Ndekọ mma nke PAC (polyaluminum chloride)
Kedu ihe ngosi atọ kachasị mkpa nke PAC (polyaluminum chloride)? Salinity, uru PH, na ọdịnaya alumina nke na-ekpebi ịdị mma nke polyaluminum chloride bụ ihe ngosi atọ kachasị mkpa nke polyaluminom chloride.
1. Salinity.
A na-akpọ ogo hydroxylation ma ọ bụ alkalization nke ụdị ụfọdụ na PAC (polyaluminum chloride) ogo nke isi ma ọ bụ alkalinity. A na-egosipụtakarị ya site na nha molar nke aluminom hydroxide B=[OH]/[Al] pasent. Salinity bụ otu n'ime ihe ngosi kachasị mkpa nke polyaluminum chloride, nke nwere njikọ chiri anya na mmetụta flocculation. Ihe dị elu na ntinye mmiri raw na nke dị elu nke salinity, otú ahụ ka mmetụta flocculation dịkwuo mma. Iji chịkọta, na nso nke raw mmiri turbidity nke 86 ~ 10000mg / L, kacha salinity nke polyaluminum chloride bụ 409 ~ 853, na ọtụtụ ndị ọzọ e ji mara nke polyaluminom chloride metụtara salinity.
2. pH uru.
