Hunhu hwemvura yerwizi hunoongororwa neEnvironment Agency kuburikidza nechirongwa cheGeneral Quality Assessment (GQA) uye zvakakosha kuti makemikari anogona kukuvadza murwizi adzorwe. Amoniya chinhu chakakosha chinovaka muviri kumiti nealgae zvinogara mumvura yerwizi. Zvisinei, kana tembiricha yerwizi ikachinja, ammonia ine ion inoshanduka kuita gasi reammonia risingasanganisi ion. Izvi zvinouraya hove nezvimwe zvipenyu zvemumvura murwizi, saka zvakakosha kugara uchitarisa huwandu hweammonia.
Hunhu hwemvura hwakakoshawo kumafekitori ekuchenesa mvura anoshandisa mvura yerwizi senzvimbo yawo. Huwandu hwakawanda hweammonia mumvura hunogona kukonzera matambudziko makuru ekuuraya utachiona. Nekuyera huwandu hweammonia mumvura yerwizi zvinobudirira panopinda fekitari yekuchenesa mvura, sangano rinokwanisa kuchengetedza huwandu hwemvura inobuda. Mune zvimwe zvinoshandiswa, nzvimbo inobuda inogona kuvharwa kana huwandu hweammonia hwasvika padanho rakakwirira zvisingagamuchirwi.
Maitiro ekutarisa ammonia aripo iye zvino anodhura uye akaoma, anoshandisa ma electrode anosarudza ion uye ma reagents anodhura, ane chepfu uye akaoma kubata. Ma monitors aya haanawo kutsanangurwa uye anoda kuongororwa nguva dzose kuti aenderane nezvinodiwa zvakasiyana, zvakaita sekurapa mvura yakasviba, kurapwa kwemvura yekunwa uye kuyera huwandu hweammonia mumvura yerwizi. Ma electrode anosarudza ion anowanzoda zeroing zuva nezuva uye kuenzaniswa nema reagents.
Monitor yeHONDE ammonia inodzivirira matambudziko evaoni vekare veammonia nekushandisa nzira yakasiyana zvachose. Ammonia inoshandurwa kuita monochloramine compound yakagadzikana pahuwandu hwakaenzana nehuwandu hwepakutanga hweammonia. Huwandu hwechloramine hwakazoyerwa uchishandisa polarographic membrane sensor ine mhinduro yakasarudzika kune chloramine. Kemikari yeReaction inopa monitor kunzwa kwakanaka kunyangwe pahuwandu hwakaderera (ppb) hweammonia.
Reagent iri nyore, mutengo wakaderera uye mwero wekushandiswa wakaderera. Saka mutengo wekuva muridzi wayo wakaderera zvikuru.
Makambani makuru emvura muUK nemamwe marabhoritari ane mvumo yeEnvironment Agence atove kushandisa mamonitor eHONDE kuti vanyatsoongorora huwandu hweammonia mumvura yerwizi. Iyi sisitimu itsva yeammonia kubva kuAnalytica Technologies inopa vashandisi monitor iri nyore kushandisa, isingadhuri kutenga, inoshanda zvishoma uye isina kukanganiswa pakuyera.
