The use of anion‐exchange resins for removal of acids from potato starch factory waste‐water (after prior removal of proteins and amino acids) was studied. Over 99% of the acids were removed by the process. Data are given on the effect of influent temperature and flow‐rate on column efficiency during the acid adsorption step. Data are also given on methods of increasing the concentration of acids in the eluate by increasing the alkalinity of the eluting agent or by recycling the eluate. Possible uses for the eluate are discussed.
