Brewing up Solutions for Nutrient Removal Optimization

Many communities throughout the United States are increasingly dealing with stringent nitrogen effluent limits, leading many to invest in costly nitrogen removal infrastructure upgrades at their wastewater treatment plants. Often, one of the limiting factors within a nitrogen removal process is the availability of carbon. In these situations, communities must often inject alternative carbon sources such as microC, glycol or methanol, which can be both expensive and create hazards with respect to storage and handling.

Separately, increased demand for craft beer and spirits has resulted in a boom in the micro-brewery and distillery industry. As with anything “micro,” cost control is critical in order to ensure long-term financial viability since the volume of product is limited.

One potentially significant cost to microbrewers can be the cost of treating and hauling the waste by-product to an appropriate disposal site, or paying the municipal fees associated with discharging high strength waste into a public collection system.

In 2017, HDR tasked its employees to develop innovative ideas that were judged collectively by their peers. This process enabled the creation of a pilot program in 2018 that studied the viability of using brewery and distillery waste as a cost-effective carbon source for nitrogen removal in treatment plants.
