What is Membrane Filtration?
At its most basic level, membrane filtration involves separating a single flow into two streams, one more concentrated than the other, by using pressure to selectively pass material through a semi-permeable physical barrier a membrane. The separate streams can then either undergo further processing, or, in the case of a waste stream, be channeled for recycling or to an appropriate outlet. With the correct membrane selection, the filtration process can isolate dissolved species of specific sizes while allowing other dissolved components to permeate through the membrane. The membrane filtration spectrum starts at the smallest molecular level with reverse osmosis a process that allows the finest degree of separation. More dissolved species will pass through a membrane as you move through the filtration range from dewatering or water purification with very tight reverse osmosis, through nanofiltration, ultrafiltration, and finally microfiltration, which is essentially a separation of submi
Membrane filtration is a technique which is used to separate particles from a liquid for the purpose of purifying it. This filtration method has a number of applications, ranging from treating wastewater to filtering milk used for cheese production, and there are several different approaches to membrane filtration. In all cases, the goal is to create a filtered solute. A number of different types of systems are available from companies which specialize in filtration products, along with replacement membranes and other parts and equipment. In membrane filtration, a solute is passed through a semi-permeable membrane. The membrane’s permeability is determined by the size of the pores in the membrane, and it will act as a barrier to particles which are larger than the pores, while the rest of the solute can pass freely through the membrane. The result is a cleaned and filtered fluid on one side of the membrane, with the contaminated solute on the other side. Nanofiltration, ultrafiltration
Membrane Filtration Technology is a proven separation method used on molecular and ionic levels. Over the past 30 years this technique was primarily adapted for the Dairy industry. However, the technology is now widely used across most Food & Beverage Sectors, as well as Industrial applications e.g. • Dairy – Whole Milk, Skim Milk, Sweet/Acid Whey, Permeate, etc. • Brewing & Beverage – Beer, Wine, Juice, etc. • Pharmaceutical – Enzyme production. • Municipal Water purification, Ground Water, etc. • Separation of paint and water in the automotive industry. • Treatment of dialysis equipment to purify blood JohnsonDiversey’s Divos product portfolio, cleaning procedures and application expertise deliver superior results, increasing performance and processing efficiency for all membrane installations (MF, UF, NF, RO, Electrodialysis), in the food, beverage and pharmaceutical industries.
