Comparison of Dissolved Air Flotation and Sedimentation in Treatment of Typical North China Source Water
dissolved air flotation sedimentation turbidity
2009/11/16
The treatment of typical north China water by dissolved air flotation (DAF) and sedimentation process was examined. A pilot plant with a water treatment capacity of 120 m3/d constructed in the Jieyuan...
The Reactivity of Dissolved Organic Matter for Disinfection By-Product Formation
Natural organic matter (NOM) Chlorine disinfection by-products (DBPs) Activated carbon
2009/10/12
Dissolved organic matter (DOM) in 6 water samples collected from 4 surface waters were fractionated using some or all of 5 physicochemical separation processes (activated carbon and XAD-8 batch adsorp...
Dissolved Nutrient Behaviour along the Estuarine Salinity Gradient at the Gediz R (Aegean Sea, Turkey)iver Mouth
Nutrients Salinity gradient PCA Gediz River Izmir Bay
2009/10/9
The Gediz River is the largest fresh water source for ˙Izmir Bay. Several studies have been carried out on the river’s physical and biogeochemical dynamics. However, there has not been a particular ge...
Copolymers Formation by Photopolymerization of (Meth)acrylates Containing Dissolved Polyheteroarylenes
Copolymers Formation Photopolymerization (Meth)acrylates Polyheteroarylenes
2009/9/2
Radical photopolymerization of (meth)acrylates in the presence of dissolved polyheteroarylenes has been investigated. The kinetics of radical polymerization of unsaturated monomers in the presence of ...
Electrochemical Oxidation of Dissolved Carbon Monoxide on Gold Electrode in Alkaline Medium
Electrochemical Oxidation Gold Electrode
2009/7/28
The study of the oxidation of dissolved CO is not
much seen in the literature probably due to the
strong adsorption of CO on platinum metals in acidic
media. This work was thus undertaken to study ...
Effect of the Pore Size of Microfilters in Supercritical CO2 Bubbling on the Dissolved CO2 Concentration
supercritical CO2 bubbling the concentration of dissolved CO2 pore size of microfilters
2009/5/20
The effect of the pore size of microfilters installed in a supercritical (SC-) CO2 bubbling device on the concentration of CO2 dissolved in the solution was investigated. Dissolved CO2 concentration i...
