The present invention relates to a screen division type water strainer. According to the present invention, a screen is divided and arranged on two areas, and a filtering process and a backwashing process are performed so that surfaces of the whole area do not decrease, and the backwashing process can be easily performed since the distance from a backwashing arm to the end of the screen has decreased. Accordingly, disadvantages that filtering efficiency is low since impurities at the end of the screen far from the backwashing arm are not properly back washed can be solved. |
