They are designed for microfiltration membrane installations for wine (turbidity of the filter FTU 0.12-0.32) of the flat-parallel type with a filtration area of 10 m2, pore size of the membrane 0.1μm, 0.45μm, with a capacity of 250 l/h and for ultrafiltration membrane installations for water (turbidity of the filter FTU 0.02-0.05) with a capacity of 500 l/h. The wine microfiltration membrane installation ensures 100% removal of microorganisms and yeast, which results in ecologically clean, crystal clear, sterile, stable, high-quality wine. Installation of ultrafiltration membrane water purification completely removes suspended particles, colloids, bacteria, microorganisms, viruses, proteins, large organic compounds, microbiological residues and partially chemical components, including hardness salts, from water. Sterile drinking water (bottled water) is produced. Microfiltration and ultrafiltration membrane installations can be used by companies for the production of wine and drinking water, such as “family wineries” and “chateau”-type enterprises. Micro- and ultrafiltration membranes and equipment have a low cost, which significantly reduces the costs of wine and drinking water production.

Drought is a major problem for plant breeding in the country during dry years. This, in parallel with the increase in the technical capabilities of agriculture, has put more emphasis on overcoming the drought phenomenon. For this purpose, efforts have been made both in the development of relevant technical concepts and in the development of appropriate methodologies and technologies. The most important activity in this direction is the redistribution of water resources mostly over time. The report presents some aspects of overcoming the effects of drought by optimizing the use of water resources.

The article describe the design and operation of a prototype of satellite pump and a prototype of satellite motor. In both machines, the operating mechanism consists of a non-circular gear with external teeth (rotor), non-circular gear with internal teeth (curvature), and ten gear wheels which cooperate with the rotor and the curvature. The differences between the commutation unit in the pump and the commutation unit in the motor are described. The principle of axial clearances compensation in the pump and in the motor is also presents. The article contains the values of the losses and the efficiency of these machines supplied with rapeseed oil, HFA-E emulsion and pure tap water. The results of durability tests of motor supplied with HFA-E emulsion and rapeseed oil are also presented.

The purpose of this work was to determine quantitative indicators and assess the quality of water of ponds located in the central part of the cities of Aktanysh, Leninogorsk and Bugulma of the Republic of Tatarstan of the Russian Federation by phytoplankton organisms. Phytoplankton samples were taken in June 2016, 10 stations were selected from each reservoir – coastal and deepwater, confined to different habitats.

Against the background of ongoing eutrophication of the Baltic Sea, this study examined drivers and constraints for implementation by farmers of measures to minimise nutrient losses to waters. The research was conducted in two Polish regions (Mazovia and Pomerania) and included 28 agricultural farms. Four remediation tools were tested and the results evaluated. The study clearly demonstrates the need for greater awareness among farmers of nutrient flows and management on their farms, especially in a changing world requiring them to be better prepared to show flexibility in their production.
