DISK DIFFUSER – WASTEWATER TREATMENT

PRODUCT DESCRIPTION**

A Disk Diffuser is a high-efficiency fine-bubble aeration device used in STP, ETP, and industrial wastewater treatment systems. It delivers uniform air distribution through micro-perforated EPDM or silicone membranes, ensuring maximum oxygen transfer efficiency (OTE) for biological treatment processes.

Designed for long-term durability, low energy consumption, and stable performance, disk diffusers are widely used in aerobic tanks, MBBR systems, SBR tanks, equalization basins, and nitrification processes.

Key Features

• Fine-bubble aeration for high oxygen transfer efficiency

• EPDM/Silicone membrane with precision perforations

• Corrosion-resistant PP/ABS diffuser body

• Low-pressure loss and high airflow capacity

• Check valve integrated to prevent backflow

• Easy installation on SS/UPVC/Mild Steel air grids

• Suitable for continuous and intermittent aeration

Advantages

• Improves BOD/COD reduction

• Reduces energy consumption of blowers

• Long service life with minimal maintenance

• Uniform bubble distribution across the tank

• Designed to resist fouling, chemical attack, and tearing

Applications

• Sewage Treatment Plants (STP)

• Effluent Treatment Plants (ETP)

• Industrial wastewater treatment

• Aeration tanks, MBBR reactors, SBR basins

• Aquaculture & aerobic bio-filtration systems

Sizes Available

Disk diffusers are commonly available in the following sizes:

• 9″ (225 mm) – Standard for compact systems

• 12″ (300 mm) – Higher output for large aeration tanks
