Buying a water filter or choosing a water filter. Used to suit your home and factory. If you have problems or are planning to buy water filters and water purifier, RO system, UF system (Ultra Filtration). You should know these things before you go buying.
It is a water purifier that is suitable for filtering water for family use.
This large water filter is mainly used to filter water for use such as bathing, washing dishes, washing cars, or in large quantities such as homes with large families or shops, food courts that use a lot of clean water and the most common is used for filtering tap water and ground water.
RO, officially known as Reverse Osmosis, has to go through a thorough filtration system in all 5 stages, consisting of Sediment Filter, the first filtration and may use sand filter or glass water filter, Carbon Filter to absorb paint. and odor in water, Cation Resin. Anionic resin will capture limestone in the water in the form of calcium, Membrane Filter for separating liquids with many components, and finally Post Carbon adjusts the water to be drinkable. can Filtration with this RO system can filter up to 99.99%.
UV water purification is the filtration of water by using ultraviolet light to sterilize it through the flow of water.
Water filtration with UF system. In this system, there are 4-5 steps of water filtration. It is developed after UV filter. The advantage is the convenience of filter replacement and saving in maintenance. Maintain than RO system and UV system.
Generally, water purifiers and water tanks are not warranted for their respective parts as they are related to the water conditions in each area in which they are being used. However, there will be a guarantee in the service life of the machine itself of durability for certain period of time (e.g., 1 year, 2 years or more depending on brand names etc.)
If you buy a filter tank or water filter from a company that has a storefront, then after-sales service is often included. In addition to the after-sales service, costs such as filter/water tank replacement or installation might be occurred. If anyone has studied and learned how to change the filter or water tank, this will help to save time and cost.
Today’s water filtration market is bursting with effective, high-quality purification solutions. It can be difficult to know which option is for you, especially when there are so many to choose from.
It’s wise to be aware of your choices before you make a purchasing decision, so you know for certain that you’ve made the right choice for your budget and requirements. This guide will focus on ultrafiltration, a purification process that offers a particularly impressive range of benefits.
What is ultrafiltration? It’s a membrane filtration process that sends water through a hollow fiber membrane at a high pressure.
Only water particles and a select few impurities are small enough to pass through the membrane, which consists of thousands of tiny pores. As a result, contaminants that are larger than water particles (high molecular weight solutes) are left behind on one side of the membrane, while smaller particles (low-molecular weight solutes) pass through the membrane pores to the other side.
Ultrafiltration drinking water systems are connected up to the cold water line beneath your kitchen sink. The pressure of the water promotes a good flow of water through the ultrafiltration (UF) membrane, ensuring thorough contaminant removal. This type of microfiltration system doesn’t have a tank for water storage and doesn’t produce wastewater. It usually requires its own dedicated faucet to maintain water quality on its journey into your drinking glass.
It’s easy to confuse ultrafiltration with reverse osmosis, because both water treatment methods are very similar. However, reverse osmosis offers a more thorough filtration process than ultrafiltration. Alongside the hollow fiber membrane, a reverse osmosis system also sends water through a number of filtering cartridges, including a sediment cartridge and an activated carbon filtering cartridge.
Ultrafiltration is ideal for targeting smaller contaminants that slip through most water filters, thanks to its tiny pore size of 0.1-0.01 microns. This mechanical microfiltration system can filter water all the way down to 0.025 microns.
You can utilize ultrafiltration to effectively remove bacteria and some viruses from drinking water, as well as some organic suspended solids, turbidity, and some (but only a small percentage of) natural salts and minerals.
Ultrafiltration systems have a number of industrial uses, such as in the food and beverage industry, and in the treatment of water used in factories and other manufacturing establishments. This type of water treatment can also be carried out at home.

You can purchase point-of-use ultrafiltration membranes that can be installed underneath your kitchen sink. They can be used to provide clean drinking water from your faucet, and offer a fast, simple solution compared to the majority of the water filtration methods available today.
To eliminate microorganisms from water, a chemical disinfectant is usually required. However, because the ultrafiltration membrane pore size is small enough to get rid of pathogens, it makes for an effective chemical-free alternative.
Ultrafiltration membranes have an affordable up-front price and don’t cost much to maintain. You’ll need to replace the membrane periodically, but this filtration solution typically has a lifespan of 5-7 years.
It’s hard to find many systems that are capable of removing pathogens such as bacteria. A UF membrane, however, can effectively remove these contaminants – though some viruses might remain.
Around 95% of water is used during ultrafiltration, as some water is used for backwashing the system. Because effluent water is recycled, this purification treatment is one of the more environmentally friendly options available.
Ultrafiltration membranes are relatively compact, making them less of an invasive installation in a home or for business use. They don’t typically take up too much under-sink space, though this depends on whether they’re combined with additional filtration solutions, like pre-filtering cartridges or RO units, for example.
If your water source is particularly contaminated, you might need to clean and backwash your ultrafiltration (UF) membrane frequently.
As well as cleaning and backwashing the ultrafiltration membrane, you’ll also need to replace it as recommended by the manufacturer. Failing to replace the membrane will result in the membrane being unable to do its job properly, and contaminants may not be effectively removed.
Some UF membranes come with their own pre-filter, which is used before the membrane for the removal of larger particles that could damage the screen. Having a pre-filter means you’ve got something else to maintain, and these filters need replacing frequently, too.
Perhaps the biggest setback of an ultrafiltration system is that it can’t be used to treat dissolved contaminants in water. You would require a conventional activated carbon filtering cartridge alongside the system if you wanted to treat dissolved contaminants too. Additionally, while ultrafiltration solutions can effectively remove bacteria, they may not be able to completely remove viruses.
Both reverse osmosis and ultrafiltration are two processes that use high-pressure membrane filtration technology, which is why they’re often confused with one another.
However, both processes of microfiltration have their own standout features that enable them to produce slightly different results.
Reverse osmosis is a more thorough process for a broad range of contaminant removal, eliminating more than 99.9% of contaminants during clean water production, including lead and VOCs (volatile organic compounds).
An ultrafiltration system, on the other hand, doesn’t remove dissolved solids and salts from water; only substances that are suspended (or those that float on the surface) in the water. However, what makes this filtration treatment better than the majority of water filters is that it works on a microscopic level.
You can find out more about the differences between ultrafiltration and reverse osmosis processes in our ultrafiltration vs reverse osmosis comparison guide.
There’s another type of water treatment that can remove smaller substances from water, called nanofiltration. Like ultrafiltration, nanofiltration can filter out protozoa, bacteria and viruses in water. It can also filter organic matter, salt and natural minerals.
However, nanofiltration isn’t capable of eliminating particle types that can dissolve in water. Nanofiltration typically uses a membrane with a pore size of 0.001 microns. A nanofiltration unit removes slightly more particle ions than a UF membrane, but this technology isn’t quite as capable as reverse osmosis in terms of contaminants removed.
