“…In 2021, Abdibattayeva et al [72] designed a helio device, based on solar energy, and used it for a new treatment method to extract oil products from wastewater or solid waste. The following year, Ghouas et al [73] succeeded to remove VOC from aqueous solutions using the cloud point extraction and a biodegradable nonionic surfactant.…”

This review paper aims to analyze studies conducted over recent years (2011–2021) on hydrocarbon pollution in the Danube’s Romanian sector. This involves looking at three main issues: Space-related Romanian Danube hydrocarbon pollution; the nature of samples and the types of tests used for hydrocarbon authentication; hydrocarbon effects on bioindicators and fish cell lines. The papers extracted for this review were selected from three scientific article platforms: Web of Science, Science Direct, and Google Scholar, by using keywords, a specific search protocol and various selection filters. The main results of the present analysis are the following: the highest levels of hydrocarbon contamination in suspended particulate matter and sediments were found in the sector Iron Gates-Călărași (2013), and the main pollution sources were industry, navigation and wastewater discharges; sediment and biological samples accumulate higher concentrations of hydrocarbons than water samples, and are a good indicator for these pollutants’ presence; the most widely used bioindicators are aquatic worms, mollusks, crustaceans, the wild common bleak, and, in the laboratory, fish cells; various methods are used in order to confirm hydrocarbon presence and/or their effects on biota: fluorescence, comet assay technique, micronucleus test, complementary passive samplers, in vitro bioassays, fugacity-based calculation model, sensors, oil spill modeling.

Crude oil is considered the main source of energy worldwide. Important problems faced by oil transportation methods are spills and unintended releases. Therefore, most technological developments in the field of transportation methods are aimed at reducing emissions, improving efficiency or preventing spills and leaks. Pipeline systems are the safest, most efficient and economical way to transport crude oil. The transportation process suffers from serious problems, such as: asphaltene and paraffin interacting with the structure damages it, pressure drop in the pipes and high energy consumption during pumping. One of the most important economic tasks when transporting oil through a pipeline is to maintain fluidity and reduce the pressure drop along the pipe. This article highlights the latest and most effective development methods that were used to increase the fluidity of crude oil in pipelines, and also examines the possibilities of reducing energy costs for transporting heavy oils and hydraulic resistance of pipelines by creating intermediate solar station devices consisting of a parabolocylindrical concentrator with a tracking system and a solar panel with a converter that increase the safety and environmental friendliness of oil transportation by reducing the risk of accidents. The intermediate solar station uses a renewable energy source and is clean from an environmental point of view, since it does not produce harmful emissions. The use of solar energy as a green alternative to traditional energy carriers makes it possible to increase the productivity of the pipeline by up to 50 %, eliminate energy costs during oil transportation.

“…There are a large number of natural sorbents used to solve water treatment problems, such as quartz sand, activated carbon, chitosan, jute, cellulose, sawdust, bentonite clay, etc. The most common sorbent in domestic and foreign practice for deep purification of drinking water is activated carbons: granular and powdered [11]. But the use of such traditional sorbents in wastewater treatment, in the presence of specific contaminants in the source water, does not provide a guaranteed water quality that meets sanitary rules and regulations.…”

“…An analysis of modern literature [ [6], [7], [8], [9], [10], [11], [12], [13]] showed a significant increase in the rate of publications devoted to the study of numerous modifications based on zeolites with the introduction of metal nanoparticles and the scope of the corresponding sorption and catalytic systems. The high surface energy of nanosystems makes them especially attractive for use in many catalytic industries since this property makes it possible to carry out technological processes under milder conditions than traditionally accepted ones.…”

The activities of industrial enterprises in ferrous and non-ferrous metallurgy and other industries lead to environmental pollution with wastewater containing harmful substances that, even in small quantities, have a rather serious negative impact on human health and the state of the biosphere. There are a large number of natural sorbents used to solve water treatment problems. Among inorganic sorption materials, zeolites are widely used in practice. These natural materials have thermal and radiation stability and high selectivity. The purpose of this article is to study the sorption capacity of zeolites modified with nanostructured rare metals in several ways, with different options for activating the matrix to improve sorption properties with respect to ions of heavy and non-ferrous metals. Based on the experiments conducted, it was proven that zeolites modified with vanadium and titanium nanocompounds are highly effective in removing heavy metal ions from wastewater. The resulting composition on a zeolite matrix creates a highly dispersed solid phase of nanoparticles in the form of a sol-gel. Such systems have an excess of energy, which leads to increased reactivity and adsorbing properties. It is obvious that the activation of zeolites makes it possible to obtain a wider range of active centers of different nature. This determines the varied use of zeolites in the technological system for treating wastewater from heavy and non-ferrous metal ions, which will make it possible to achieve MPC standards.
