Modelling Of Dreissenid Mussel Impacts On Lake Michigan, Chunqi Shen
Theses and Dissertations
Invasive dreissenid mussel appear to have profoundly altered Great Lakes food webs and nutrient cycles during the past several decades. Recent declines of phytoplankton were supposed to be highly related with the increase of mussel population. These phytoplankton declines were further found to be coincident with declines in the abundance of planktivorous fish. In addition, the resurgence of Cladophora in Great lakes was estimated to be associated with the high density colonization of mussels. More light is available at lake bottom due to the mussels’ graze effect. The mussels further promote Cladophora growth by fertilizing it with nutrient-rich excrement. And …
Influence Of Permeate From Domestic Reverse Osmosis Filters On Lead Corrosion And Leaching From Plastic Pipes, Jyotsna Shrestha
Influence Of Permeate From Domestic Reverse Osmosis Filters On Lead Corrosion And Leaching From Plastic Pipes, Jyotsna Shrestha
Theses and Dissertations
Reverse Osmosis filters are gaining popularity nowadays, in domestic water supply system, to meet the increasing demand of pure and improved drinking water. There are various types of domestic RO filters with varying sizes, capacities, and treatment stages available. However, there exist a few concerns regarding the RO treatment system. One of the major issues in the quality and distribution of drinking water is the corrosive water that the RO system produces. Therefore, this research herein tends to focus on the corrosive effect of the permeate water on lead metal, as lead is considered a serious problematic drinking water contaminant. …
