Next Generation Anaerobic Digestion Technology Selection and Treatability Testing

Geosyntec was retained by a confidential client to perform an alternatives evaluation for the treatment of process wastewater at their rum distillery located in the Caribbean (the Site). The existing Anaerobic Filter (AF) reactors at the Site need replacement due to their high maintenance costs and frequent media replacement. Our client was looking for the most costeffective and technologically advanced replacement technology to manage their wastewater. After reviewing and discussing proposed solutions with our client and reaching out to several technology providers/vendors, as well as evaluating cost and non-cost criteria, the project team agreed upon the best technical solution and vendor for the facility. However, to confirm the design COD loading rate, process performance and stability, robustness after down time, and to optimize operating costs, the selected vendor performed laboratory testing on the Site wastewater with technical oversight from Geosyntec.
