In the field of water treatment, ozone has emerged as a powerful oxidizing agent, widely used to eliminate contaminants, disinfect water, and improve overall water quality. However, the high oxidative potential of ozone presents unique challenges for traditional packing materials, such as rapid degradation, corrosion, and reduced performance over time. To address these issues, ozone-resistant saddle ring packing has been developed as an advanced solution, offering exceptional durability and efficiency for water treatment facilities. This specialized packing is designed to withstand the harsh conditions of ozone-based treatment processes, ensuring stable and long-term operation in various water purification systems.

Superior Ozone Resistance: The Core Advantage
At the heart of ozone-resistant saddle ring packing lies its unmatched resistance to ozone-induced degradation. Unlike conventional materials like ordinary plastics or uncoated metals, this packing is engineered using high-purity, ozone-stabilized materials. Common options include polypropylene (PP), polyvinyl chloride (PVC), and 316L stainless steel, each chosen for their inherent stability against ozone molecules. These materials form a robust barrier that prevents ozone from breaking down the packing structure, avoiding surface cracks, porosity growth, or material brittleness. This resistance ensures the packing maintains its original shape and surface area even after prolonged exposure to high-concentration ozone, thus preserving critical performance metrics such as mass transfer efficiency and hydraulic conductivity.
Optimal Hydraulic and Mass Transfer Performance
Beyond ozone resistance, the design of ozone-resistant saddle ring packing prioritizes optimal hydraulic and mass transfer efficiency. Its unique double-arc saddle shape creates a balanced flow path for both liquid and gas phases. As water flows through the packing bed, the curved surfaces promote uniform distribution, minimizing wall flow and channeling that can reduce treatment effectiveness. Additionally, the structured surface of the saddle rings increases the specific surface area, enhancing the contact between ozone and water molecules. This design not only improves gas-liquid mass transfer but also ensures consistent flow distribution across the entire packing bed, leading to more thorough oxidation of contaminants and better overall water purification results.
Long-Term Reliability and Cost-Effectiveness
For water treatment facilities, long-term reliability is a critical factor, and ozone-resistant saddle ring packing excels in this aspect. By resisting ozone-induced degradation, the packing significantly extends its service life compared to conventional materials, which may need replacement every 1-3 years. This reduces maintenance frequency and associated costs, including labor, downtime, and material expenses. Moreover, the packing’s structural stability and low pressure drop contribute to energy efficiency, as pumps and blowers require less power to operate. Together, these features make ozone-resistant saddle ring packing a cost-effective choice for both new installations and retrofits, providing a higher return on investment over the system’s lifecycle.
