1. Our goal was to quantify short-term phosphorus (P) partitioning and identify the ecosystem components important to P cycling in wetland ecosystems. To do this, we added P radiotracer to oligotrophic, P-limited Everglades marshes. PO4 was added to the water column in six 1-m enclosed mesocosms located in long-hydroperiod marshes of Shark River Slough, Everglades National Park. Ecosystem compo...

As the total number of persons held within the U.S. immigration detention system has grown, the number of detained persons with severe mental illnesses has grown correspondingly. Reports issued by the government, legal and human rights advocates, and the media have brought to light a problematic and growing detention system with pervasive legal and mental health care disparities. Described are ...

INTRODUCTION Under normal conditions in activated sludge, bacteria occur singly, in small chains or clumps. Under adverse conditions however, bacteria that grow in filaments begin to form longer chains called filamentous bacteria or “filaments”. Filaments can dominate in the wastewater treatment system under a variety of conditions. These conditions are usually less favorable for the floc-formi...

This study is the first attempt to investigate the effect of total hardness and ionic strength on coagulation performance and the floc characteristics of titanium tetrachloride (TiCl4). Membrane fouling under different total hardness and ionic strength conditions was also evaluated during a coagulation-ultrafiltration (C-UF) hybrid process. Coagulation experiments were performed with two simula...

The tube flocculator is used to study how fluid shear levels affect the settling properties of a flocculated alum-kaolin suspension. FReTA is employed to quantitatively compare the effects of varying fluid shear and hydraulic residence time on the sedimentation velocity distributions and the post-sedimentation residual turbidities of flocculated suspensions formed in the tube flocculator. Resul...
