Peracetic acid disinfection: An effective way to reduce antibiotics resistant bacteria from raw hospital wastewater

(Corresponding) Chhetri R., Sanchez Urbina D., Lindholst S., Rickers C., Elkær T., Gade H., Skaarup J., Andersen H.

Topic:

Wastewater treatment

Risk of infection from antibiotic resistant bacteria from wastewater to the workers in the plant can be reduced by disinfecting wastewater. Peracetic acid (PAA) was used to disinfect the raw wastewater from hospital in pilot scale experiment. Batch experiment was conducted in parallel to confirm...Read more

(Corresponding) Alitalo O., Rantalainen A., Pellinen J.

Topic:

Wastewater treatment

The incidence of cancer has increased worldwide and hormone antagonists are a group of pharmaceuticals used in the treatment of breast cancer. It is well known, that most of the pharmaceuticals are only partially removed or transformed during traditional wastewater treatment processes and the...Read more

Membrane Aerated Biofilm Reactor: A Correlation between Biofilm Thickness and Removal of Pharmaceuticals and Endocrinal Disruptor Compounds

(Corresponding) Sanchez-Huerta C., Fortunato L., Leiknes T., Hong P.

Topic:

Wastewater treatment

Removal of thirteen pharmaceuticals and endocrinal disruptor compounds via membrane aerated biofilm reactor was tested. MABR system demonstrated good management of nitrogenous nutrients. An increase in biofilm thickness enhanced the removal of analgesics, hormones, and disinfectants.

Keywords:

biodegradation, organic micropollutants, biofilm, nitrification

AliCy as Extractant to Remove Iron from Copper-Free Extreme AMD for Further Extraction of Zinc

Nobahar A., Melka A., Neves L., Carlier J., (Corresponding) Costa M.

Topic:

Wastewater treatment

A previous work showed that copper can be specifically extracted from acid mine drainage (AMD) classified as high-acid and extreme-metals (pH 1.19, ~63 g/L Fe, ~6.5 g/L Al, ~5.3 g/L Cu, ~1.9 g/L Zn and ~0.1 g/L Mn), using 30% (v/v) Acorga M5640 in Shell GTL (a kerosene like solvent) as extractant...Read more

Incorporation of negatively charged MWCNT-fGO self-assembled nanomaterials into PLA polymeric membranes for wastewater treatment

(Corresponding) Khalil H., Nassar L., Wadi V., Naddeo V., Banat F., (Corresponding) Hasan S.

Topic:

Wastewater treatment

The incorporation of nanomaterials in membrane’s matrix aims mainly to improve the properties of the membranes such as hydrophilicity, mechanical strength, thermal stability, water flux. Multi-walled carbon nanotubes (MWCNT) and functionalized graphene oxide (fGO) have recently attracted attention...Read more

Hydrogen and organic acids production from mesophilic and thermophilic dark fermentation of sugarcane vinasse without buffers

(Corresponding) Ribeiro J., Mota T., Oliveira V., Zaiat M.

Topic:

Wastewater treatment

The main objective of this study was to evaluate the valorization of vinasse dark fermentation (DF) through bioH2 and value-added metabolites production without buffers in two similar Upflow Anaerobic Sludge Blanket (UASB) reactors under mesophilic (U30) and thermophilic (U55) conditions. An...Read more

(Corresponding) Kerkez D., Pucar Milidrag D., Bečelić-Tomin M., Gvoić V., Kulić Mandić A., Leovac Maćerak A., Tomašević Pilipović D.

Topic:

Wastewater treatment

Water pollution is one of the most current problems related to human life and survival. The high degree of pollution of the human environment is contributed, among other things, by the discharge of industrial wastewater into rivers, among which wastewater from the graphic industry is of great...Read more
