MICROORGANISM CARRIER FOR BIOLOGICAL TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To inexpensively produce a microorganism carrier used in a biological treatment apparatus in a size corresponding to properties of treated water by fixing the base end parts of a large number of projected parts having arcuate curved free ends comprising yarn materials projected radially from a core material having appropriate length to the core material by clamp yarns. SOLUTION: A microorganism carrier A is formed from a core material 2 having an appropriate diameterϕ1, a large number of tufted projected parts 1 formed from yarn materials 1' radially projected outwardly from the core material 2 so that the leading end parts of them are formed as arcuate curved free ends, clamp yarns 3 tightening and fixing the base end parts of the tufted projected parts 1 to the core material 2 and an adhesive for integrally fixing the clamp yarns, the base end parts of the tufted projected parts and the core material 2. The material forming the projected parts 3 and the clamp yarns is processed into a monofilament, multifilament or spun yarn shape of an org. fiber such as a natural fiber or an inorg. fiber such as a glass fiber or a mineral fiber and these filaments or yarns are used alone or in a mixed state.
