Aquasust Diffuser Materials
1. Exxon molecular weight bimodal distribution EPDM
To make EPDM diaphragms have high elasticity and good tear resistance, we use molecular weight "bimodal"
distribution of EPDM, molecular weight "bimodal" distribution of EPDM both high molecular weight polymer mechanical
properties and low molecular weight polymer processing properties of EPDM, the molecular weight "bimodal" distribution of EPDM has both high molecular weight polymer mechanical properties and low molecular weight polymer processing properties of EPDM. EPDM with molecular weight "bimodal" distribution
2. DMS Controlled Long Chain Branched Technology EPDM
DSM's controlled long-chain branching technology, EPDM, balances the properties of polymers by simultaneously
achieving long-chain branching and a narrow relative mass distribution. The main feature is that higher vulcanization
rates increase the degree of cross-linking, and the higher the degree of cross-linking, the better the resilience.
3. IIR268 Butyl Rubber
Butyl rubber molecular structure of the short double bond and the side chain methyl dispersion density is larger, so it has
excellent tear resistance. A small amount can greatly improve EPDM's tearing and tensile deformation properties.

Plugging Holes: A Chemical Phenomenon, Not a Physical One
Causes of Plugging
Organic solvents in the sewage water extract hydrophilic zinc salts and accelerators from the rubber formulation.
Plugging phenomenon
Hydrophilic zinc salts combine with calcium and magnesium ions in the water in the presence of oxygen.
Results of Plugging
Due to the same electrical properties, solid dirt particles agglomerate and scale on the inner surface of the membrane pore, resulting in clogging.

FavoritesHow to Choose the Right Aeration Product for You
Microporous Disc diffuser is a key component of the aeration system of wastewater treatment, which directly affects the dissolution efficiency of oxygen, energy consumption, and later maintenance costs. When comparing the diameter of 350mm, 260mm, and 215mm microporous aeration disk, can be from the performance, installation, maintenance, and other aspects of comprehensive consideration:
Disc diffuser performance
Oxygen transfer efficiency: 350,270 diameter larger aeration disk due to the large surface area, theoretically can produce more bubbles, improve the efficiency of oxygen dissolution. However, the actual oxygen transfer efficiency also depends on the size and distribution of the bubbles, as well as the depth of aeration. Smaller aeration disks may be more likely to produce fine bubbles, helping to improve oxygen transfer efficiency.
Coverage: Larger diameter aeration disks are able to cover a larger area, which means that a smaller number of disks may be required for the same treatment capacity.
Installation
Layout Flexibility: 215 Smaller aeration trays provide greater layout flexibility in aerobic tanks, easier to adapt to the shape and size of the tank, and facilitate more even oxygen distribution. 270,350 Larger-sized trays simplify layout design by reducing the number of trays required due to their wide coverage area. This is advantageous for large aerobic basins as it reduces installation complexity and lowers initial investment costs. However, this may be at the expense of layout flexibility to some extent.
Installation costs: Larger diameter aeration trays may reduce the total number of trays required, reducing the number of mounting points and thus the initial installation costs to some extent. However, this may also mean that a stronger support structure is required.

Maintenance
Clogging Risk: All microporous aeration trays can face clogging problems, but smaller size 215 trays may require more effort to inspect and clean due to the larger number of trays. However, it may be easier to maintain individual smaller 215 trays, especially if they need to be replaced.
Maintenance Costs: In the long run, maintenance costs depend not only on the durability of the trays themselves but also on their resistance to clogging and ease of cleaning. The smaller 270,215 discs may offer more flexible maintenance and replacement options.
Maintenance Costs: In the long run, maintenance costs depend not only on the durability of the trays themselves but also on their resistance to clogging and ease of cleaning. The smaller 270,215 discs may offer more flexible maintenance and replacement options.
Layout and Design
270mm and 215mm: The smaller size aeration trays offer greater layout flexibility and are better suited to irregularly shaped or smaller aerobic tanks. They enable more even oxygen distribution but may require more installation points and initial investment.
Operation
Energy consumption: 350 Large-size aeration trays may reduce the required fan power to some extent due to the large area covered, thus reducing energy consumption. However, this also depends on the actual oxygen transfer efficiency and system design.
Cleaning and Maintenance
Clogging and Cleaning: 215 Smaller-sized aeration trays may increase maintenance and cleaning efforts due to the large number of trays, especially if the effluent contains large amounts of suspended solids or fibrous material. However, individual aeration disks may be easier and less costly to replace or maintain.
Replacement Costs: 270,350 Replacement costs for larger-sized aeration disks may be higher, especially if replacement is required, but overall maintenance may be less frequent. Smaller-sized aeration disks, while less costly individually, may cost more overall if they are replaced frequently.
Replacement Costs: 270,350 Replacement costs for larger-sized aeration disks may be higher, especially if replacement is required, but overall maintenance may be less frequent. Smaller-sized aeration disks, while less costly individually, may cost more overall if they are replaced frequently.
Comprehensive Considerations
For large-scale domestic wastewater treatment plants, a larger diameter 270,350 aeration disk may be preferred to minimize the number of installations and initial investment.
Where oxygen transfer efficiency is more important, or for aerobic tanks with more complex spatial layouts, smaller 215 aeration trays may be a better choice because they provide more uniform oxygen distribution and higher oxygen transfer efficiency.
Maintenance and operating costs are also selection considerations, and 215 smaller aeration discs may be superior in terms of replacement cost and flexibility, although they may require more labor during maintenance.
The final selection should be based on the design requirements, operating budget, and maintenance strategy of the specific WWTP, and usually involves a trade-off between performance, cost, and ease of operation.
