Aim. Consideration of the membrane technology process – reverse osmosis – by directed and controlled processing of whey and its filtrates through special semipermeable partitions (filter membranes) with a pore size from 0.1 to 1.0 nm, carried out at a pressure of 3.0 - 10.0 MPa with the release of particles (cutting off) with a molecular weight of 100 Daltons. Reverse osmosis allows you to concentrate all the compounds of whey and filtrates, separating almost distilled water (condensate). Discussion. In the molecular sieve separation system, reverse osmosis logically continues the membrane treatment of filtrates (permeates) of native, as well as separated whey and their microfiltrates, ultrafiltrates, nanofiltrates and diafiltrates. In principle, the reverse osmosis process should be implemented to pre-concentrate the whey, which will eliminate its loss (draining) and expand the range of use. OO is promising for processing salted whey with the removal of unwanted sodium chloride, as well as for cleaning the condensate of evaporation plants from the components of dairy raw materials that come with foam and secondary steam. Conclusion. In general, for the dairy industry of the food industry of the agro-industrial complex, reverse osmotic treatment is necessary for the implementation of a closed production cycle with a recycled water supply.

The formation of N-nitrosodimethylamine (NDMA) is of major concern among wastewater recycling utilities practicing disinfection with chloramines. The NDMA formation potential (FP) test is a simple and straightforward method to evaluate NDMA precursor concentrations in waters. In this paper we show the NDMA FP results of a range of tertiary wastewater treatment plants that are also the source for production of recycled water using an Ultrafiltration – Reverse Osmosis (UF-RO) membrane process. The results indicate that the NDMA FP of different source waters range from 350 to 1020±20 ng/L. The fate of these NDMA precursors was also studied across the different stages of two Advanced Water Treatment Plants (AWTP) producing recycled water. These results show that more than 98.5±0.5% of NDMA precursors are effectively removed by the Reverse Osmosis (RO) membranes used at the AWTPs. This drastically reduces any potential for re-formation of NDMA after the RO stage even if chloramines may be present (or added) there.

Agriculture is the most important area of economic activity for the production of products and services in order to provide the population with quality food, industry with raw materials and promote sustainable development of rural areas. In recent years, there has been a downward trend in the rate of agricultural development, which is lagging behind the growth rate of the Russian economy as a whole. Structural changes in the agro-industrial complex have not produced significant positive results, which is caused by a number of reasons. One of the directions of agricultural policy in Russia is the accelerated development of animal husbandry and increasing the competitiveness of domestic livestock products in the domestic market. The state program for the development of agriculture and regulation of markets for agricultural products, raw materials and food provides for a set of measures for the priority development of animal husbandry. Implementation of these measures requires improved management in order to increase the efficiency of livestock production. The article considers aspects of the formation of accounting and analytical support for management of the livestock industry, economic and statistical analysis of trends and structural changes in the livestock industry. The best practices of Russian scientists in the field of accounting and agricultural Economics are summarized

In the farms of the north-eastern slope of the Greater Caucasus wood raw material obtained from intermediate felling, is not fully utilized and is not effective, due to the organizational and technical difficulties of farms. In addressing these issues in 8 directions of the region with a length of 40-50 km 14 intermediate assembly points were organized, which are intended for the collection and temporary storage of wood raw material harvested within a radius of 15-20 km of the forest. Need to establish assembly points is due to the complexity of relief items and the possibility of year-round use of the main roads of regional importance. To ensure uninterrupted timber industry and in full at the assembly point accumulated wood raw material is partially sorted. Processing of harvested wood raw material is planned for timber industry, located near the central region of the main road in the territory of Cuba town. Establishment in the area of the complex is considered justified, since the resource base in the coming years for intermediate, and later for the main use will be more than 100 thousand hectares of forests in the region. In the proposed area for the industrial complex for processing of raw wood there are all the technical and economic prerequisites. Accumulated in the assembly points wood raw material to the point of processing is transported using self-loading lumber carriers of up to 8 meters length, which is associated with a complex terrain conditions and road network in the region. This complex is planned to organize the following process areas: sawmills, parquet and packaging, small-chip technology, processing of technical greenery. In organizing the production sites size and quality characteristics and volumes of each category of harvested wood raw materials are taking into account, as well as the need for forest products in the region and the country as a whole. In the processes it is envisaged to use the most advanced modular processing of wood with the release of standard lumber, wood workpieces of different products, pulp chips, wood greens and products of its processing.

Zinc scrap is a source of raw material for zinc oxide production. However, to qualify the requirement of raw material for zinc oxide (99.5%) production, refining this source is needed. Many methods are considered such as rectification, chemical method, etc., but difficult to apply on an industrial scale. This workfocused on the investigation of the influence of temperature and time factors for asessing the possibility of applying liquation method for the purification of impurities from scrap zinc.The experiment results show that the optimum temperature of liquation to remove Pb,Fe from zinc scrap is in the range of 440-450°C, the optimal time of the process is 8h for the pot with 8cm in height and 6cm in diameter (the quantity of raw zinc sample is about 2kg / batch), then we can obtain about 80% of zinc metal with an average Zn content of about 97, 0%, both Pb and Fe content decreased to a range from 0.35 to 0.4%, and 1.0 to 1.1%, respectively, which meet the requirement of raw materials for the production of high quanlity ZnO ( 99,5 %). Based on the parameters obtained on lab-scale, a trial on pilot scale of 250 kg / batch was conducted, The result confirms that the quality of the products meets the requirement of raw materials for production of high quality ZnO (99.5%) and a technology process for refining zinc scrap by the liquation was proposed.

The article examines the essence of foreign economic activity of enterprises, the features and prospects of its implementation in the field of agrarian and industrial complex. Based on the conducted analysis, it is proved that agrarian export of Ukraine plays a significant role in the formation of the budget and GDP of the country, since its share in 2018 was 14.2% of GDP and 33.4% of the total national exports of goods. The dynamics of export-import operations of the agrarian sector is explored and it is found that it demonstrates a positive trend in contrast to the general foreign trade balance of Ukraine. The analysis of the agrarian exports structure in 2010-2019 confirms the growth of the share of the majority of agrarian products types sold abroad. However, Ukrainian exports are mainly oriented towards raw materials, which, among other reasons, is associated with technological backwardness and the limited ability of domestic agricultural producers to purchase modern equipment and technologies due to theirs low solvency. The commodity orientation of Ukrainian exports makes the competitive position of Ukraine in foreign markets vulnerable, since the demand for commodities is unstable and is characterized by significant price volatility. The geographical structure of foreign trade in agrarian products and the possibilities of its further diversification are investigated. The majority of Ukrainian products in Europe are purchased in Poland, Italy and Germany. Significant connoisseurs of Ukrainian products are also Turkey, China, India, Egypt. Ukrainian exports should be expanded to Asian and Eastern countries. The key problems that put the brakes on the development of the foreign economic activity of the enterprises of agrarian and industrial complex and hinder the competitiveness increase of domestic agrarian products in the international market are identified. A number of measures are proposed to promote the further development of the foreign economic activity of the enterprises of agrarian and industrial complex, including the development of appropriate strategies taking into account global market trends, harmonization and compliance with the quality and safety standards of agrarian products, improving the innovative component, strengthening state support (including financial) of the export-oriented agrarian enterprises, improving the investment climate, and more.

The article analyzes the approaches to the interpretation of the concept of differentiation. The own interpretation of the concept of differentiation of development of branches as process of development of the enterprises on indicators of efficiency of use of actives, own capital, labor resources, efficiency of manufacture and possibility of creation of new kinds of production is offered. The components of the processing industry of the agro-industrial complex of Vinnytsia region are studied and the main ones are determined. The main factors influencing the development of differentiation of enterprises of the processing industry of the agricultural sector are analyzed. The analysis on the basic financial indicators of activity of the processing enterprises of agrarian sector of Vinnytsia region depending on the size of the organizations is carried out. Prospects for the privatization of distilleries in Ukraine are highlighted. The possibility of product differentiation at the enterprises of agro-industrial complex processing with orientation on creation of new productions is substantiated. The low level of management of distilleries was confirmed and the prospects of privatization of these organizations in accordance with the current legislation were outlined. It is determined that the main promising area of sectoral differentiation of the processing industry of the agro-industrial complex is the formation of sugar, meat processing, agricultural and alcohol industries on the basis of raw materials - production of biofuels (biogas, bioethanol). These studies show that the developed areas of differentiation of processing enterprises will avoid the practice of concealing profits at enterprises, increase revenues to the state budget from the alcohol industry; achieve growth in foreign investment. Improving the management of enterprises in the agro-industrial processing industry will contribute to the growth of the gross regional product and the profitability of production in the processing sectors of the agricultural sector. This will increase the energy independence of the region, reduce energy costs of distilleries, improve the environmental condition of water resources in the region, reduce greenhouse gas emissions and provide the livestock industry with protein feed.

Abstract The distinguishing feature of the proposed flow method before the classical (chamber) method is that the entire production cycle of natural phosphate processing is carried out in two stages. At the first stage, the phosphorite is treated with a stoichiometric flow rate of concentrated sulphuric acid (at least 93%), under conditions of complete decomposition of phosphorite to form phosphoric acid and crystals of anhydrite (calcium sulfate). The reaction temperature is 122 °C. In the second stage, the resulting concentrated solution of phosphoric acid in a mixture with sulphur is involved in a reaction with an additional input of phosphorite, which is the basis for the mechanism of chemical formation of monocalciumphosphate and granulation of superphosphate mass. The processes for neutralizing phosphoric acid on monocalciumphosphate and for granulating the product by coagulation are combined in one apparatus. The drying stage of the product is excluded from the scheme.

Permanent crises in the Ukrainian economy, the devaluation of the hryvnia, decline in household income and purchasing power, increased competition in the global market, as well as the continuous rise in world prices for food and non-food items have created new realities for enterprise functioning in the dairy subcomplex of Ukrainian agro-industrial complex and cause its transformation. World milk production and consumption are increasing. However, there are opposite trends in Ukraine: in 1990, the country produced 24.5 million tons of milk and was the 6th in the world ranking of milk producing countries, in 2020 – 9.3 million tons and the 22nd place, respectively. Therefore, the study of the reasons for the existence of these trends is very relevant. The research was based on the following methods: qualitative analysis and synthesis, economic and statistical analysis, comparisons, analytical and logical generalizations, etc. At the beginning of 2021, the total number of cattle in Ukraine amounted to 2.874 million and over the past 10 years, this number has decreased by 1.952 million, including cows – by 0.958 million. Milk production remains a small-scale branch. In 2020, 9.263 million tons of milk were produced (17.66% less than in 2010). Of these, 29.8% – in agricultural enterprises and 70.2% – in private households. However, the sanitary quality control of milk is carried out only in 14.8% of private households, therefore, in 2020, the main milk supplier for processing were agricultural enterprises, which supplied 77.2% of the total amount of milk delivered for processing, thus ensuring an increase in quality and safety of milk obtained by processing enterprises. A significant reduction in the volume of milk supplies for processing led to a decrease in the number of processing enterprises by 69.14% in 2020 compared to 1990. The main factors of transformation of the dairy subcomplex of Ukraine include declining cow population, insufficient quality of raw milk and its non-compliance with the EU regulations and standards, low technological level of milk production, insufficient quality control of raw materials, lack of modern equipment, high capital and labor intensity of production processes, rising prices for energy and other resources, lower consumption of dairy products due to low purchasing ability, increased competition in global and domestic dairy markets, etc. Possible directions of small-scale milk producers’ integration need further research.

Батыс Қазақстан облысындағы кәсіпорындардың эволюциясы экономикалық дамудың жалпы циклдік сипатына байланысты да, әр түрлі сыртқы және ішкі факторлардың осы салаға әсер етуінен, сондай-ақ даму процесінде сөзсіз ауытқулар салдарынан ауытқуларға ұшырайды. Батыс Қазақстан облысының аймақтық агроөнеркәсіптік кешенін тұрақты дамытудың басымдықтары талдау арқылы анықталуы керек. Зерттеудің мақсаты - Батыс Қазақстан облысының агроөнеркәсіптік кешенінің тиімді және тұрақты дамуын зерттеу болып табылады. Бұл тақырыпты зерттеу кезінде статистикалық-экономикалық әдіс, талдау және синтез қолданылды. Ауылшаруашылық кешенінің жеке аймақ ретінде тұрақты дамуы да, жалпы елдің де дамуы ауылшаруашылық кешенінің тұрақты қалыптасуынсыз мүмкін емес, себебі оның түпкі өнімі қайта өңдеу өнеркәсібі болып табылады, ал оның мақсаты - талаптарына сай халықты сапалы өніммен қамтамасыз ету. Талдау көрсеткендей, ауылшаруашылық өндірісінің қазіргі жағдайы, қолайсыз факторлардың әсерінің күшеюімен сипатталады, ең алдымен табиғи факторлардың өндірісінде, жалпы өсімдік шаруашылығы өнімінің жылдық айырмашылықтарын тудырады, және өз кезегінде мал шаруашылығындағы ауытқуларға әкеледі, сонымен қатар оның әсері өңдеуші салаларда сезіледі, ал бұл өнеркәсіптің шикізаты болып табылады. Зертеу барысында 2015 жылдан бастап Батыс Қазақстан облысының аумағында ауыл шаруашылығы өнімдері өндірісінің күрт төмендегені анықталды, бұл жалпы, сондай-ақ өсімдік шаруашылығы мен мал шаруашылығы салалары бойынша да өндіріс тұрақтылығының төмендеуіне әкелді, және ол бүгінгі күнге дейін жалғасуда. Агроөнеркәсіптік кешеннің шикізат саласындағы өндіріс тұрақтылығының төмендеуі қайта өңдеу өнеркәсібі өнімдерін өндіруде ауытқулардың артуына әкеліп соқтырды, бұның нәтижесінде халыққа азық-түлік өнімдерін ұсынуда тұрақсыздық пайда болды. Батыс Қазақстан облысының АӨК-ін оның салаларының өнімділігі мен кірістілігін арттыруға бағытталған одан әрі дамыту өндірісті жаңғыртуды және қайта жарақтандыруды, оның инфрақұрылымын дамытуды және салалық кластерлерді қалыптастыруды талап етеді.

The evolution of enterprise in the West Kazakhstan region is subject to fluctuations due to both the general cyclical nature of economic development and the impact of various external and internal factors on this industry, as also fluctuations unavoidable in the evolution process. The priorities for sustainable evolution of the regional agro-industrial complex of the West Kazakhstan region should be identified through analysis. The goal of the research is to study the effective and sustainable development of the agro-industrial complex of the West Kazakhstan region. Through studies this topic, the statistical-economic method, analysis and synthesis were used. Sustainable development of the agro-industrial complex of both a particular region and the country as a whole is impossible without the stable functioning of its core - agriculture, the final product of which is used by the processing industry, whose goal is to provide the population with high-quality products in volumes that meet their requirements. Current state of agricultural production, as the analysis shows, is characterized by an increase in the influence of unfavorable factors on production, first of all natural ones, which cause annual differences in the production of gross crop production, which, in turn, convey fluctuations to the livestock industry and, as a result, affects the processing industries. it is the raw material of the industry. In the course of the study, it was found that, since 2015, in the territory of the West Kazakhstan region, there has been a sharp decline in agricultural production, which led to a decrease in the stability of production in general, and in the fields of crop and livestock production, which continues to the present. A decrease in the sustainability of production in the raw materials sector of the agro-industrial complex entailed an increase in fluctuations in the production of products of the processing industry, which ultimately resulted in the emergence of an instability in the supply of food to the population. Further development of the agro-industrial complex of the West Kazakhstan region, aimed at increasing the productivity and profitability of its industries, requires the modernization and re-equipment of production, the development of its infrastructure and the formation of industry clusters.

Interest in reuse of process water from the food industry has reinforced the importance of controlling and monitoring the effectiveness and reliability of treatment systems regarding removal of organic matter and microorganisms. The ability of adenosine triphosphate bioluminescence, conductivity, turbidometry, absorbance, and multichannel fluorescence spectroscopy for indirectly monitoring the integrity of a reverse osmosis membrane when treating process water recovered from peeling in a shrimp processing line was evaluated. This study demonstrated that reverse osmosis was capable of removing bacteria (ca. 7 log CFU ml−1) to the levels required by the regulatory authorities for water recycling within the same food unit operation. Adenosine triphosphate and turbidometry showed a higher sensitivity for detecting compromising conditions at the treatment system (0.1% concentration of feed in permeate) and a better correlation with the aerobic count at lower levels than the other methods investigated. The sensitivity for assessing membrane integrity of conductivity and multichannel fluorescence was 1% of feed in permeate. Impact of feed variations was best leveled out in the permeates for turbidity measurements. Multichannel fluorescence spectroscopy may require laborious calibration procedures and expertise regarding data analysis and interpretation of results, which are not always available in food industries. Absorbance did not respond to changes in membrane integrity and was not well correlated to the aerobic count because of the poor sensitivity of this method for these purposes.
