Description

SSI ECD215 Disc Diffuser System – Advanced Aeration for Biological Wastewater Treatment

The fine bubble disc diffuser is a highly efficient aeration device widely used in wastewater treatment processes, particularly in aerobic biological treatment systems. It disperses air through fine pores, generating a large number of microbubbles to enhance oxygen transfer efficiency and effectively increase dissolved oxygen (DO) levels in water. This type of diffuser is commonly applied in aeration tanks, oxidation ditches, and aerobic treatment systems in wastewater treatment plants.

Working Principle of Fine Bubble Disc Diffusers

The fine bubble disc diffuser operates by forcing compressed air through a microporous diffusion disc, creating a dense cloud of fine bubbles. As these bubbles rise through the water, they facilitate gas-liquid contact, allowing oxygen to dissolve into the wastewater and increasing its DO concentration. Due to their small size (typically 1–3 mm in diameter), these bubbles provide a significantly larger surface area compared to coarse bubbles, maximizing oxygen transfer efficiency.

Key Advantages:

High Oxygen Transfer Efficiency (OTE): Microbubbles enhance mass transfer, reducing energy consumption.

Uniform Aeration Distribution: Ensures consistent DO levels throughout the tank.

Durable & Clog-Resistant: Advanced membrane materials minimize fouling and extend service life.

This technology is essential for energy-efficient and high-performance biological wastewater treatment.
