The OTT Tube Diffuser is a state-of-the-art aeration solution designed to enhance the efficiency and effectiveness of wastewater treatment processes. This advanced system has been developed to provide optimal oxygen transfer and ensure the aerobic conditions necessary for the biological treatment of wastewater. With its innovative design and robust construction, the OTT Tube Diffuser is suitable for a wide range of applications, including municipal and industrial wastewater treatment plants.
Our product lineup includes three distinct types: Standard 2 Tube Diffusers, Magnum Tube Diffusers, and One X Tube Diffusers. We also provide custom lengths, personalized colors, logos, and other specific printing options tailored precisely to your specifications.
Principle of Operation
The principle of operation of a tube diffuser in aeration systems is based on the distribution of air through a perforated tube to create fine bubbles, which enhance oxygen transfer efficiency in the water.
Key Steps:
Air Supply
Compressed air is supplied to the diffuser, typically involving blowers or compressors.
Air Distribution
The air enters the tube diffuser, which has numerous small holes or slits.
Bubble Formation
Air passes through the perforations and is released into the water as fine bubbles.
Bubble Rise
Fine bubbles rise slowly to the surface, creating a large surface area for oxygen transfer from air to water.
Oxygen Transfer
As bubbles rise, oxygen is transferred from the air bubbles to the surrounding water, increasing dissolved oxygen (DO) levels for aerobic wastewater treatment.
Mixing
Rising bubbles create vertical mixing in the water, ensuring even distribution of oxygen and preventing stratification.
STANDARD 2® Diffusers
- The OTT STANDARD 2 tube diffuser is ideal for retrofitting existing wastewater treatment facilities. It features patented engineering, including an integrated air channel for uniform air flow and a membrane mounting ridge for secure, wrinkle-free positioning.OTT diffusers provide highly efficient fine-bubble aeration. STANDARD 2 diffusers are easily installed on rectangular headers with 30, 40, or 45 mm (1.57″ or 1.77″) diameter outlet openings using double-threaded connectors available in PP-GF, stainless steel, or brass. They can also be installed on round headers with 20 mm (0.79″) diameter openings using a saddle-contoured adapter, ensuring secure mounting and resistance to high temperatures and formic acid.Available in stock lengths of 500, 750, and 1000 mm (19.69″, 29.53″, and 39.37″), STANDARD 2 diffusers can also be custom-fabricated to specific lengths for specialized applications.
MAGNUM® Tube Diffusers
- The OTT Magnum Diffuser represents the pinnacle of advanced aeration technology for wastewater treatment plants. Engineered for superior performance and efficiency, the Magnum Diffuser is designed to meet the rigorous demands of both municipal and industrial wastewater treatment applications. With its innovative features and robust construction, the Magnum Diffuser ensures high oxygen transfer rates, energy efficiency, and long-term reliability, making it an essential component for modern wastewater treatment processes.
OneX® Tube Diffusers
- OneX® tube diffuser features patented air ducts and membrane guide beads, ensuring optimal air distribution and secure membrane fit. Aerator strings connect to the main distributor via an adapter, reducing material costs and environmental impact. The one-piece PP carrier body is heat-resistant up to 120°C (248°F) and resistant to formic acid. Choose from EPDM (FLEXNORM®) or silicone (FLEXSIL®) membranes, with various perforations available. Usable lengths range from 500mm to 1,000mm, with custom lengths possible between 200mm and 1,650mm.
Features and Benefits
