SSI Aeration Private Limited

• 20 (M3/H) Coarse Band Diffusers are aeration devices used in wastewater treatment and industrial applications to introduce air into liquids. They generate large air bubbles (typically greater than 6 mm in diameter) to enhance oxygen transfer and mixing.
• Our Wide Band diffusers are available in 304L or 316L stainless steel. Made with cast end caps welded all around, deflectors are supplied with each diffuser but can be removed. The coarse bubble diffuser is intended to be a clog-free design, with oxygen transfer rates of 0.5 to 0.8% per foot of submergence (1.7 to 2.5% SOTE/m).
• A reliable alpha value coupled with an economical design to cover the tank floor make this diffuser the ideal choice for mixing in aerobic digesters, channels, equalization tanks and grit chambers.

Specifications:

• Design Flow: 10-40 SCFM (17-67 Nm/hr)
• Flow Range: 0-40 SCFM (0-67 Nm/hr)
• Hole Quantity: 44

• Bubble Size: Larger bubbles (6–50 mm) compared to fine bubble diffusers.
• Oxygen Transfer Efficiency: Lower than fine bubble diffusers but provides strong mixing.
• Material: Made from durable materials such as PVC, EPDM, or stainless steel.
• Applications: Used in aerobic wastewater treatment, sludge digestion, and equalization tanks.

• 10 M3/H Coarse Cap Diffusers are aeration devices used in wastewater treatment and industrial applications to introduce air into liquids. They generate large air bubbles (typically greater than 6 mm in diameter) to enhance oxygen transfer and mixing.
• Coarse Cap Diffusers are most commonly used in aerobic digesters and equalization tanks where high rate oxygen transfer efficiency is not required. They are manufactured from black Acrylic plastic containing UV protection and membranes are made from the same EPDM compound that SSI uses in fine bubble disc diffusers. SSI Coarse Cap diffusers have a MNPT thread.

Specifications:

• Design Flow: 3-6 SCFM (7-10 Nm/hr)
• Flow Range: 0-10 SCFM (0-17 Nm/hr)
• Slit Quantity: 10 x 5mm  holes
