Xa Uqwalasela YakhoUkucocwa kwamanzi amdakaInkqubo, Qala ngokumisela into okufuneka uyisuse emanzini ukuze uhlangabezane neemfuno zokukhutshwa. NgoNyango oluLungileyo lweMichiza, unokukhupha ii-Ions kunye nezinto ezincinci ezinyibilikileyo emanzini, kunye neZiqina ezimisiweyo. Imichiza eSetyenziswa kwiziko lokucocwa kogutyulo ikakhulu iquka:I-Flocculant, Ph Regulator, Coagulant.
I-Flocculant
IiFlocculants zisetyenziswa kuluhlu olubanzi lwamashishini kunye neziceloUkuNceda Ukukhupha Izinto Eziqinileyo Ezinqunyanyiswayo Kumanzi Amdaka Ngokugqalisela Izinto Ezingcolisayo KuMashidi Okanye “iiFlokhwe” ezidada phezu komphezulu okanye zihlale emazantsi. Zinokusetyenziselwa ukuthambisa ikalika, ukugxila kwi-Sludge kunye ne-Dehydrate Solids. IiFlocculants zeNdalo okanye zeMineral ziquka iSilica eSebenzayo kunye neePolysaccharides, ngelixa iiFlocculants zeSynthetic zihlala ziPolyacrylamide.
Ngokuxhomekeke kuMrhumo kunye noBume beMichiza bamanzi amdaka, iiFlocculants zinokusetyenziswa zodwa okanye ngokudityaniswa neCoagulants. IiFlocculants zahlukile kwiiCoagulants kuba zihlala ziziPolymers, ngelixa iiCoagulants ziqhele ukuba ziityuwa. Ubungakanani babo beMolekyuli (Ubunzima) kunye nokuxinwa kweCharge (Ipesenti yeeMolekyuli ezineAnionic okanye iCationic Charges) zinokuhluka "Ukulinganisa" ukuhlawuliswa kwamasuntswana emanzini kwaye kubangele ukuba bahlangane kunye kwaye bangabi namanzi. Ngokuqhelekileyo, iiFlocculants ze-Anionic zisetyenziselwa ukukhwela i-Mineral Particles, ngelixa i-Cationic Flocculants isetyenziselwa ukukhwela i-Organic Particles.
PH Umlawuli
Ukususa isinyithi kunye nezinye izingcolisi ezinyibilikisiweyo kumanzi amdaka, umlawuli we-pH unokusetyenziswa. Ngokunyusa i-pH yamanzi, kwaye ngaloo ndlela ukwandisa inani le-oni ye-hydroxide engalunganga, oku kuya kubangela ukuba ii-ion zetsimbi ezihlawulweyo zibophene nezi ionni zehydroxide ezichajiwe kakubi. Oku kubangela ukuhluzwa kweentsimbi ezixineneyo nezinganyibilikiyo.
I-Coagulant
Kuyo nayiphi na inkqubo yokucoca amanzi amdaka eNyanga iZiqina eziNxinyiweyo, iiCoagulants zinokudibanisa izingcolisi ezimisiweyo ukuze zisuswe ngokulula. Ii-Coagulants zeMichiza eziSetyenziselwa ukucocwa kwaManzi amdaka akwimizi-mveliso zahlulwe zaba lunye lwezintlu ezimbini: i-Organic kunye ne-Inorganic.
Ii-Inorganic Coagulants zineendleko-Ngezisebenzayo kwaye zinokusetyenziselwa uluhlu olubanzi lwezicelo. Zisebenza Ngokukodwa ngokuchasene namanzi akrwada kuyo nayiphi na i-turbidity ephantsi, kwaye esi sicelo asifanelekanga kwi-Organic Coagulants. Xa iFakelwa kuManzi, i-Inorganic Coagulants esuka kwiAluminiyam okanye i-Iron Precipitate, ifunxa ubumdaka emanzini kwaye iwacokise. Oku Kwaziwa njengeNdlela yokuTshayela-kunye-Flocculate. Ngelixa iSebenzayo, Inkqubo Yonyusa Isixa Sisonke se-Sludge esifuna ukuKhutshwa kuManzi. I-Coagulants ye-Inorganic Coagulants eqhelekileyo iquka i-Aluminium Sulfate, i-Aluminiyam Chloride, kunye ne-Ferric Sulfate.
I-Organic Coagulants ine-Advantages yomthamo ophantsi, iMveliso ye-Sludge encinci kwaye akukho siphumo kwi-Ph yamanzi acociweyo. Imizekelo yee-Common Organic Coagulants ibandakanya iiPolyamines kunye nePolydimethyl Diallyl Ammonium Chloride, kunye neMelamine, iFormaldehyde kunye neTannins.
