Dubhe DUDH Disc Diffuser: Maximum Aeration Performance & Efficiency—DUDH-9
The diffuser discs are strategically perforated with a multitude of tiny holes that release small bubbles when supplied with compressed air. These fine bubbles have a large surface area-to-volume ratio, allowing for efficient transfer of oxygen from the air to the water. The increased surface area ensures enhanced contact between the oxygen and the wastewater, facilitating the transfer of dissolved oxygen to support the biological processes within the treatment system.
The Dubhe DUDH Disc Diffuser is designed for maximum aeration efficiency. Its advanced engineering and precise distribution of fine bubbles across the diffuser discs result in high oxygen transfer rates. The uniform bubble distribution helps prevent the formation of dead zones or stagnant areas within the treatment tank, ensuring that all areas receive adequate oxygenation.
The diffuser discs are typically arranged in a grid pattern, and evenly distributed throughout the aeration tank. This configuration allows for optimal coverage and ensures that the entire volume of wastewater receives proper aeration, promoting effective biological treatment and minimizing the potential for odor generation.
Low Maintenance Requirements:
The device is designed to be durable and long-lasting, with low maintenance requirements.
High oxygen transfer efficiency (OTE)
Fine bubble diffusers generally work to treat water waste through OTE. However, with our products, it helps for a more enhanced process considering its specifications.
High Turbulence Generation:
The rotor is designed with several blades or vanes that are arranged in a radial pattern, creating a high degree of turbulence and mixing in the water as the rotor rotates.
Quiet Operation:
The Dubhe DUDH disc aerator is designed to operate quietly, which is important for wastewater treatment plants located in urban areas.
Corrosion Resistance:
The material used in the rotor is typically high-strength, low-alloy steel or stainless steel, which is resistant to wear and corrosion.
EPDM Membrane
Manufactured by a standard cure, low plasticizer content, and 1mm or 2mm perforations. DUBHE mold EPDM with modern equipment utilizing individual thermocouples and vacuum technology ensures a repeatable very high-quality product.
Diffuser Bases
The Diffuser Basesis molded with virgin polypropylene for extended performance, and is highly efficient with airflow performance of 1.5-2.5SCFM.
