The Issue

Industrial-scale wastewater treatment systems have the potential to save energy, reduce wastewater volumes, and generate pure water streams for on-site re-use. However, many industrial wastewaters are very difficult to treat, as they contain high levels of dissolved and suspended solids, making low cost treatment with membrane-based systems ineffectual.

Project Innovation

This project is demonstrating an advanced wastewater treatment technology that produces high quality water while reducing energy, chemicals and maintenance required for treatment of industrial wastewaters. The project includes technological advancements in membrane development and module design in forward osmosis to address cost and performance issues. The demonstration projects are located at a winery, frozen food facility and a soap company. Each demonstration will document energy savings and potential for this technology to purify, concentrate and reuse challenging wastewaters that contains high levels of contaminants. This technology has the potential for application in the food and beverage, oil and gas, and other industrial sectors.

Project Benefits

Treatment of industrial wastewater is very challenging because of the high solids, pulps, free and emulsified oils and greases and their high chemical and biological oxygen demand. If the project is successful then this technology could be used to treat challenging wastewaters to achieve high purity and provide high temperature water for reuse while using less energy than other processes. Reclaiming water for onsite reuse will reduce the need for fresh water purchases.

Lower Costs: This technology will treat challenging industrial wastewaters for water reuse and can result in energy and water saving benefits and also cost savings.

Environmental Benefits: By reducing electricity use and water use, the project could reduce greenhouse gas emissions. With broad adoption, the technology could enable the reuse of industrial wastewaters rather than being disposed in the sewer system.
