White Paper - METHANOL INSTITUTE

United States practice nitrification (oxidation of ammonia to nitrites and nitrates), but only about 5 percent of Nr is removed through engineered denitrification treatment systems. A nitrogen removal system presents a method for removing a large portion of the nitrogen concentration from wastewater effluent before it is discharged.

Use of Treated Effluent Water in Cellulosic Ethanol Product...

Current water consumption rates in corn dry grind ethanol plants are 3 to 4 gallons of water per gallon of ethanol produced (gal/gal) and 6 to 10 gal/gal for cellulosic ethanol plants. The research team's main goal was to examine the use of treated wastewater effluent in place of potable freshwater for cellulosic ethanol production (in both ...

Reusing Municipal Wastewater for Ethanol Production

Reusing Municipal Wastewater for Ethanol Production

This project blazes the trail for future ethanol production facilities to use treated wastewater effluent as a substitute for freshwater resources. Iowa is the largest producer of ethanol in the United States, and water demand is one of the biggest environmental downsides to ethanol production. Reusing wastewater effluent minimizes the negative impacts of ethanol …
