Membrane Fouling And Cleaning Study For Drinking Water Treatment Using Integrated Membrane System

Membrane technology is being widely applied for water treatment system to enhance the conventional water treatment system. However, there are still some limitations in the application of membrane technology inspite of their advantages due to membrane fouling which resulting to lower production and h...
