    The present invention relates to magnetic carriers at a content of about 1 to 3 %, in which microorganisms requiring carriers for their growth in the step of treating wastewater have been immobilized, a process for producing the carriers by double-tubular nozzle and a method of treating wastewater. The present invention provides microorganism 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.
