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%. 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. 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. system consists of four cells separated byIn the first reactor cell, intense aeration generates enough oxygen to convert the influent CBOD to carbon dioxide and biomass while maintaining solids in suspension.

Floating Lagoon Baffle Curtains increase retention times in lagoons or settling basins, eliminate dead zones, and create a desired flow pattern. 

When used for water treatment, Floating Lagoon Baffle Curtains will provide your facility with an efficient and effective way to treat your entire lagoon.  MPC will fabricate your Floating Lagoon Baffle Curtain to meet your specific requirements of length, depth, and material. Download our Floating Baffle Engineer Specification or tell us what you are looking for to get a specific estimate.  MPC Containment can handle your most complex design.The basic goals in designing the bio-separator were: The Bio-Separator is a pre-engineered, custom fabricated, flow diverting baffle. It can be manufactured using a variety of fabric reinforced coated materials. The material selection is based on the application and the chemical make-up of the waste to be treated. The Bio-Separator is fabricated to the specific length, depth, and side slope desired. Windows can be positioned to achieve the desired flow pattern in the lagoon. The use of the Bio-Separator offers an economical approach for the upgrade of existing lagoon systems.

The Bio-Separator meets the allowable limits for BODs and Total Suspended Solids imposed by the United States Environmental Protection Agency. The floating baffles allow the system to be upgraded without the expense and difficulty of dewatering the lagoon; which is usually required when earthen dikes or rigid baffle systems are used. Lagoon systems using the floating baffles provide a low cost alternative to activated sludge systems. When properly designed, these systems can produce effluents in which the average concentration for BODs and Total Suspended Solids meet the requirements set by the EPA. These systems have attractive features, which include very little maintenance or operator attention, construction at a cost 40-50% less than activated sludge systems, and operating at a power level 50% less than activated sludge plants. Industrial lagoons: The Bio-Separator can be designed and fabricated to meet the specific needs of an industrial waste treatment process. A fabric resistant to the waste can be selected based on bench scale treat ability studies.

A curtain can be used to create mixing areas, activate sludge basins, clarify areas with positive sludge return, and disinfect areas. Floating baffle curtains offer an economical approach for the upgrade of existing lagoon systems and a cost-effective method of flow diversion in new lagoon systems. The floating baffles allow existing systems to be upgraded without the expense and difficulty of dewatering the lagoon. All floating baffles are pre-engineered, and custom fabricated to the specific length, depth, and side slope for each installation. Flow-through windows are sized and positioned within the baffle to achieve the desired flow pattern in the lagoon. The baffle can be manufactured using a variety of fabric reinforced coated materials depending on the application and the chemical make-up of the waste to be treated, as well as the weather characteristics at the installation site. The material most commonly used is XR-5, a polymer coated polyester. Other materials available are Hypalon and Polypropylene.

The curtain is weighted with a galvanized chain dielectrically sealed into the ballast collar at the bottom of the baffle. A foam log is sealed into the floatation collar. Dividing a cell with flow diversion baffles restores the cells full design hydraulic retention time by preventing retention time lost due to short-circuiting. Reaction kinetics in the ponds are improved by dividing a single cell into multiple cells operated in series. The baffles can also be used to isolate a quiescent settling zone in the lagoon system or to introduce a complete mix zone to increase the CBOD removal capacity of a lagoon system that is short on retention time. curtains are manufactured in factory settings designed to increase retention times, eliminate dead zones, improve flow patterns and mixing in circular or rectangular tanks.  The Baffle curtains offer existing tanks an option for retrofiting to current issues relating to regulation or poor water quality.  Baffle curtains are an economical choice for new systems as well. 

ECA provides a low maintenance alternative to CMU, fiberglass, or steel wall structure.  The baffles can be modified as well or taken down for maintenance or relocated.  ECA can provide baffle solutions that achieve .3 to .7 baffle factor in tanks or reservoirs.  Baffle curtains are flexible and can be handled into tanks with minimal equipment or through narrow entry ways.  There are several designs available to offer solutions with anchoring or securing to existing ceilings,walls or floors without impacting the baffle performances.  The baffle systems install quickly and easily with prefabricated hardware kits.  ECA has offered solutions to increase water quality for existing clearwells, steel and bolted steel tanks, redwood, and uncovered/covered reservoirs. are pre-engineered and custom fabricated to offer an economical approach for the upgrade of existing lagoon systems and a cost-effective method of flow movement in new lagoon systems. Flow-through windows can be positioned anywhere within the baffle to achieve the desired flow pattern in the lagoon.
