Dramatically improve wastewater treatment lagoon efficiency with the Director I Floating Baffle System.
Flow diversion curtains increase hydraulic retention time (HTR) and can increase the effective treatment area of a lagoon from less than 20% to over 95%. Floating baffles create hydraulic flow patterns that guide wastewater through a serpentine route from the inlet to the outlet, improving aeration and allowing contaminants and solids to settle. The extended treatment time significantly reduces Biological Oxygen Demand (BOD) and Total Suspended Solids (TSS).

Floating baffle curtains separate reactor cells from settling cells to create a dual-power, multicellular (DPMC) aerated lagoon system, allowing aerators to operate more efficiently to dramatically reduce energy costs. The DPMC system consists of four cells separated by baffles. In the first reactor cell, intense aeration generates enough oxygen to convert the influent CBOD to carbon dioxide and biomass while maintaining solids in suspension. The following three settling cells provide sedimentation, solids stabilization, and sludge storage. The settling cells use less aeration to allow solids to settle while supporting a thin aerobic layer at the top of the solids deposit to inhibit algal growth. A properly designed dual-power, multicellular (DPMC) aerated lagoon system using floating baffle curtains uses 50% less power than a comparable Activated Sludge system.
