Filtering system

Abstract

Disclosed is an energy-saving and environmentally-friendly filtering system which minimizes energy consumption during a filtering process so as to dramatically reduce water treatment costs. The invention includes a water supply pot for storing water to be treated; a hollow fiber membrane module for filtering water supplied by the water supply pot, and a filtering fluid pot for storing filtering fluid resulted from the hollow fiber membrane module, wherein the hollow fiber membrane module includes a plurality of hollow fiber membranes so s to filter the water supply, and the pressure head of the water in the water supply pot plus the water pressure of the filtering fluid based on siphone principle is higher than the threshold membrane pressure generated by the hollow fiber membranes.

Description

technical field [0001] The present invention relates to a filtration system, and more particularly to an energy-efficient and environmentally friendly filtration system capable of minimizing the amount of energy required for filtration, thereby significantly reducing the cost of water treatment. Background technique [0002] Separation methods for water treatment that purify water by removing impurities from water include heating or phase change methods and filtration membrane methods. [0003] The filter membrane method is more beneficial than the heating or phase change method in that the process reliability of the filter membrane method is higher, because the desired water quality can be obtained by controlling the size of the pores of the filter membrane. Also, since the filtration membrane method does not require a heating process, it can be beneficially used for water treatment using microorganisms, which may be adversely affected when heated. [0004] Among the filtr...

AI Technical Summary

Problems solved by technology

[0008] However, both the conventional pressurized type and submerged type hollow fiber membrane modules require a relatively large amount of energy and high water treatment cost because of the need to artificially generate a pressure difference (ΔP: hereinafter referred to as is "differential pressure") to perform filtering

Moreover, conventional filtration systems have disadvantages in terms of environmental impact because of the large amount of energy consumed for filtration
