Preparation of Alternative Fertilizer from Municipal Wastewater and Swine farm Wastewater and Water Supply Sediment
Keywords:
Water supply sediment, Alternative fertilizer, AdsorptionAbstract
This research aims to utilize water supply sediment (WSS) by adsorption of nitrogen and phosphorus nutrients in domestic and swine farm wastewater for using as alternative fertilizer. Powder-WSS and bead-WSS were prepared and optimum condition of adsorption in solution were investigated by batch experiments. The results revealed that the ammonium, nitrate, and ortho – phosphate adsorption capacity of powder-WSS were 0.812, 0.227 and 1.507 mg/g respectively and a bead-WSS were. 0.614, 0.108 and 1.021 mg/g respectively. After that, the alternative fertilizer was prepared from the adsorption process of powder-WSS and bead-WSS in the mixed wastewater of domestic and swine farm wastewater at ratio 1:1 by volume. The analytical results of chemical properties revealed that the total percentage of N and P were nearly the organic fertilizer standard value and the organic matter was 0.14 – 1.64 % w/w
