Adenus® systems are comprised of an effluent collection system, secondary treatment plant, and drip dispersal. The tank in your yard settles the waste stream into three distinct layers during primary treatment:
• Scum • Effluent • Sludge
The effluent filter ensures that only the effluent is collected from the tank and sent to the plant for processing. As the scum accumulates, it transforms into sludge and settles. The sludge is mostly consumed by the micro-organisms present in the tank.
