Title:
METHOD AND DEVICE FOR FILTRATING SEWAGE FLUID
Document Type and Number:
WIPO Patent Application WO/2002/020123
Kind Code:
A1
Abstract:
A method of filtrating sewage fluid capable of not only eliminating the use of a pump and simplifying a mechanism for the filtration of fluid but also completely eliminating the need for considerations to the fluid resistance and heat resistance of the pump, comprising the steps of, by utilizing a negative pressure caused by the decompression, leading sewage fluid (11) into a decompressed leading-in tank (13) decompressed by a decompression mechanism (28) connected thereto, disposing a filtrating means (18) for the sewage fluid (11) in a fluid passage ranging from the inlet side to the outlet side of the sewage fluid (11), and filtrating the sewage fluid (11) by a filtrating means (18), whereby, even if large particles and chips are present in the sewage fluid, the sewage fluid can be transferred, the sewage fluid can be transferred rapidly to the decompressed leading-in tank of the sewage fluid by a decompression means for rapid filtration, and the waste remaining in the decompressed leading-in tank after the filtration can be dried easily.
