Lee Mechanical installed the first SAGR unit in Wisconsin.  This SAGR unit is located at Birchwood Foods in Kenosha. SAGR (submerged attached growth reactor)  is a wastewater treatment program that provides ammonia removal from wastewater in cold climates.

Functions of a Submerged Attached Growth Reactor (SAGR) system:

• Provides biological treatment for wastewater by promoting the growth of beneficial microorganisms on submerged media.
• Removes nutrients such as nitrogen and phosphorus from wastewater, helping to reduce water pollution.
• Lowers Biological Oxygen Demand (BOD) by breaking down organic matter in the wastewater.
• Ensures efficient oxygen transfer to the microorganisms, enhancing their ability to degrade pollutants.
• Operates effectively in cold climates, maintaining treatment efficiency even in low temperatures.
• Minimizes odors associated with wastewater treatment processes.
• Requires a relatively small physical footprint, making it suitable for areas with limited space.
• Produces high-quality effluent that can meet stringent discharge standards or be reused for various purposes.
