The article is dedicated to analyzing the changes in museum design in the context of the rapid integration of digital technologies. It examines the ways of integrating multimedia systems, virtual and augmented reality into the architectural structure of museum spaces. Based on the analysis of domestic and foreign examples, new approaches to exhibition formation are identified, built on principles of flexibility, interactivity, and immersiveness. The emphasis is placed on the changes in typological models of museums: from traditionally hierarchical to adaptive, transformable formats. Special attention is given to the evolving role of the architect, acting as a mediator between digital scenarios and spatial expression. As a result, the museum of the future is envisioned as a complex spatial-technological ecosystem, in which architecture becomes an active participant in communication with visitors through digital content and technological interfaces.

The article presents a study of the hydrophysical properties of modified cement concretes, namely frost resistance and water resistance. The compositions of modified concretes for research are determined. It is established that the use of mineral fertilizer production waste in combination with the superplasticizer "Osnovit Safescreen SPP1" allows to increase the frost resistance, water resistance and strength of concrete composites.

The paper reveals the problem and causes of the formation of fetid compounds in the systems of transportation and wastewater treatment. Various methods used at the moment to eliminate and neutralize unpleasant odors, as well as a number of measures to clean the air from fetid compounds are considered. A new method is described to prevent the formation of odors of fetid compounds in wastewater transportation and treatment systems and a device for its implementation using low-intensity cavitation. The scheme of the device for sewage treatment from smells of fetid compounds. The principle of operation of this installation is described.

Keywords: fetid compounds , air purification, biological purification, low-intensity cavitation.
