A direct contact membrane distillation(DCMD)process was applied to prepare high concentration polyaluminum chloride(PACl)with high Al

content.The changes in total Al concentration(Al

)and Al species distribution were investigated.The results showed that Al

increased but the flux decreased with operating time during the DCMD process.The Al

content increased from 65%to 81% while the Al

content decreased from 34% to 18%

and the Al

content was almost 1%in the process.2.1 mol·L

-1

PACl with 81%Al

was successfully prepared by DCMD method.Thus the DCMD is an effective method for preparing high concentration PACl with high Al

content.
