The problem

A tequila distillery wastewater treatment plant in Mexico was struggling with severe organic loading from raw vinaza, the high-strength wastewater byproduct of agave fermentation and tequila production. The aeration tank had lost significant treatment capacity to heavy sludge accumulation and a thick surface scum layer that restricted oxygen transfer and biological activity, while persistent odors indicated anaerobic conditions and incomplete organic degradation. The plant needed a high-CFU industrial wastewater bioaugmentation program capable of digesting the accumulated organic load and restoring aeration capacity without major capital investment in the existing treatment system.

Before, during, and after

Before
Before bioaugmentation, the tequila vinaza wastewater treatment plant was experiencing severe operational constraints driven by extreme organic loading from agave fermentation residues. The aeration tank showed dramatically reduced treatment capacity from heavy sludge accumulation at the tank bottom and a thick scum layer at the surface that restricted oxygen transfer and biological activity. Persistent odors indicated incomplete organic degradation across the plant, and rising aeration demand drove electricity costs higher even as effluent quality continued to fall.

After
Following continuous application of Wastewater Treat (WT), a high-CFU industrial wastewater bacteria blend, offensive odors were fully eliminated within seven days of treatment. Within fourteen days, the heavy surface scum layer was almost completely removed, restoring effective oxygen transfer in the aeration tank. Continued biological activity digested more than one meter of accumulated sludge at the tank bottom, evidenced by a corresponding drop of over one meter in aeration tank water level. As sludge volume decreased, treatment capacity recovered and electricity consumption fell as aeration demand dropped. For tequila distilleries, agave processing facilities, and industrial wastewater plants handling high-strength fermentation byproducts, this case demonstrates what high-CFU bioaugmentation can deliver on sludge digestion, odor elimination, and aeration recovery under real distillery operating conditions.
