Control of Odorants Emissions from Poultry Manure Using Jordanian Natural Zeolites

Abstract

Natural zeolitic tuffs from Tall Juhira (southern Jordan) have been investigated and tested for their odor removal capacity. Two types of Tall Juhira zeolitic tuffs were used in the odor sorption from animal wastes. The first type is the separated size fraction between 1 and 0.7 mm (TJ1), while the second type is the separated size fraction between 0.7 and 0.3 mm (TJ2). The effect of particle size was examined in the removal experiments. The main species identified in Tall Juhira natural zeolitic tuffs are: chabazite and – subordinately- faujasite and phillipsite. Zeolitic tuff trap and batch tests were performed to determine the effectiveness of Tall Juhira zeolitic tuffs in the reduction of the odor emission from natural broiler manure. The results were interpreted by using percentage removal curves and diagrams. By using TJ1 in zeolitic trap experiments, the removal percentages of NH3 ranged from 93 to 71, while by using TJ2 the removal percentages ranged from 96 to 81. In batch experiments, the use of TJ2 type shows a higher percentage of NH3 retention than TJ1 type for the same time. The odor panel results show that the control manure (untreated) has the highest odor intensity in all trails. In summary, it can be concluded that odor emission from animal waste can be effectively reduced using Juhira zeolitic tuffs.
