- W3044885306 abstract "Relevance of research Ukraine has an urgent problem of supplying adequate quality drinking water, especially in rural areas. Only 30% Ukrainian rural areas are equipped with water supplying systems. The main sources of water supply in local agricultural water pipelines are groundwater. However, groundwater in Ukraine is often characterized with a rather high iron content, which is sometimes ten times higher than the current regulatory requirements Cn = 0.2 mg / dm3.
 The purpose and objectives of the study For groundwater treatment we propose to use biological methods with the placement of treatment facilities in the body of the water tower (WT), which can significantly reduce capital and operating costs. When the downward movement of aerated source groundwater through the bioreactor (BR) a transition of divalent iron into a ferric iron form occurs with the help of iron bacteria, immobilized on fibrous media, and when the ascending movement of water through floating polystyrene foam media of the contact clarification filter (CCF), it is clarified from colloidal particles of iron hydroxide due to their compressed sedimentation in the subfilter space of the CCF.
 Research methods. The results of laboratory research on iron reduction when water deferrization for a certain period of time are given, the technological solution for the optimization of constructive and technological parameters of WT and CCF in the absence of repeated charging of the filter is offered. When a contact-clarifying filter is flushed it is recommended to leave a part of the Gmin residue, which will serve as a catalyst during the next water deferrization cycle.
 Prospects for research, directions for further work. We proposed a new automated water deferrization plant equipped with an elevated water tank. The advantage of it is to provide a high efficiency of biological water-based iron removal with complete automation of water filtration and filter flushing, while reducing the cost of its construction and operation." @default.
