During the sewage treatment process, the plastic Heilex ring, as the filler for the biological filter, can effectively improve the sewage treatment efficiency. Its large specific surface area and porosity provide sufficient attachment space for microorganisms, promotes the growth and reproduction of microorganisms, and accelerates the degradation of organic matter in wastewater. In addition, in the field of exhaust gas treatment, plastic Heilex rings are also used in absorption towers to effectively remove harmful substances in exhaust gas and improve air quality.

Application scenarios: sewage treatment, waste gas treatment, garbage leachate treatment, etc.

Areas: Environmental protection engineering, wastewater treatment, waste gas purification, etc.
