Multifunctional Coagulants Based on Hidrocarboaluminates Calcium

Sizyakova E. V., Ivanov P. V.

Journal of Ecological Engineering

2017

Vol. 18, nr 2

16--20

The article describes harmful factors from the environmental point of view that accompany almost all stages of the production of non-ferrous metals. Due to the fact that this industry requires large volume of water, these factors require special attention when cleaning wastewater. The contamination of wastewater by non-ferrous metallurgy is characterized by metal ions, particulate pollutants, acids, SAS, etc. A common feature of all these substances is harmfulness, however, they are often very aggressive and toxic. The article focuses on the possible use of hidrocarboaluminates calcium as an active ion exchanger for cleanup wastewater metallurgical production.

Application of Carbonaceous Household Wastes as Fuel Feedstock at Thermo Metallurgical Equipment and Processes

Boikov A. V., Ivanov P. V.

Journal of Ecological Engineering

2016

Vol. 17, nr 3

18--21

The possibility of utilization of municipal solid waste in the conveyor roasting cement production machine along with obtaining secondary thermal energy, what could reach 15-20% of the principal quantity of the heat energy required for the conduct of the process was considered. The inclusion of ash obtained from the incineration of municipal solid waste after preprocessing into the cement clinker composition was proposed. The reduction of the emission of dioxins and furans in the atmosphere and the impact on the environment was achieved as a result.
