Using the Membrane Biofilm Reactor (MBfR) to Recover Platinum Group Metals (PGM), Rare Earth Elements (REE), and Valuable materials as Nanoparticles from Wastewater

Lusk B.G., Calvo D., Ray C., Zhou C., Rittmann B.E., Precient Technologies, US

Platinum group metal (PGM) miners and recycling facilities are losing ~$2 billion (~10% of the total market value) of PGM annually in wastewater and tailing. The membrane biofilm reactor (MBfR) is a modular biotechnology which [...]

Energy Generation from Carbonaceous and Nitrogenous Pollutants via Ammonium, Methane, and Carbon Dioxide Reformation

Lee P-H, Ni M., Xu L., Dong F., The Hong Kong Polytechnic University, HK

An unprecedented integrated electrodeionization–solid oxide fuel cell (EDI–SOFC) system is developed for energy capture from carbonaceous and nitrogenous pollutants from wastewater. The feature of this system is that both carbonaceous and nitrogenous pollutants can be [...]

Synthesis of nano-hydroxyapatite from a biogenic waste for the removal of manganese from wastewater

Amuda O.S., Sanni K.A., Kolawole L.L., Ladoke Akintola University of Technology, NG

A novel Hydroxyapatite nanopowder prepared from a biogenic waste, shell of a gastropod, by hydrothermal method was used for adsorption of manganese ion in wastewater. The nano-Hap produced was characterized using XRD, FTIR and SEM. [...]

Biofilm Floc Nanostructures in Biological Wastewater Treatment in Fisheries

Shriniwas B.D., Sharma R., RTM University of Nagpur, IN

Biological wastewater treatment modelling has become and important tool in process engineering. There are state of the art activated sludge models (ASMs) available, which have found wide application in the engineering community. Biofilm nanomodels have [...]

Enviroquip Membrane Bioreactor Systems – Novel Wastewater Treatment Process for Enhanced Nutrient Removal

Zhang K., Lewis C., Swanson M., Ball A., Enviroquip, US

Traditional wastewater treatment technologies are not sufficient in protecting sensitive receiving waters. Agencies are required to meet Enhanced Nutrient Removal (ENR) limits that are increasingly difficult to achieve (e.g. 3.0mgN/l and 0.1mgP/l). Various techniques are [...]
