I-Polyaluminium chloride isetyenziswa ehlotyeni
Njengoko kufika ihlobo, ubushushu buya busanda, ngenxa yokunyuka kobushushu basehlotyeni, ukukhawuleziswa kokuzivocavoca kweemolekyuli, nokuba yinkunkuma yasekhaya okanye inkunkuma yemizi-mveliso xa unyango lungekho ngexesha kuya kuvela ivumba elimnyama, ngoko ke ihlobo likwalixesha lokusetyenziswa kweemveliso zokucoca amanzi, ngoko ke, kweli xesha lishushu ukusebenzisa i-polyaluminum chloride kufuneka unikele ingqalelo kwinto, yintoni ifuthe lobushushu obuphezulu kwi-polyaluminium chloride?
Ngokwesakhiwo semolekyuli se-polyaluminum chloride, i-PAC ifunyenwe iyi-molecule mass esebenzayo. Xa ubushushu butshintsha, ulwakhiwo lwayo lwangaphakathi luyatshintsha. Esi sakhiwo semolekyuli sizinzile phakathi kwama-degrees ama-5 nama-degrees angama-20. Ubushushu ehlotyeni buphezulu kakhulu kune-degrees ezingama-20, xa ubushushu buphezulu, izinga lokunyibilika kunye nezinga lokusabela kwe-polyaluminum chloride liya kukhawuleziswa, ngoko ke ixesha lokunyibilika kunye nexesha lokusabela linokulungiswa ngokufanelekileyo. Ingakumbi kwimeko yangaphandle, ukufuma kunye nemvula kuya kukhokelela kutshintsho kuxinzelelo lwe-polyaluminum chloride kunye nomgangatho wokungcola, ngeli xesha, kuyimfuneko ukwenza olunye uvavanyo oluncinci ukulinganisa ukusetyenziswa okufanelekileyo kwe-polyaluminum chloride. Ehlotyeni, amanzi okucoca ukongeza i-polyaluminum chloride, aya kwenza intyatyambo enkulu exineneyo, isiphumo sokucoca amanzi sicacile. Xa idosi incinci, impendulo ye-polyaluminum chloride isenokukhawuleza kubushushu obuphezulu.
Ngamafutshane, kukho iinkalo ezininzi ekufuneka ziqatshelwe ekusebenziseni iimveliso zokucoca amanzi ze-polyaluminum chloride ehlotyeni. Nangona kunjalo, amaqondo obushushu aphezulu ehlotyeni awazange ayichaphazele impembelelo ye-flocculation ye-polyaluminum chloride.
