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. As compared to conventional methods, advantages of certain embodiments include one or more of: higher efficiencies, higher capacities, higher integrity against more aggressive feeds and higher temperatures, increased impurity recyclability, increased product quality, increased automation, increased simplicity, reduced waste, high modularization allowing enhanced scale-up, and lower operational and capital costs.
