Project Summary
Solution
Based on the project specifications, a Biogas Floating cover with a positive pressure design was chosen and installed. These types of covers are increasingly popular with Food processors, integrated growers, and intensive livestock producers as a viable treatment method for agricultural wastewater treatment.
In addition, these digesters provide an essential sustainable solution for reducing carbon in our environment. The methane these digesters produce is an important alternative energy source and can produce biomethane fuels and electricity generation for utilities, producers, and consumers.
Installation
After completing the double liner system, the lagoons were filled, and an 80 mil (2.00 mm) HDPE cover was welded in sections on-site and then floated into place. Testing of the agricultural wastewater liner systems included using Layfield’s Vacuum Acoustic Leak Identification method (VALID), developed explicitly for double-lined systems. The VALID system simultaneously tests the primary and secondary liners using a single survey. Layfield also manufactured the geomembrane and geonet products utilized.
