ASG and GDM: A Powerful Duo
Aerobic Granular Sludge (AGS)
What is it?
AGS is a biological process that utilizes specialized bacteria to treat wastewater. These bacteria form tiny, dense granules that can settle quickly, making them ideal for efficient wastewater treatment.
How does it work?
The AGS process involves creating a specific environment where these granules can thrive. Oxygen is continuously supplied to the wastewater, promoting the growth of aerobic bacteria. These bacteria consume organic matter in the wastewater, breaking it down into simpler compounds.

How AGS and GDM Work Together
The combination of AGS and GDM creates a highly effective wastewater treatment system.
Wastewater Treatment:
The AGS process breaks down organic matter in the wastewater using aerobic bacteria.
Solids Separation:
The treated wastewater from the AGS process is then passed through the GDM system. The membranes filter out any remaining solids, producing a high-quality effluent. Lastly, Ultraviolet light is used as a UV Disinfectant to produce clean water for non-potable reuse applications such as irrigation, horticulture, and industry.
Enhanced Efficiency:
The combination of these two technologies offers several advantages:
- Reduced Sludge: The AGS process produces 60+% less sludge compared to traditional wastewater treatment methods.
- Lower Energy Consumption The AGS process produces 60+% less sludge compared to traditional wastewater treatment methods.
- Improved Water Quality: The AGS process produces 60+% less sludge compared to traditional wastewater treatment methods.
By working together, AGS and GDM provide a sustainable and efficient solution for wastewater treatment, offering a valuable resource for communities and industries alike.
