METHOD FOR MANUFACTURING MAGNETIC IRON OXIDE AND APPARATUS FOR REMOVAL AND RECOVERY OF PHOSPHATE USING THE SAME

摘要

The present invention relates to a method to manufacture magnetic iron particles, and an apparatus to remove and collect a phosphate using the same. More specifically, the present invention relates to the method of easily and simply manufacturing the magnetic iron particles having excellent phosphate adsorption and desorption ability, and the apparatus to remove and collect phosphate which is improved to improve efficiency of the magnetic iron particles. According to the present invention, the apparatus is able to simply manufacture the magnetic iron particles which is able to usefully be applied to an actual process since the magnetic iron particles have excellent phosphate adsorption and desorption ability and is also able to be recycled. Moreover, the present invention has an advantage of being able to secure a high purity phosphate and at the same time use the collected magnetic iron particles repetitively in case the apparatus to remove and collect the phosphate uses the magnetic iron particles.
