Ultrafiltration and reverse osmosis are counted as the most effective and the most powerful systems of filtration used for the purification of water. Though both the systems are used for purification of water and both of them are known for working on the basis of the best filtration properties, but if we get into the details of the techniques and also in the details of the workings of the properties of both the systems then there are some of the notable differences between them. Ultrafiltration and reverse osmosis being the most popular systems used for the water filtration often put the people into confusion as both these systems work on a slightly different set of features, properties, and also techniques. So here we will clear the air of all the confusions and would discuss in detail one after the other all the differences that are associated with the ultrafiltration and reverse osmosis system of filtration.


iven below are the differentiating points about the Ultrafiltration Plant as well as the plant that works on the basis of reverse osmosis: Membrane technology: First of all let us discuss the difference between the two membrane technologies that are used in the ultrafiltration and the reverse osmosis plants. Though both of them use membrane technology, both of them use it in different manners. The reverse osmosis based plant uses the semipermeable membrane this type of membrane is capable of removing 95 to 98 % of inorganic matter from the molecules of water. On the other hand, the ultrafiltration plant uses the hollow fiber membrane for the removal of solids and microscopic contaminations. Elimination policy: Now if we differentiate between the ultrafiltration plant and the reverse osmosis plant then we can say that the reverse osmosis technology is best for the elimination of dissolved minerals from the water whereas an ultrafiltration plant will not work on the elimination of minerals from the water, the ultrafiltration technology works on the removal of only the solid matter and the microscopic matter from the water. Installation: If we differentiate between the ultrafiltration and reverse osmosis plants on the basis of installation then we can say that reverse osmosis might appear tricky for installation also after installation in case of reverse osmosis more connections need to be established for proper operations of the machine.


On the other hand, the unit based on Ultrafiltration is very easy to be installed and is also very easy to be connected for further operations therefore for the ease of installation and operations ultrafiltration has an advantage over reverse osmosis. Cost: Now if we talk about the cost difference then that is something totally opposite to each other in case of reverse osmosis and ultrafiltration. The reverse osmosis would be expensive at the initial but would become budget-friendly at the time of further maintenance but ultrafiltration would be cheaper initially but would be expensive to be maintained further. Other than the differences given above there are few more difference between the reverse osmosis and ultrafiltration system those differences, are as follows: Reverse osmosis works with slow filters whereas ultrafiltration works with a great speed of filtering one gallon of water every minute. Reverse osmosis produces a lot of wastewater on the other hand ultrafiltration doesn’t produce any wastewater. Reverse osmosis works on high pressure whereas ultrafiltration doesn’t need much pressure and it works very smoothly. So, now all the major and minor differences related to the reverse osmosis and the Ultrafiltration Water Treatment have been discussed in detail, so after reading it carefully for once there would be no doubt left in anyone’s mind
