Abstract
A method of removing suspended solids from a gasification process water stream includes, in an exemplary embodiment, providing a gasification process water stream containing process derived suspended solids, settling at least a portion of the suspended solids from the process water stream in a settling apparatus, providing a filter apparatus having a plurality of filter elements, and removing a portion of the settled solids from the settling apparatus. The method also includes precoating the filter elements with the settled solids removed from the settling apparatus, directing a portion of the process water stream from the settling apparatus to the filter apparatus, and filtering the portion of the process water stream directed from the settling apparatus through the precoated filter elements to remove suspended solids particles to form a filtrate.
