Item Reclaiming of Water Resources in Condition of “Green Economy”(Сумський державний університет, 2018) Маценко, Олександр Михайлович; Маценко, Александр Михайлович; Matsenko, Oleksandr Mykhailovych; Торба, Іван Валерійович; Торба, Иван Валерьевич; Torba, Ivan ValeriiovychOften, water after use is all too often seen as a burden to be disposed of or a nuisance to be ignored, although wastewater is one of the main components of the rational water use cycle. The result of this attitude is the degradation of aquatic ecosystems, the increase in the number of diseases transmitted through water from contaminated freshwater sourcesItem Chromium (VI) ions extraction from water(Sumy State University, 2017) Tolstopalova, N.M.; Obushenko, T.I.; Kostoglod, O.B.The aim of this work was to research hexavalent chromium solvent sublation. This method was founded on combination of flotation and extraction methods which is based on transmission of gas bubbles through the aqueous phase and passing pollutant substances (sublate) into organic phase. Organic phase must be lighter then water and must not dissolve in it. Solvent sublation has such advantages as possibility of multiple pollutant ions concentration in small volumes of organic solvent; possibility of valuable components regeneration; much smaller amount of organic solvent is used (compered to extraction method); process is not limited by the distribution constant; absence of foam (compared to flotation); less wet sludge [1].Item The sewage sludge detoxification(Сумський державний університет, 2013) Черниш, Єлізавета Юріївна; Черныш, Елизавета Юрьевна; Chernysh, Yelyzaveta YuriivnaRecycling of organic sewage sludge today is an urgent problem in the whole territory of Ukraine, which requires a solution. At the most of the municipal wastewater treatment plants, unfortunately, current removal, treatment and recycling of sewage sludge are not properly resolved. At present, the general part of sewage sludge is not carried out. Because it contains toxic chemicals, mainly heavy metals (HM) within the industrial waste water coming into the city sewer system after insufficient treatment or without treatment. As a result, sewage sludge is sent to the sludge pit and storage sites, which are assigned to the large land area. Therefore the process of HM removing from sewage sludge is of paramount importance to allow using sewage sludge as an organic fertilizer in agriculture.
