| Summary: | The immobilization of whole cells is an important technique which provides alternative
solution in the field of wastewater treatment for the purification of wastewater
contaminated with various materials, such as organic compounds, inorganic compounds,
metals, and so on. The immobilized cells are biocatalysts which can easily be separated
from treated water without a setting step and such can be repeatedly used without
washing out from the systems. The processes using immobilized cells have been studied
and applied to practical treatment systems. An effective way of removing ammonia
nitrogen from aqueous solutions is the utilization of immobilized cells because of high
cell concentration, long retention time of biomass in the system, rapid separation of cells
from liquid and ability to scale up the process. These immobilized catalyst systems are
therefore proposed as potential methods for the treatment of various types of wastewater
from low to high strength. |
