Based on the effects of skim components on ammonium removal as well as the current processing technology, a new process-intensified technology of removing ammonia from skim by air stripping on rotating packed bed was proposed. The experiments were conducted on a wave-thread packed Rotating Packed Bed (RPB) under atmospheric pressure, suggesting that, in terms of order of importance, the ammonium concentration of feed-stock (x(w)), the average ultra-gravity factor (beta), feed-stock flux (L), and gas flux (G) had significant impact on ammonium removal rate (eta) and the ammonium concentration of products (x(D)). In the experiment, mass-transfer coefficient in gas phase (k(y)a(e)) increases with the increase of beta, G/L, and L. The ammonium concentration of products decreases with the increase of beta, G/L and the increase of L. The ammonium concentration of products would be as low as 0.10% and the ammonia removal rate would be 63.21% when skim temperature was 25 degrees C, x(w) 0.28%, beta 133.2, and G/L 15.0 m(3) . L-1. Experiment results indicated that the proposed technology for removing ammonium from skim on a rotating packed bedwould be a newprocess-intensified technique compared with traditional aeration process and centrifugal atomization method.
