Izinhlelo zamanzi okuphuza zomphakathi zisebenzisa izindlela ezahlukene zokuhlanza amanzi ukuze zinikeze imiphakathi yazo amanzi okuphuza aphephile. Amasistimu wamanzi omphakathi ngokuvamile asebenzisa uchungechunge lwezinyathelo zokwelashwa kwamanzi, okuhlanganisa ukujiya, ukugeleza, ukucwiliswa kwenhlabathi, ukucwenga kanye nokubulala amagciwane.
Izinyathelo Ezi-4 Zokuhlanza Amanzi Umphakathi
1.I-Coagulation kanye ne-Flocculation
Lapho kuhlangana, amakhemikhali ane-positively charge efana ne-aluminium sulphate, i-polyaluminium chloride noma i-ferric sulphate yethulwa emanzini ukuze kuncishiswe izindleko ezingezinhle eziphethwe izinto eziqinile, okuhlanganisa ukungcola, ubumba, nezinhlayiya eziphilayo ezincibilikisiwe. Ngemva kokunciphisa ukushaja, izinhlayiya ezinkulu kancane ezibizwa ngokuthi ama-microfloc ziyakhiwa kusukela ekubopheni izinhlayiya ezincane ngamakhemikhali angeziwe.
Ngemuva kokuhlangana, ukuxubana okuthambile okwaziwa ngokuthi i-flocculation kwenzeka, okubangela ukuthi ama-microflocs ashayisane futhi ahlangane ukuze akhe izinhlayiya ezimisiwe ezibonakalayo. Lezi zinhlayiya, ezibizwa ngokuthi ama-flocs, ziyaqhubeka zanda ngosayizi ngokuxutshwa okwengeziwe futhi zifinyelele usayizi omkhulu namandla, ziwalungiselela isigaba esilandelayo kule nqubo.
Isigaba sesibili senzeka lapho udaba olumisiwe kanye namagciwane ehlala phansi esitsheni. Uma amanzi ehlala isikhathi eside engaphazamiseki, izinto eziqinile zizonqotshwa amandla adonsela phansi bese ziwela phansi esitsheni. I-coagulation yenza inqubo ye-sedimentation iphumelele kakhulu ngoba yenza izinhlayiya zibe zinkulu futhi zibe nzima, okubangela ukuthi zicwile ngokushesha. Ukuze kutholakale amanzi emphakathini, inqubo yokudilizwa kwenhlabathi kufanele yenzeke ngokuqhubekayo nasezitsheni ezinkulu zokudiliva. Lolu hlelo lokusebenza olulula, olushibhile luyisinyathelo esidingekayo sokwelashwa ngaphambi kwezigaba zokuhlunga nokubulala amagciwane.
3. Ukuhlunga
Kulesi sigaba, izinhlayiya ze-floc sezihlezi phansi emanzini futhi amanzi ahlanzekile alungele ukwelashwa okwengeziwe. Ukuhlunga kuyadingeka ngenxa yezinhlayiya ezincane, ezincibilikile ezisekhona emanzini ahlanzekile, ezihlanganisa uthuli, ama-parasites, amakhemikhali, amagciwane, nama-bacteria.
Ekuhlungeni, amanzi adlula ezinhlayiyeni ezibonakalayo ezihluka ngosayizi nokwakheka. Izinto ezisetshenziswa kakhulu zihlanganisa isihlabathi, amatshe namalahle. Ukuhlunga kwesihlabathi okunensayo sekusetshenziswe iminyaka engaphezu kwe-150, nerekhodi eliphumelelayo lokususa amagciwane abangela ukuphazamiseka kwesisu. Ukuhlunga kwesihlabathi okunensayo kuhlanganisa izinqubo zebhayoloji, zomzimba, kanye namakhemikhali esinyathelweni esisodwa. Ngakolunye uhlangothi, ukuhlungwa kwesihlabathi ngokushesha kuyisinyathelo sokuhlanza ngokomzimba. Iyinkimbinkimbi futhi iyinkimbinkimbi, isetshenziswa emazweni athuthukile anemithombo eyanele yokwelapha amanzi amaningi. Ukuhlunga isihlabathi ngokushesha kuyindlela ebiza kakhulu uma kuqhathaniswa nezinye izinketho, edinga amaphampu asebenza ngamandla, ukuhlanzwa okuvamile, ukulawula ukugeleza, umsebenzi onekhono, namandla aqhubekayo.
Isigaba sokugcina senqubo yokuhlanza amanzi emphakathini sifaka ukufaka isibulala-magciwane njenge-chlorine noma i-chloramine emanzini. I-chlorine isetshenziswe kusukela ngasekupheleni kwawo-1800. Uhlobo lwe-chlorine olusetshenziswa ekwelashweni kwamanzi yi-monochloramine. Lokhu kuhlukile kunohlobo olungalimaza ikhwalithi yomoya wasendlini ezungeze amachibi okubhukuda. Umphumela oyinhloko wenqubo yokubulala amagciwane iwukuba i-oxidize futhi isuse izinto eziphilayo, okuvimbela ukusabalala kwama-parasites, amagciwane, namagciwane angase ahlale emanzini okuphuza. Ukubulala amagciwane futhi kusiza ukuvikela amanzi emagciwane angase achayeke kuwo ngesikhathi esatshalaliswa njengoba ehanjiswa ngamapayipi ezindlini, ezikoleni, emabhizinisini nakwezinye izindawo.
