The article presents a modern technological solution in the field of preparation of hydrogen sulfide natural waters for domestic and drinking and technical purposes. The developed technology of iron-catalytic purification of natural hydrogen sulfide-containing waters in a reactor with an ultrafiltration separator is easy to operate, a small amount of peripheral equipment and a high speed of processes, and also has no by-products and is completely environmentally safe. The proposed technological parameters are experimentally obtained and confirmed using approved scientifically based methods of analysis, the use of metrologically certified instruments and equipment, a large amount of experimental data and their high convergence with calculated values. The presented solution can be recommended for use at water treatment facilities for the purposes of water supply to enterprises, small blue areas and individual households.
