Application and development of luffa calindrical as bio-carrier in wastewater treatment

Bio-carrier is the core of biofilm treatment, which has a direct impact on the wastewater treatment. The natural fiber, luffa cylindrical, a widely planted agricultural product in China, has many advantages such as good hydrophilicity, biocompatibility, special porous structure, suitable surface area and shape, is an excellent environmental and sustainable biofilm carrier, will has very broad application prospects in wastewater treatment. Luffa cylindrical carrier has been widely studied in wastewater treatment, such as heavy metal waste water treatment, domestic wastewater nitrogen and phosphorus removal treatment and dyeing wastewater treatment. The experimental results showed that luffa cylindrical had high and stable treatment efficiency, microorganism easily inhabited it.
