage tank. Change the UV lamp once in a year or when it stops working.

2. Improved water savings

When hazardous bacteria and toxins accumulate in the tank water, the tank must be emptied, resulting in water waste. However, if you use a water purifier with UV technology, you won't have to worry about this. Despite the fact that the UV lamp kills all pathogens in the water tank, the bacteria' lifeless corpses remain in the water. RO water filtration comes into play to solve this issue.

3. High purification rate

 The UV water purifier is capable to deliver 2 to 4 litres of purified water within a minute. UV water purification systems disinfect water with outstanding efficiency. It’s possible to completely disinfect water in one cycle, increasing throughput and volume treated.

4. Very less manual cleaning

If you have a UV water purifier with a storage tank, it requires cleaning twice a week, whereas without a storage tank water purifier needs almost no manual cleaning.

5. Flexible UV intensity

One of the common misconceptions of UV purification is you need a bigger system to treat water to a higher quality. This is not true. You need the correct disinfection dose (mg/cm²) which is determined by UV intensity, not system size. System size determines the flow rate.

Disadvantages of UV water purifier

1. Germs' bodies remain in purified water

UV water purifier kills waterborne disease-causing bacteria, viruses and other pathogens, but their dead bodies still remain in purified drinking water. In case of fewer germs not being exposed to UV light and remaining life or redevelop and reproduce their population and makes water impure.

2. UV Doesn’t Improve Water’s Taste

Microorganisms like bacteria and viruses might be dangerous to drink, but they don’t affect water’s taste. Using a UV water purifier, before and after purification taste and colour does not alter. If treating water has a bad smell, or odour then have to use the Activated Carbon water purifier with a combination of UV water purifiers.

3. UV Water Filtration Requires Electricity

A UV water purifier works by emitting UV light, and the UV lamp needs to be powered by an electricity supply. Although UV filtration has low operating costs and doesn’t use more electricity than a standard light bulb, installing a UV water filter will increase your energy bill slightly.

4. UV water purifier does not remove toxic chemicals. 

UV light exposure does not affect chemicals like chlorine, or fluoride. If your water contains harmful chemicals, heavy metals, volatile organic compounds, or sediment, a UV water treatment system can’t be used to remove these contaminants. That’s because ultraviolet light is only effective in treating living organisms.

5. Does not effective on turbid, mud water.

Undissolved Solids like sand, mud and other organic solid matter become an obstacle to passing UV light through the water.

UV water purifier does not purify hard water. UV water purifier designed for purifying low TDS(Total Dissolved Solids) lake, and river water.

What type of pretreatment does RO need?

Image
Reverse osmosis (RO) systems typically require some form of pretreatment in order to effectively remove impurities from the water. The type of pretreatment needed will depend on the specific contaminants present in the water, as well as the overall water quality. One of the most common forms of pretreatment for RO systems is a sediment filter, which is used to remove larger particles such as dirt, sand, and sediment from the water. This helps to protect the RO membrane from damage and prolongs its lifespan. Another common form of pretreatment is a carbon filter, which is used to remove chlorine and other dissolved gases and organic compounds from the water. Carbon filters can also remove bad taste and odor from the water, making it more palatable. A third type of pretreatment is an antiscalant that can be used to prevent mineral buildup on the membrane. This is particularly important if the water supply has high levels of minerals such as calcium and magnesium. In some cases, addition

What is RO and The Process of works

Image
  RO (Reverse Osmosis) is a blessing in the world of water purifiers. It proves to be a highly efficient process for separating pollutants and contaminants from water over a semi-permeable membrane. RO purifiers are best for water with high TDS content. So if you are staying in an area where the water supply contains a high amount of TDS, buying the RO water purifier for safe drinking water is recommended. How does the process of RO purifier works? Reverse Osmosis or RO eliminates chemical contaminants from water to make it fit for use. Combining the RO process with UV filtration in a purifier can also eliminate all biological pathogens. The marker to determine the purity of water is TDS or Total Dissolved Solids. TDS particles are ultra-minute salts or compounds that are dissolved in water. TDS particles are not eliminated through the process of simple filtration, hence RO is required. WHO mandated the level of TDS for safe drinking water is 300mg/liter. If water from your tap supply

What is RO AMC and Advantage of AMC

Image
  RO AMC stands for Reverse Osmosis (RO) Annual Maintenance Contract (AMC). It refers to a type of service contract in which a service provider or vendor agrees to maintain and repair a reverse osmosis water treatment system for a customer over a set period of time, usually one year. The purpose of the contract is to ensure that the reverse osmosis system is operating optimally and to prevent unexpected breakdowns. The advantages of having a Reverse Osmosis (RO) Annual Maintenance Contract (AMC) are: Regular Maintenance: Regular maintenance ensures that the RO system is operating optimally and prevents unexpected breakdowns. Prolonged Lifespan: Regular maintenance can extend the lifespan of the RO system, saving the cost of replacing the system. Improved Water Quality: Regular maintenance ensures that the RO system is functioning properly, which can lead to improved water quality. Cost Savings: By having an AMC, the cost of repairing a breakdown can be lower than fixing an unexpected
