Gross-Wen Technologies

Gross-Wen Technologies uses its patented wastewater treatment technology, known as the revolving algal biofilm system (RAB), to cost-effectively recover nutrients such as nitrogen and phosphorus from wastewater. Compared to other treatment options, our system is significantly more affordable and produces algae biomass which can be sold as a slow release algal fertilizer or bioplastic. Gross-Wen Technologies exists to help municipalities and industrial clients sustainably treat water in more effective and affordable ways! Our technology was developed at Iowa State University, and from there, we’ve grown into a trusted source for environmentally friendly wastewater processing.

Sustainable and Effective Water Treatment

Since our company’s conception, our mission has been simple: to provide algae-based water treatment that is sustainable, effective, reliable and affordable. We’ve reinvented the way nutrient pollutants are viewed through our process of extracting nutrients from wastewater with algae then recycling those nutrients through a fertilizer or bioplastic product.

Not only will our wastewater treatment process help you meet your new water quality standards, but it’s also the most sustainable wastewater treatment on the market today. Our technology uses algae to capture nitrogen and phosphorus from the wastewater. This phosphorus and nitrogen rich algae can then be sold as a slow-release algal fertilizer so that your water’s useful byproducts don’t go to waste!

Our process has been approved during an evaluation process by the Iowa regulatory agency IDNR. This means the technology is not only effective but also has gone through the regulatory process to confirm it is a safe and reliable option to treat wastewater.
