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. [...]

Photocatalytic disinfection of E. coli using tourmaline-N-doped TiO2 composite

Tzeng J-H, Lin Y.-T., Weng C-H, National Chung Hsing University, TW

Neither the microbicidal mechanism of TiO2 under visible radiations nor their potential effects in the light intensity have yet been well established. In this paper, the photocatalytic inactivation of bacteria was investigated using E. coli, [...]

Fabrication and Testing of a Miniaturised Water Quality Monitoring pH and Conductivity Sensors

Banna M.H., Najjaran H., Sadiq R., Rodriguez M.J., Imran S.A., Hoorfar M., University of British Columbia, CA

Development of cost-effective, durable and sensitive on-line water quality monitoring sensors that can be installed across the water distribution network has attracted attentions to increase the frequency of monitoring and hence reduce the risk of [...]

An integrated approach for industrial water systems optimal design

Porzio G.F., Alcamisi E., Matino I., Colla V., Scuola Superiore Sant'Anna, IT

A novel approach is presented for integration of traditional water pinch technology to include detailed waste-water treatment systems models. The theoretical framework as well as examples for practical application of the novel approach will be [...]

Innovative Treatment of Shale Fracturing Flowback and Produced Water for Reuse or Discharge

Pakzadeh B., Mastin B., Chatterton B., Vaillancourt A., Renew J., Wos J., Philbrook D., Min J., Wardle C., Southern Research Institute, US

Southern Research Institute, with project partners M2 Water Treatment, Inc. and BKT United received an award from Research Partnership to Secure Energy for America to develop an innovative, cost-effective, and robust approach for shale fracturing [...]
