| Title of the article | Purification of natural waters from borate ions using ion exchange |
| Abstract. | Problem statement. Purification of natural waters from boron compounds is of scientific relevance, since it allows solving the problem of providing the population with high-quality drinking water. One of the ways to purify natural waters from boron is the ion exchange method. The aim of the work is to conduct research on the removal of boron from water using pressure ion-exchange filters. The objectives of the work are: to study the processes of purification of boron-containing waters in pressure ion-exchange filters with various ion-exchange resins; to determine the effect of filtration rate on the cleaning efficiency; to determine the effect of pressure in pressure filters on the cleaning efficiency. Results. The main results of the research are that the efficiency of water purification from borate ions on various ion exchangers is determined, the influence of filtration rate and pressure in pressure filters for the purification of boron-containing waters is determined. Taking into account the results of the research, a plant for the preparation of water containing high concentrations of boron for household and drinking needs has been developed. Conclusions. The significance of the obtained results for the construction industry consists in improving the quality of the preparation of boron-containing groundwater. The most effective ion-exchange loading and technological parameters of purification of boron-containing waters in pressure ion-exchange filters have been determined. The best result (cleaning effect 71-87%) was shown by Granion D403 brand ion exchanger. Studies have shown that an increase in the filtration rate in ion-exchange filters reduces the efficiency of their work, and an increase in pressure at the inlet to the ion-exchange filter does not affect this value. An installation for the preparation of groundwater with a boron content of up to 2.3 mg/l with a capacity of 200 m3/day has been developed. |
