Based on the proposed new energy- and resource-saving methods, a fundamentally new technological scheme of wastewater and sludge processing with the reuse of purified water has been developed. The synthesis of nanosorbents was carried out on a technological installation made by the authors of the project for the production of dispersed materials with a specific surface area of more than 300 m2/g. The developed technology also provides disposal of waste in products that contain magnetic radio-absorbing materials. In addition, the synthesis of effective nanosorbents by ferritization methods was carried out and the regularities of their use for water purification at industrial enterprises were studied. The method of ferritization purification of wastewater from heavy metal ions using energy-efficient electromagnetic pulse discharges to activate the process with the amplitude of magnetic induction in the range of 0.1 - 0.3 T has been improved. Purified water complies with the norms of the State Sanpin N 452/17747 "Hygienic requirements for drinking water". Experimental samples of commercial products were created - powder paint coatings using water treatment waste, which have chemically and thermodynamically stable ferromagnetic structures for shielding electromagnetic radiation. The resulting coatings comply with DSTU ISO 9227:2015, DSTU ISO 12944-1:2019 and DSTU ISO 12944-2:2019. Rational technological and constructive parameters of the operation of the equipment in the above-mentioned processes have been developed for the effective use of raw materials and energy resources, reagents. This will contribute to the introduction of environmentally friendly production technology with the production of dual purpose materials.
