Abstract
The article is devoted to the creation of a multi-section water purification filter, which can be made by hand at home. At the same time it is necessary to apply in the filter the automated control of pollution of membranes in sections of the filter. The main purpose of the study is to develop a simple and cheap multi-section filter for drinking water purification. The filter must have different cleaning technologies with the possibility of its own manufacture and with the possibility of automated control of membrane contamination. The task of the research is to develop and manufacture a working model of a multi-section filter for drinking water purification. The design of the filter should be multi-section with membranes containing various fillers for water purification; simple and cheap to make at home. The design of the filter should provide for automated control of the degree of contamination of the membranes in the filter sections. By analyzing the existing common household water filters, the most optimal solution for developing your own design of a household water filter has been determined. As a result of the analysis, a working model of a three-section water filter was created. The first section of the filter contains a membrane with quartz sand, the second section contains a membrane with activated carbon powder, the third section contains a membrane with small pieces of shungite (or with small pieces of silicon). As a result of an experimental study of the filtration of contaminated water using a three-section filter was determined next. The weight of water after passing through the filter decreases due to the retention of substances with a density greater than that of water (solid impurities). Also, the filtered water became clear and stopped foaming when shaken. This confirms the efficiency of the proposed filter. The developed three-section filter can be used as a separate stand-alone water filter or in addition with household polypropylene water filters for quality filtration of impurities up to 1 micrometer.
