  • NEFCO density current Baffle design

    The study was originally conceived to evaluate the performance of the NEFCO Stamford Baffle design and several variations on that design to better understand the parameters that affected baffle performance. To that end, the plan was straightforward. The first step was the simulation of a 70-ft diameter clarifier. This clarifier would serve as the test bed to calculate the predicted effectiveness ...

  • NEFCO™ Awarded new patents case study

    NEFCO™ has been granted two new patents for its Dual Surface Baffle System. The Dual Surface Baffle was developed from work done as a part of NEFCO’s on-going Computational Fluid Dynamics (CFD) Density Current Baffle Study. The first, US Patent No. 7,556,157, describes a Dual Surface Baffle with a curved lower baffle segment. The second, US Patent No. 7,726,494, describes a Dual ...

  • The Monclova experience case study

    The Town of Monclova, Mexico found it necessary to increase the hydraulic capacity of its municipal wastewater treatment plant by 35% – from approximately 11.5 MGD to 15.5 MGD. The increase in flow was accomplished by upgrading the plant’s biological treatment process. Once the modifications were completed, the flow through the plant was gradually increased. As the increased flow ...

  • NEFCO, incorporated case history

    In mid-2007, the wastewater treatment plant in Monclova Mexico was faced with a dilemma. The City had just upgraded their biological treatment scheme to increase flow through their plant by 35%, from approximately 11.5 mgd to15.5 mgd. They needed to add either a fourth secondary clarifier to keep within they discharge limits of 10 ppm TSS, or improve the operation of their three existing ...
