SSI Satellite™ Fine Bubble Disc Diffuser

Aeration can account for 50–70% of a wastewater treatment facility's total energy consumption. The SSI Satellite™ was developed to help facilities reduce aeration air demand by maintaining strong oxygen transfer performance at low airflow rates.  

Designed for operation between approximately 0.3 and 0.75 SCFM per diffuser, the Satellite supports low-flux aeration strategies that can reduce blower output requirements and improve overall system efficiency. 

Oxygen transfer efficiency is not fixed. As airflow rates decrease, fine bubble diffusers can produce smaller and more uniform bubbles, increasing the surface area available for oxygen transfer. 

The challenge is that most fine bubble disc diffusers are designed to operate at much higher airflow rates. When operated well below their intended design range, performance can become less predictable and efficiency gains may be reduced. 

The SSI Satellite™ was engineered specifically for low-flux operation. Optimized for approximately 0.3–0.75 SCFM per diffuser, it helps maintain efficient oxygen transfer in applications where conventional diffuser designs may not be operating in their ideal range. 

The SSI Satellite diffuser is designed to support wire-to-water aeration optimization by reducing airflow demand while maintaining high oxygen transfer efficiency. Lower airflow requirements can reduce blower power consumption, improve overall aeration system efficiency, and lower lifecycle operating costs. When combined with high-efficiency blower packages, dissolved oxygen control systems, and advanced process optimization strategies, the Satellite can become part of a complete energy-efficient aeration solution 

The SSI Satellite delivers maximum benefit in wastewater treatment applications where energy efficiency, reduced operating costs, and long-term performance optimization are primary design considerations 

Energy Optimization Projects 

Facilities evaluating ways to reduce blower energy consumption and  improve aeration efficiency can leverage the Satellite's low-flux design to reduce air demand while maintaining oxygen transfer performance 

High-Return Upgrade Opportunities 

Projects with significant blower energy consumption, high electrical costs, or strong lifecycle cost objectives often present the greatest opportunity for energy savings and attractive payback periods. The Satellite is particularly well-suited when facilities are evaluating long-term operating cost reductions alongside capital investments 

ESCO and Retrofit Projects 

The Satellite can support aeration system upgrades implemented through planned replacement programs, energy performance contracts, or targeted retrofit projects. Facilities pursuing energy reduction goals may find value in evaluating the Satellite even outside of traditional replacement cycles when projected savings support the investment. 

Every wastewater treatment facility has unique airflow requirements, energy costs, and process objectives.

SSI Engineering can evaluate your existing aeration system and identify opportunities to reduce blower energy, improve oxygen transfer performance, and lower total lifecycle costs through optimized diffuser design.
