Product Description

Good Selling EPDM Membrane Disk Aerator Fine Bubble Disc Diffuser for Wastewater Treatment Aeration System

Fine bubble Disc Diffuser features a unique split pattern and slit shapes, which can disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency. A much highly effective and integrated check value enables the aeration zones to be easily shut down for air-on/air-off applications. The membrane disc diffuser can combines effective design, low installation cost, reliability and high performance in intermittent and continuous aeration process.

The purpose of Fine Bubble Disc Diffuser is to dissolve oxygen into waste water so that the microorganisms can utilize it while they break down organic material. Fine Bubble Disc Diffuser is a subsurface form of diffusion in which air is introduced in the form of very small bubbles to aid or enhance the treatment of wastewater.

 

Characteristic

• Ideal for air-on/air-off applications such as SBRs, aerobic digesters, and anoxic swing zones, as well as continuous operation

• Over 22 million diffusers installed in municipal and industrial applications worldwide

• Higher sustained efficiencies verified through 3rd party testing

• Advanced membrane perforation technique creates extremely fine, uniform bubble pattern for optimal oxygen transfer

• Low maintenance and long service life of more than 5 years

• Using imported raw material

Material: EPDM
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.

Material: Silicon
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.

Material: PTFE
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.
