REMOVAL OF NONSPECIFIC DISSOLVED ORGANIC-MATTER FROM UPLAND POTABLE WATER-SUPPLIES .1. ADSORPTION

The presence of a dissolved organic component in potable water supplie s is not only aesthetically undesirable, frequently imparting colour, tastes and odours to treated waters, but may also be associated with a variety of quality problems potentially hazardous to health. The remo val of organic compounds is therefore imperative, and may be effected by adsorption onto activated carbon or a range of other porous solids. This paper investigates the amenability of non-specific natural organ ic compounds for removal by adsorption onto activated carbon, activate d alumina, activated bauxite and bone char adsorbents.
