Mvura yese yekunwa inocheneswa kubva kumvura yemutsime, inova dziva remvura yakachena, rwizi, tsime remvura, kana dzimwe nguva rwizi neMatsime emvura anogona kuve panjodzi yekusvibisa netsaona kana nemaune uye zvine chekuita nemamiriro ekunze kana shanduko yemwaka.Kutarisisa kwemvura yemhando yemvura saka kunoita kuti iwe utarise shanduko kune maitiro ekurapa.
Danho rekutanga: Pre-kurapwa kwechitubu chemvura, iyo inonziwo Coagulation uye Flocculation, zvimedu zvichabatanidzwa nemakemikari kuti zviumbe zvidimbu zvakakura, ipapo zvimedu zvakakura zvichanyura pasi.
Nhanho yechipiri ndeyeKusefa, mushure mekuita sedimentation mukurapwa kwekutanga, mvura yakachena ichapfuura nemumasefa, kazhinji, sefa inoumbwa nejecha, matombo, uye marasha) uye saizi yepore.Kuchengetedza mafirita, isu tinofanirwa kutarisa turbidity, yakamiswa yakasimba, alkalinity uye mamwe emhando yemvura paramita.
Nhanho yechitatu inzira yekuuraya utachiona.Danho iri rakakosha kwazvo, mushure mekusefa kwemvura, tinofanira kuwedzera mushonga wekuuraya utachiona mumvura yakasefa, senge chlorine, chloramine, hurongwa hwekuuraya utachiona hwasara, mabhakitiriya, uye mavhairasi, ive nechokwadi chekuti mvura yakachengeteka kana ichipinzwa kumba.
Nhanho yechina ndeyekugovera, isu tinofanirwa kuyera pH, turbidity, kuomarara, yakasara chlorine, conductivity (TDS), tobva taziva njodzi dzinogona kuitika kana kutyisidzira hutano hweveruzhinji nenguva.Huwandu hwechlorine hwasara hunofanirwa kunge huri pamusoro pe0.3mg/L painoburitswa kubva muchirimwa chemvura yekunwa, uye nepamusoro pe0.05mg/L pakupera kwepombi network.Turbidity inofanira kushomeka ne1NTU, pH kukosha kuri pakati pe6.5~8,5, pombi ichange ichiita ngura kana kukosha kwepH kuri kushoma 6.5pH uye chikero chiri nyore kana pH iri pamusoro pe8.5pH.
Zvisinei panguva ino, basa rekutarisa kwehutano hwemvura rinonyanya kutora kuongorora kwemaoko munyika dzakawanda, iyo ine kukanganisa kwakawanda kwekukurumidzira, kuzara, kuenderera mberi uye kukanganisa kwevanhu etc.BOQU online quality monitoring system yemvura inogona kutarisa kunaka kwemvura maawa makumi maviri nemana uye nguva chaiyo.Inopawo nekukurumidza uye kwakaringana ruzivo kune vanoita sarudzo zvichienderana nekuchinja kwemhando yemvura munguva chaiyo.Nekudaro kupa vanhu mvura ine hutano uye isina njodzi.
