Reduction of Perchlorate and Other Micropollutants in a Hydrogen- Based, Hollow-Fiber Membrane Biofilm Reactor
نویسنده
چکیده
The membrane biofilm reactor (MBfR) a novel bioreactor that provides gaseous substrates directly to a biofilm growing on the membrane surface, avoiding the need for sparging. MBfRs are not membrane bioreactors (MBRs), where membranes separate suspended solids from the effluent water, substituting for a clarifier. In MBfRs, a gaseous substrate moves across the membrane. Since the MBfR membranes typically are microporous and hydrophobic, water and bacteria do not penetrate and block the pores. This paper describes H2-based MBfRs for removal of perchlorate and other oxidized micropollutants contaminants.

Hydrogen-based, hollow-fiber membrane biofilm reactor for reduction of perchlorate and other oxidized contaminants.
Many oxidized pollutants, such as nitrate, perchlorate, bromate, and chlorinated solvents, can be microbially reduced to less toxic or less soluble forms. For drinking water treatment, an electron donor must be added. Hydrogen is an ideal electron donor, as it is non-toxic, inexpensive, and sparsely soluble. We tested a hydrogen-based, hollow-fiber membrane biofilm reactor (MBfR) for reduction ...
متن کاملNew Polymer Catalytic Membranes for Nitrite Reduction: Experimental Assessment
In this work we report the experimental assessment of the performance of a new catalytic hollow fiber reactor with supported Pd catalyst for nitrite removal from polluted waters. The reactor configuration facilitates working at low flowrate and hydrogen concentrations in order to improve the selectivity of the reduction reaction towards nitrogen, thus, inhibiting the formation of ammonia. Pd ca...
متن کاملMultidimensional modeling of biofilm development and fluid dynamics in a hydrogen-based, membrane biofilm reactor (MBfR).
A two-dimensional, particle-based biofilm model coupled with mass transport and computational fluid dynamics was developed to simulate autotrophic denitrification in a spiral-wound membrane biofilm reactor (MBfR), where hydrogen is supplied via hollow-fiber membrane fabric. The spiral-wound configuration consists of alternating layers of plastic spacer net and membrane fabric that create rows o...
متن کاملTotal Nitrogen Removal in a Completely Mixed Membrane Biofilm Reactor for Nitrification and Denitrification
A Hollow-fiber Membrane Biofilm Reactor (MBfR) was used to nitrify and denitrify synthetic wastewater to remove nitrogenous pollutants such as ammonium, nitrate, and nitrite. Aerobic and anoxic MBfRs were combined to oxidize and reduce these nitrogenous pollutions using biofilms as the catalyst for these chemical reactions. The MBfR is capable of converting ammonium (NH4) to nitrogen gas (N2), ...
متن کاملPossibility of the Use of Hollow Fiber Membrane Contactors for Phenol Biodegradation in Saline Solutions
A microporous polypropylene (PP) hollow fiber membrane contactor was used as a reactor to biodegrade phenol in high-salinity solutions by Pseudomonas putida CCRC14365 at 30C. Suspended cells grew only at a NaCl concentration below 2.5 wt%. On the other hand, cells within hollow fibers completely degraded 0.5 g/L of phenol in solution containing NaCl up to 8.6 wt%, likely due to the fact that th...
