How enzymes helped a semi-conductor fabricator achieve ~100% reduction in TDS and a more efficient process
A semiconductor fabricator producing 30,000 wspm generated 1.2 MM liters of 400 ppm H₂O₂ containing waste water per day. Removing the hydrogen peroxide in this waste stream with a conventional method used 352 MT of sodium bisulfite on an annual basis with a variable cost close to $600,000.
Using IFF’s OPTIMASE CA 800L catalase, the plant realized a significant saving in variable cost, without requiring any capital investment. In addition, only 3 MT of catalase was needed for treatment, leading to a greatly reduced logistics footprint (e.g., warehouse space and handling, truck movements). The use of catalase resulted in not only a nearly 100% reduction in total dissolved solids (TDS), bur also a more efficient ion exchange process and improved resin lifetime.
