Membrane technology has been widely used in gas separation, material separation and water treatment as a new
separation technology. Membrane technology increasingly shows its important role and a bright future. This paper focused
on membrane technology and apparatus, and reviewed achievements on patents of wastewater treatment by
membrane technology, which contains nanofiltration (NF), ultrafiltration (UF) and reverse osmosis (RO). Membrane
technology is an attractive technology that needs further research efforts and industrialization. However, membrane fouling
still remains a major problem for all membrane reactors. Discussions are also made on how to resolve membrane fouling
for wastewater treatment.
Keywords: Membrane technology, wastewater treatment, membrane fouling, prospect.
