Paper Title:
Study of the Oil-in-Water Emulsion Treatment by Nonwoven Polypropylene Fiber
  Abstract

The feasibility of using nonwoven polypropylene fiber (NWPP) as the filter media to treat oil-in-water emulsion was studied. Both static adsorption experiments and dynamic filtration in coalescence bed were made. Due to the hydrophobic property of NWPP, the oil adsorption happened immediately when contacted with NWPP. The equilibrium was achieved after 50min adsorption. The Freundlich isotherm fits the experimental data well. The data was analyzed with three adsorption kinetic models: the pseudo first order, second order adsorption kinetics as well as the intra-particle diffusion models. The results showed that the second order adsorption kinetic was more accurate to correlate the experimental data. After the dynamic filtration processes using 4.0g NWPP, the oil removal efficiency could achieve 95%. It also found that the low flow rates would be better to treat oil-in-water emulsion in dynamic condition using NWPP as the filter media.
