Defluorination mechnical filter tanks CS with rubber liner 1.0Mpa 36m3/h
Introduction
The deflurination filter removes fluorides with activated aluminum oxide absorbent, that are widely applicable and efficiently. As an amphoteric matter, activated aluminum oxide features ion exchange in water and with isoelectric point at about pH=9.5. When the PH of water is less than 9.5, anion can be absorbed and when the PH of water is larger than 9.5, kation can be absorbed. Therefore, in acid solution, activated aluminum oxide is anion exchanger, being selective for fluorine.
The Fluorine-contained water is removed by activated aluminum oxide and form in-dissolvable fluoride. When defluorination capability decreases to certain limit, or to say saturated, It can be recovered with regeneration agents, defluorination capability of the absorbent is recovered. Aluminum sulfate is adopted for regenerating cleaning at the ratio of 60:1 of the quantity of aluminum sulfate and that of defluorination amount. Regeneration concentration is 1%-2%. After operation of 3-4 months, use HCL solution of concentration of 3.5% to clean and then rinse with defluorination water for 8-10 minutes.
