SMEBR
Submerged Membrane Electro-Bioreactor, or SMEBR, is a very competitive and compact hybrid unit in one reactor
when compared to conventional membrane systems that biological process, membrane filtration and electro-kinetic
phenomena are carried out for wastewater treatment, controlling membrane fouling and the removal of nutrients.
· The SMEBR system is based on applying an intermittent direct current (DC) field between
immersed circular perforated electrodes around a membrane filtration module.
· A novel Submerged Membrane Electro-Bioreactor (SMEBR) is developed to significantly
reduce the fouling rate when iron worked as electrodes and an intermittent DC with several operational modes.
· Application of the SMEBR system enhanced the membrane filterability
by reducing the fouling rate up to min. 15% without any backwashing of the membrane module.
· In the SMEBR system, relationship between different levels of current density
and electrode configuration played an important role for nutrient removal.
· The SMEBR system could accomplish almost complete nitrification of ammonium and de-nitrification of nitrate.
· Phosphorous could be removed by the formation of aluminum phosphate.
· COD can be removed through oxidation of biomass and microbial activities in the electro-bioreactor.
