Abstract: Methods and systems for enhanced water treatment comprise inorganic filter systems for impurity removal. Embodiments for water impurity removal include introducing contaminated water into an impurity removal system having an inorganic filter. The inorganic filter comprises an inorganic membrane layer supported by an inorganic support. The inorganic membrane layer comprises pores sized from about 1,000 Daltons to about 10 microns for filtering impurities such as kinetic hydrate inhibitor. Other pre-treatment and post-treatment stages may be included. The inorganic membrane layer or inorganic membrane support may comprise a ceramic such as alumina, zirconia, silica, silicon carbide, and mixed oxides.

Abstract: A process for removing selenium from an aqueous stream using a supported sulfur material, and optionally the addition of an activating agent for enhanced removal of selenite, is disclosed.

Abstract: A biofilter composition of leonardite, clay, lime, and an inorganic salt mixture and a process for controlling air quality by contacting an air stream with the biofilter composition are provided wherein the composition supports microbial growth. The inorganic salt mixture comprises a nitrogen source and a phosphorus source. The air stream generally contains at least one volatile organic compound.
