This paper describes a layer-by-layer (LbL) method to sandwich Linde type A (LTA) zeolite nanoparticles between two polyelectrolytes, polyacrylic acid (PAA) and polyethylenimine (PEI), on a polyacrylonitrile (PAN) support layer. The purpose of this LbL method is to make a Forward Osmosis (FO) membrane with high zeolite loading. This paper presents ...

This paper describes the use of microfiltration membrane for the filtration of colloidal activated carbon. Efforts were made to minimize head loss and small molecule adsorption. The effects of source water quality and particle size were evaluated. The presence of natural organic matter (NOM) proved to be a confounding factor. Two methods were test...
