Model CEN21


Building near the coast or waterways?  Concerned about possible issues with wastewater?  We have the solution.

Nitrogen Reduction: Designed to reduce total nitrogen (TN) to single digit levels, our CEN units are THE solution for water sensitive areas.  Our units are the gold standard in advanced wastewater treatment.

Scalable: Specifically designed for phased installation, the CEN21 is the perfect solution for developers wanting to integrate wastewater management within the buildout plan.

Customizable: Can be tailored to meet the unique needs of residential, mixed-use & commercial development.  Ideal for sites that demand high seasonal flows, such as campgrounds, resorts, and shopping centers.  

Mighty: A very small footprint (15’3” x 6’7”) and weight of just over 1500 pounds makes this system highly maneuverable and adaptable to the very tightest and most difficult sites.

Manageable: Like all of our units the CEN21 can be placed using standard construction equipment.
