Basic principles of membrane technology  Advantages of membrane technologies in the food and beverage industry  Membrane types used in the food and beverage industry and industrial scale applications Membrane technologies are widely used in the food and beverage industry, especially in the production and processing of milk and dairy products, fruit juices and alcoholic beverages.Figure A. Basic scheme of a membrane process.Purpose: This review article includes detailed information about the advantages of membrane technologies used in the food and beverage industry compared to traditional methods, the basic principles of membrane technologies, membrane types, common application areas, and studies reported in the literature. Theory and Methods:The uses of (i) membrane separation, (ii) evaporation and (iii) freeze-concentration techniques are investigated for purification, separation and concentrated product preparation in the food and beverage industry. Results:Membrane processes are a more advantageous method than traditional methods to obtain high quality and cost-effective products in the food and beverage industry. Conclusion:The application of membrane processes as an alternative to traditional separation, purification, and concentrated product methods for "sustainable production" and "zero waste approach" in the food and beverage industry is a very popular and growing subject. Pressure-driven membrane processes, namely MF, UF, NF, and RO, lead to effective separation of components with a large range of particle sizes. Hence, this paves the way to find a wide range of membrane applications in the food and beverage industry. In addition, since membrane processes are more economical in terms of energy consumption compared to traditional techniques, it is predicted that their use will have an increasing trend.

“…Its wide range of applications in water treatment processes is a result of its effectiveness and ease of use. Using this process, numerous experiments have been conducted to maximize the removal of pollutants [15] such as TSS, TN, TOC, natural organic matter, etc. This process could account for approximately 90% of the removal of pollutants in raw water [16].…”

Many coagulants such as aluminium sulfate, ferric sulfate, and ferrous sulfate have been investigated in the past, but there is a lack of data on their effectiveness to some specific water quality parameters. This study aimed at investigating the efficiency of the coagulation water treatment process to remove pollutants such as total organic carbon (TOC), total nitrogen (TN), and total suspended solids (TSS) from urban drinking water. The polyaluminium chloride (PAC) coagulant was applied to determine the impact of the treatment process on the structure and diversity of these pollutants in urban drinking water. All water samples were collected from the Yangtze River, Baoshan district, Shanghai, China, over a period of three months which coincided with the late summer and early winter periods. Specific to different coagulant characterizations, a preliminary test was performed with three other coagulants, namely, aluminium sulfate, polyaluminium, silicate sulfate, and ferric sulfate to determine their optimal conditions for floc characterization and removal efficiencies. In summary, the overall performance of the PAC coagulant was better than that of the other three coagulants used in the pre-treatment of the sampled water. The obtained results revealed that under the optimum operating conditions, the doses of the PAC were as follows: 20, 35, 50, 65, and 80 mgL−1, respectively. The water temperature and pH were determined by using a pH meter, the TOC and TN determined by using a TOC analyzer, and the TSS by following the ASTM D2540 method. Furthermore, the response surface methodology by the Box–Behnken optimization analysis was applied to coagulant dosage, temperature, pH, and three corresponding dependent factors (TSS, TOC, and TN) to determine the best optimal conditions for the PAC performance. To determine whether or not the quadratic model adequately explained and predicted the response during the coagulation process, an analysis of variance was performed. Multiple optimal factors were identified for the urban drinking water treatment, including a pH value of 6.9, water temperature of 20.1 °C, and a coagulant dosage of 9.7 mgL−1.
