The subject of this study - patterns of mutual influence on each other foundations that are located on water-saturated soil stratum of finite thickness with feature creep on modified ultrafiltration membrane for removal of organic substances, the methods of calculation of vertical settlers. The stress - strain state of the layer of finite thickness and napupulot significantly different (in a layer of finite thickness the stress concentration and sharper attenuation of soil subsidence outside the loaded region than in the framework of the design scheme napupulot). The problem of accounting for the influence of adjacent foundations in dense urban areas on rainfall each other partially solved, in particular, it is unknown how boundary conditions affect the soles of the layer on values of drawdown are shown; as shown in the calculation of drawdowns to take into account the processes of filtration consolidation and creep of soil skeleton, occurring at the base. Developed numerical models and packages of applied programs (codes) for the first time allow the designer to calculate the mass transfer process in vertical settling tanks and determine the efficiency of treatment, with regard to the geometric forms of these structures. When carrying out computational experiments based on the constructed models it is possible to assess the effectiveness of water treatment in vertical settling tanks taking into account the structural features of these structures - the existence of a Central pipe with a divider, partition, Weir, placed inside the sump, etc. a Distinctive feature of application of the developed models in practice is the efficiency in obtaining the calculated data in the simulation of the process of mass transfer in the tank: calculation time based on the two-dimensional model is of order 5, and on the basis of three-dimensional approximately 1 min. The developed model of a clogged pore from the perspective of the theory Poises. Experimental substantiation of application of the theory, for the calculation process of modifying the permeability of membranes in the purification of wastewater from organic substances.
