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.
