Sanyo Electric recently announced that its Human Ecology Research Center of Sanyo R&D headquarters and Sanyo Aqua Technology have developed an efficient recycling system for hydrofluoric acid wastewater.

Based on Sanyo's proprietary wastewater treatment technologies designed for semiconductor manufacturing, the new system can efficiently improve the quality of treated water, regardless of the fluorite level of wastewater, while recovering high-purity fluorite.

The latest technology saves space and consumes less power than the conventional coagulation sedimentation-based wastewater treatment system. The new system can be applied to hydrofluoric acid wastewater emitted from not only semiconductor plants but also fluorinated gas treatment facilities.
