Slurry & Manure
22,000-head beef feedlot clears crust and sludge across its lagoon system with MICROBE-LIFT®/DFP.
Cattle ranch feedlot, 22,000 head · Veracruz, Mexico · 22 October 2026
The challenge
Twelve of the 16 lagoons were saturated. Each had a surface crust and heavy sludge on the bottom, odour was significant, and management were concerned that effluent was polluting the river and neighbouring land.
The approach
Ecological Laboratories designed a MICROBE-LIFT®/DFP programme with a set dose for each lagoon, aimed at removing crust and sludge and getting the waste flowing through the pits and lagoons.
Results
Reduced
Surface and bottom solids
Largely removed
Lagoon crust
Reduced
Odour
Met discharge parameters
Effluent
Before-and-after photographs across the lagoons show the crust almost completely removed, and cleaner effluent reaching the river. Ecological Laboratories report that every objective was met: less surface and bottom solids, less odour, better flow through the system, and effluent quality that met its limits. The study is mainly photographic rather than measured, which is how we describe it.
