PURPOSE:To make a filtration wall flexible, elastic and suitable for use in a forced dehydration filtration by forming the filtration wall by concatenating split elements with a spring or spring-tensioned connecting material. CONSTITUTION:Split elements are connected by passing flexible wire W with one end Wa attached to an inner ring 8 through the through holes of the elements. The wire W is connected with a spring 11 in an arrangement hole 9a, which communicates to the through holes, provided in an outer ring 9. The other end of the spring 11, connected to wire Wb of the same type, is tensely fixed to a stopper 12. A split element 1 located at an inner-most circumference has an attachment concave groove 1a formed on an internal circumferential end face so that the split element may be engaged with a projecting line 8a of the inner ring 8. On the external circumferential end face of split element 6 located at an outer-most circumference, an attachment concave groove 6a which fits into an attachment projecting line 9a of the other ring 9 is provided.
