  Abstract

The generation of livestock wastewater in Korea amounts to 130,000m3/day, 0.43% of the total waste water volume, but which corresponds to 8.6% of total BOD loading. furthermore this wastewater contins a large amount of nitrogen and phosphorus that are major causes of eutrophication in rivers and lakes. The average volume of livestock wastewater in a Korea's single farm is only 2.5 m3/day, which necessitates development of a simple and economical process for the removal of nitrogen and phosphorus. Introduction of fileration method removes more than 90% of suspended solids. Subsequent application of reverse osmosis removes more then 95% of total nitrogen and phosphorus in the wastewater. The effluent of this treatment will yield less than 200 mg/L of total nitrogen and 1 mg/L of total phosphorous, which are lower than 260 mg/L of total N and 50 mg/L of total P, the regulation values of Ministry of Environment, Korea. Treating 2 m3/day of livestock wastewater was found to be feasible with the application of filtration and reverse osmosis and the electrictiy requirement was estimated to be about 30 Kwh/month.
