Abstract: A method for recovering catalytic metals from fluid compositions containing catalytic metal colloids. Fluid compositions such as aqueous rinse solutions or dragout baths containing catalytic metal colloids are passed through a porous metal filter that entraps the catalytic metal colloids. The catalytic metal colloids have a high affinity for the porous metal filter in contrast to other components of the fluids. The other components of the fluids pass through the porous metal filter while the catalytic metal colloids concentrate on the porous metal filter. The catalytic metal colloids that are captured on the porous metal filter are removed from the filter by backwashing the filter with a gas and/or a liquid. The backwashing forces the catalytic metal colloids off of the porous metal filter and through a solids discharge valve and into a solids collection container. The method is economically efficient with high catalytic metal recovery and is environmentally friendly.
