Water scarcity has become one of the chronic environmental issues that threaten human lives in various areas in the world. Various frameworks and approaches have been developed to determine the water scarcity, and most of the results propose to reduce the scarcity by lowering water consumption and increase reuse. However, in addition to the water scarcity caused by over-exploitation of water...
The technogenic transformation of the water ecosystems under the dredging is one of the actual problems for the near-shore waters. The main primary producer and the base of food webs in the seas are microscopic algae which are suspended in waterbodies. The phytoplankton of Luga Bay (the second bay of the Gulf of Finland) was investigated during the period of Ust-Luga commercial seaport...
Potassium butyl xanthate (PBX) is widely used as a reagent in ore dressing by flotation. For this reason, it is present in the wastewater of these industries [Goryachev, 2014; Ignatkina, 2014]. Oil products are found even more often in a wide variety of waste waters. They, like flotation reagents, have a depressing effect on aquatic organisms. At present, biotesting methods are widely used to...
Many materials with varied characteristics have been investigated for water purification and separation applications. Traditional membrane technology is a separation process that allows species to pass through the membrane depending on the pore size. This study offers a new design principle: controlling cations' transport with graphene oxide-polyethyleneimine (GO-PEI) membrane. The regulation...
The efficiency of purification of low-turbid waters directly depends on the intensification of the process of sedimentation of particles in the liquid. At present, in order to accelerate the precipitation process during settling, various weighting additives are used, for example, quartz sand with a particle size of 0,05 - 0,14 mm, iron powder, magnetite with a particle size of no more than...
Объектом исследования является экосистема крупнейшего в Западной Сибири Новосибирского водохранилища. Цель работы – изучение механизмов формирования качества воды, протекающего в различных частях водохранилища по-разному. Новизна: моделирование экологических процессов в его различных акваториях и в водохранилище, в целом, на основе воспроизведения биогеохимических циклов лимитирующих...
The present work is devoted to the study of the process of iron oxidation in groundwater. The main impurity of most groundwater is iron compounds due to geological features. Therefore, the main stage in water treatment technologies is the stage of iron removal which includes several stages: oxidation, precipitation and filtration. The limiting stage is the oxidation or precipitation stage of...
The relevance of the research topic is determined by the increasing role of natural reservoirs and their vegetation in the processes of self-purification of ecosystems against the background of increasing pollution of natural environments. Due to the constant anthropogenic impact especially near landfills, many toxicants including heavy metals enter the environment. They cannot be removed...
For a long time, water sources determined the places of settlement of people, since it is prerequisite for the live. Currently, the development of the human society has led to a scarcity of fresh water resources around the world. By 2025, about 1.8 billion people will suffer from extreme water shortages (<500 m3 per year per capita), and two-thirds of the population will meet “high stress”...
The relevance of the work is determined by the increasing pollution of aquatic environments by toxic substances (including surfactants, hydrocarbons and their mixtures). As a result, it becomes necessary to develop methods for biotesting the quality of natural and waste waters that contain the above-mentioned substances, as well as to clarify the mechanisms of the toxic effect of pollutants....
Химический состав вод является результатом сложных многоступенчатых процессов, происходящих как на водосборе, так и в самом водоеме. Основными природными источниками поступления элементов в водную среду являются выветривание горных пород на водосборе, высвобождение из донных отложений, выпадение из атмосферы, минерализация органического вещества на водосборе и в самом водоеме. Антропогенная...
Arid and semi-arid areas globally face the greatest pressures to deliver and manage freshwater resources. These areas are particularly vulnerable to climate variability or climate change, with consequences that may have very serious social and environmental effects. Accurately assessing and managing available and renewable water resources is more diffi-cult in semi-arid regions, compared with...
Studies have shown that the use of chelating compounds in directed phytoextraction significantly increases the uptake of heavy metals by plants [1]. In the course of this study, laboratory experiments were carried out to obtain results on the possibility of using Eichhornia crássipes with the chelating phosphorus-containing agent of disameted potassium salt of oskietilidene diphosphonic acid...
Проблема обеспечения качественными водными ресурсами для Республики Крым чрезвычайно актуальна в настоящее время, ведь по запасам собственных водных ресурсов полуостров Крым является наименее обеспеченным собственными водными ресурсами регионом Российской Федерации.
В существующих условиях использование водных ресурсов характеризуется несоответствием режима водопотребления и режима...
