dc.description.abstract | It was previously reported that struvite crystals could be formed in the aerobic composting reaction provided that Mg and P salts are added [Bioresource Technology 79 (2001) 129]. The formation of struvite crystals significantly reduced gaseous loss of ammonia and resulted in substantial increase in the ammonia content in the compost, attaining 1.5%. In this context, the present study was conducted to determine the optimal doses of Mg and P salts for struvite crystallization. It was found that cumulative ammonia production was about 33-36% of the initial total nitrogen in the aerobic composting reaction, irrespective of the amounts of Mg and P salts added. The theoretical doses for complete conversion of ammonia into struvite crystals seemed to be about 33-36% of the initial nitrogen. The addition of Mg and P salts at this level, however, caused adverse effects on the degradation of organic materials. Therefore, it was concluded that the optimal doses of Mg and P salts should be about 20% of the initial nitrogen in the compost mixture not to cause any harmful effects on the composting reaction.
