Abstract:
Provided is a bead in which an adsorbent and an organic contaminant-degrading microorganism are supported, wherein an adsorbent for adsorbing organic contaminants is supported on the bead together with an organic contaminant-degrading microorganism for degrading the organic contaminants adsorbed to the adsorbent to allow for the adsorbent to remove organic contaminants in water and to allow for the organic contaminant-degrading microorganism to regenerate the adsorbent.
Abstract:
Disclosed is an apparatus and method for recovery of target gas, which may increase a target gas concentration in a recovered gas by using a single gas separation membrane module and a plurality of gas storage tanks. The apparatus for recovery of target gas includes a gas separation membrane module configured to perform an enrichment process n times (n is a natural number) so that an injected gas is separated into a permeated gas and a recovered gas in each enrichment process, and (n+1) number of gas storage tanks, wherein in an nth enrichment process, gas stored in an nth gas storage tank is supplied to the gas separation membrane module and separated into an nth permeated gas and an nth recovered gas, the nth permeated gas is stored in a (n−1)th gas storage tank, and the nth recovered gas is stored in a (n+1)th gas storage tank.

Abstract:
The present disclosure provides a gas separation membrane using a ladder-structured polysilsesquioxane in which organic functional groups are attached to a long siloxane chain and a method for fabricating the same. In accordance with the present disclosure, a free-standing ladder-structured polysilsesquioxane-based membrane with various functional groups can be fabricated for gas separations. The performance of the gas separation membrane can be controlled through a variety of combinations of the organic functional groups linked to the siloxane chain. In addition, by controlling the molecular structure of the gas separation membrane through mixing of the ladder-structured polysilsesquioxane with an amine compound or conventional glassy or rubbery polymers or through thermal/UV-curing, the permeability and selectivity of the gas separation membrane can be controlled selectively.
Abstract:
The apparatus for water treatment using in-situ activation of a manganese dioxide catalyst includes: a reaction bath configured to give a space where aqueous organic contaminants are removed by means of reaction with permanganate (MnO4−) generated by electrochemical oxidation of manganese oxide (MnO2); a plurality of manganese dioxide catalysts provided at the reaction bath and electrochemically oxidized into permanganate (MnO4−) by a voltage applied thereto; and a power supply device configured to apply power to the manganese dioxide catalyst so that the manganese dioxide (MnO2) is electrochemically oxidized into permanganate (MnO4−).
