ABSTRACT:
A method and apparatus for conducting the method is provided for separating suspended solids such as, nickel, chromium, zinc, copper, iron, etc., from a liquid containing such solids. The method comprises contacting such a liquid containing suspended solids with a liquid-absorbing medium. The liquid-absorbing medium selectively absorbs the liquid to the substantial exclusion of absorbing the suspended solids. After some liquid is absorbed, absorbed liquid is removed from the medium to refresh the medium and allow for the absorption of additional liquid concomitantly with the removal of liquid. The liquid removed from the liquid-absorbing medium is effectively separated from the solids. The apparatus comprises a solids-liquid separation unit which includes a perforated base having a dish-shaped upper portion. A liquid-absorbing medium is placed across the top of the base to form a seal over the perforations therein. A liquid-receiving chamber is provided below the perforated base. A means for removing absorbed liquid from the liquid-absorbing medium is provided within the liquid-receiving chamber. A drying unit can also be provided, and the liquid-absorbing medium can be moved from the solids-liquid separtion unit to the drying unit for drying the medium and for permitting the solids to be removed from the liquid-absorbing medium.
