Non-targeted facilitation of primary sludge anaerobic fermentation by micro-aeration and the simultaneous nutrients transformations

Mohammed Mouhib

Anaerobic fermentation is a widely used technology for resource recovery from municipal sludge (e.g., primary sludge). Micro-aeration is an emerging strategy which can be incorporated into this technology. However, the effect of micro-aeration on the anaer ...

Selective elimination of enterovirus genotypes by activated sludge and chlorination

Tamar Kohn, Shotaro Torii

Enteroviruses, which are commonly circulating viruses shed in the stool, are released into the sewage system and only partially removed or inactivated, resulting in the discharge of infectious enteroviruses into the environment. Activated sludge and chlori ...

Effects of Anthropogenic Discharge and Hydraulic Deposition on the Distribution and Accumulation of Microplastics in Surface Sediments of a Typical Seagoing River: The Haihe River

Florian Frédéric Vincent Breider

Microplastics pollution in river systems has generated great concern; however, few studies have focused on the contributions of multiple influencing factors to microplastics in river systems. In the current study, we utilized data on microplastics in surfa ...

Present and past bio-available phosphorus budget in the ultra-oligotrophic Lake Brienz

Alfred Johny Wüest, Beat Mueller

A detailed budget of the fluxes of bio-available phosphorus (bio-P) was established for the ultra-oligotrophic Lake Brienz (Switzerland) and its catchment. Lake Brienz is a cold, deep oligotrophic peri-alpine lake that receives an annual load of approximat ...
