The biological degradation of selenate to elemental selenium and recovery of valuable selenium nanoparticles has been extensively studied
and reported by researchers throughout literature. The major challenges in degradation and recovery processes are the reduction of high
concentration of selenium oxyanions and effective separation of bacterial cells and sludge from these economically beneficial elemental selenium
nanoparticles. This study seeks to investigate the efficacy of a novel combination system comprising a biological reactor, a separating chamber
and a tangential-flow ultrafiltration module (TFU). The biological reactor was investigated for its ability to reduce selenate at high loading
rates. The separating chamber containing the inclined bacterium-nanoparticle separator was investigated for its ability to separate bacteria
from nanoparticles. The TFU was investigated for its ability to induce a water-bacterium-nanoparticles separation even at high selenate loading
rates. The reactor system worked in synergism to remove high concentration of selenate from wastewater and simultaneously recover the valuable
elemental selenium nanoparticles thereby eliminating the additional use of chemicals or post-treatment operations. / A Thesis submitted to the Department of Civil and Environmental Engineering in partial fulfillment of the
