Title:
DEVICE FOR TREATING RADIOACTIVE DETERGENT DRAIN
Document Type and Number:
Japanese Patent JPH01173899
Kind Code:
A
Abstract:
PURPOSE:To extend the service life of filter media and to reduce the number of operators by laminating and packing filter medium unit formed by butting many spherical fiber lumps into net bags into a filter cylinder in one array in the filtration direction. CONSTITUTION:The filtration of the packed bed type filter of this treatment device is executed by the many spherical fiber lumps put into the net bags. Since waste liquid flows distributively among the respective spherical fiber lumps 11, solids are captured not only by the upper surfaces of the packed bed but also by the inside parts over the entire part of the filter media, i.e., the large solids are captured by the surfaces of all the spherical fiber lumps and the small solids are captured by the inside thereof. The life of the filter media is, therefore, much longer than the conventional packed bed type filter as well as the filter using the packed bed of the divided net bag type. The frequencies of exchanging the filter media are thus decreased.
