Description

Filtration devices

The present invention is very advantageous in that the filtering efficiency of the raw water is excellent, and in particular, since the filtration casing rotating in order to clean the fiber bundle is stopped in the middle, the filtration casing is continuously rotated, The present invention relates to a filtration device capable of continuously filtering the foreign matter contained in the raw water, thereby greatly improving the filtering efficiency of the raw water.

In the water treatment process of a water treatment plant, pretreatment prior to filtration of floating matters and advanced treatment of various waste water and wastewater (ie, activated carbon, ozone, photocatalyst, membrane separation treatment), or water treatment for recycling purposes, A micro filter is used as a device for filtering suspended solids.
The microfiltration device used for this purpose has a structure in which the pore structure of the filter for filtering is fixed to a fixed size. Therefore, if the pores are clogged by the filtered contaminant after a certain period of operation, It was extremely low that most microfiltration devices had to be replaced.
The reason why the conventional filtration apparatus is inferior in the backwashing efficiency is that the pore structure is not changed even during backwashing as in filtration. As a result, the contaminants stuck in the pores of the filter are not easily washed and the backwashing efficiency is low .
In order to overcome such a problem, recently, some of the raw water introduced at the time of pressing the flexible weft filter is increased in filtration area through the upper and side surfaces of the compressed filter layer to increase the processing capacity, (VPMF) capable of side stream filtration and cloth flow filtration, which is effective for filtration of high-concentration raw water by returning to the raw water tank along the concentrated water discharge pipe, is disclosed in Korean Patent Registration No. 10- 0.0 > 0405152. ≪ / RTI >
However, in the case of Korean Patent Registration No. 10-0405152, in order to backfilter a filter layer composed of a plurality of flexible weft filters contaminated with suspended solids, the filtering device is shut down, There is a problem that the filtration efficiency of the raw water is deteriorated because the filtration apparatus must be operated again after the sifter filter is backwashed.
