Izinhlelo zamanzi zokuphuza umphakathi zisebenzisa izindlela ezahlukahlukene zokwelashwa kwamanzi ukuhlinzeka imiphakathi yazo ngamanzi okuphuza aphephile. Izinhlelo zamanzi omphakathi zivame ukusebenzisa uchungechunge lwezinyathelo zokwelashwa kwamanzi, kufaka phakathi ukuphoqelelwa, ukugcwala, ukufundwa, ukufona kanye nokubulala amagciwane.
Izinyathelo ezi-4 zokwelashwa kwamanzi emphakathini
1.Ukuhlangana kanye ne-Floccation
Ekubambeni, amakhemikhali akhokhiswa kahle afana ne-aluminium sulphate, i-polyaluminum chloride noma i-ferric sulphate yethulwa emanzini ukuze inikeze amacala amabi aphethwe ama-solids, kufaka phakathi izinhlayiya ezingezinhle. Ngemuva kokuvikelwa amandla okukhokhiswa, izinhlayiya ezinkulu kancane ezibizwa ngokuthi ama-microflocs zakhiwa kusuka ekuboshweni kwezinhlayiya ezincane ngamakhemikhali angeziwe.
Ngemuva kokuhlanganiswa, ukuxubana okumnene okwaziwa ngokuthi i-flocculation kwenzeka, kubangele ama-microflocs ukushayisana nomunye futhi ahlanganise ndawonye ukwakha izinhlayiya ezivikelekile ezimisiwe. Lezi zinhlayiya, ezibizwa ngokuthi ama-flocs, qhubeka ukukhuphuka ngosayizi ngokuxuba okwengeziwe futhi ufinyelele usayizi omkhulu namandla, uzilungiselele esigabeni esilandelayo kwinqubo.
Isigaba sesibili senzeka lapho udaba omisiwe nama-pathogens ahlala ezansi kwesitsha. Uma amanzi ahlala isikhathi eside engaphazamiseki, ama-solids amaningi azonqotshwa amandla adonsela phansi bese ewa esitezi sesitsha. Ukubabaza kwenza inqubo yokudanga isebenze ngempumelelo ngoba yenza izinhlayiya zikhulu futhi zisinda, zibenze bacwile ngokushesha okukhulu. Ukuhlinzekwa kwamanzi omphakathi, inqubo yokudonsela phansi kumele yenzeke ngokuqhubekayo nakwimicengezo emikhulu yedimentation. Lolu hlelo lokusebenza olulula, olubiza oluphansi luyisinyathelo esidingekayo sokwelashwa ngaphambi kokuhlunga kanye nezigaba zokubulala amagciwane.
Kulesi sigaba, izinhlayiya ze-FLOC zizinze ezansi kokuhlinzekwa kwamanzi futhi amanzi acacile alungele ukwelashwa okwengeziwe. I-FILTRATION iyadingeka ngenxa yezinhlayiya ezincane, ezincibilikisiwe ezisakhona emanzini acwebile, ezibandakanya uthuli, ama-parasites, ama-virus, amagciwane kanye namagciwane.
Ekuhlutjweni, amanzi adlula ngezinhlayiya ezibonakalayo ezihlukahluka ngosayizi nokwakheka. Izinto ezisetshenziswayo ezivame ukusetshenziswa zifaka isihlabathi, amatshe amatshe namalahle. Ukuhlunga kwesihlabathi okuhamba kancane kusetshenziselwe iminyaka engaphezu kwengu-150, ngerekhodi eliphumelelayo lokususa amagciwane okubangela ukuphazamiseka kwesisu. I-Slow sand Filtration ihlanganisa izinqubo zebhayoloji, zomzimba, kanye namakhemikhali esinyathelweni esisodwa. Ngakolunye uhlangothi, i-Fast Sand Filtration iyindlela yokuhlanza umzimba ebonakalayo. I-Discoted futhi iyinkimbinkimbi, isetshenziswa emazweni athuthukile anezinsizakusebenza ngokwanele zokwelapha amanzi amakhulu. I-Rapid Sand Filtration iyindlela ekhuthele yezindleko ngokuqhathaniswa nezinye izinketho, edinga amaphampu asebenza ngamandla amandla, ukuhlanza njalo, ukulawulwa kokugeleza, umsebenzi onamakhono, namandla aqhubekayo.
4. Ukujezisa
Isigaba sokugcina enqubweni yokwelashwa kwamanzi emphakathini sibandakanya ukwengeza i-disinfectant efana ne-chlorine noma i-chloramine ekunikezelweni kwamanzi. I-Chlorine isetshenziswe kusukela ngasekupheleni kwawo-1800s. Uhlobo lwe-chlorine olusetshenziswa ekwelashweni kwamanzi yi-monochloramine. Lokhu kuhlukile kunohlobo olungalimaza ikhwalithi yomoya yangaphakathi ezungeze amachibi okubhukuda. Umphumela ophambili wenqubo yokubulala amagciwane ukukwenza uxidize futhi ususe udaba lwe-organic, oluvimbela ukusakazeka kwamagciwane, amagciwane, namagciwane angena ahlala emanzini okuphuza. Ukubulala amagciwane futhi kusebenza ukuvikela amanzi emajele kungavezwa ngesikhathi sokusatshalaliswa njengoba kupakelwa emakhaya, ezikoleni, emabhizinisini, nakwezinye izindawo.
"Ubuqotho, ubuqotho, obulukhuni, obusebenza kahle" ukunamathela isikhathi eside kwenkampani yethu emcabangweni, inzuzo ehambisanayo namakhemikhali okuhlanza amakhemikhali we-china, inkampani yethu yokuhlanza amanzi e-China, i-China futhi iThembe elifanelekile idala abathengi ngomgomo wokuwina.
China Wholesale China Pam,I-Cationic Polyacrylamide, ngokuhlanganiswa komnotho wezwe okuletha izinselelo namathuba embonini yezokuthuthwa kwezokuthuthwa kwemithi, ikhwalithi yethu yokuqala, ukuqiniseka okusha kanye nokuqiniseka ngokuzinikela kwamakhasimende aphezulu. Imikhiqizo, amanani ancintisanayo kanye nensizakalo enhle kakhulu, nangomoya wokuphakama, ngokushesha, ngokuqina, kanye nabangane bethu, qhubeka nokuyala kwethu ngekusasa elingcono.
