JetFlex® HD 270 Disc Diffusers
Advanced Aeration Solutions for Enhanced Wastewater Treatment Efficiency
Optimize your wastewater treatment processes with Jäger's JetFlex® HD Series Fine Bubble Disc Diffusers, designed for superior oxygen transfer and operational reliability.
The Jäger JetFlex® HD Series Fine Bubble Disc Diffusers are meticulously engineered to deliver exceptional aeration performance in both municipal and industrial wastewater treatment applications. These diffusers produce fine bubbles, significantly enhancing oxygen transfer efficiency (SOTE) and reducing energy consumption. Their innovative design ensures reliable operation in both intermittent and continuous aeration processes.
Key Features of Disc Diffusers
- High Oxygen Transfer Efficiency – The precision die-cut openings facilitate superior oxygen transfer, leading to optimized wastewater treatment.
- Durable Construction – Equipped with a glass fiber-reinforced polypropylene body plate and ring, these diffusers offer enhanced strength and longevity.
- Versatile Membrane Materials – Available in various materials, including EPDM and Silicone, to accommodate diverse wastewater characteristics.
- Flexible Sizing Options – Active diameters range from 184 mm to 295 mm, allowing for tailored configurations.
- Efficient Design – Different orifice sizes adapt to various airflows, enhancing overall system efficiency.
- Easy Installation – Compatible with both 3-inch and 4-inch IPS pipes, as well as 90-mm and 110-mm diameter metric pipes of any thermoplastic material, facilitating straightforward integration into existing systems.
Applications
Wastewater Treatment
- Municipal wastewater treatment plants rely on disc diffusers for aeration in activated sludge systems to support microbial degradation of pollutants.
- Industrial wastewater treatment facilities use them for biological oxygen demand (BOD) and chemical oxygen demand (COD) reduction.
Sludge Stabilization
- Enhances aerobic digestion processes by supplying oxygen to break down organic matter in sludge.
Aeration of Rivers and Lakes
- Used in environmental restoration projects to improve dissolved oxygen levels in stagnant water bodies, reducing eutrophication.
Biogas Plant Operations
- Facilitates the pre-treatment of concentrate and leachate from biogas production processes, improving overall system efficiency.
Industrial Applications
- Pulp and Paper Industry: Ensures proper aeration in wastewater generated from paper production.
- Petrochemical & Refining: Used in ozone aeration for water treatment and neutralization processes.
- Food & Beverage Industry: Helps manage oxygen transfer in effluent treatment systems.
CO₂ Fumigation & Ozone Aeration
- Used in neutralization processes by aerating CO₂ into water to control pH levels.
- Ozone aeration applications help in advanced oxidation processes for treating contaminated water.
Protection of Water Bodies from Freezing
- Aerators are effectively used to create ice-free zones in ponds, artificial lakes, and industrial reservoirs. Thanks to the continuous air supply, they maintain water circulation, preventing ice formation
Advantages
Disc diffusers come with different membrane options tailored for specific applications:
EPDM: Best suited for municipal wastewater treatment.
Low Plasticizer EPDM: Ideal for food, beverage, and animal processing industries.
Silicone: Suitable for chemical, petrochemical, pulp, and paper industries.
Specific accessories for disc diffusers
As with all diffusers, we offer an wide range of accessories. EPDM holders, PVC saddles and saddle clamps for various pipe diameters are available for mounting the disk diffusers onto the pipework. A separately usable non-return valve is used to control the air volume flow in the event of a damaged membrane and in this case prevents sludge water from entering the piping system.
