ABSTRACT:
A process and system for separating solids from concentration soda ash solution is disclosed. In the process, a soda ash solution feed stream containing solids and other impurities is treated with a chemical coagulant to create solid particles having a diameter greater than 5 microns. Treated feed stream is passed through a microfiltration membrane which physically separates the solids from the soda ash solution. Commercially available microfiltration membranes having a pore size from 0.5 micron to 5 microns may be used. Solids are removed from the membrane surface by periodically backflushing the microfiltration membranes and draining the filter vessel within which the membranes are located. The dislodged solid material within the filter vessel is flushed removed from the filter vessel for further processing or disposal.
