I-Scheccucation-I-Aluminium sulphate vs poly aluminim chloride

I-Scheccucation yinkqubo apho kuhlawuliswa kakubi amasuntswana anqunyanyisiweyo ngokumiselweyo ekunqunyanyisweni kwamanzi achaphazeleka. Oku kufezekiswa ngokongeza i-reagulnt ye-reagult. Ityala elifanelekileyo kwi-COUGLARE lingathathi cala indleko ezingekhoyo emanzini (oktselisa). Nje ukuba amasuntswana achithe okanye ahlanjululwe, inkqubo yokuhlaselwa yenzekile. Amasuntswana amiselweyo adibanisa abe ngamasuntswana amakhulu kwaye amakhulu ade ade axabiseke ngokwaneleyo ukuba angazinza nge-sediment okanye amakhulu ngokwaneleyo ukuba adibanise iibhubhu zomoya kunye ne-float.

Namhlanje siza kujonga ngokusondeleyo kwiipropathi zokubhalwa kweSycckings ezimbini eziqhelekileyo: I-Poly Aluminium Chloride kunye ne-aluminium Sulfate.

I-Aluminium Sulfate: I-Alweminium ye-acidic kwindalo. Umgaqo wokuSebenza we-AlUminium I-Alulfate ilandelayo: I-Aluminium Sulfate ivelisa i-Aluminium hydroxide, al (0h) 3. I-Aluminium Hydroxides inoluhlu lwe-HL, ngaphezulu kwe-hydrolylussis okanye, i-Hydrophelom Hydroxides ihlawulwe ngokukhawuleza kwi-2 ka-PH (i-PH kufuneka ilawulwe ngenyameko ukuyigcina kuluhlu lwe-5.8-8.5. I-alkalinity emanzini kufuneka yanele ngexesha lenkqubo yokubhalwa ukuze iqinisekise ukuba i-hydroxide ye-inkcings isenziwa ngokupheleleyo kwaye icacisiwe. Isusa imibala kunye nezinto zeColoidal ngokudityaniswa kwe-adsorlys kunye ne-hydrolysis kwi / kwi-thydroxides. Ke ngoko, i-prindo yokusebenza ye-aluminium i-allisum i-5.8-8.5, ke kubaluleke kakhulu ukuqinisekisa ulawulo olululo lwenkqubo xa usebenzisa i-aluminium ye-allinum.

I-polloluminum chloride(I-PAC) yenye yezona zikhemikhali zisebenzayo zonyango ezisetyenzisiweyo namhlanje. Kusetyenziswa ngokubanzi ekulweni amanzi kunye nonyango lwamanzi amdaka ngenxa yokusebenza kwayo impumelelo kunye nenqanaba eliphezulu le-PH kunye nezicelo zeqondo lobushushu ezithelekiswa nezinye iikhemikhali zonyango lwamanzi. I-PAC iyafumaneka kumabakala aliqela ahlukeneyo nge-Aluminii United ukusuka kwi-28% ukuya kwi-30%. I-Aluminii Union ayikuphela kokuqwalaselwa xa ukhetha icandelo le-PAC ukuba lisebenzise.

I-PAC inokuthathwa njenge-hydrolysis quigulant. Iqela langaphambi kwe-i-hydrolysis line-chancers ende kakhulu, eyenza i-pac engaphezulu kwe-cumic ngaphezulu kwe-alum. ikhulisa i-ALM.UKHUNYIWEYO YENZA UMSEBENZI OWENZELAYO NGOKUGQIBELA NGOKUGQIBELA.

I-PAC inezibonelelo ezilandelayo kwi-aluminium Sulfate

1. Isebenza kwiindawo eziphantsi kakhulu. Njengomthetho wesithupha, idosi ye-PAC imalunga nesinye kwisithathu sedosi efunekayo kwi-Alum.

2. Ishiya i-aluminium engaphantsi ye-aluminium kumanzi athambileyo

I-3. Ivelisa i-sludge encinci

I-4. Isebenza ngaphezulu kwe-PH ye-PH

Zininzi iindidi zeeflounts, kwaye eli nqaku lazisa kuphela ezimbini zazo. Xa ukhetha i-cougulant, kuya kufuneka uqwalasele umgangatho wamanzi owuphathayo kunye nohlahlo-lwabiwo mali lwakho. Ndiyathemba ukuba unamava amahle onyango oluhle. Njengomthengisi wonyango lwamachiza aneminyaka engama-28 yamava. Ndonwabile ukusombulula zonke iingxaki zakho (malunga neekhemikhali zonyango).
