Producing methods:
Carbonization Process:
Natural soda is firstly dissolved into solution (NaCO3) and filtrated. The clear solution is then put into carbonizing tower accordingly.CO2 is compressed and  bubbled up from the bottom of the tower, After carbonization, the solution will be flowed from the bottom and separated, Dried to the finished product.
