Ultrafiltration or Reverse Osmosis? Choose the Best Purifier for You!

Ultrafiltration System and Reverse Osmosis System is two most efficient water filtration processes available, commonly referred as RO and UF. Though both own an outstanding filtration properties, they may have some differences on various facets. To learn more knowledge about the two systems will help you choose the right one.

What is Ultrafiltration System?

Ultrafiltration is a membrane separation process based on the principle of sieve separation and driven by pressure. The filtration accuracy is within the range of 0.005-0.01μm, which can effectively remove particles, colloid, bacteria, heat sources and polymer organic substances in water. This technology can be widely used in the separation, concentration and purification of substances, and has played an increasingly important role in reverse osmosis pretreatment, drinking water treatment, water reuse and other fields.

What is Reverse Osmosis System?

Reverse osmosis system is an advanced method of water purification. It is a membrane filtration technology that works by forcing water under pressure to permeate very tiny holes in the semi-permeable membrane. Modern reverse osmosis devices for homes combine membrane technology with carbon and mechanical filtration to produce highly purified, excellent tasting water.
Differences between Ultrafiltration and Reverse Osmosis System

Filtration accuracy and substances they filter out

Besdor BUF1 Ultrafiltration Filter System and Besdor AWater1 Reverse Osmosis Filter System, for example, differ in filtration accuracy and the substances they filter out. Besdor UF System has the filtration accuracy of 0.01 micron, which could effectively remove colloid, suspended solids and more impurity and absorb the smell and taste in water. On the other hand, Besdor RO System has the filtration accuracy of 0.0001 micron, which could remove 99.99% of pollutants, including fluoride, chlorine, scale, TDS, lead, mercury and other heavy metals.

Storage for water

In terms of water storage, there is a certain difference between the two systems. A large part of the RO system on the market is designed with a tank. This design will take up more space in the kitchen, but there are also RO system with a tankless design, like Besdor AWater1 RO system, which could save much space for you. The UF system usually does not need a water storage tank, such as Besdor's UF system, which could save 70% of the kitchen space.

Cost for the systems

In general, the cost of the RO system itself is slightly higher than that of the UF system. The RO system on the market generally costs 200-400 dollars, while the ultrafiltration system generally costs 150-200 dollars. The two systems of Besdor are in this range, and the price is relatively moderate, suitable for most people to buy.

Installation

In general, RO systems take a little longer to install than UF systems, for more connections need to be made for the system to operate correctly. While installing an ultrafiltration unit is very simple, you could just connect the feed supply and the other end of the filter, and then connect directly to the dedicated faucet. For example, Bersdor RO System takes 30 minutes to install, while Besdor UF System takes only 10 minutes to install.
