The literature data on the crushed walnut shells usageas a sorption material for metal ions, dyes and some organic compounds removal from aqueous media are summarized. Trees of the Juglans regia species are widespread in Russia; their shells are natural annually replenished material that is of industrial importance and can be used as sorption material for the extraction of many pollutants from aquatic environments. The paper gives a characteristic of the walnut shell, shows the indicators of the main substances that make up the shell (cellulose, lignin, hemicellululose), indicates the approximate specific surface area for BET and the content of functional groups. The results of studies of the adsorption of metal ions and and some dyes adsorption by walnut shellsare considered. The values of sorption indices for the studied pollutants are given. It is shown that it is possible to increase the sorption characteristics by chemical modification of the Juglans regia shell. It is determined that sorption isotherms in most cases are more fully described by the Langmuir model, and the process kinetics in all cases obeys the pseudo-second order model.

The paper describes the issues associated with waste generated during steel production and processing, in particular the dust from electric arc furnaces (EAF). An effective solution for the disposal of such waste is its involvement in processing to obtain valuable products. This paper studies the physical and chemical properties of EAF dust produced during the smelting of metallized pellets and captured by the dust and gas cleaning system of the steel-smelting shop at the Oskol Electrometallurgical Combine, Belgorod Region. The results obtained in the study of the chemical and disperse compositions of dust, the microstructure of the surface made it possible to propose the use of dust as a raw material for coagulant production. The conditions of acid-thermal treatment of dust are determined, contributing to the partial dissolution of iron (II), (III), and aluminium compounds, which ensure the coagulation processes during wastewater treatment. Model solutions show high efficiency (> 95 %) of water treatment from heavy metal ions by modified EAF dust.

The possibility of producing iron and silicon-coagulant-flocculant for purification of waste water was shown. The electric steel melting slag JSC "OMK-Steel" has been used as the starting material, in which the content of iron oxide to 25.8% and silicon dioxide is 17.6%. The optimal parameters of slag hydrochloric opening were as follows: the modification time at T = 40 °C – 1 hour, the concentration of hydrochloric acid – 1.5 N, the ratio of the solid and liquid phases of S : L = 1 : 10. In these settings the concentration of hydrosilicic acid (for silicon) will be 1532 mg/l; the concentration of iron – 1250 mg/l has a lower concentration of silicic acid in the production of the solution with increasing temperature and time of exposure. This paper examined the chemical aspects of the process of obtaining the new iron-containing coagulant-flocculant based on electric furnace slag. The results can be used to produce coagulants and flocculants using industrial waste.
