“…These results show that the specific flux values of the chitosan ultrafiltration membranes for whey are consistent with similar experimental data on whey ultrafiltration using membranes made from another polymer [21]. Figure 5 illustrates the dependence of the rejection factor of whey proteins on the filtration pressure for chitosan ultrafiltration membranes.…”

Chitosan pressure-driven filtration membranes have been studied. The factors affecting the solubility of high-molecular-weight chitosan have been analyzed, and the optimal procedure for preparing its concentrated solutions has been proposed. Formulations of casting solutions for fabricating micro-, ultra-, and nanofiltration and reverse osmosis membranes based on chitosan have been developed. The membranes obtained using the dry and dry/wet casting techniques have been tested to determine their porosity, specific flux, and rejection ability. It has been established that the performance characteristics of the developed chitosan membranes are similar to those of pressure-driven filtration membranes made from other polymers.

In Russia, as well as all over the world, one of the most acute problems is the protection of natural water resources from sewage contamination of food, especially dairy processing enterprises. However, despite the fact that restrictions, fines and suspension of their activities have been established at the legislative level for exceeding the established standards for the discharge of pollutants into reservoirs, they continue to cause more and more significant harm to the environment. The main objective reason for this phenomenon should be attributed to the lack of an effective technology for cleaning complex in composition, with changing even during the day physico-chemical properties of effluents of milk processing enterprises. The purpose of the study was to develop the concept of deep processing of secondary dairy raw materials for subsequent use in industrial production. The paper presents an analysis of the basic structure of the modern technology of wastewater treatment of dairy processing enterprises at factory treatment facilities and suggests the basic principles of processing secondary dairy raw materials. The analysis of the presented data shows that modern methods of wastewater treatment used in most dairy plants do not meet the standards. Following the proposed principles will ensure favorable conditions for the release of lactose from secondary dairy raw materials at subsequent stages of its deep processing. One or another combination of these processes primarily depends on the cost of technologies and the equipment necessary for their implementation, the volume of raw materials, the required depth of its processing, as well as the market price of finished products.

“…It is also, considered an effective method for treating generated water and oily wastewater treatment. The key benefits of using it are its effectiveness in removing oil, lack of need for chemical additives, low energy cost, ability to function at low trans membrane pressures of 1 to 30 psi, and little space requirements [24,25].…”

Wastewater treatment is a continuous environmental problem, which troubles human activities. Numerous efforts have been made over the years to develop newly efficient technologies, including traditional filtration, coagulation-flocculation, and biological treatment systems. Among which, membrane technology is proven to be a significant one. Membranes technology is divided into four categories based on pore size. The four types of membrane technology including micro-filtration, ultra-filtration, nano-filtration, and reverse osmosis. This paper focus on the introduction, advantages, disadvantages and protection of these four membrane processes.
