Wastewater Treatment System Product: CEN 7


Designed to treat up to 700 gallons per day of domestic strength wastewater.

The one-tank CEN7 model is the company’s mid-size residential system for enhanced nitrogen removal in nutrient sensitive areas. Certified to NSF/ANSI 40/245 standards, this exceptionally small footprint system has demonstrated best-in-class nitrogen removal performance in multiple-state field testing protocols.

The CEN7 is a rugged, compact, one-tank workhorse. Featuring a footprint of only 8′-2” x 4′-8″, this system is rated to treat domestic strength wastewater flows of 700-gallons per day to NSF 40/245 standards making it a logical choice for septic professionals designing systems for mid-sized homes in tight, environmentally sensitive locations where maximum nitrogen reduction is required or desired.

Weighing only 705 pounds, this durable, hand-laid fibre-reinforced plastic (FRP) unit can be squeezed into tight and difficult sites. Designed to accommodate variable flows and shock loadings as well as being highly energy efficient (1.7 kWh/day), this low maintenance system, like the other CEN residential models, is ideally suited for both replacement sites and new construction.
