Current best practices in wastewater reclamation facilities include the use of ultrafiltration or microfiltration membranes.

Wastewater reclamation has become a viable alternative to supplement water supplies in water short areas. In particular, membrane treatment has played an important role in purifying the water cost effectively. Reverse osmosis (RO) membranes have been shown to significantly reduce total dissolved solids, heavy metals, organic pollutants, viruses, bacteria and other dissolved contaminants.
