Fine Bubble Disc Diffuser

Fine Bubble Disc Diffuser

Fine bubble disc diffusers are designed to release small air bubbles from the bottom of wastewater treatment tanks. These bubbles help transfer oxygen into the water efficiently, creating the ideal conditions for biological treatment. By supporting the growth of beneficial bacteria, fine bubble disc diffusers play a key role in breaking down pollutants.

These disc diffusers work by forcing air through precision-made micro pores in a flexible membrane. As the air escapes, it forms thousands of fine bubbles with a large surface area. This increased surface area improves the oxygen transfer rate, making the system more energy-efficient and effective in supporting biological activity during sewage treatment.

At Bioflow Industries Pvt. Ltd., we manufacture and supply high-performance fine bubble disc diffusers for wastewater treatment plants. Our diffusers are engineered with durable materials, advanced technology, and tested designs to ensure long life and low maintenance. We offer various sizes, and both diameter and length can be customized as per client requirements. Our disc diffusers are easy to install and deliver consistent performance across different operating conditions.

Lengths and diameters can also be customized as per customer’s requirement.
