“…В работе [6] рассматривается использование сорбента на основе доломитового сырья для очистки сточных вод, содержащих ионы Cu 2+, Zn 2+ . Результаты исследования сорбционных свойств природного модифицированного материала показывают, что это высокоэффективный сорбент, являющийся относительно дешевым природным минералом, может обеспечить очистку от комплексного загрязнения ионами тяжелых металлов до необходимых параметров при регенерации оборотной воды, но его свойства резко снижаются в кислых средах.…”

The basic structural characteristics of the membrane and kinetic dependences of the electron-filtration separation of wastewater of the brassing process are investigated. The retention factor and the specific output flow for the near-anode and near-cathode membrane were calculated. The dependences of the retention factor and the specific output flow on the transmembrane pressure and current density are analyzed, and it is noted that the anode membrane as a result of the application of a constant electric potential to the membrane-solution system starts to clog and a sludge layer forms on its surface due to the electrochemical process. A comparison is made of the retention capacity of OPMN-P and OPMN-K membranes for a real spent technological solution after the process of brazing and a model solution containing the same concentrations of copper ions (Cu2+) and zinc (Zn2+) as in real runoff. The structural characteristics of nanofiltration membranes of the type OFAM-K and OPMN-P were studied and analyzed. Changes in the crystalline and amorphous phases of the active layer and the membrane substrate are considered. The change in crystalline parameters in crystallites can be explained only by the structural features of macromolecules of polyamide and their orientation during crystallization. Under the action of transmembrane pressure and transport of water molecules, the polymorphism of the packing of the crystal lattice occurs. The packing density of the amorphous phases of the working membrane decreases, which affects the transport and selective properties of the membrane. In fact, the deformation of an amorphous-crystalline polymer leads to a restructuring of the structure not only in the orientation of the macromolecules of the amorphous, but also the crystalline phases of the membranes. It was also noted that the packing density of the amorphous phases of the working membrane decreases, which affects the transport and selective properties of the membrane.

“…The most effective and inexpensive technique for wastewater treatment is the sorption method (Dubrovskay et al 2017;Pohl 2020). Although many number of studies have reported on the treatment of synthetic solutions using sorbents, there is limited literature on the use of these products for the treatment of mine wastewater.…”

This paper presents the results of wastewater treatment at a mining enterprise developing a complex ore deposit in the Murmansk region, Russia. The main pollutants are sulfate, manganese, and strontium. For this complex wastewater treatment, a two-stage scheme was proposed and tested using two sorbents (at a pH of 6): an aminated peat biosorbent to remove sulfate and a commercial sorbent based on the mineral brucite to remove metals. Optimal conditions were established for purifying the wastewater of sulfate and manganese and strontium ions to the level of maximum available concentrations in water bodies for fishery purposes.

The article deals with the problem of rational use of waste of enterprises for the production of silicate cement. Currently the production gliezh waste (burnt clay) does not find its application and is disposed of. A method of obtaining a sorbent based on the gliezh waste is suggested, the aluminium oxide content in which ranges from 15 to 40 % and silicon oxide – from 55-75 %. Pre-burnt clay is treated with sulphuric acid, and then calcined in a muffle furnace at t = 300 °C. The resultant sorbent has high rates of wastewater treatment from heavy metals.
