“…Vourch et al [58] estimated that to treat 100 m 3 /d of wastewater from a dairy plant a 540 m 2 RO unit is required and that the water recovery could reach 95%. Purified water complying with drinking water criteria could be achieved by a two-stage RO + RO process treatment of dairy effluents [24,59,60,61].…”

The use of membrane technology as a processing and separation method in food industry is gaining wide application. Membrane separations can be used either as alternatives to conventional techniques or as novel technology for processing new ingredients and foods. Membrane separations are considered green technologies. In many cases, membrane processes are more advantageous than traditional technologies. For example, using cold pasteurization and sterilization with suitable membranes instead of high temperature treatment for the removal of microorganisms is more economical in terms of energy consumption. Using membrane filtration to remove microorganisms for shelf-life extension of foods instead of using additives and preservatives also create a green image for the processed foods as well as for the processing procedure. Concentration by membrane filtration instead of thermal evaporation does not employ severe heating and that it preserves the natural taste of food products and the nutritional value of heat-sensitive components. The recovery of valuable components in diluted effluents and wastewater treatment applications are among the most useful and currently active aspects of membrane technology. Pressure-driven membrane processes, namely MF, UF, NF and RO facilitate separation of components with a large range of particle sizes. It is for this reason that they find wide range of applications in food processing industry. The first part of this manuscript is to give introduction about very basic knowledge in membrane separation technology. More importantly, this review presents up-to-date commercial and potential applications of pressure-driven membrane separation processes in dairy processing industry. Keywords: Introduction Theory of membrane separationsPressure-driven membrane processes: The pressure-driven membrane processes include microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO). When a feed is introduced to a membrane separation system it is separated into retentate (sometimes called concentrate), the fraction that is retained by the membrane, and permeate (also called filtrate), the fraction that passes through the membrane. The products of interest can either be in the retentate or in permeate or in both streams. The word 'pressure-driven' means that the main driving force for separation of these processes is transmembrane pressure (TMP), which is the pressure discrepancy between retentate sides and permeate side. Generally speaking, the pore sizes (or MWCO-molecular weight cut-off in cases of NF and RO) of membranes decrease in the order from MF to RO (Figure 1). However, the separation principle is not based on the pore sizes alone. Especially in UF and NF the charge of the molecules/solutes and their affinity for the filtering membrane are also important [1]. MF is normally used for separation of suspended particles and microorganisms from soluble components in feed. UF can be applied to separate soluble macromolecules such as proteins and peptides. NF...

“…At the global level, the water supply sources costs are rising and the expenses are increased. The process of water refining and filtered to become a way to offset the reliance on water, so the water resulting from the consumption of dairy farm factory can use completely different form of the membrane used to treat liquid waste to these farms consists of a single-stage or two-stage pattern [2]. The technology used for the operations mature membrane is being used on a large scale all over the planet.…”

“…About 90% COD-rejection was observed. Balannec et al [5] implemented a dead-end filtration of dairy effluent and tested nine different nanofiltration and reverse osmosis membranes. The initial COD of 36,000 mg L -1 was reduced by 99% following membrane filtration.…”

“…Several studies compare the effectiveness of nanofiltration and reverse osmosis membranes for various wastewaters. Some of them show that the required water quality can always be achieved by membrane processes-if necessary in cascaded operation [5,8,9,11]. Since, in certain highly populated areas in Hungary biological treatment is not allowed by local authorities, the use of alternative wastewater treatment options is required.…”
