“…Technological scheme is shown in the Figure 4, overview of the facility on the Figure 5. The facility showed stable work after the upgrade with necessary amount of biofilm on the floating media ( Figure 6) and high efficiency of BOD, nitrogen and phosphorus removal [9,10]. Figure 7 shows how the nitrogen concentration changed in the reactors.…”

Abstract. The article touches upon the efficiency of small capacity wastewater treatment plant for industrial sewage. Current operation scheme fails to meet existing regulation requirements due to several drawbacks. The article describes a technology for wastewater treatment and the construction of bioreactor to implement the scheme above. The technology includes averaging tank with preliminary mechanical treatment and bioreactor with floating feed. This provides the efficiency of removal of organic compounds and nutrients: BOD -96%, nitrogen -99%, phosphorus -89%.

Abstract. The purpose of the study is to develop theoretical provisions and practical tools for attracting investment resources for the renewal of the fixed assets of the housing and communal services enterprises (hereinafter Housing and Communal Services). In the article the condition and reveals, the trends in the development of the housing and communal services have been analyzed, the forms and methods of the attracting investment resources have been explored, a model for identifying the most priority projects for the reconstruction and renovation of the communal infrastructure have been formed, a mechanism for searching for and attracting extra-budgetary sources of the investment has been developed, and an algorithm for monitoring the effectiveness of the using extrabudgetary sources of the investment has been formed. The research was carried out using a system approach, economic and mathematical modeling, general scientific methods, methods and statistical analysis. The processing of the information obtained through analysis and modeling was carried out using modern methods that support collection procedures.

The article reveals various factors, which determine the maintenance of membrane bioreactors for treatment of domestic and industrial sewage. Contamination of membranes is a consequence of poor pretreatment, when membrane accumulates hair, scraps of rags and other fibrous materials on its' fibers and in the cavities of membrane blocks. Aeration conditions have a significant impact on the performance of the membranes, also in sufficient sludge liquor mixing leads to membrane clogging. Size of pores, material of membrane and washing peculiarities are the factors that can affect MBR operation. The costs for installation and operation of membrane modules is still the limiting factor of their wide application, however now the situation is changing. There are key differences between membrane and conventional treatment of wastewater revealed such as costs, required area and quality of treatment.
