Nitrification and denitrification in the activated sludge process
The characteristics of the single-sludge nitrification-denitrification process were investigated using influent organics as the carbon source and nitrate as an electron acceptor to see if any oxygen savings could be obtained. ...
A cost model for membrane filtration
A model is developed that calculates capital and operating cost of cross-flow membrane filtration as a function of relevant design parameters. An expression for capital cost is empirically derived from information gathered ...
Natural organic matter enhanced retention of atrazine by dialysis membranes: Implications for ultrafiltration and nanofiltration
Retention of atrazine from simulated surface water was measured using dialysis membranes with molecular weight cut-offs similar to those of pressure-driven ultrafiltration and nanofiltration membranes. Atrazine was ...
Fluid mechanics and particle transport in a channel with one porous wall: Application to membrane filtration
Fluid mechanics of a channel with one porous wall was studied from first principles as the initial step towards understanding polarization phenomena in membrane modules. A regular perturbation method was used to solve the ...
The effects of representing the spatial variability of aquifer characteristics on numerical ground water flow and contaminant transport modeling
The objective of the research presented here is to determine how the representation of the spatial variability of aquifer properties affects ground water flow and contaminant transport modeling at the United Creosoting ...
Analysis of groundwater mounding using a surface impoundment database and Monte Carlo simulation
A database for surface impoundments (SIs) consisting of hydrogeologic and operational parameters was developed and statistically analyzed. The database was used to evaluate infiltration, groundwater mounding, contaminant ...
