Abstract
Apparatus for the treatment of dialysate for the hemodialyzer in which apparatus the dialysate is recirculated and urea and other toxins in the dialysate are removed by repeated adsorption on and desorption from an adsorbent packed in a plurality of adsorbent beds that are used alternately or in rotation. Valves controlling flows of recirculating dialysate and the liquid (water and fresh dialysate) for desorption to and from said adsorbent beds are operated automatically with use of a timing device.
