Xa ujongaUnyango lwamanzi amdakaInkqubo, qala ngokumisela into ekufuneka uyisuse emanzini ukuze udibane neemfuno zokukhutshwa. Ngonyango olufanelekileyo lweekhemikhali, ungasusa i-ion kunye nezinyibilikisi ezincinci ezivela emanzini, kunye nezinyibilikisi ezinqunyanyisiweyo. Iichemicals ezisetyenziswa kwizityalo zonyango lwe-sebage ikakhulu zibandakanya: I-PH yoMlawuli, i-Coulant,iflocculant.
Iflocculant
I-Dlocculctions isetyenziswa kuluhlu olubanzi lwamashishini kunye nokusetyenziswa ukunceda ukususa iinyibilikisi ukusuka kumanzi amdaka ngokuhlasela amashiti okanye "flocs" ezithambekele ezantsi. Banokusetyenziselwa ukuthamba i-lime, i-sludre jollucrec kunye nehlelo lokulimala. Iipesenti zendalo okanye eziqholiweyo zibandakanya i-silica esebenzayo kunye ne-Polysaccharides, ngelixa i-synthetic syctions iqhelekileI-Polyacrylamlasside.
Kuxhomekeka kwi-ntlawulo kunye nokwenziwa kwamachiza amanzi amdaka, amafutha anokusetyenziswa bodwa okanye ngokudibeneyo kunye ne-Coaglants.I-Dlocccuys zahlukile kwii-coglantskuba badla ngokuthi ze-polymers, ngelixa i-dagullants ihlala ityiwa. Ubungakanani babo molecular (ubunzima) kunye nokuxinana kweemolekyuli (ipesenti yeemolekyuli ze-aneion okanye intlawulo) ye "Balance" intlawulo yamasuntswana emanzini kwaye ibangele ukuba badibane kunye nehydisiweyo. Ngokubanzi, i-anaion isetyenziselwa ukuhambisa amasuntswana amaneral, ngelixa i-caicic cloccuys isetyenziselwa ukuqhuba amasuntswana endalo.
PH umlawuli
Ukususa iintsimbi kunye nezinye izinto ezingcolisekileyo ezivela kumanzi amdaka, uMlawuli we-PH unokusetyenziswa. Ngokukhulisa i-PH yamanzi, kwaye ngaloo ndlela ikhulisa inani lee-hydroxide ezimbi, oku kuya kubangela i-ion yentsimbi ebizelwe ukuba iboshwe zii-hydroxide ezihlawulelwayo. Oku kubangela ukucocwa kwamasuntswana angenamntu.
I-cogalant
Kuyo nayiphi na inkqubo yonyango lwamanzi athatyathwayo enqunyanyisiweyo, i-Coaglants ingadibanisa ungcoliseko olunqunyanyisiweyo lokususwa ngokulula. I-Comicallagnts Oogshants esetyenziselwa ukuqhubeka kwamanzi amdaka omzi-mveliso wahlulahlulwe lwaba lindidi ezimbini: i-organic kunye nenorganic.
I-Inorganic Deaglants isebenza ngexabiso kwaye inokusetyenziselwa uluhlu olubanzi lwezicelo. Basebenza ngokukodwa kumanzi aluhlaza athile Xa kudityanisiwe kumanzi, i-Inorganic Coaglants evela kwi-Aluminiyam okanye intsimbi ichaza i-iron okanye i-iron ityhutyha amanzi emanzini kwaye icoce. Oku kwaziwa ngokuba "yi-sweep-kunye ne-flocclesm". Ngelixa isebenza, inkqubo yonyusa inani lilonke le-sludge ekufuneka isuswe emanzini. I-corgann eqhelekileyo ye-inorganic iqokelela i-aluminium sulfate, ialuminium chloride, kunye ne-ferric calfate.
Imibutho ye-organic ineengenelo zomthamo ophantsi, imveliso encinci ye-Sludge kwaye akukho mpembelelo kwi-PH yamanzi athambileyo. Imizekelo ye-collegines eqhelekileyo ibandakanya i-Polyamines kunye nePolydimethy Dolium Hloride, kunye neMelamine, i-follemine, i-formaldehyde kunye neTannins.
Umgca wethu weefreyimu kunye neemeglants zenzelwe ukuphucula unyango lwamanzi amdaka kwaye unciphise iindleko zosetyenziso lwemizi, ukuhlangabezana nemfuno yeendlela zokunyanga eziphindaphindiweyo.
