Removal of Phosphorus from Water Using Marble Dust as Sorbent Material
Removal of Phosphorus Marble Dust Kinetic Model Pseudo Equation Isotherm Model
2013/3/11
The removal of phosphorus from water using marble dust as sorbent material was studied by conducting batch tests, kinetic sorption model and isotherm model. The kinetic sorption model based on a pseud...

Azolla Aquaculture Environment Fish Meal Replacement Oreochromis niloticus Nitrogen Phosphorus Nutrient Balance
2013/3/11
Nitrogen (N) and phosphorus (P) wastes produced by Nile tilapia Oreochromis niloticus L. fed Azolla, an aquatic atmospheric nitrogen fixing fern, was evaluated for 90 days in pond experiment. Six ison...
Estimation of Phosphorus Bioavailability in the Water Column of the Bronx River, New York
SRP TP OP Native Phosphatases Hydrolysis River Water Quality
2013/3/11
Phosphorus (P) is a primary limiting nutrient in rivers and streams, and excessive P results in eutrophication of freshwater systems, in turn, excessive algal growth/toxic algal blooms, oxygen depleti...
