WebBack pressure regulators are commonly used in membrane separation and membrane filtration processes to carefully control both the permeate pressure and retentate pressure. Depending on the osmotic pressure of the chemistry involved, the differential pressure across the membrane (transmembrane pressure) must be carefully maintained in a … WebJul 1, 2014 · The feed gas is divided into two streams, namely permeate and retentate, usually separated by a selective membrane [29] [30]. The driving force for the permeate is also achieved by the difference ...
WebFrom the optimization, it was discovered that the maximum hydrogen purity and recovery in the permeate were 99.99% and 53.89%, respectively. For maximum carbon dioxide purity and recovery in retentate, 18.06% and 99.80%, respectively were … In the paper mill industry, the retentate (non-biodegradable organic material) is incinerated to recover energy and permeate (purified water) is discharged into waterways. It is essential for the permeate water to be pH balanced and cooled to avoid thermal pollution of waterways and altering its pH. See more Ultrafiltration (UF) is a variety of membrane filtration in which forces such as pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high See more The basic operating principle of ultrafiltration uses a pressure induced separation of solutes from a solvent through a semi permeable membrane. The relationship … See more Depending on the shape and material of the membrane, different modules can be used for ultrafiltration process. Commercially available designs in ultrafiltration modules vary according to the required hydrodynamic and economic constraints as well … See more In order to increase the life-cycle of membrane filtration systems, energy efficient membranes are being developed in membrane … See more Industries such as chemical and pharmaceutical manufacturing, food and beverage processing, and waste water treatment, employ ultrafiltration in order to recycle flow or add value to later products. Blood dialysis also utilizes ultrafiltration. Drinking water See more Concentration polarization When filtration occurs the local concentration of rejected material at the membrane surface increases and can become saturated. In UF, increased ion concentration can develop an osmotic pressure on … See more When designing a new membrane separation facility or considering its integration into an existing plant, there are many factors which must be considered.
