The methods and equipment of reduce pollution by sewage are described. Experimental study on treatment of wastewater from oil and on their basis the equipment - thin-layer tank, filter-adsorber that allow you to increase the degree of effluent to 75-85%, which will reduce emissions into the environment.

The main indicators of water use in cities of Belarus are considered in the article. They are: sufficiency of water resources, total water intake per capita, proportion of groundwater in total water intake per capita, domestic water consumption per capita.

The mutagenic treatment improves the properties of the activated sludge. It allows to create new versions of bacterial populations that are more resistant to adverse factors. The use of chemical mutagenesis techniques increases the dehydrogenase, catalase and peroxidase activity of microorganisms of ...

Performed the analysis of retrospective and recent state of the general efficiency of functioning the Danube rice irrigation systems basis on the complex of substantiated criteria of technological, economic and ecological efficiency and determined their rational values for the studied conditions

The article describes the General characteristics of the information of water use in the river Dnepr basin , which is necessary for detecting problems of water use and protection when drawing up the schemes of complex use of water resources.

This paper describes the data control water-air regime of soil and providing payment bits and pieces of technology and subsoil moisture regime on drained lands.

The main agrochemical properties of defecate and conveyor washing sludge as a waste of sugar manufacture, promising for use in agriculture are investigated. It is shown that the main obstacle to widespread application of the conveyor washing sludge is its pollution by heavy metals of the first hazard ...

The article considers the flocculation parameters experimental investigations. These investigations are intended to improve the treatment technology of the metalcontaining wastewater of the galvanic (electroplating) production. The obtained results permitted to develop a number of practical recommendations ...

We studied the phytoplankton of the river Mukhovets in 2013. Found 41 species of algae of 7 departments. 78 % of all species of algae are of 3 departments: Bacillariophyta, Chlorophyta and Cyanophyta. The low species diversity of phytoplankton river Mukhovets may indicate a high level of water pollution.

Analysis of composition of sludge industrial wastewater was done in order to develop methods of their application as a soil-additives.
