The purpose of this study is to examine the water treatment system combining adsorbent and membrane separation. The powdered natural zeolite (-100+200mesh) was used as the adsorbent with the membrane systems of ultrafiltration and microfiltration. The experiments were performed by such operation factors as the particle diameter of zeolite, the concentration of ammonia nitrogen, the amount of zeolite and the difference of membrane.
As the results, the ultrafiltration membrane system with natural zeolite (10,000mg·l-1) gave as higher removal of ammonia nitrogen as 90% from the solution (ammonia nitrogen 10mg·l-1).
