The author argues that the current standards of the quality of discharged waste waters are the drivers of new technologies of their treatment. Now traditional biological treatment is considered a universal method. However, compliance with the most recent standards requires that efficient removal of phosphorus in the course of biological processes must rise from 20 - 40 % to 98 - 99 %, efficiency of treatment of ammonium must go up to 98 - 99 %, while the share of nitrate and nitrite compounds formed in the course of biological treatment must be limited.
Given the fact that the contemporary method of treatment of waste water must meet the ecological requirements and be economical, improved technologies of biological treatment are most acceptable ones.
For practical purposes, the most solicited technologies are those that are based on the alternation of aerobic and anaerobic conditions of treatment of waste waters and/or active sludge. The most widely spread aerobic - anaerobic technology of treatment employs the method of biological nitrification - de-nitrification, which is the only method of removing all nitrogen compounds (ammonium, nitrite, nitrate) in accordance with the regulations that are effective in our country.
Any accompanying microflora boosts the overall biomass, and the laminar structure of the biological film assures the simultaneity of both aerobic and anaerobic processes, and, therefore, it intensifies the process of treatment.
Application of chemical treatment is an essential constituent of the waste water treatment technology, as it assures in-depth removal of phosphorus.

In the article the working principles of wastewater biological treatment for food companies is reviewed, including dairies and breweries, the waters of which are highly concentrated with dissolved organic contaminants and suspended solids. An example of successful implementation is anaerobic-aerobic treatment plants. Implementation of these treatment plants can achieve the required wastewater treatment at the lowest operational expenses and low volumes of secondary waste generated. Waste water from the food companies have high concentration of various organic contaminants (fats, proteins, starch, sugar, etc.). For such wastewater, high rates of suspended solids, grease and other contaminants are characteristic. Wastewater food industry requires effective purification flowsheets using biological treatment facilities. At the moment methods for the anaerobic-aerobic purification are applied. One of such methods is the treatment of wastewater at ASB-reactor (methane reactor) and the further tertiary treatment on the OSB-reactor (aeration). Anaerobic process means water treatment processes in anoxic conditions. The anaerobic treatment of organic contamination is based on the process of methane fermentation - the process of converting substances to biogas. The role of biological effluent treatment is discussed with special attention given to combined anaerobic/aerobic treatment. Combining anaerobic pre-treatment with aerobic post-treatment integrates the advantages of both processes, amongst which there are reduced energy consumption (net energy production), reduced biological sludge production and limited space requirements. This combination allows for significant savings for operational costs as compared to complete aerobic treatment without compromising the required discharge standards. Anaerobic treatment is a proven and energy efficient method to treat industrial wastewater effluents. These days, more and more emphasis is laid on low energy use, a small reactor surface area, low chemical usage and reduced sludge handling costs. When stringent discharge limits have to be met, in many cases anaerobic treatment is followed by aerobic post treatment. During aerobic polishing, final traces of organic pollution (COD/BOD) and nutrients such as nitrogen and phosphorous can effectively be removed. Besides the decrease in the biosolids quantity, the quality of the aerobic sludge is often improved. With anaerobic pre-treatment biodegradable carbohydrates are less easily present in the aerobic reactor inlet. As a result, the number of filamentous bacteria causing bulking sludge in activated sludge plants, is significantly reduced. This results in an improved settleability of the aerobic sludge and consequently a more stable and secure operation of the activated sludge plant. Finally, due to the higher mineralization grade dewaterability of aerobic sludge from activated sludge plants after anaerobic pre-treatment it is often better than without anaerobic pre-treatment.

The author presents the results of microbiological studies aimed at investigating the deep removal of phosphates from household wastewater. A method for deep cleaning of waste water using reinforced materials is provided. The living culture study in activated sludge and biofilm in the light microscope showed activating effect of the reinforced loading material on the life of microflora in activated sludge and biofilm. A steel wire in the the feed material has a significant impact on the number and variety of species of protozoa in the activated sludge, and also leads to rapid development of Chlorella sp. The study of the living culture of activated sludge and biofilm in the light microscope showed that the reinforced material activates the vital functions of the activated sludge microflora and biofilms, as well as the diversity of their species composition. The studies have confirmed that chlorella multiplies in an environment rich with iron, absorbs phosphorus from the environment and actively produces oxygen, providing bacterial biomass with it. This fact explains the increase in the removal of organic contaminants, as well as the influence of the reinforced material on the second step of nitrification.

In this paper, the authors analyze the quality of the groundwater in the north-western region of Ukraine and propose the reassessment of a number of retrofit technologies for their comprehensive treatment. The authors argue that the underground water is a multi-component system. The authors propose a set of biological, physical and chemical methods of water treatment for a synergistic effect.The authors suggest reducing the number of consecutive water treatment units and using an advanced technology (activation of biological and physicochemical processes in a constant magnetic field). Another suggestion is the application of a set of technologies integrated into traditional methods of biological treatment. The authors also propose a consistent process of water treatment, so that the sub-processes within it were able to activate each other at each subsequent stage to achieve a synergistic effect. Degradation of organic iron requires a biologically active environment. The underlying technology can be transformed into more sophisticated process patterns depending on the quality of water exposed to treatment.

The findings of the research project that encompasses 137 small municipal wastewater treatment plants (WWTP) are presented in the paper. The source data for the research is the official statistical reporting according to Form № 2-TP (water) submitted in 2010, as well as the information on completed and approved projects that demonstrate admissible discharge standards.
The method of environmental assessment of barrier capabilities of municipal WWTP based on six major indicators (TSS, BOD, N-NH4+, N-NO2-, N-NO3-, P-PO43-) is proposed to ensure compliance with the present-day environmental standards.
The maximal likelihood of incompliance with the pre-set standards is demonstrated by phosphorus phosphate (97 %), ammonium nitrogen (95 %) and nitrite nitrogen (79 %). The substances that demonstrate their maximal excessive content in the wastewater include phosphorus phosphate (its content exceeds the admissible standard 18-fold), ammonium nitrogen (21.7-fold excess) and nitrite nitrogen (7.6-fold excess).This overview indicates a low possibility of compliance of the content of N-NH4+, N-NO2-, and P-PO43- with the environmental standards that extend to biological WWTPs.
The highest relative excess of the admissible content of admixtures is typical for the plants that have a design capacity of 600-800 m3/day and that process 50-200 m3/day. The lowest relative excess of the admissible content of admixtures is typical for the plants that have a design capacity of over 1,000 m3/day and that process over 500 m3/day. The average relative excess of the admissible content of admixtures for all plants equals to 8.4 times.
The ecological assessment of the barrier capabilities of small municipal WWTPs has proven that their compliance with the standards of admissible content of N-NH4+, N-NO2-, and P-PO43- in the wastewater is impossible to attain in practice.

This paper addresses the biological treatment of wastewater associated with removal of nitrogen.
Results of laboratory experiments that involve nitrification and denitrification are also presented
and analyzed in the paper.
Discharges of inadequately treated and untreated wastewater have a negative impact on
the aquatic ecosystem. The biological treatment of the wastewater that includes denitrification is
strongly influenced by external factors. They need thorough research at the stage of design of water
treatment facilities.
The objective of this research is development of effective construction technologies on the
basis of experimental studies with a view to the modernization of biological wastewater treatment facilities.
The analysis of the latest scientific papers on water treatment demonstrates that the singlesludge
nitrification and denitrification technology is the most effective and the simplest one in terms
of its implementation.
The studies were conducted at the research laboratory of Moscow State University of Civil
Engineering. The laboratory facilities make it possible to perform the processes of nitrification, denitrifiation and sedimentation. The composition of the wastewater used in the experiment was close
to that of the natural wastewater.
Optimal process parameters of a wastewater treatment plant, including capacities of nitrification
and denitrification tanks and concentrations of nitrate required for effective biological removal
of phosphorus, were identified in the laboratory. Positive results were obtained in terms of removal
of organic compounds and nutrients. The technology of nitrogen removal from the wastewater was
developed. The proposed technology of modernization of biological wastewater treatment facilities
is based on conversion of existing aeration capacities into nitrification and denitrification zones, and
it does not include construction of any new premises.
