Clarifier design and operation is essential to enhanced biological phosphorus removal. Under anaerobic conditions within a deep sludge blanket, biomass releases soluble phosphorus that affects the final effluent quality.The Evoqua clarifier design, which features the FEDWA baffle system and Tow-Bro Unitube Hydraulic Header, limits the release of phosphorous from settled sludge.The FEDWA energy-dissipating inlet reduces flow velocities and improves flocculation for more efficient solids settling. The Tow-Bro unitube header quickly and effectively removes settled solids with minimal disturbance of the sludge blanket. The net result is a low sludge blanket and low sludge retention time in the clarifier, both of
