Model prediction and experimental studies on the removal of dissolved NH3 from water applying hollow fiber membrane contactor

► Mathematical model for degassing water using hollow fiber membrane contactor. ► Adsorption/desorption consideration of NH3 molecules within the pore walls. ► NH3 removal studied as function of feed concentration, flow rate and pH. ► 99% or more removals observed under varied feed concentrations and flow rates. ► Experimentally obtained removals observed to match with model predicted values.
