ABSTRACT:
A method for producing a string-shaped bacteria bed having many loops of fiber on the whole surface thereof, which is used for sewage or wastewater treatment, characterized by preparing a narrow strip of cloth made from a thermoplastic material, having many loops of fiber on the obverse thereof, and heating the reverse thereof having no loops of fiber by contacting it with a heating rod while tensing and drawing it diagonally, thereby the strip of cloth is diagonally curled and stranded by heat to form a string having many loops of fiber on the whole surface thereof. In such a method, the string, having high holding capacity of bacteria colony, is obtained by simplified installation.
