Purification Of Water

The article is devoted to measures for the purification of water and air medium from polychlorinated biphenyl wastes by the method of UV radiation and NiO2 nanoparticles, on PCBs (polychlorinated biphenyl) constituting groundwater in PCB waste disposal areas, the possibility of neutralizing PCBs in the atmosphere in industrialized areas. A method for the degradation of polychlorinated biphenyl contained in waste and industrial waters, as well as in atmospheric air, has been proposed. Air purification is carried out with ultraviolet and microwave radiation, and ultraviolet radiation and TiO2 nanoparticles are used for water purification. Based on the analysis performed,the problem of optimizing the purification of groundwater and atmospheric air contaminated with polychlorinated biphenyls has been formulated and solved. An expression is proposed for the dependence of the cleaning time on the distance to the place of initial environmental pollution.

Purification Of Water

Membrane distillation (MD) is a rapidly developing field of research and finds applications in desalination of water, purification from nonvolatile substances, and concentration of various solutions. This review presents data from recent studies on the MD process, MD configuration, the type of membranes and membrane hydrophobization. Particular importance has been placed on the methods of hydrophobization and the use of track-etched membranes (TeMs) in the MD process. Hydrophobic TeMs based on poly(ethylene terephthalate) (PET), poly(vinylidene fluoride) (PVDF) and polycarbonate (PC) have been applied in the purification of water from salts and pesticides, as well as in the concentration of low-level liquid radioactive waste (LLLRW). Such membranes are characterized by a narrow pore size distribution, precise values of the number of pores per unit area and narrow thickness. These properties of membranes allow them to be used for more accurate water purification and as model membranes used to test theoretical models (for instance LEP prediction).

The Impact

After the airport is put into operation, a large amount of wastes generated every day will bring waste disposal pressure and ecological environment pressure to the airport and surrounding areas. This article expounds the current methods of airport waste disposal. According to the principle of waste reduction, harmless and reclamation, a set of solid waste gasification methods suitable for airports are proposed, which can reduce waste transportation and landfill costs, effectively control the impact of environmental pollution. At the same time, it can use waste heat to generate electricity to turn wastes into treasure and promote green airport construction.

Operational Characteristics

One of the effective ways to solve the environmental problems of the region at present is the waste disposal from Novocherkasskaya TPP, one of the largest sources of environmental pollution. The solution to this problem is associated with the integrated use of ash and slag mixtures components in the effective building materials’ production. On the TPP waste basis, the authors obtained structural and heat-insulating concrete with enhanced physical, mechanical and operational characteristics.

Society's growing concern over environmental pollution has forced American industry to reevaluate its methods of waste disposal. No longer is it socially acceptable or, in many cases, legal to dump untreated by-products into the air, on the land, or into the rivers. Industries have developed various methods for complying with pollution legislation and social demands. Paramount among the programs now in effect are detoxification facilities and waste recycling programs.
