Estimation of the effectiveness of Sokirnit zeolite in removing ammonium ions at the quarry wastewater treatment facilities of Vostochno-Beiskii razrez, LLC

Summary

The article presents the results of tests on tertial treatment of real quarry wastewater with different ammonium ion concentration by filtration using Sokirnit type 1 natural zeolite. The tests were carried out with three samples of real wastewater in a laboratory setup that provided for the precise reproducibility of all conditions during the experiments. It was found that the dynamic exchange capacity related to ammonium ions was affected by their concentration in the crude wastewater with a design contact time with zeolite of 10 minutes. Preliminary proposals for adjusting the design process flow scheme and modes for quarry wastewater treatment at the treatment facilities of Vostochno-Beiskii Razrez LLC were developed.

Problems of wastewater land disposal and possible solutions
(for discussion)

Summary

The problems and risks associated with the land disposal of effluents, as well as possible solutions to these problems, are considered. A comprehensive analysis of the environmental risks associated with this method of wastewater disposal, which has long been widespread, however, up to now is not regulated by law so far, is presented. The main problem is that contaminated wastewater, getting into the soil, can infiltrate into underground aquifers resulting in long-term environmental disasters. It is emphasized that this method can only be used in exceptional cases, when other options are impossible, and only in strict compliance with a number of conditions and technical requirements. The most important of these are treatment technologies, such as lagoons, with more stringent technological standards and constant monitoring of wastewater quality. It is concluded that, if all the necessary measures and restrictions are observed, the land disposal of effluents may be justified in specific situations; however, provided thorough preparation and control in order to minimize possible negative consequences for the environment.
