【 摘 要 】
The aim of this work is to evaluate the use ofnatural zeolites to remove the NH4+ that remains in effluentsfrom swine facilities which were submitted to physico-chemical and biologicaltreatments. Experiments were made in batch made adding 5% (w/w) of adsorbent(0.6-1.3 and 3.0-8.0 mm) to synthetic and real swine facilities effluents. Theresults show that ammonium removal is influenced by adsorbent particle sizeand the presence of other ions in the effluent. The adsorption equilibrium wasdescribed by Langmuir as well as Freundlich isotherms and the kinetic data fittedwell a pseudo-second order model.【 授权许可】
