アスア List of Products and Services

Introducing the "Asua Method for Dioxins." Due to the high toxicity of dioxins and heavy metals, certainty is required in all processes from removal to disposal. At Asua, we apply our proven method to create a negative pressure and humid treatment at the work site before washing. Additionally, the washing water, which becomes high-concentration sludge, is treated through detoxification, stabilization, and insolubilization before disposal. While thoroughly preventing contamination of the surrounding environment, our method can reduce time, personnel, and costs, making it very effective for safely dismantling waste incineration facilities. 【Features】 ■ Reliability ■ High efficiency ■ Low environmental impact ■ Significant work efficiency improvement ■ Cost reduction achieved *For more details, please refer to the PDF materials or feel free to contact us.
