Environmental Dynamics International (EDI) - Axius Water products

Material Features: High temperature resistance up to 350 °F (177 °C). Excellent uniformity and distribution of released air bubbles. Formulated for application specific condition. Good chemical compatibility in most municipal and industrial application. Available for tube and disc diffusers. UV protection inherent in the compound. Low dynamic wet pressure (DWP). Note: Not recommended for some ON/OFF applications.

Available for FlexAir Pro tube and panel diffusers. Maximum mechanical strength and properties—will withstand harsh wastewater environments. Smooth surface characteristics inhibit fouling and prevents build-up of bio-solids. Excellent durability and chemical resistance. UV protection to resist UV rays before start-up of the system. long-term stability in DWP. Tested with over 2 million on/off cycles. No extractable oil content.

Fine Bubble diffuser systems disperse the diffused gas volume to transfer an equivalent amount of oxygen as a coarse bubble system. The diameter of gas bubble has a dramatic impact on surface area. Comparing 1 cubic foot of air used in fine, medium, and coarse bubble systems demonstrates why fine pore diffusers optimize the use of air and reduce energy consumption. This subsurface aeration technology introduces air into water via very small (or fine) bubbles ( The primary advantage of fine bubble technology is its high efficiency, capable of providing up to 10 lb/O2 Hp-Hr, making it 40–60% more efficient than most other aeration solutions.

62 mm and 91 mm diameter tube diffusers with standard length options from 250 mm to 1000 mm. Choice of PVC or CPVC material diffuser tubes available. Stainless Steel ¾” male pipe thread or plastic ¾” female pipe thread connections available. Premium quality membranes available in EPDM, PU, PTFE-infused Matrix Plus™, Silicone, or other specialty materials. Triple-check design minimizes entry of liquid/solids into air feed piping. High-capacity membrane option available for maximum air?ow and low operating pressure. Non-buoyant ?ow-thru design for reduced uplift and stress on mounting.

The EDI FlexAir Pro Magnum diffuser is a fine pore, flexible membrane diffuser that offers a superior design for optimal aeration capacity. It features a full circumferential perforated area and can be configured with standard or high-capacity perforations for increased aeration and mixing capacity and maximum SOTE. The diffuser is ideally suited for digesters and standard biological treatments that require efficient mixing and good oxygen transfer at lower operational costs.

Material Features: Glass-fiber-reinforced polypropylene body for maximum chemical, temperature, and UV resistance. Premium quality membrane materials available: EPDM, silicone, PTFE Matrix, specialty polymers. High-capacity membrane option available for maximumairflow and low operating pressure, Triple-check valve design minimizes entry of liquid/solids into piping. Ideal for on / off applications. Integral Saddle Mount provides ease of installation and maintenance with maximum mechanical strength. Mounts on any pipe material (PVC, ABS, CPVC, SS, etc.). 9” disc available to fit 3”, 4”, 90 mm, and 110 mm pipe sizes. 12” disc available to fit 3” and 90 mm pipe sizes; Patented EZ-Seal™ for quick membrane installation.

The EDI FlexAir Pro Disc Fine Bubble Diffuser provides both installation and operation flexibility and efficient oxygen transfer aeration. The dependable FlexAir Pro Discs, which have been installed in thousands of wastewater treatment plants for long-term operation, are made of fiberglass-reinforced polypropylene and come with a range of membrane solutions suitable for industrial and municipal wastewater treatment facilities.

FlexAir Basic conforms to the most common aeration specification with a quality, American-made (or UK-made) product. If your specification calls for a solvent-welded, disc diffuser-based system, you need to meet FlexAir Basic. Designed and built by EDI’s aeration engineers to meet the requirements of this common spec, FlexAir Basic is a high-quality product delivering high-efficiency aeration.

Material Features: Glass-fiber-reinforced polypropylene diffuser body for maximum chemical, temperature, and UV resistance. Saddle mount diffuser provides ease of installation/ maintenance along with maximum strength.
