Ibikoresho byo gutunganya amazi byishingikiriza cyane ku gupima amazi neza kugira ngo bigenzure neza uburyo akoreshwa, kubahiriza amategeko, no gukoresha neza umutungo kamere. Mu ikoranabuhanga ritandukanye ryo gupima amazi riboneka, ibipimo by'amazi akoreshwa mu ikoranabuhanga (EM) biratandukanye kubera ubushobozi bwabyo mu gukoresha amazi—bitewe n'ubushobozi bwabyo bwo gufata amazi atwara amazi, kugabanuka k'umuvuduko muke, no kudakenera kuyabungabunga cyane. Ariko, guhitamo ibipimo by'amazi bikwiye mu gihe runaka cyo gutunganya amazi bisaba gusuzuma witonze ibipimo bya tekiniki, imiterere y'imikorere, n'ibisabwa kubahiriza amategeko. Iyi nyandiko igaragaza ibintu by'ingenzi kugira ngo byoroshye uburyo bwo guhitamo.
1. Sobanukirwa n'ibisabwa by'ingenzi mu gukoresha amazi mu gusukura
Mbere yo gusuzuma ingero za EM, ni ngombwa kumenya ibyo ikoreshwa rikeneye. Imikorere yo gutunganya amazi—kuva ku mazi mabi akoreshwa n’ayo akoreshwa kugeza ku kuyakuraho no kuyasohora—itandukaniro rigaragara mu miterere y’amazi n’ibyo akenera mu mikorere. Tangira ugaragaza:
- Ibiranga amazi: Uburyo amazi atwara umuvuduko ntabwo bushobora kuganirwaho kuri metero za EM (zikenera amazi afite ubushobozi bwo gutwara umuvuduko wa ≥5 μS/cm, ibyo bikaba byoroshye kugerwa n'amazi menshi, harimo amazi yo mu robine, amazi yanduye, n'amazi akoreshwa mu binyabutabire). Ariko, menya niba amazi arimo ibintu bikomeye bihagaze (urugero, umwanda mu buryo bwa kabiri) cyangwa ibindi bintu bitera kwangirika (urugero, chlorine, alum), kuko ibi bigira ingaruka ku guhitamo ibikoresho.
- Ingano y'amazi anyura: Menya igipimo cy'amazi make n'igipimo ntarengwa cy'amazi anyuramo icyuma gipima. Ibipimo bya EM bifite igipimo cy'amazi anyuramo (amazi menshi anyuramo kugeza ku gipimo gito cy'amazi anyuramo) ubusanzwe kiri hagati ya 10:1 na 100:1; hitamo igipimo gihuza ihindagurika ry'amazi (urugero: amazi menshi anyuramo mu gihe cy'imvura kugira ngo amazi yanduye asukurwe).
- Ibikenewe mu buryo buboneye: Amabwiriza agenga imikorere (urugero, amabwiriza ya EPA mu mabwiriza ya Leta Zunze Ubumwe za Amerika cyangwa EU Water Framework Directive) akunze gutegeka urwego runaka rw'ubuziranenge—ubusanzwe ± 0.5% kugeza ± 1% by'uburyo bwose bwo kugenzura ibikorwa, n'uburyo bwo kwihanganira cyane (± 0.2%) bwo gutanga raporo ku kwishyura cyangwa gutanga raporo ku bicuruzwa.
2. Shyira imbere uburinganire bw'ibikoresho kugira ngo birambe igihe kirekire
Ibice byatose bya EM metre (igice cy'umuyoboro wo gupimisha n'amashanyarazi) bihura neza n'amazi arimo gusukurwa. Gukoresha ibikoresho bidahuye bishobora gutera ingese, kwangirika, cyangwa se no kwangirika kwa meter.
- Gupima umuyoboro w'amazi: Ku mazi asanzwe yo mu ifumbire cyangwa amazi yanduye adashonga, imiyoboro ya kabutura (urugero: EPDM, neoprene) irahendutse kandi iraramba. Ku mazi ashyushye cyane (urugero: amazi yanduye aside cyangwa amazi afite chlorine nyinshi), hitamo imiyoboro irwanya imiti nka PTFE (Teflon) cyangwa FKM (Viton). Ku bijyanye n'ibintu bikomeye (urugero: umwanda), hitamo imiyoboro ikomeye (urugero: polyurethane) kugira ngo idasaza.
- Electrode: Electrode z'icyuma kidashonga (316L) zikora neza mu mazi menshi adashonga. Ku mazi ahumanya (urugero: amazi y'umunyu cyangwa amazi afite ibyuma biremereye), hitamo electrode za Hastelloy C cyangwa titanium. Mu mazi akunda kwanduzwa (urugero: amazi mabi yuzuye algae), tekereza kuri electrode zifite imiterere yo gusukura (urugero: gukaraba hakoreshejwe ikoranabuhanga cyangwa ikoranabuhanga) kugira ngo zigumane ubuziranenge.
3. Hitamo ubwoko n'ingano by'uburyo bwo gushyiramo
Ibipimo bya EM biraboneka mu buryo butandukanye bwo gushyiraho, kandi guhitamo gikwiye bitanga umusaruro wizewe kandi byoroshye kubungabunga:
- Gushyiramo umurongo: Ubwoko busanzwe bwo gutunganya amazi, aho icyuma gishyirwa mu muyoboro. Menya neza ko umurambararo w'umuyoboro uhuye n'ingano yacyo (urugero: metero 2 ku muyoboro wa santimetero 2) kugira ngo wirinde kugoreka kw'amazi. Nanone, kurikiza amabwiriza y'uwakoze umushinga w'amazi yerekeye uburebure bw'umuyoboro ugororotse (ubusanzwe uburebure bw'umuyoboro ugororotse bwa 5 × hejuru na 3 × hasi) kugira ngo ugabanye umuyaga uturuka ku nkokora cyangwa ku mashini.
- Gushyiraho ubwoko bw'imiyoboro: Bikwiriye imiyoboro minini (≥ santimetero 25) aho metero zishyirwa ku murongo zidakora. Ibipimo byo gushyiramo imiyoboro bishyirwa binyuze mu mwobo uri ku rukuta rw'umuyoboro, bigagabanya ikiguzi cyo gushyiraho n'igihe cyo kuruhuka. Ariko, bisaba gushyira hagati neza kugira ngo harebwe neza ibipimo, bityo hitamo moderi zifite uburebure bushobora guhindurwa bwo gushyiramo.
Ingano y'umuyoboro ni ikindi kintu cy'ingenzi: metero ntoya zishobora gutuma umuvuduko ugabanuka cyane, mu gihe metero ntoya zishobora kunanirwa gupima neza umuvuduko muto w'amazi. Buri gihe huza ingano y'umuyoboro n'ingano y'umuyoboro, cyangwa ubaze uwakoze uwo muyoboro kugira ngo akubwire inama niba ingano y'amazi iri hanze y'ubushobozi bw'ingano isanzwe.
4. Suzuma umusaruro n'ibiranga itumanaho
Ibikoresho byo gutunganya amazi akenshi bihuza ibipimo by'amazi na sisitemu za SCADA (Supervisory Control and Data Acquisition) cyangwa PLC (Programmable Logic Controllers) kugira ngo bigenzurwe mu buryo bwihuse kandi bigenzurwe. Bityo, ubushobozi bw'ibipimo n'itumanaho ni ingenzi:
- Umusaruro wa analogi: Ikimenyetso cya 4-20 mA ni cyo gisanzwe cyo kohereza umuvuduko uhoraho ku bagenzura. Menya neza ko umusaruro uvanywe mu mwanya umwe kugira ngo hirindwe ko ibikoresho biva mu mashanyarazi bibangamira amashanyarazi.
- Ibisohoka mu buryo bw'ikoranabuhanga: Ku bijyanye no kubika amakuru cyangwa gukurikirana amakuru ari kure, hitamo ibipimo bifite itumanaho rya RS485 (Modbus RTU) cyangwa Ethernet (Profinet, Ethernet / IP). Izi protocole zemerera ibipimo byinshi guhuza na sisitemu yo hagati, byoroshya imicungire y'amakuru.
- Ibindi bikoresho: Shaka ibipimo bifite ecran zo mu gace runaka (LCD cyangwa LED) kugira ngo usome aho hantu, hamwe n'imikorere y'ibitangaza (urugero: ibimenyesha ko amazi atemba cyane/ake, ibimenyesha ko amashanyarazi yangiza) kugira ngo ubashe kubibungabunga vuba.
5. Tekereza ku kubahiriza amategeko no kwemeza
Ibikorwa byo gutunganya amazi bigengwa n'amategeko akomeye, bityo icyuma gipima amazi cyatoranijwe kigomba kuba cyujuje ibyangombwa bisabwa:
- Ibyemezo by'ubunyangamugayo: Ibipimo bigomba kubahiriza amahame mpuzamahanga nka ISO 4064 (ku bipimo by'amazi) cyangwa IEC 60044-1 (ku bipimo by'amashanyarazi) kugira ngo birebe ko ingero zabyo zemewe n'amategeko.
- Impamyabushobozi z'umutekano n'ibidukikije: Ku bice biteje akaga (urugero, inganda zitunganya amazi yanduye zifite imyuka itwika), hitamo ibipimo bifite impamyabushobozi za ATEX cyangwa IECEx. Ku bijyanye no gukoresha amazi meza, menya neza ko ibikoresho bitose byujuje ibisabwa na NSF/ANSI 61 (US) cyangwa WRAS (UK) mu bijyanye n'umutekano w'amazi yo kunywa.
6. Ingano y'Ikiguzi cy'Ubutunzi (TCO)
Nubwo ikiguzi cyo kwitabwaho mbere y'igihe ari ikintu cyo kwitabwaho, TCO—harimo no kuyishyiraho, kuyisana, n'igihe izakomeza—itanga ishusho nyayo y'agaciro. Ibipimo bya EM muri rusange ntibikenera gusanwa cyane (nta bice byimuka bigomba kwangirika), ariko tekereza kuri ibi bikurikira:
- Ikiguzi cyo gushyiraho: Ibipimo byo gushyiramo imiyoboro bishobora gusaba gukata imiyoboro no kuyihagarika, mu gihe ibipimo byo gushyiramo imiyoboro byihuta kuyishyiraho.
- Ibikenewe mu gupima: Abakora benshi batanga inama yo gupima buri mwaka, ariko hari ubwoko butanga uburyo bwo kwipima kugira ngo bigabanye ikiguzi.
- Igihe cy'ubuzima: Ibipimo bya EM byiza cyane bifite ibikoresho bihuye nabyo bishobora kumara imyaka 10-15, bigatuma biba ishoramari ry'igihe kirekire.
Umwanzuro
Guhitamo igipimo cy’amazi gikwiye cyo gutunganya amazi bisaba uburinganire mu bijyanye n’ikoranabuhanga, ibikenewe mu mikorere, no kubahiriza amategeko. Mu gushyiraho ibisabwa by’ingenzi, gushyira imbere guhuza ibikoresho, guhitamo ubwoko bukwiye bwo gushyiraho, gusuzuma imikorere y’itumanaho, no gusuzuma TCO, ibigo bitunganya amazi bishobora kwemeza ko bishora imari mu gipimo cy’amazi gitanga imikorere nyayo kandi yizewe mu myaka iri imbere. Hamwe n’igipimo cy’amazi gikwiye, ibigo ntibishobora kuzuza gusa amahame agenga imikorere ahubwo bishobora no kunoza imikorere no kugabanya ikiguzi cy’imikorere—intego z’ingenzi mu isi y’ubu ibura amazi.
