The serious salinization of farmland soil and the shortage of water resources in arid areas are becoming more and more serious; In order to solve the problem of shortage of fresh water resources, find a resource that can be converted into fresh water; Brackish water is derived from farmland saline alkali land. Brackish water desalination technology has increased interest in scientists' research. However, brackish water can be used as an effective substitute for freshwater conversion because of its low salt concentration and can also be widely used in many water deficient countries. However, partial or total desalting of brackish water is essential to meet the water quality requirements of production and life. The selection of appropriate water resources desalination technology needs to understand the operation methods and technical means of the existing brackish water desalination process. Proper combination of desalination technologies can improve the efficiency of brackish water desalination. This review provides the latest advances in data, materials and categories that can help select and design requirements for specific applications.

Today modular construction is gaining popularity in the arrangement of production facilities. The purpose of the research is the theoretical substantiation of the choice of the optimal thickness of thermal insulation for external protections of modular buildings taking into account the evaluation criteria based on the method of hierarchy analysis. The article reflects the possibility of using modular buildings for residential and public needs. Given the peculiarities of the use of thermal insulation materials, such structures are erected in a short period of time due to the use of ready-made modules. It is also proposed to use multicriteria analysis to compare different thicknesses of thermal insulation of a modular building. The obtained results are presented in the form of petal diagrams and diagrams of global priorities, which made it possible to make an in-depth assessment of several thicknesses of thermal insulation. When conducting theoretical research, it should be noted that the importance of each of the criteria was taken into account for the selection of thermal insulation. An expert assessment was performed to determine the thickness of thermal insulation, which can be used for lightweight prefabricated structures of modular buildings. As a result of research, it was found that the most suitable thermal insulation material is polyurethane.

Main Strategy

Food waste (FW) has a high potential for use in biological processes such as anaerobic digestion (AD), especially due to its high content of biodegradable organic matter. To inoculate the reactors, sludge is usually used. The sludge should ideally have good sedimentation and specific methanogenic activity (SMA), which is typical for granular sludge. However, in a Latin American context, the most available and accessible sludges are flocculants with low sedimentation and SMA. Applying technological surveillance between 1975 and 2017, using multicriteria analysis techniques such as analytical hierarchy process (AHP), and consulting with international and national experts, we observed that there were few studies, compared to published studies on the substrates that focused on improving inoculum quality through conditioning to improve its characteristics and maximize methane production. The inoculum-conditioning methodologies identified were grouped into five categories, being the main strategy the addition of nutrients followed by anaerobic digestion with an easily degradable substrate. However, extension of technological surveillance is recommended by incorporating the results published from significant events in the field of anaerobic digestion, such as the Latin American Workshop and Symposium on Anaerobic Digestion and the World Congress on Anaerobic Digestion.

The choice of the most beneficial road alignment variant is a multicriteria issue, based on transport, economic, social and environmental criteria. The criteria chosen for a multicriteria analysis can be expressed through measurable or immeasurable parameters. In order to compare and assess the variants it is necessary to normalize the criteria, which means a rescaling of their value, so that the criteria values fall into a specific range. The main aim of normalization is to assign an identical weight to each criterion in relation to other criteria. This article presents a review of the influence of criteria normalization methods and the variant assessment methods on the choice of the most beneficial road alignment variant on the example of the bypass of the town of Księżyno, which is a stretch of Regional Road 678 near Bialystok. Four variants of road alignment were compared and their ranking was created using six assessment methods. It was proven that the choices of the criteria normalization method as well as the variant assessment method both have signifi­cant influence on the result of the multicriteria analysis in the decision-making process of selecting the road alignment.

Although there is technical information on the efficiency of advanced oxidation technologies (TAOs) at the laboratory level, in some cases at the pilot level and few on a large scale, it is not easy to select the most appropriate technology for an effluent, since the selection of technology depends on the characteristics of the contaminated water. Through the application of the multicriteria analysis technique, this article proposes a scale of TAOs for the complementary treatment of water contaminated with contaminants emergent (CE). The chosen alternatives were the technologies with peroxide (H2O2), Ozone (O3) and Fenton (Fe/H2O2) processes, the evaluation criteria were electric energy consumption (EEO), technological maturity level, complexity of design / operation and cost of operation. The technology most recommended by AHP is ozone and peroxide / UV with a difference of 8.6% in the frequency in the evaluation of the criteria. For the AHP-TOPSIS methodology, peroxide / UV is the key technology over ozone with a difference of 31.4% in the frequency of selection.
