Abstract
A process for removing suspended particles and at least one ionic species from a feed water stream to produce a product water stream, the process includes the steps of forming agglomerates of the suspended particles in the feed water stream; passing the feed water stream containing agglomerated particles through a bed of particulate sorbent material so as to sorb the ionic species from the feed water onto the sorbent to provide a loaded sorbent and filter the agglomerated particles from the feed water using the bed of particulate sorbent material as a filtration medium to load the bed with the agglomerated particles, and thereby produce the product water stream; removing the filtered particles and the ionic species from the filtration medium; and re-using the regenerated sorbent in step b).
