Installations, Pilots and R&D


The Algal Scientific Hypertrophic Water Treatment process was first developed in 2009 and since that time extensive laboratory and field research has been conducted.  The purpose of the research has been to determine which types of process water the technology can address, and the performance metrics that can be expected.

The following list highlights the research, pilots and an example installation.

  • Commercial Installation


    After conducting a 3 month pilot early in 2014, construction began on a  full scale installation at one of the world’s largest malt plants.

    That installation began treating the full flow of the plant (1.8 million gallons per day) in mid-December 2014.

  • Bench-Top Piloting

    Based on customer inquiries, we have tested the performance of the Hypertrophic technology on  variety of process water sources.  We will take a 5 gallon sample from the customer, and under similar environmental conditions as would be found in a commercial installation, test for metrics like BOD reduction rates as a function of the hydraulic retention time in the aerated  tanks (determines the size of tanks that may be required), the need for any supplemental nutrients, pH adjustments and affect on the microbial community.  Among the process waters we’ve tested are:

    • Dairy whey
    • Ethanol thin stillage
    • Meat rendering
