Zero Liquid Discharge : Ethanol Plant Finds New Way To Save Water
POET Biorefining in Bingham Lake, Minnesota, has developed a way to be more efficient in the ways they produce ethanol. After two years of research, they started working on a process that we're now calling zero liquid discharge. And they've implemented this new process in January of this year. Bingham Lake is the first plant in the POET system to start up the patent pending "zero liquid discharge" system. The goal is to reduce water usage from 3.2 gallons of water per gallon of ethanol, to 2.6 gallons of water, a 23 percent decrease.
They've gathered all of the different locations throughout the plant that previously discharge water to the treatment system. They've recollected and filtered several streams. So now they are internally using all their effluent.Even though operating costs will increase,the water bills have already started to drop in Bingham Lake.
