Wastewater treatment could be more effective using foamed plastic carriers in the moving bed biofilm reactor (MBBR) process, a research team has found. Their study showed that biofilm formation increased by 44 times compared with smooth plastic carriers.
Wastewater treatment could be more effective using foamed plastic carriers in the moving bed biofilm reactor process, a research team has found. Their study showed that biofilm formation increased by 44 times compared with smooth plastic carriers.
The moving bed biofilm reactor process purifies wastewater by putting these carriers in motion to get the biofilm's microorganisms into greater contact with organic matter and other impurities. The more biofilm that can be attached to the plastic carriers, the more microorganisms that are available to clean the wastewater.
Moreover, adding waste biomass such as composted seaweed when foaming further enhanced the performance of the foamed plastic carriers, especially in terms of nitrate removal during the MBBR process. Researchers showed that biofilm formation can be controlled with laser light in the form of optical traps. The findings could allow scientists to harness biofilms for various bioengineering ...
