Provided are catalytic assemblies which include a hollow fiber membrane permeable to a gas; a reactive coating permeable to the gas and a contaminant; and a plurality of catalytic nanoparticles embedded in the reactive coating adapted to catalyze a reaction between the gas and the contaminant. Also provided are preparation methods for the catalytic assemblies, and use thereof for treating contaminated water.

Catalytic hydrogel membrane reactor for treatment of aqueous contaminants

An apparatus and method for treatment of water borne oxidized contaminants, using hydrogen as an electron donor for denitrification and reduction of other oxidized contaminants. Preliminary results reported here show that a biofilm of autotrophic denitrifiers accumulates rapidly in the wastewater setting, the MBfR can drive NOconcentrations below 1 mgN/L, and the Hpressure controls the NOflux.

Apparatus and methods for water treatment

Apparatus for water treatment

Removal of oxidized contaminants from water. Perchlorate and other oxidized contaminants are reduced and removed from water with a method using a primary electron acceptor.
