Disadvantages of the partition mixer of the corridor type are shown. Ways to increase and regulate the intensity and time of mixing reagents with source water in the transverse porous partitions themselves are outlined. It is shown that it is possible to improve the flow distribution in the live section of the mixer corridors due to the use of porous polymer concrete in the manufacture of transverse partitions, and also that the phase of per kinetic coagulation coincides with the period of \"rapid\" mixing of the coagulant with water, which significantly affects the effectiveness of the coagulation water purification.
 The first stage of research was carried out on a model of such a mixer on a scale of 1:4 with the aim of determining the local resistance of the porous partition. The porous partition is made of gravel with a size of 10...15 mm (average diameter 12.5 mm) and ED-20 brand epoxy resin with polyethylene polyamine (PEPA) hardener, approved by the Ministry of Health of Ukraine in domestic and drinking water supply systems.
 Experimental studies have shown that the local resistance of the porous partition is quite large, therefore it is proposed to perform a part of the corridor-type partition mixer in pressure mode, that is, to perform such a mixer in pressure mode or partially in pressure mode, depending on the location of the porous partition.","PeriodicalId":500744,"journal":{"name":"Pìdvodnì tehnologìï","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135001586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
