Njengoba ukwanda kokucindezeleka kwemithombo yamanzi emhlabeni wonke kuqhubeka, ubuchwepheshe bokwelapha amanzi angcolile buye bathandwa kakhulu.Imishini yokwelapha amanzi amdaka ehlanganisiwe ye-PPH, njengesixazululo sokwelapha amanzi amdaka esisebenza kahle nesinobungani nemvelo, sisetshenziswe kabanzi ekhaya nakwamanye amazwe.
Ukuthuthukiswa kanye nokuvela kwemishini yokwelapha amanzi amdaka ehlanganisiwe ye-PPH kungalandelelwa emuva ngawo-1970. Ngaleso sikhathi, ngentuthuko esheshayo yokukhula kwezimboni kanye nokuhlala emadolobheni, ukwelashwa kwendle kwaba yinkinga enkulu yemvelo.ukwelashwa kwendleizindlela zivame ukusebenzisa izindlela zomzimba nezamakhemikhali, ezinokusebenza okuphansi kokwelapha kanye nokusetshenziswa kwamandla aphezulu. Ukuze kuxazululwe le nkinga, abacwaningi baqala ukuhlola indlela esebenza kahle futhi enobungani nemvelo.ukwelashwa kwamanzi amdakaubuchwepheshe.
Kulesi simo, kwasungulwa imishini yokwelapha amanzi amdaka ehlanganisiwe ye-PPH. Yamukela indlela yokwelapha ngebhayoloji, ihlanganisa ukwelashwa nge-aerobic, ukwelashwa nge-anaerobic kanye nezinye izindlela zokwelapha, ngokusebenza kahle kakhulu kokwelapha, izindleko zokusebenza eziphansi, njll. Ukuvela kwemishini yokwelapha amanzi amdaka ehlanganisiwe ye-PPH kukhuthaza kakhulu intuthuko yobuchwepheshe bokwelapha amanzi amdaka, futhi iba yisisombululo sokwelapha amanzi amdaka esisebenza kahle nesinobungani nemvelo.
Ngentuthuko eqhubekayo yobuchwepheshe kanye nezidingo zokuvikela imvelo, imishini yokwelapha amanzi amdaka ehlanganisiwe ye-PPH nayo ithuthuka futhi ishintsha njalo. Imishini yokuqala yayiwukwelapha okulula indle evela emakhaya, emiphakathini emincane nasezindaweni zezentengiselwano. Ngokukhula okuqhubekayo kobukhulu bedolobha kanye nentuthuko esheshayo yezimboni, isidingo sokwelashwa kwendle siyakhula, futhi ubukhulu kanye nokusebenza kwemishini yokwelapha indle ehlanganisiwe ye-PPH nakho kuthuthukiswa njalo.
Inqubo yokwelapha ngebhayoloji yemishini yokwelapha amanzi amdaka ehlanganisiwe ye-PPH isebenza kahle kakhulu, engasusa ngempumelelo izinto eziphilayo, i-nitrogen, i-phosphorus kanye nezinye izinto ezingcolisayo emanzini angcolile ukuze kufezwe izinkomba ezinhle zekhwalithi yamanzi. Le mishini inesakhiwo esincane kanye nendawo encane, efanele ukusetshenziswa ezindaweni ezinesikhala esincane. I-PPH ihlanganisiweimishini yokwelapha amanzi amdakaivame ukuhlonyiswa ngohlelo lokulawula oluzenzakalelayo, oluvumela ukuqapha nokulungisa kude futhi lunciphise izindleko zokusebenza ngesandla. Imishini isebenzisa ubuchwepheshe bokungenisa umoya obusebenza kahle kakhulu ukuze inciphise ukusetshenziswa kwamandla; ngesikhathi esifanayo, ukwakheka kwayo okuhle kwesakhiwo kusiza ukunciphisa izindleko zokusebenza. Inqubo yokwelapha ngezinto eziphilayo inobungani nemvelo futhi inciphisa umthelela omubi ohlelweni lwemvelo.
Kubalulekile ukukhetha imishini yokwelapha amanzi amdaka ehlanganisiwe ye-PPH, ubuchwepheshe bokuthuthukiswa komkhiqizo kanye nolwazi lokusebenza kwephrojekthi, ngokuvamile, kufanele ukhethe imikhiqizo engaqhubeka nokuma imakethe, lapha ukuncoma imishini ye-PPH ekhiqizwe yi-Liding Environmental Protection Company, engenziwa ngokwezifiso ngokuya ngesidingo semakethe sohlobo lomkhiqizo olufanele.
