Occurrence and removal of priority pollutants by lamella clarification and biofiltration

Occurrence and removal of priority pollutants by lamella clarification and biofiltration.

This study investigates the occurrence of all priority substances (n = 41) listed in the Water Framework Directive and additional substances (n = 47) in raw sewage, as well as the removal performance of lamella clarification and biofiltration techniques. Once the efficiency of both types of techniques has been assessed for typical wastewater parameters, the differences in each technique's abili...

Lamella Clarification and Biofiltration

9 This study investigates the occurrence of all priority substances (n = 41) listed in the 10 Water Framework Directive and additional substances (n = 47) in raw sewage, as well as the 11 removal performance of lamella clarification and biofiltration techniques. Once the efficiency 12 of both types of techniques has been assessed for typical wastewater parameters, the 13 differences in each tec...

Biofiltration vs conventional activated sludge plants: what about priority and emerging pollutants removal?

This paper compares the removal performances of two complete wastewater treatment plants (WWTPs) for all priority substances listed in the Water Framework Directive and additional compounds of interest including flame retardants, surfactants, pesticides, and personal care products (PCPs) (n = 104). First, primary treatments such as physicochemical lamellar settling (PCLS) and primary settling (...

Degradation and removal of organic pollutants by BaFe2O4 nanostructures, synthesis and characterization

BaFe2O4 nanostructures have been synthesized through a simple sonochemical reduction approach. X-ray diffraction characterization suggested that the product consists of cubic phase pure BaFe2O4. The as-prepared products were also characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). An X-ray energy dispersive spectroscopy (EDX) study further confirmed t...
