Since 1998, U.S. Water’s Process Technologies team has supported the fuel ethanol industry with innovative chemistries designed to reduce air pollution, prevent deposits, prevent corrosion, and enhance fermentation and corn oil recovery, in order to improve fuel ethanol manufacturer profitability. U.S. Water’s flexible approach to remotely monitoring and analyzing operational data brings additional value to plant operations, as operators are engaged with U.S. Water 24/7 to mitigate risks that could lead to unexpected downtime.

Key Biofuels Chemistries

CorrPro is a family of final product corrosion inhibitors with enhanced corrosion, handling and pHe buffering properties. 

Developed specifically for the biofuels industry, pHytOUT is a liquid deposit control inhibitor that is typically added to the fermenters during propagator preparation. This easy to feed chemistry can reduce an ethanol plant’s dependency upon sulfuric acid while providing an overall process fouling inhibitor package. 

VOxOUT 70C is a “fermentation friendly” CO2 scrubber chemical additive treatment designed to enable a plant’s ability to meet Hazardous Air Pollutants (HAPs) when unable to meet compliance via mechanical scrubbing alone. VOxOUT 70C replaces the sodium bisulfite with ammonium bisulfite and a proprietary catalyst that results in a quicker and more complete conversion of the acetaldehyde resulting in significantly lower bisulfites being sent to fermentation.

As many ethanol producers are investing in corn oil recovery (COR) equipment platforms, COR additives are found to be a cost-efficient means of aiding mechanical separation/recovery and increasing overall COR yield.  The portfolio of COR line of corn oil recovery products is designed to provide the right product for the plant-specific COR platform and operating conditions.  The products are easy-to-feed liquids available in either tote or bulk delivery quantities and come with a self-contained chemical metering skid.

The ProHib product line is comprised of scale inhibitors designed to prevent deposit formation in evaporators across a broad spectrum of foulants - including Oxalates, Carbonates, and Magnesium Phosphate deposits. Upon plant operating data review by EPT personnel, ProHib recommendations are based on a firm understanding of the fouling tendencies specific to each facility. 

U. S. Water has a complete line of Food Grade antifoams acceptable for use in Fuel Ethanol production.

Yeast health suffers when bacterial infections consume sugar meant to feed yeast and generate organic acids that stress yeast. Unhealthy yeast results in a decreased ethanol yield. U. S. Water provides two popular antibiotics, penicillin and virginiamycin, with full technical support and competitive pricing.
