The waste water of catfish aquaculture ponds contains the high amount of organic substances and nutrients. The criteria including DO, BOD5, COD, TDS, NH4+, total amount of phosphor and nitrogen exceed allowable threshold many times. The materials with specific surface area of 137.47 m2.g-1 prepared from peat was used to remove contaminants by bath condition. The water after treatment met the requirement of A level in QCVN 40:2011/BTNMT. Several criteria reduced almost completely such as the total amount of phosphor and nitrogen. The relevant conditions for treatment set as 2.0 gram of adsorbent in 1.0 L of waste water with equilibrium adsorption time. The removal efficient for contaminants reached 79.07%. It is possible to use the obtained material for treating the waste water of catfish aquaculture ponds in continuous flow condition.Keyword: adsorption nutrients, peat materials
