Kukweza ndi njira yomwe imayimbidwa mlandu womwe umayimitsidwa tinthu tayimitsidwa m'madzi okhazikika m'madzi amapezeka. Izi zimatheka powonjezera chidwi chokwanira. Kulipiritsa koyenera mu coagulant kumayambitsa vuto lililonse pamadzi (mwachitsanzo, adani). Tikakhala zokhazikika kapena zosagawanika, njira yodzipangira imachitika. Tinthu tating'onoting'ono timaphatikizanso tinthu tating'onoting'ono komanso tinthu tating'onoting'ono mpaka atakhala olemera kuti tikhazikike ndi ma shetmentation kapena kupitirira zokwanira msampha ndi thovu la mpweya ndikuyandama.
Lero tionana bwino kwambiri za maluwa awiri ofala: Poly aluminiyam chloride ndi aluminium sulfate.
Aluminium sulfate: Aluminium sulfate ndi acidic mwachilengedwe. Mfundo yogwira ntchito ya aluminium sulfate ndi motere: aluminium sulfate imatulutsa aluminium hydroxide, al (0h) 3. Aluminium hydroxides ali ndi magawo ocheperako, pamwambapa omwe sadzagwiritsa ntchito phomphon . Achimwemwe m'madzi ayenera kukhala okwanira nthawi yopuma kuti awonetsetse kuti hydroxide yopangidwa kwathunthu ndi yopangidwa. Amachotsa mitundu ndi colloidial zida kudzera mu kuphatikiza kwa ADSORORARD ndi Hydrolysis pa / mu heldroxides. Chifukwa chake, Phwi la PH la Aluminium sulfate ndilokhali mosamalitsa 5.8-8.5, kotero ndikofunikira kuti muwonetsetse ph zowongolera bwino pogwiritsa ntchito aluminium sulfate.
Polyoluminim chloride(Pac) ndi imodzi mwazomwezi zimagwiritsidwa ntchito mankhwala masiku ano. Amagwiritsidwa ntchito kwambiri pakumwa madzi ndi chithandizo chamadzi chifukwa cha mphamvu zambiri komanso njira zazitali za PH ndi kutentha poyerekeza ndi mankhwala ena othandizira madzi. Pac imapezeka m'makalasi osiyanasiyana osiyanasiyana okhala ndi alumina njira yochokera ku 28% mpaka 30%. Alumina kukhazikika si lingaliro lokhalo posankha kalasi ya pac.
Pac imatha kuonedwa ngati pre-hydrolysis pre-hydrolysis pre-hydrolysis. Masamba a aluminisis aluminisis aluminisis ali ndi vuto lalikulu kwambiri, zomwe zimapangitsa pac yambiri kuposa alum.
Pac ili ndi maubwino otsatirawa a aluminium sulfate
1. Imagwira ntchito mosiyanasiyana. Monga lamulo la chala, Mlingo wa pac ndi pafupifupi gawo limodzi mwa magawo atatu a mlingo wofunikira a Alum.
2. Imasiya yotsalira yotsalira mu madzi osungidwa
3. Imabweretsa sludge pang'ono
4. Imagwira ntchito mosiyanasiyana
Pali mitundu yambiri ya oyendetsedwa, ndipo nkhaniyi ingolowetsa awiri a iwo. Mukamasankha coaglant, muyenera kuganizira mtundu womwe mukuchiritsa komanso bajeti yanu. Ndikukhulupirira kuti muli ndi chithandizo chamadzi abwino. Monga mankhwala othandizira mankhwala othandizirana ndi zaka 28 za zokumana nazo. Ndili wokondwa kuthetsa mavuto anu onse (pafupifupi mankhwala othandizira madzi).
