Abstract
Recovery of nutrients from the manure wastewater has a potential for cost saving in the treatment process. Utilizing the recovered nutrients help reducing the amount of chemical fertilizer in an agriculture. The objective of this research is recovering nutrients from pig farm wastewater via the adsorption of various zeolite and this zeolite compound as organic fertilizer in growth of Green mustard. The objective of this research is optimizing the absorption of the total nitrogen and phosphorus of zeolite under various parameters, including the zeolite weight, the adsorption time, Azotobacter addition and the aeration. Results showed that the rate of 30g zeolite with supplementation of 5ml microbial was aerated in 72 hours for the best efficiency. After 21dates of growth, combination of chemical fertilizers and organic fertilizers mentioned the great products on both height and total harvested weight.
