Theoretical and experimental study of mud injection porous drainage in filters with floating loading

The paper discusses up-flow filters with floating loading that intensify the process of filtering water for drinking purposes by improving filtering parameters and reducing power consumption. It is established that the problematic part of such filters are drainage systems. As a result of the analysis of drainage systems, it was found that the most promising material is porous polymer concrete. The proposed construction of drains is based on porous polymer concrete, which increases the reliability and durability of the filters with floating loading. The drainages based on porous polymer concrete, which intensify reliability and working life of filters, are offered. Mathematical model of the mud injection process of lower polymer concrete drainage with suspended matters, kept in damp water is designed. Experimental studies have shown the validity of the obtained model
