Abstract
The present invention relates to magnetic carriers in which microorganisms requiring carriers for their growth in the step of treating wastewater have been immmobilized, a process for producing the carriers and a method of treating wastewater. The present invention provides microorganisms-immobilized carriers with a high amount of microorganisms immobilized for use in wastewater treatment, the movement of which is controllable in a treatment chamber by magnetic force. Further the present invention provides a process for producing said carriers easily and a method for treating wastewater efficiently.
