APPLICATION OF ZEOLITE LOADING IN FILTRATION EQUIPMENT FOR TREATMENT OF WASTE AND POLLUTED NATURAL WATER FOR IRRIGATION AND WATERING OF TERRITORIES
Wastewater treatment with the use of natural sorbent as a filter media is considered. The selection of the optimal fractional composition was carried out, at which the effective adsorption properties with respect to chemical impurities were determined. Relevance. At the moment, water is a restrictive but renewable natural resource. The problems of water supply are complicated by the growth of cities, the development of industry, an increase in agriculture and other factors, because wastewater is an inseparable part of society. The most destructive in wastewater is ammonium nitrogen, heavy metals, surface active substances, an excess of the saturation area of which is tantamount to the presence of a poison that is destructive to all living things. For the purpose of the efficiency of wastewater treatment, it is proposed to use sorption filters in which inexpensive natural ameliorants are used as a sorbent. The use of such sorbents will reduce the economic burden and energy costs for the wastewater treatment process on an industrial scale. An object. The object of research is industrial wastewater. Materials and methods. Laboratory and experimental studies were carried out using the example of natural zeolite to select the optimal fraction and its absorption properties relative to chemical impurities in the original waste water. Results and conclusions. According to the results of studies on the selection of the optimal fractional composition and properties of absorption of chemical impurities by zeolite, he showed that when using fractions of zeolite flasks of 0.5 mm, the concentration of impurities decreased by only 10-15%, at 1.5 mm the sorption process stopped, absorption did not occur , and at 1.0 mm, the removal of chemical impurities by more than 100% was observed.
