Bioaerosol emissions from activated sludge basins: Characterization, release, and attenuation

Characterization of aerosol emissions from wastewater aeration basins.

UNLABELLED The emission of particulate matter (PM10 and PM2.5) and ammonia (NH3) by aeration processes at wastewater treatment plants (WWTPs) with and without odor control units was examined. Local concentrations of PM2.5, PM10, and NH3 at the aeration basins were within urban ranges. Emission fluxes of NH3 and PM2.5 for a medium-sized WWTP were determined to be 136 g day(-1) and 43 g day(-1), ...

Bioaerosol emissions from a suburban yard waste composting facility.

The purpose of this study was to assess worker and community exposure to bioaerosols emitted from a suburban yard waste composting facility in northern Illinois, USA. Characterization of on- and off-site viable bioaerosols was undertaken through a total of 288 on- and off-site Andersen samples conducted over 10 sampling days. A total of 46 dust samples and 38 Kramer-Collins spore samples were a...

Characterization of sludge from the extended aeration system to the activated-sludge system.

A Comparative Study of the Efficiency of Granular Activated Sludge and Common Activated Sludge in the Removal of Chromium (VI) from Synthetic Solutions

Introduction: Aerobic granules as a novel type of bio-sorbent have an excellent settling ability and high-porosity structure. This study investigated the feasibility of aerobic granules for chromium (VI) removal from synthetic aqueous solution and compare it with conventional activated sludge. Method: In this research the effect of some important parameters including pH (5, 7, and 9), initial c...
