Disc Diffuser AS-DD350 Advantage
1.High Aeration Efficiency：The 12-inch aeration disc provides a large aeration surface area, facilitating efficient oxygen transfer. This significantly increases the dissolved oxygen levels in the water, enhancing microbial metabolism and organic matter degradation.
2.Uniform Bubble Distribution:This aeration disc produces uniform, fine bubbles, ensuring even oxygen distribution throughout the water. This ensures that all microorganisms within the reactor receive adequate oxygen, improving treatment performance.
3.Low Energy Consumption:Due to its optimized design, the 12-inch aeration disc provides efficient aeration with lower energy consumption, helping to reduce operational costs and increase the system's economic efficiency.
4.Durability:Typically made from high-quality materials, the aeration disc offers excellent corrosion and oxidation resistance. It can withstand the harsh environment of wastewater treatment for extended periods, reducing maintenance frequency and replacement costs.
5.Easy Installation and Maintenance：The 12-inch aeration disc features a simple design, making installation and maintenance straightforward. Its modular design allows for quick replacement and repairs, minimizing downtime and ensuring continuous system operation.
6.Reduced Sludge Production:Efficient oxygen transfer and microbial activity promote complete degradation of organic matter, resulting in reduced production of excess sludge and lowering sludge handling and disposal costs.
7.Environmentally Friendly:By improving treatment efficiency and reducing energy consumption, the 12-inch aeration disc helps to minimize the environmental impact of wastewater treatment, promoting sustainable development
These advantages make the 12-inch aeration disc widely used in wastewater treatment systems, significantly improving treatment effectiveness, reducing operational costs, and extending the lifespan of the system.
Disc Diffuser AS-DD350 Application
In the secondary treatment of pulp and paper industry wastewater, the AS-DD350 Disc Diffuser significantly enhances the efficiency and effectiveness of the process through its efficient working mechanism. These aerators are installed at the bottom of the treatment tank and connected to an air supply source, utilizing micro-pores in the EPDM diaphragm to generate fine and uniform air bubbles. This design increases the air-water contact area, which improves the efficiency of dissolved oxygen transfer. As dissolved oxygen levels increase, microbial activity in the tank is enhanced, effectively breaking down the high concentrations of organics, colorants, and chemical additives in the wastewater. The disc aerator not only supports the metabolic needs of the microorganisms and accelerates the degradation of organic pollutants, but also reduces the operating costs of the entire system due to its design optimizing energy use. Their clogging resistance and durability further reduce maintenance requirements and ensure long-term stable operation, making them a key technology solution for pulp and paper industry wastewater treatment.
