US Water designs ethanol filter to remove potential sulfate

September 12, 2014 |

In Minnesota, U.S. Water has introduced an ethanol filter designed to remove sulfate from final ethanol products, as well as to address color, turbidity, acidity, pHe, chloride and iron. Unlike other filters on the market, US Water’s product eliminates both existent and potential sulfate, reducing sulfate at the manufacturing site as well as the ability for it to manifest at delivery.

The new bolt-on, mechanical/chemical system addresses the materialization of potential sulfate can cause a product that initially met existent sulfate specification levels to exceed the maximum permissible level of 4ppm at time of delivery. The new filter can help producers ensure compliance with quality assurance standards, or used as a mobile unit, it can be deployed to bring off-spec ethanol back into alignment.
