There was presented improved design of Venturi scrubber with adjustable throat, intended for trapping particles from gas phase with more than 0.5 microns. There were determined hydrodynamic modes of operation of a new Venturi scrubber corresponding to the greatest efficiency in trapping particles. There was described flow chart on aspiration of emissions of mineral fertilizers production. There was made a comparison between the results of a mathematical model and test data on trapping of KCl particles during aspiration of shop for production of potash fertilizers. The residual dust content achieved is less than 10 mg/m³. There were presented equations for calculation of offered Venturi scrubber.

The work is devoted to studies on the treatment of brackish groundwater with an elevated iron content using polymeric nanofitration and precipitated ultrafiltration membranes. There was studied efficiency of treatment from iron compounds by means of precipitated membranes based on bentonite. of Milosky deposit in native form and bentonites with the addition of polyakrylamide and diallyl dimethyl ammonium chloride. There were investing permeability of the methods of the deposited membranes and the methods of their regeneration. There was proposed a basic process scheme for treatment of brackish groundwater with increased brackish groundwater content of iron.

The reasons of formation of oily waste on ship board, their main types and reasons of dumping into the sea, as well as the problems of their identification on satellite images are considered. The type and volume of oily waste generated and stored on board a vessel, as well as those carried in bulk, depends on various factors. These include the type, age and size of the vessel, as well as the type and age of the engine system and equipment that is designed for the separation, storage and disposal of residual oil products and other ship wastes. Often, these wastes containing oil, oil products and other oily substances are dumping into the sea as a result of both illegal and quite standard legal operations. In these cases, they are called ship-made oil spills, clearly visible on images from space, and their space-time characteristics can be studied using satellite monitoring.

The results of the presented complex of studies made it possible to determine the main sorption properties of zeolite-containing raw materials of Transbaikal, which in its turn, determined the setting of the experiment to dtudy the regularities of sorption extraction of petroleum products and heavy metals ions from industrial sewage of railway transport enterprises. There were considered different options of natural zeolite’ modifications of Kholinsky deposit for the creation of sorbents possessing high sorption activity in relation to petroleum products and heavy metals ions. As modifiers are selected high-organo-silicon compounds – hexamethyl disilazane [(CH₃)₃Si]₂NH and tetraethoxysilane (С₂H₅O)₄Si, promoting hydrofobization of surface. Aside from that, as modifier be used sulfur polymer obtained from waste of ethylchlorhydrine production. This will solve simultaneously two problems: recycling of waste and wastewater treatment, which is beneficial from economic point of view.

In the Russian Federation there are two types of launch vehicles more frequently used – “Soyuz” (medium capacity class) and “Proton” (heavy-duty class). Impact of launch vehicles on the environment appears both on terrestrial ecosystems (in the areas of the fall of the separating parts of launch vehicles), and different layers of the atmosphere on the route of heir launching. The greatest impact is observed in the areas of the fall of areas of the fall of the first stage launcher, which is manifested in varying degree of mechanical damage, pyrogenic and thermal transformation, chemical contamination of ecosystems. Comparative analysis of influence of launch vehicles’ launching in the areas of the fall of the second stage launcher did not is reveal specific features of impact of different types of launch vehicles The basic environmental issue in these areas is contaminations of contamination by fragment of fallen stages.

There was considered chemistry and offered environmentally sound safe way of chemical cleaning and removal of insoluble thermally and chemically resistant deposits, which are formed in steam boilers (on the sample of boilers of small and medium pressure). On the base of X-ray and radiographic analysis of these deposits was established their phase and elemental composition, substantiated conditions of its dissolution and decomposition. There were conducted experimental research of dissolution dynamic of insoluble components of deposits – wollastonite, diopside, tremolite, calcium hydroxyapatite and carbonate calcium and magnesium by prepared water after sodium cycle with addition complexon (Trilon B) and reagent HydroGhem 160.

There were presented results of investigations of zooplankton’s structural organization and chemical composition waters of water cooler of Beloyarskaya NPP. Investigations conducted during period 2012–2014. There was studied species composition, distribution in spaсe, seasonal dynamics of population and biomass of zooplankton. There were investigated alterations zooplankton’s structure during passing through the NPP’s cooling system. There was made assessment of Beloyarsk reservoir’s water quality by indicators of zooplankton.

The article delivers the analysis of current problems and reasons connected with atmospheric pollution in cities by hazardous emissions of vehicles. There was conducted a comparative analysis of Russian and foreign researches on hazardous substances emissions that are results of tyres, breaking mechanisms and road surfaces wear. The article proves a conclusion on increasing air pollution in big cities by particulates and especially by suspended particulates due to a growing number of vehicles.

There were presented operational and functional properties of water-mix cutting fluids (CF). There was detected inconsistency of requirements between process engineers and standards developers to quality of water used for the preparation of CF, with operating conditions. There was substantiated possibility and advisability of reduction of requirements to water quality as the base of CF.

There was presented model of ecological situation’s assessment in the city of Krasnoyarsk> that was developed using methods of nonparametric modeling, on the base of observation data of State Monitoring Network for 2012. There was substantiated flexibity and simpliciiy of modeling of various implementation of environmental situation. The proposed approach will optimize the procedure of decision making in the field of environment quality management when tasks are solved for selection expand the model, which will predict the spread of pollution not only in space but also in time and will increase you the accuracy of forecasts. Simulation speed allows you to use this method in real time.

The capabilities and expediency of the account of aesthetic components in the engineering protection of the environment were considered. Examples on aesthetic decisions in the development of environmental solutions were discussed. It is shown that the aesthetic approach to the creation of ecological and protective equipment allows not only solving technical problems for the protection of the natural environment, but also creates the conditions for comfortable life of people. For the decision of problems on education of ecological consciousness necessary to attract professional artists, architects, designers to create environmental-protective facilities and equipment. There is no doubt that environmental aesthetics has an important role in ecological education of people. It should be a component of environmental education, which will help to move away from currently accepted stamps in the training of professional ecologists.
