Our CEN advanced wastewater treatment system (certified NSF 40/245) is an enhanced denitrification system allowing single digit TN, BOD, and TSS.  The CEN units achieve a total nitrogen removal rate of 75% in NSF testing.

The CE system (NSF 40) exceeds the industry standard with 10-20 mg/L TN, BOD, TSS.

With an integrated, inclusive septic tank and small footprint, the lightweight, fiber-reinforced plastic system fits tight, difficult-to-access sites. Contact-filtration treatment includes aerobic and anaerobic chambers with built-in flow equalization, continuous recirculation and controlled discharge.

We offer residential units from 1-8 bedrooms and commercial units with capacities of 1,000 gpd to a scalable 6,000 gpd unit.
