Ukukhumbula Iphrojekthi Yokuhlanza Amanzi yasePhilippines

Enkabeni yedolobha le-Metro Manila, lapho inani labantu elingaphezu kwezigidi ezingu-13 libhekene nengcindezi enkulu yamanzi phakathi nokukhula ngokushesha kwezimboni kanye nezishingishane ezivamile, ukuphathwa kwamanzi angcolile kuyindlela ebalulekile yokuphila. IPhilippines ibhekene nokungcoliswa okukhulu okuvela emfucumfucwini engageziwe; 10% kuphela wamanzi angcolile asekhaya athola ukucutshungulwa, akhipha amathani angaphezu kwe-1,000kwei-biochemicalisidingo se-oxygen(BOD) nsuku zonke emigwaqweni ebalulekile yamanzi njengomfula i-Pasig, ngokuhlola koMnyango Wezemvelo Nezemvelo (DENR).

Ukuguquguquka kwesimo sezulu, okuhlanganisa isomiso esibangelwa u-El Niño kanye neziphepho zonyaka ezingu-20+, kuphazamisa uchungechunge lokuhlinzeka, kuyilapho uMthetho Wamanzi Ahlanzekile ka-2004 uphoqelela imikhawulo ye-Class C effluent (BOD <50 mg/L) ukuze kuvikelwe i-ecosystem. Isikhungo esishaqisayo samalitha ayizigidi ezingama-50 ngosuku (i-MLD) eDolobheni lasePasay, sisekelwa yiMaynilad Water Services kanye nezigidi ezingama-$145 ezivela eBhange Lokuthuthukiswa Kwase-Asia (i-ADB) kanye ne-Japan International Cooperation Agency (JICA), sibhekana nalezi zinsongo ngokwelashwa kwebhayoloji okuthuthukisiwe kanye nokuvuselelwa kwendle.

Lokhu kwandiswa kohlelo AMANZI AMASHA, okuqondiswe ekusetshenzisweni kabusha okuphuzwayo okungu-12 MLD ngasekupheleni kuka-2025, kubhekana nokuhlukahluka okunamandla kusuka emanzini asemadolobheni kanye nokukhishwa okungakahleleki, okuhlanganisa ukukhishwa kwezakhi ukuze kuhlangatshezwane naMazinga Kazwelonke Wase-Philippine Amanzi Okuphuza (PNSDW). Okubalulekile ekusebenzeni kahle kwayo ukumitha kokugeleza okunembile kwe-aeration kanye ne-dosing, laphoI-Sinomeasure'sI-SUP-LDGkazibuthei-flowmeterihambisaubuchwepheshe be-electromagnetic obungaphazamisi obusekelwe emthethweni we-Faraday wokusingatha imifudlana egcwele imfucumfucu ngokunemba okungu-±0.5%, ukunciphisa ukusetshenziswa kwamandla ngo-20% futhi kuvumela ukuthuthukiswa okuqhutshwa yi-SCADA. Lolu hlelo aluhambisani kuphela neziyalezo zokuvuselela i-Manila Bay kodwa luvula indlela yokuphinda kusetshenziswe ukungcola kwezolimo, kugqugquzelwa imodeli eyindilinga phakathi kwezidingo zokwelashwa ezihlongozwayo zika-2030 eziphindwe kabili.

Ukwakhela endimeni eqinile ekulandeleleni okunamandla, i-SUP-LDG Sanitary Electromagnetic Flowmeter (SUP-LDGS) ivela njengozakwabo wenhlanzeko, iqinisekisa uguquko oluphathwayo oluphathwayo ngokuphepha ekucutshungulweni kokudla kanye nokugeleza komsebenzi wemithi ngokunemba okungantengantengi nobunyumba.

Ukuhamba nge-Electromagnetic Flow Meter

Idizayinelwe uketshezi lwe-conductive ezindaweni ezihlanzekile, le flowmeter isebenzisa umgomo ofanayo wokungeniswa kuka-electromagnetic ngokudala i-voltage esuka kusivinini samanzi endaweni kazibuthe ukuze ilethe izilinganiso zevolumu engenazo izingxenye ezihambayo, inciphise ukushear nokungcoliswa kwezingozi ezinhlelweni ezibucayi.

Ithobelana nezindinganiso ze-EHEDG kanye ne-3-A, i-SUP-LDGS ihlanganisa izindlela ezimanziswa nge-electropolished 316L zensimbi engenasici kanye nezangaphakathi ezingenawo umfantu, ezilungele ukusakazwa kwangemva kokwelashwa endaweni yase-Philippine lapho amanzi abulawe amagciwane ephakela ukuhlanjululwa kwesiphuzo noma izintambo zokupholisa zobisi.

Ngebanga lokulinganisa le-DN15–DN1000 kanye nesivinini esisuka ku-0.2–15 m/s, livumela amanzi abuyiswe ngendlela ephansi ye-conductivity (≥5 μS/cm yemidiya engekho emanzini) ngaphandle kokwehla kwengcindezi, esekela imijikelezo ye-CIP/SIP efika ku-180°C ekucushweni kokuhlukaniswa. Imiphumela efana ne-4-20 mA, i-pulse, kanye ne-RS485/Modbus ihlanganisa kalula ne-SCADA ekhona, ihlinzeka ngokuxilongwa kwesikhathi sangempela ukuvimbela ukusimama eziteshini ezikhuthazayo.

Empeleni, i-SUP-LDGS ibhuloho umsuka wamanzi angcolile ekusetshenzisweni kabusha kwenani elingeziwe, okuhlanganisa ukuzibophezela kwe-Sinomeasure kumathuluzi aqinile, aguquguqukayo ahambisana nezinkambiso zenhlanzeko yomhlaba wonke kuyilapho kubhekwana nezinselele zasendaweni ezifana nokugeleza okubangelwa yizimvula ezinamandla.

Lapho ingena ngokujulile ekwazini kwayo ubunjiniyela, i-SUP-LDGS izigqaja ngochungechunge lwezicaciso eziqinisekisa ukwethembeka ekusetheni okudingayo kwenhlanzeko, njengoba kushiwo emibhalweni yezobuchwepheshe ye-Sinomeasure. Ukunemba kufinyelela ku-±0.5% wesilinganiso (noma ±2 mm/s ku-<1 m/s), ngokuphindaphinda okungu-0.2% kokudluliselwa kwesitokisi, okuqinisekisa ukulandeleka kokuthunyelwa kokudla okuhloliwe. Izinto ze-liner—PFA, F46, PTFE, FEP, noma i-neoprene—zinikeza ukumelana nokugqwala okuhambisanayo kwemidiya ye-pH 0–14, kuyilapho ukukhetha kwe-electrode (i-Hastelloy C-276, i-titanium, i-tantalum, noma i-platinum-iridium) ibekezelela izibulali magciwane ezinolaka ngaphandle kokucwiliswa.

Ukubekezelela izinga lokushisa loketshezi kusuka ku-20°C kuya ku-160°C, nokusebenza kwe-ambient kusuka ku--20°C kuya ku-60°C nokuvikelwa kwe-IP65/IP67 othulini nokucwiliswa. Izidingo zamandla zincane (AC 85–265V noma DC 24V), ukudweba <0.65W, futhi ukuguquguquka kokufaka kufaka phakathi i-flange (DIN/JIS/ANSI), i-clamp, noma izigaxa zentambo, ezinezintambo zekhebula ezifika ku-11mm. Izinhlobonhlobo ezivikela ukuqhuma (ExiaIICT6 Gb) zifanela izindawo eziguquguqukayo, futhi idizayini ye-modular yemitha ivumela izidluliseli ezikude zifike ku-50m, zenze ukunakekelwa esimweni sezulu esiswakeme sase-Philippine. Lawa mapharamitha, aqinisekiswa ngaphansi kwamazinga e-JB/T 9248-2015, agcizelela ubude beminyaka engu-10 be-electrode, izindlela ezidlula kude ezisetshenziswayo ezivame ukugqokwa kuma-viscous slurries njengokululama kwe-pulp.

Izici ezibalulekile ziphinde ziphakamise i-SUP-LDGS njengendawo yamandla enesondlo esincane sokulawula ukugeleza okunembayo. Ukuvuswa kwayo kwamafrikhwensi amabili kusimamisa amasignali ezimeni ezishaya ngamandla noma ezigeleza kancane, kususe umsindo ovela kumabhamuza noma izinto eziqinile ezivamile ekupholishweni kwamanzi angcolile, kuyilapho ulayini ongaconsi mshini uvimbela ukwakheka, unweba izikhawu zesevisi.

Ukutholwa kwepayipi elingenalutho okuhlanganisiwe kusetshenziswa ama-algorithms athuthukisiwe kumisa ukufunda okungamanga, nemisebenzi yokuzihlola, efinyeleleka ngephrothokholi ye-HART, amafulegi ama-electrode noma ukuphulwa kwe-liner kusenesikhathi, kunciphisa isikhathi sokuphumula esingahlelelwe ngokufika ku-30%. Ngobuhle benhlanzeko, ukufakwa kwe-tri-clamp okusheshayo okunqamula ngokushesha kunika amandla ukuqaqa okungenamathuluzi ukuze kuqinisekiswe, ukunciphisa isikhathi sokulungiselela ukuhlolwa, kanye nokungabikho kwezindawo ezifile kusekela ukuqinisekiswa okuyinyumba ngokweziqondiso ze-GMP.

Uma kuqhathaniswa namamitha e-ultrasonic, ukungezwani kwayo nokuhlukahluka kobuningingesikhathipHukulungiswaikhiqiza ukulawula okuqinile, ikhulisa isivuno ngo-5-10% ekusebenzeni kokuhlanganisa. Lezi zibaluli, zihlangene namandla okugeleza okukabili okuguquguqukayo okuguquguqukayo, zenza i-SUP-LDGS ingabi imitha nje kuphela kodwa ibe yimpahla esebenzayo ekuqinisekiseni ubuqotho bamanzi angcolile asuka ezimpompini zokuhlanza ze-Metro Manila kuya emigwaqweni ehlanzekile engezansi komfula.

I-SUP-LDGS ithola izinhlelo zokusebenza eziguquguqukayo kuzo zonke izimboni lapho ubuqotho bokugeleza kwenhlanzeko kubaluleke kakhulu, ikakhulukazi ohlelweni lokusebenzisa kabusha ukungcola kwephrojekthi yase-Philippine. Ekudleni nasesiphuzweni, iqapha izengezo zesithako njengamanzi e-syrup dilution noma ukupholisa kwe-post-pasteurization, igcina ukuvumelana kwe-batch phakathi kwama-viscosity ahlukahlukene afika ku-1000 cP.

Imigqa yezemithi iyazuza ekulandeleleni kwayo ekusabalaliseni amanzi ahlanzekile noma imbudumbudu yethebhulethi, ephakamisa amalogi athobela i-FDA ukuze athole izitifiketi zokuthekelisa. Ngaphandle kokwenziwa kobisi kukhulisa ubisi ukuze kumiswe ubisi, kuyilapho abakhiqiza utshwala belandelela ukugeleza kwe-wort emathangeni okuvutshelwa, kuyilapho benamathela ku-3-A yenhlanzeko.

Ezimweni zamanzi angcolile njengalesi sikhungo sase-Manila, yengamela ukufunwa kabusha kwemifudlana yokunisela nge-agro-irrigation, ukuvimbela ukuchelela ngokweqile okwandisa usawoti emasimini elayisi.

Imikhakha yamakhemikhali iwusebenzisela ukungcola okungashintshiwe kuma-reactors enqwaba, kanye nezimonyo zokuxuba i-emulsion, lapho ukulinganisa okunembile kunciphisa imfucuza. Ngokukhula kusuka esikalini selebhu ye-DN15 kuya ku-DN1000 yezimboni, kanye nezingcindezi eziya ku-1.6–4.0 MPa, isekela izinhlelo zokukhipha uketshezi olungenalo uketshezi ezindaweni ezisondelene nezimayini njenge-Cebu, ukubuyisela amanzi ahlanzekile ngaphandle kwezingozi ezincane. Ekugcineni, lokhu kusetshenziswa kuguqula amanzi ahlanziwe asuke umthwalo abe yinzuzo, aqhubekisele phambili ukusebenza kahle ezindaweni ezingenawo amanzi.
