Abstract

A membrane filtration system, capable of effectively removing foreign matter attached to a separation membrane while saving energy by reciprocating the separation membrane, includes a treatment bath, a membrane support frame disposed in the treatment bath, a separation membrane module installed in the membrane support frame, a reciprocating part connected with the membrane support frame to reciprocate the membrane support frame, a sludge floating part disposed on a lower end of the membrane support frame to float sludge accumulated in the treatment bath, and a control part controlling a reciprocating distance or frequency of the separation membrane module.
