Director I™ Floating Baffles
Dramatically improve wastewater treatment lagoon efficiency with the Director I Floating Baffle System.
Without Baffles Short Circuit
With Baffles Divert Flow
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.
CUSTOM BUILT FOR YOUR LAGOON
Every Director I Floating Baffle is manufactured to fit your specific lagoon profile. Our exclusive fully encapsulated bottom anchor creates an undivided seal along the bottom of the lagoon to prevent short circuiting and protect your liner.
Materials To Match Your Application
Environetics, Inc. is not limited to fabricating from one material but uses a variety of materials including Hypalon®, X-R 5®, or PVC. We will assist you in choosing the best fabric for your site and the length of service desired. The selection of a geomembrane fabric resistant to the chemical composition of the waste water is of critical importance.
Environetics will assist you in making the proper fabric choice using these guidelines:
- Chemical composition of the waste water
- Exposure to ultra violet light
- Temperature range
- Hydraulic flows
- Wind forces
- Temporary or long term forces
The Director I Floating Baffle System is a cost effective upgrade for new and existing lagoons. Floating Baffles install quickly and easily and require little or no maintenance throughout their 20 year life cycle. Installation can be completed in less than a day without costly equipment or expensive labor.
