What Should You Know About Membrane Filter  

Membrane filters in the water filter serve the core purpose of removing contaminants. It makes the water fit for drinking and other uses. Membrane filtration not only helps the water to be safe for drinking but also improves the taste of the water. All kinds of filters use a membrane in their filtration process.

The 10000 LPH RO plant uses reverse osmosis to clean and filter all the contaminants from the water plant. The RO filter uses a semipermeable membrane that lets the water molecules pass through. What it does is block the dissolved compounds that can cause health issues. It separates these compounds and particles and bifurcates the pathways. This way, the water from the filter becomes fit for drinking.

The Components of Membrane Filters

The membranes of the filters of the water purifier service in mumbai are made of different materials. In the case of RO or reverse osmosis filters, the membranes are referred to as thin-film composite membranes. The membranes have adequate pH tolerance. Thin-film membrane filters a lot of water in a short amount of time. 

Membrane Filtration Types

Membrane filtration has four types. The type differs based on the size of the material. The contaminants are of various sizes and must be separated from the feed liquid. The four types of water filter membranes are- reverse osmosis, nanofiltration, ultrafiltration, and microfiltration. They get named in order of the increase in the pore size.

Reverse Osmosis

The reverse osmosis procedure has the tightest membrane to filter the water. It got made on the principle that only water can pass through it. That means even the tiniest of particles will not go past the membrane. 

Water has many contaminants like bacteria, spores, fats, proteins, gums, salts, sugars, and minerals. Some of these particles are harmful for consumption. The membrane ensures that they do not pass through it. 

The RO water filter cleans the water of all contaminants and improves the taste. It removes all bacteria that can make the water taste and smell bad. Thus, the water has a pleasant odour. It keeps the water fit for consumption for a long time. Also, with reverse osmosis, there is no way the particles can flow back into the filtered water.

Nano Filtration 

Nanofiltration may not be as fine a process as reverse osmosis. The water filters with nanofiltration technology allow small ions or minerals to pass through. It prohibits the larger ones. Those would include bacteria, fats, protein, gums, and sugars. 

The membranes used in no filtration are slightly more open compared to the RO ones. Only suspended solids, bacteria, and fat globules are substances that do not go through the membrane.

Ultra Filtration 

The process of ultra-filtration involves water passing through membranes with large pores. The water pressure is low. Salts, sugars, and smaller peptides can pass through.

Ultrafiltration cleans and processes potable water. The process removes the particulates the macromolecules from the water. It helps remove the bacteria from the water and gets used in wastewater treatment plants. Besides these, the ultrafiltration process gets used in the water’s desalting and solvent exchange of proteins.  

Which One Is The Best?

Out of all the filtration methods, the RO water filtration methods emerge as the winner. It is still the most preferred method to clean water. Most of the filters use this filtration method. The best and the most advanced RO filters are the most convenient and time-saving methods to clean all the contaminants from water.

The RO systems in the water filters remove all the pollutants, including lead, pesticides, fluoride, pharmaceuticals, arsenic, and other small particulate matter. With the RO filter, one can get assured that it will remove chlorine from the water. It helps to improve the taste of the water and even its appearance. The removal process is fully automated. 

Flow Rate and Pore Rate of Membrane

The filtrate flow rate passing through the membrane relates to the filter membrane’s surface properties. The pore rate refers to the volumes of all the pores in the filter membrane.

Flow and pore rates are crucial to the filter material and its design. The usual rate of the pore area in the filter membrane is 50-90%. The flow rate of the water depends on the pore rate and size.


The functionality and time-saving features of the RO water filters make them convenient enough to use. That is why so many propel prefer water RO filters. It is compact and can fit into any home space. The other ones are also quite popular. However, their popularity is more apt for industrial settings, not domestic purposes.
