Abstract
A pump and valve arrangement (), a dialysis system () comprising the pump and valve arrangementand a method of operating a pump and valve arrangement (). The pump and valve arrangement () has a dialyser having a semi-permeable membrane. The pump and valve arrangement () delivers dialysis fluid to and from the dialyser (). The pump and valve arrangement () has a control system () configured to shuttle dialysis fluid between an inlet pump assembly and the dialyser () one or more times so as to agitate the surface of the semi-permeable membrane of the dialyser ().
