The Simultaneous Recovery from Stock Raising Drainage of Phosphorus and Potassium
MetadataShow full item record
Zirconium-based adsorbent having 150μm~300μm of diameter made by using the biomass which was not used at room temperature. Phosphorus adsorption was performed using fluidized bed reactor of lab scale for the biological treatment water of stock raising using this adsorbent. The quantity of adsorption was 0.9 mol/kg, and consecutive treatment was possible until during 10days which achieved 80% removal rate. Desorption operation allowed adsorption repeatedly. In addition, the desorption rate was 90%. Simultaneous recovery of phosphorus and potassium can be possible by use treatment water for desorption.
