1.How do disc diffusers work, and what are some of the benefits of disc diffuser aeration systems?
Disc Type Air Diffuser, especially 9-inch fine bubble disc diffusers, are extremely common in the wastewater treatment industry. They typically consist of disc-shaped ceramic, plastic or EPDM rubber membranes attached to a system of pipes and blowers. The blowers send air through the pipes, and the air flows out in bubbles through tiny slits or pores in the diffuser membranes. The bubbles then aerate the wastewater by transferring oxygen to the water column.
Disc Type Air Diffuser may have additional protective coatings such as PTFE, FEPDMTM or Viton® coatings to help protect against fouling.
2.Some of the advantages of Disc Type Air Diffuser include the following:
-
Improved design: Because they are so slender, many Disc Type Air Diffuser can fit into a tank with a relatively modest footprint.
-
Increased mixing capabilities: Many tube diffusers tend to produce relatively large bubbles. The large bubbles often produced with tube diffusers offer superior mixing capabilities.
-
Lower cost: Tube diffusers are an excellent option for cost-conscious consumers. Reduced stainless steel use is a large part of the reason - stainless steel is expensive, whereas plastic and rubber are more economical.
-
Neutral buoyancy: Tube diffusers are neutrally buoyant. This characteristic gives them an advantage in certain aerator layouts.
-
Reduced labor time: The reduced quantity of stainless steel needed for tube diffusers leads to reduced labor time and quicker delivery of tube diffuser grids. This feature makes tube diffusers an attractive option when a quick turnaround time from design to installation is essential.
