Technology of preparation of natural waters for irrigation

Research and search for the most effective and cost-efficient ways of water treatments is relevant today. We propose the use of a natural sorbent as a filter load of a sorption filter for the preparation of natural water for irrigation of crops. The object of study is the water of the Volga River in the Volgograd region. In this work, we propose the use of a sorption filter for purification of natural water, where natural zeolite will be used as a filter load. Before the experiment, a chemical analysis was performed to determine the contaminants in the water and their concentrations. The fractions of zeolite were selected using fractional sieves. Based on the results of sedimentation, the optimal fraction of natural zeolite in terms of absorption properties and contact time with the studied water was selected. Based on the results, the statistical processing of the experimental data was performed and the dependences presented in the form as a power model were obtained. Thus, on the basis of the conducted studies, it can be concluded that it is advisable to use a sorption filter with a zeolite filter load for the preparation of natural waters to be used in irrigation.
