Abstract:
[Problem] To provide: an adsorbent which can reduce the total running cost of a water treatment apparatus while preventing membrane obstruction in a reverse osmosis membrane in advance and extending the usable life of the reverse osmosis membrane by selectively adsorbing specific suspended materials or soluble materials which cause membrane obstruction in the reverse osmosis membrane; and a method for preparing the adsorbent. [Solution] This adsorbent 21 preferably comprises a laminate in which, among thermoplastic resins having an average diameter of about 0.5-10 μm, nylon MXD6 resins are laminated, wherein said laminate has a packing density of about 0.20-0.40 g/mL and a specific surface area of about 0.33-6.54 m2/g.
