Distinguishing between genuine and fake RO membranes

Reverse osmosis (RO) is a highly effective water treatment technology that utilizes a semi-permeable membrane to remove impurities and contaminants from water. The RO membrane is a critical component of the system that enables the separation of dissolved solids, organic compounds, and other contaminants from the water to make it safe for drinking. Therefore, to ensure the quality of drinking water, genuine RO membranes must be used. Today, Karofi will provide some useful information about RO membranes as well as 3 effective ways to distinguish between genuine and fake RO membranes.

What is an RO membrane?

RO stands for Reverse Osmosis. The RO membrane was invented by scientist Organ in the 1950s. However, in the 1970s, it was perfected and made from Polyamide material.

The RO membrane was first applied in the field of maritime and aerospace in the United States. After discovering other uses of RO membranes, they were widely used in daily life, especially in assuring pure drinking water or providing purified water for laboratory food and pharmaceuticals.

What is the structure of the RO membrane?

The RO membrane is composed of multiple RO filter sheets that are rolled around the filter tube. Each membrane filter module consists of a clean water membrane and a reverse osmosis membrane. Finally, there is a water supply membrane. The various membranes are stacked in order, compactly, and wrapped around the central clean water recovery tube.

Between the two adjacent outer surfaces of the membrane, the reverse osmosis membrane is arranged by the manufacturer into a circle to create a water supply channel. The clean water supply channel is formed from the inner surface of the permeable membrane.

In the RO membrane heart, there is a flat membrane consisting of 3 layers: polyester fabric, 0.2 micrometer thick polyamide filter layer, and poly sulfone foam layer. The main function of the foam layer is to remove all impurities, chemicals, bacteria, and viruses from the water.

Creating a source of pure water through RO filtration technology

Thanks to its special structure, the RO membrane can remove 99.99% of harmful bacteria and viruses in water, creating a completely safe source of water without the need for boiling or distillation. Additionally, this technology also helps eliminate hazardous substances for human health in groundwater, well water, river and stream water, and contaminated water sources.

In particular, the RO membrane can also remove the carcinogenic THMs produced during the production process of Chlorine. Therefore, you can completely trust when using water directly from the water filtration machine.

Currently, RO technology is one of the most advanced and modern water filtration technologies. It produces high-quality pure water output by various stages of filters. It is considered by experts as one of the most modern and effective water filtration technologies.

3 tips to distinguish RO membrane

Due to its super filtration ability, RO membrane is an important filter in water purifiers. In fact, depending on the water source, the RO membrane can be used for 1-3 years. After this period, you need to replace the membrane for your home water purifier. Therefore, you need to know the following 3 methods to buy genuine RO membrane.

Method 1: Surface of RO membrane

When you touch the surface of the RO membrane and feel roughness, it is the genuine RO membrane. Conversely, fake membranes will be quite smooth.

Method 2: Groove line

The groove line of the genuine RO membrane is cut and glued by a machine, so it is a straight line. On the other hand, the groove line of the fake RO membrane is often "crooked", not straight, and not delicate.

Method 3: Test timeline and efficiency

This is the most effective method to distinguish between genuine and fake RO membranes. Membrane will be tested by life time, purifying capacity in an accurate method. This method is usually used by experts or big manufacturers for researching and developing new products. 

In addition, the price of the membrane is also a factor to evaluate. A cheap membrane is a used one that has been refurbished or is not genuine.

In the Karofi factory, RO membranes are tested carefully before launching and introducing them to customers. That is the reason why customers are prevented from fake, not good RO membranes.
