Method for treating wastewater/water with membrane bioreactor

A method of wastewater/water treatment includes introducing an influent into a reactor so that a portion of contaminants in the influent is decomposed by microorganism in the reactor during a retention time of the influent in the reactor, and thus an effluent has a less amount of contaminants in comparison with the influent. The microorganism is grown fixedly on modified porous carriers in the reactor. The modified porous carrier contains a polymer foam and adsorbent particles entrapped in pores of the polymer foam, so that the modified foam not only has a large specific surface area, but also characteristics such as water affinity or an affinity to a certain type of contaminants. As a result, the efficiency of reducing contamination in the influent water is enhanced.
