Even with many impurities, fluoride removal is possible! Here are examples of continuous processing achieved during regeneration.
We would like to introduce a case where the water treatment adsorbent 'READ-F(HG)' was used for fluoride treatment at a semiconductor factory. In this factory, it was necessary to treat wastewater containing fluoride derived from hydrofluoric acid, and after coagulation and precipitation treatment with calcium, advanced treatment was carried out using the adsorbent. Since wastewater is continuously generated, treatment was conducted using multiple towers, allowing for ongoing processing even during regeneration. Additionally, because it can also be utilized as a safety device, it has become possible to reduce operational costs through extended regeneration cycles. 【Case Summary】 ■Challenges - There was a need to treat wastewater containing fluoride derived from hydrofluoric acid. ■Results - Continuous processing was achieved even during regeneration. - It became possible to reduce operational costs through extended regeneration cycles. *For more details, please refer to the related links or download the materials for confirmation.
