Abstract
Processes and apparatus for the removal of waste metabolites from metabolite-containing solutions are disclosed. The disclosed processes include alternatively adsorbing and desorbing the metabolites on a pair of adsorbent-containing columns, each column being maintained at a reduced temperature during adsorption and at an elevated temperature during desorption, with the columns being flushed subsequent to desorption and prior to their re-use for adsorption thereon. The disclosed apparatus includes a pair of adsorbent-containing columns, means for alternatively delivering the metabolite containing solution to each of the columns for alternate adsorption and desorption thereon, means for withdrawing the metabolite containing solution from each of the columns, means for alternately flushing the columns subsequent to desorption and prior to adsorption thereon, and means for alternately maintaining the columns at reduced temperatures during adsorption and at elevated temperatures during desorption so that the effectiveness of the adsorbent for adsorption is increased during adsorption at the reduced temperatures. A disposable tube set for use in connection with such a pair of adsorbent …
