Justification for use and structural schemes of water intake-purification facilities in drip irrigation systems

Abstract

Purpose: development of justification for the feasibility and possibility of application and structure schemes of filtering water intakes for water intake from canals, its preliminary purification and supply to drip irrigation systems. Materials and Methods. During development of justification, general and specific scientific methods of analysis and synthesis of information on the advantages and disadvantages of filtering water intakes were used, and during the development of their designs, technologies of research design were used. Results and Discussion. It has been found that filtering water intakes can simultaneously perform the functions of water intake, trash barriers, fish protection and purification facilities. Structural flexibility and simplicity of performance, environmental friendliness, multifunctionality and high technical and economic indicators are the basic characteristics that made it possible to substantiate the feasibility of their application as water intake and treatment facilities for drip irrigation systems. As a result of the research, at the level of inventions, structural schemes of water intake structures with inlets equipped with filter panels with bottom and slope locations were developed. The water intakes provide for the arrangement of catchment and water storage containers, ensuring the water collection seeped through the filter panels and its subsequent drainage into the water conducting stream. The water intake structures provide for the possibility of selective water intake from the least polluted horizons of the water flow. The problematic issues of the use of filtering water intakes are noted in terms of the need to create a developed water intake front and periodic flushing or replacement of filtering panels. Conclusions. The feasibility of using water intake purification facilities, providing water intake from water sources and its preliminary treatment for the needs of drip irrigation systems, has been substantiated, as well as filtering water intakes designs recommended for the arrangement and use in drip irrigation systems are proposed.
