9 inch Fine Bubble Disc Diffuser With EPDM Membrane For Water Treatment


Brief Introduction


Each strong EPDM (rubber) membrane is composed of up to 1000 tiny holes that release thousands of micro bubbles when compressed air inflates the disc. Energy saving design requires only 0.5 CFM of air supply for proper operation. For steep slope and deep water applications consider an aeration disc diffuser system as it provides fine bubbles from one location.
The self-cleaning flexible membrane openings prevent clogging in the dirtiest of lakes. Immersion in the muddiest of pond bottoms even where the water is dirty or brackish will not hamper the performance of the disc. Salt water or hard water or sludge thickened basins are not a problem for these powerful diffusers.
Most aerating bubbles produced with the powerful micro bubble technology are only .5 to 1.0 millimeters in diameter. The fundamental decrease in bubble size dramatically increases oxygen transfer rates. This will provide your pond with the most in aeration efficiency. The male connection is ¾” threads.
These rugged assemblies are ideal for updating and retrofitting worn-out, clogged or broken airstone type diffusers. No more airstone acid cleaning or frequent replacement necessary.
Flexible 7” or 9″ diameter membrane disc creates a strong, reliable bubble column for efficient lifting volume and aerating action.



Manufactured by compression molding with a standard cure,low plasticizer content, and 1mm or 2mm perforations.Compression molding with modern equipment utilizing individual thermocouples and vacuum technology ensures a repeatable very high quality product.



Silicon membranes offer high temperture resistance ,and chemical resistance that differs from other products .Silicon is an inorganic ,and therefore offers excellent resistance tomany organic wastes.Our formulationn is designed to resist tearing and creep,while producing fine bubbles at a modest headloss.



The PTFE surface layer protects the EPDM substrate from chemical attack,while at the same time significantly reducing surface fouling on the membrane.we except to learn that PTFE-coated EPDM membranes outlast standard EPDM,thereby reducing the life cycle costs even further .It is used by major cities worldwide due to the anticipated life cycle cost benefits and reduced maintenance.
