Black grit papombi harisi iro dambudziko

Zvakadaro, grit yauri kuona inogona kunge iri chimwe chinhu. Tichifunga kuti urikungoona matinji matema chete kana uchinge wagara uchipukuta pombi uye kugeza musoro., madhipoziti anogona kunge ane oxidized manganese, chicherwa chinowanzo kuvepo muhuwandu hunyoro pamwe nesimbi mumvura inopedza. Imwe neimwe inogona kunhongwa nekuti mvura inofamba nenzira yevhu nematombo, kunyange simbi ichikwanisa kubva papombi dzinoora dzakagadzirwa nerata. Nzvimbo iyo mvura inorova mhepo - pane aerator yepombi yekicheni kana pamusoro wekugeza, semuenzaniso - zvicherwa zvinosanganiswa neokisijeni. Oxidized iron inogadzira iyo yero kana tsvuku madhipoziti isu tese tinoziva se ngura; oxidized manganese ishava kana dema. Izvo zvimedu zvinogonawo kugadzikana kana girazi remvura radururwa. Kazhinji, pamwe chete negritty oxidation, panogona kuva nekuwedzera slime nhema, izvo zvinokonzerwa ne microorganism inodya pane oxidized iron uye manganese.

Imwe simbi kana manganese mumvura haisi nyaya, uye kunyange chidimbu cheslime haisi njodzi yehutano. (Asi kana izvo zvinokukuvadza, O'Brien anokurudzira kuichenesa nemhinduro yakapfava yebleach.) Iron uye manganese akakosha chaizvo pakugara zvakanaka - muhuwandu hunoratidza. Kunyanya kuwanda kunogona kuve njodzi yehutano, uye inogona kuita kuti chimiro chemvura chivavave uye chine mavara, dzimba dzokugezera nekuwachira. Iyo Environmental Safety Kambani haina muganhu unodiwa kune ese ari maviri iron kana manganese, zvisinei inoratidza kuti iron ive pasi 0.3 mamilligrams parita uye manganese ive pasi 0.05 mg/L kudzivirira mukupikisa maitiro ane ngozi uye kumaka.

Arlington mvura inobva kuWashington Aqueduct nenzira yeDalecarlia Water Remedy Plant. Iyo Washington Aqueduct murabhoritari inoongorora yakakura kupfuura 65,000 masampuli emvura gore rega rega uye nyaya dzinowanikwa pairi website. The the 2018 Chirevo chinoratidza mwedzi-kusvika-mwedzi kuyedzwa kwemanganese kutanga kubva 0.5 zvikamu pabhiriyoni kusvika 1.4 ppb, avhareji kunze 0.77 ppb, kuenzana kwe 0.00077 mg/L - ingangoita maodha maviri ehukuru pasi peEPA inokurudzirwa nhungamiro ye 0.05 mg/L.

Iwe unogona kunge uine isiri yeruzhinji zvinobudirira, zvisinei, danho remanganese rinogona kuwedzera. Yakawandisa manganese inowanzowedzera pasina mubvunzo mumvura inobudirira pane mumvura yepasi. Varidzi vedzimba dzematsime avo pachavo vane mhosva yekuedza mvura yavo pachavo uye nekuirapa kana vachisungirwa. The Virginia Cooperative Extension ine chinyorwa chakanzi “Virginia Mhuri Yemvura Yepamusoro Chirongwa chemhando yepamusoro: Iron uye Manganese muMvura yemhuri" inotsanangura matambudziko uye inokurukura nzira dzekugadzirisa mvura kubvisa simbi yakawedzerwa kana manganese.. Izvo zvinopedzwa nekubatanidza phosphate kuchengetedza zvicherwa zvakamiswa mukati memvura kana nekuisa mune ion shanduko yekunyorovesa mvura..

Danho rokutanga, kunyange, inogona kuve kuti mvura yako iongororwe kana ichibva kune zvinobudirira. Iyo Virginia Cooperative Extension inotsigira iyo Virginia Family Mvura Yemhando yepamusoro Chirongwa (wellwater.bse.vt.edu), iyo inomhanyisa makiriniki mumatunhu mazhinji eVirginia anobvumidza varidzi vedzimba zvinobudirira kuti mvura yavo iongororwe neVirginia Polytechnic Institute neVirginia State College., wana nyaya dzakavandika maererano nezvakabuda uye dzidza kudzidudzira pamisangano inotevera. Izvi zvinotarisa cowl iron uye manganese, kuwedzera kune nitrate, tungamira, Arsenic, fluoride, sulfate, pH, yakazara yakanyungudika yakaoma, kuomesa, sodium, Copper, yakazara coliform micro organism uye E. coli micro organism.

Mvura chaiyo mune zvimwe zvikamu zveVirginia ine yakawandisa manganese nesimbi, zvisinei kusviba uko dzimwe nguva kunoita kuti varidzi vedzimba vaongororwe sezviri pachena hakuna kumbonetsa muArlington County.. "Ini handiyeuke ndichiyedza muArlington zvine manganese,” akadaro mumwe chipangamazano weBurke, Va., nzvimbo yebasa yeMvura Testing Labs (800-200-5323; wtlmd.com), iyo ine matatu ekuyedza maLab muMaryland uye imwe muVirginia inoshumira yakakura kupfuura 1,000 mapurogiramu emvura.
