Ecological Aspects

The paper presents up-to-date and perspective requirements for the quality of diesel fuels. The effect of chemical, as well as fractional composition on the quality of diesel fuels is marked. The capability of obtaining prospective ecologically friendly diesel fuel based on the mixture of Azerbaijani oils via hydro-treatment in the presence of the catalyst of alumonickelmolibdene is noted. Ecologically friendly diesel fuels with ASTMD 4294 by sulfur - 0.039 % mass, ASTMD 3227 by sour sulfur - 0.006 % mass, ASTMD 5708 by metals: V ˃ 2 mg/kg, Ni ˃ 1 mg/kg, Fe ˃ 3 mg/kg, Na ˃ 8 mg/kg, as well as with the freezing temperature of ASTMD 97 – 50 оС have been obtained. Such kinds of diesel fuel meet EN standards and provide environmental safety in storage and transportation to the European countries. The prospect of obtaining and using buffer plug (mixture of petroleum products) during consistent pumping of various sorts of oil products without ecologic-economic risks of jet fuels is shown as well.

The tremendous increase in the production and consumption of titanium dioxide (TiO2) nanoparticles (NPs) in numerous industrial products and applications has augmented the need to understand their role in wastewater treatment technologies. Likewise, the deleterious effects of wastewater on the environment and natural resources have compelled researchers to find out most suitable, economical and environment friendly approaches for its treatment. In this context, the use of TiO2 NPs as the representative of photocatalytic technology for industrial wastewater treatment is coming to the horizon. For centuries, the use of industrial wastewater to feed agriculture land has been a common practice across the globe and the sewage sludge generated from wastewater treatment plants is also used as fertilizer in agricultural soils. Therefore, it is necessary to be aware of possible exposure pathways of these NPs, especially in the perspective of wastewater treatment and their impacts on the agro-environment. This review highlights the potential exposure route of TiO2 NPs from industrial applications to wastewater treatment and its impacts on the agro-environment. Key elements of the review present the recent developments of TiO2 NPs in two main sectors including wastewater treatment and the agro-environment along with their potential exposure pathways. Furthermore, the direct exposure routes of these NPs from production to end-user consumption until their end phase needs to be studied in detail and optimization of their suitable applications and controlled use to ensure environmental safety.

Concerns about environmental safety have led to strict regulations on the discharge of final brewery effluents into water bodies. Brewery wastewater contains huge amounts of organic compounds that can cause environmental pollution. The microalgae wastewater treatment method is an emerging environmentally friendly biotechnological process. Microalgae grow well in nutrient-rich wastewater by absorbing organic nutrients and converting them into useful biomass. The harvested biomass can be used as animal feed, biofertilizer, and an alternative energy source for biodiesel production. This review discusses conventional and current brewery wastewater treatment methods, and the application and potential of microalgae in brewery wastewater treatment. The study also discusses the benefits as well as challenges associated with microalgae brewery and other industrial wastewater treatments.

The article is devoted to the issues of industrial wastewater treatment using reagents received from productions wastes. The structure and properties of waste formed by production of titanium products containing ions of the titan, aluminum and iron are investigated. Modeling the process of receiving the reagent based on titanium sludge is made, its coagulating properties are investigated. During receiving process, modeling special att ention is paid to removal of the fl uorides, which are present at sludge. Effi ciency of the received titanic coagulant in comparison with known «Аква-АуратТМ30» reagent is shown. It is experimentally confi rmed that for production of a coagulant it is necessary to use the sludge, which is selected, in a place of its direct education. It is made a conclusion about the possibility of titanium sludge use for receiving reagent and its further use for purifi cation of industrial sewage.

Abstract To reduce demand and discharge, instead of industrial wastewater being poorly treated and disposed of, it can be recycled, reused, or recovered if it is properly managed, thus having a substantial decrease in the water requirement and environmental impacts. The challenge is to select the appropriate process or combination of processes to achieve this based on the wastewater quality. Consequently, the objective of this investigation is to review every technology from conventional through advanced, for reliable and sustainable wastewater treatment and derived sludges, focusing on advantages, disadvantages, and technical gaps for development. Even though there is a wide range of possible technologies, it was evinced that there is huge potential to exploit and make them economically and sustainably viable for waste processing and circular economy, even in the mature massively implemented wastewater treatment technologies in the industry. Overall, we identify that independently from the technology to be studied, the future investigations on every unit, especially on those not vastly implemented, should be focused on: (1) The capacity in removing selected pollutants and decreasing impurities, (2) energy efficiency, (3) environmental safety, (4) economic viability, (5) hybrid processes, and (6) sustainability by waste processing.
