Uburyo bwo gupima imyunyu yimyanda ni ikibazo gihangayikishije buri wese. Igice nyamukuru gikoreshwa mugupima umunyu wamazi ni EC / w, igereranya ubworoherane bwamazi. Kumenya neza amazi birashobora kukubwira uko umunyu uri mumazi.
TDS (igaragarira muri mg / L cyangwa ppm) mubyukuri bivuga umubare wa ion zihari, ntabwo ziyobora. Ariko, nkuko byavuzwe haruguru, imiyoboro ikoreshwa kenshi mugupima umubare wa ion zihari.
Metero ya TDS ipima ubworoherane no guhindura agaciro kubisomwa muri mg / L cyangwa ppm. Imyitwarire nuburyo nuburyo butaziguye bwo gupima umunyu. Iyo upimye umunyu, ibice bikunze kugaragara muri ppt. Ibikoresho bimwe bitwara ibintu biza mbere-byashizweho hamwe nuburyo bwo gupima umunyu niba ubishaka.
Nubwo bishobora kugorana kubyumva, amazi yumunyu afatwa nkumuyoboro mwiza wamashanyarazi, bivuze ko mugihe ugerageza kubungabunga chimie ikwiye kubidukikije hanze, gusoma kwa EC / w bigomba kuba hejuru. Iyo ibi bisomwa bigabanutse cyane, birashobora kuba igihe cyo gufata amazi.
Ingingo ikurikira irareba neza umunyu nuburyo bwo gupima neza.
Umunyu w'amazi ni iki?
Umunyu bivuga ubwinshi bwumunyu ushonga neza mumubiri wamazi. Igice cyibanze gikoreshwa mu gupima imyunyu y’amazi ni EC / w, igereranya amashanyarazi y’amazi. Ariko, gupima umunyu wamazi hamwe na sensor ya conducitivite bizaguha urwego rutandukanye rwo gupima muri mS / cm, niwo mubare wa milisiemens kuri santimetero y'amazi.
Milimetero imwe Siemens kuri santimetero ingana na micro Siemens 1.000 kuri santimetero, naho igice ni S / cm. Nyuma yo gufata iki gipimo, igihumbi cya micro-Siemens bingana na 1000 EC, amashanyarazi y'amazi. Igipimo cya 1000 EC nacyo kingana n'ibice 640 kuri miliyoni, nicyo gice gikoreshwa mukumenya umunyu mumazi ya pisine. Gusoma umunyu kuri pisine yamazi yumunyu bigomba kuba 3.000 PPM, bivuze ko milisiemens kuri santimetero gusoma igomba kuba 4,6 mS / cm.
Nigute umunyu ukorwa?
Kuvura umunyu birashobora gukorwa muburyo butatu burimo umunyu wibanze, umunyu wa kabiri, hamwe nu munyu wa gatatu.
Umunyu wibanze nuburyo bukunze kugaragara, bibaho binyuze mubikorwa bisanzwe, nko gushiraho umunyu kubera imvura mugihe kirekire. Iyo imvura iguye, umunyu mwinshi mumazi uva mumazi cyangwa mubutaka. Umunyu urashobora kandi kunyura mumazi yubutaka cyangwa mubutaka. Amazi make nayo azatemba mumigezi ninzuzi hanyuma amaherezo mu nyanja no mubiyaga.
Kubijyanye nubunyu bwa kabiri, ubu bwoko bwumunyu bubaho iyo ameza yamazi azamutse, mubisanzwe biterwa no kuvana ibimera ahantu runaka.
Umunyu urashobora kandi kugerwaho binyuze mumunyu wa gatatu, bibaho mugihe amazi akoreshwa mubusitani nibihingwa hejuru yinzinguzingo nyinshi. Igihe cyose igihingwa kivomerewe, amazi make arahumuka, bivuze kwiyongera k'umunyu. Niba amazi yongeye gukoreshwa buri gihe, umunyu mubihingwa urashobora kuba mwinshi.
Kwirinda mugihe ukoreshametero yimikorere
1. Iyo upimye amazi meza cyangwa amazi ya ultrapure, kugirango wirinde gutembera kwagaciro kapimwe, birasabwa gukoresha igikonjo gifunze kugirango ukore ibipimo bitemba muburyo bwa kashe. Niba inzoga ikoreshwa mugupima no gupima, hazabaho amakosa manini.
2. Kubera ko indishyi yubushyuhe ifata coeffisente yubushyuhe ihamye ya 2%, gupima amazi y’ikirenga n’isuku ryinshi bigomba gukorwa nta ndishyi z’ubushyuhe bushoboka, kandi imbonerahamwe igomba kugenzurwa nyuma yo gupimwa.
3.Icyicaro cya electrode kigomba gukingirwa rwose nubushuhe, kandi metero igomba gushyirwa ahantu humye kugirango hirindwe amakosa yo gupimwa cyangwa gupima metero bitewe no kumena ibitonyanga byamazi cyangwa ubuhehere.
4. Gupima electrode ni igice cyuzuye, kidashobora gusenywa, imiterere nubunini bwa electrode ntibishobora guhinduka, kandi ntibishobora guhanagurwa na acide ikomeye cyangwa alkali, kugirango bidahindura electrode ihoraho kandi bigira ingaruka kumyizerere yikigereranyo cyibikoresho.
5. Kugirango hamenyekane neza niba ibipimo byapimwe, electrode igomba kwozwa kabiri n'amazi yatoboye (cyangwa amazi ya deionised) munsi ya 0.5uS / cm mbere yo kuyakoresha (electrode yumukara wa platine igomba gushirwa mumazi yatoboye mbere yo kuyakoresha nyuma yo gukama mugihe runaka), hanyuma kwoza namazi yipimishije inshuro eshatu mbere yo gupima.
