Výzkum flokulačních a dispergačních činidel při úpravě důlních vod z lomů ČSA a J. Šverma Mostecké uhelné a.s.

Abstract

Thesis is focused to establish basic characteristics of mine wastewaters, pumped from the open-pits “ČSA” and “J. Šverma”. There is collected information on qualitative and quantitative characteristics of the impurities, contained in these waters. Consequently, there are detail descriptions of the operations, having the potential to solve these concentrations in-line with the legislative limits. There is water precipitation hold as key treatment process. The effects of different flocculation and dispersion compounds are studied. Especially the effect of these compounds on agglomeration of dispersed particles and their following sedimentation are studied on real samples of open-pit mine wastewaters from the process-treatment unit ČSA-JŠ“. The possible effects of these treatment compounds on wastewaters reservoirs cleaning are also studied.
