Water filter with central perforated pipe for livestock complexes

Abstract

Improving the livestock sector is a priority for the development of agricultural production in the Russian Federation. The development of animal husbandry to a certain extent depends on the use of clean drinking water. The use of contaminated drinking water for animals and birds leads to the accumulation of harmful and toxic substances in meat, milk and eggs. The use of such products by people significantly affects their health, leads to various diseases and shortens life expectancy. To filter water from various impurities, slotted filters are used in livestock complexes that do not provide high-quality water purification. A prototype of a filter for water purification with a central perforated pipe with a productivity of 5 m3/h with an increased service life of the filter bag has been developed. The developed filter provides water purification from high concentration of salts of iron, manganese, chlorine, hardness salts, hydrogen sulfide, pesticides, and also various organic compounds. The purified water is clean and transparent, has a pleasant taste, contains the optimal chemical composition of various impurities, does not contain pathogens and helminth eggs, and therefore meets the high sanitary and hygienic requirements for the safe drinking water for farm animals in the water treatment line of the livestock complex. It can also be used in chemical water treatment units of thermal power plants and other organizations.

Regulation of the germination energy of potatoes by with low energy treatments

“…The studies were carried out in accordance with the plan of the Box-Behnken four-factor second-order experiment [12][13][14], where the response function is the average time of emergence of all shoots Y 1 (t, days), the number of awakened eyes Y 2 (n, pieces), the length of shoots to the end of the research Y 3 (l, mm) after 15 days from the beginning of the experiment [15]. As the factors of variation, the temperature of heating tubers for 40 seconds and three light spectra were selected: 440-485 nm (blue), 500-565 nm (green), 625-740 nm (red).…”

Improving the calculation of collecting perforated pipelines for water treatment structures

“…Most often, the collection of water and the operation of an entire treatment structure is carried out under a uniform mode. Pipelines and channels with perforated walls are usually used to ensure the uniform (or abiding by a certain law) water discharge from the volume of treatment structures [1][2][3]. In this case, perforation is most often executed in the form of holes or slits [4].…”
