ABSTRACT: In the article the authors give an attempt to evaluate the assessment of ecological efficiency and energy efficiency of one of the most promising technologies of realization of the construction industry enterprises' emissions cleaning process via hydrodynamic method with the use of foam which in the active zone of cleaning process realization can have either the foamy aerosol form (discrete bubbles), or a foam layer (where bubbles are located closely to each other and share common liquid film sides). Thus, the authors analyze physical essence of hydrodynamic method of ventilating air purification exhaust gases from polluting substances (toxic components) using the foam method with foam layer application or foamy aerosol and as a result receive parametrical dependences for the energy efficiency parameter and efficiency of air purification process in case of each method application. The authors present the results of the carried-out calculations graphically.
