Ndepụta àgwà nke PAC (polyaluminum chloride)
Kedu ihe atọ kacha mkpa na-egosi àgwà PAC (polyaluminum chloride)? Nnu, uru PH, na ọdịnaya alumina nke na-ekpebi ịdị mma nke polyaluminum chloride bụ ihe ngosi atọ kachasị mkpa nke polyaluminum chloride.
1. Nnu dị n'ime.
A na-akpọ ogo hydroxylation ma ọ bụ alkalization nke ụdị ụfọdụ na PAC (polyaluminum chloride) ogo nke basicity ma ọ bụ alkalinity. A na-egosipụta ya site na oke molar nke aluminum hydroxide B=[OH]/[Al] pasentị. Nnu bụ otu n'ime ihe ngosi kachasị mkpa nke polyaluminum chloride, nke nwere njikọ chiri anya na mmetụta flocculation.
