抄録

<p>Shortage of phosphate ore used in fertilizers and industry is a worldwide problem. On the other hand, excessive residual phosphate in closed water areas, such as lakes and marshes, causes eutrophication problems, resulting in too many nutrients in seawater and river water than in natural conditions. Based on the current situation, we guess that developing a method to recover phosphate from closed water areas could solve the environment, the resources, and the food problems. This study aims to investigate the mechanical system for efficient phosphate recovery in terms of eco-design. The dynamic performance is estimated regarding recovering calcium phosphate using the basic experimental apparatus. Here, the sorbent as calcium carbonate in modeled agricultural water was used. Through our tests, we found that about 90% of phosphorus in closed water areas in 4 min would be recovered. Finally, based on the experimental results, we estimated the eco-burden during the operating performance based on the LCA methodology. Consequently, approximately 66% against the conventional achieve CO2 mitigation.</p>
