Filtration and desalination solve different problems.
Ultrafiltration targets suspended particles. It is not intended to remove dissolved salts or reduce salinity. Reverse osmosis uses a membrane process to reduce dissolved salts.
The two may serve different stages of a treatment design. Selection depends on the actual analysis and the required treated-water quality.
