Background: Brooks Lake Lodge, Wyoming, operates a two-cell lagoon for its wastewater. This lagoon is designed to treat 0.007 MGD wastewater from its guests and employees. The treatment plant did perform well during the summer months with the original aeration system but currently does not have enough oxygen in the warmer months. During the winter months, there is too much ice on the surface of the lagoons and the temperature of the wastewater is so low that there is little or no biological activity in the lagoon. The lodge has been looking for a solution to improve summer and winter wastewater treatment to reduce effluent BOD and TSS in order to meet its discharge limit.

Upgrading to Bio-Shells: Brooks Lake Lodge’s engineer had long recommended placing insulated covers over the lagoons and adding additional treatment by fixed-film. WCS’ patented Bio-Shells were chosen over other competitive options. It is based on its proven performance in cold weather, low capital and operating costs, and energy efficiency.

WCS completed the installation of Bio-Shells and two baffle curtains in November 2017. WCS team will be onsite to place the stored floating cover into the pond, and verify everything is operating functionally in the spring of 2018. The Brooks Lake Lodge minimized its capital investment costs for the lagoon’s upgrade by choosing Bio-Shells, and will continue to enjoy monthly operating savings due to lower maintenance costs and energy savings compared to alternative solutions. WCS also offers protection to its customers by providing a product warranty that includes a performance guarantee.

 

Key Benefits of the Bio-Shell®:

 

  1. A Bio-Shell® system represents the least expensive treatment upgrade available in terms of both capital expense as well as O&M expense.
  2. An upgrade utilizing Bio-Shells will not require new operators with additional training, certification, and or a higher pay grade.
  3. The Bio-Shell® system is intended to be a modular, expandable, system that is capable of growing with the facility over the next 20+ years.
  4. The Bio-Shell® system can be coupled with other, more conventional, technologies to address future Phosphorous or Total Nitrogen limits.
  5. Because of energy efficiency, the Bio-Shell® system can be considered “green” and will aid in qualifying the facility for Energy Efficiency grants if any are available through utility providers.
