Advanced Filtration Dynamic Membrane Technology

CORNCOB advanced filtration dynamic membrane technology can convert nearly any wastewater stream into clean reusable water in a small footprint, Decentralized Wastewater Treatment System (DEWATS). Compared to innovative DEWATS biological processes, such as FMBR, CORNCOB is ideally suited for wastewater streams that are less suitable for biological treatment such as landfill leachate.

Case Study: CORNCOB Landfill Leachate Solution

A medium size municipal landfill in Monroe County, Wisconsin faced the threat of shutdown if it could not solve its growing leachate problem. It’s average daily leachate production was 10,000 gallons per day which was hauled and disposed of offsite 365 days per year.

The Corncob solution provided an onsite landfill leachate treatment & recovery system that recovered clean NPDES permittable water and eliminated the need for offsite hauling and disposal.

4. Optimize Mixing & Aeration

Wastewater lagoons often do not have sufficient mixing or aeration to achieve optimal results. Mega bubble mixing can provide an effective mixing and aeration solution at low cost, enabling naturally forming microbes to produce superior results. (See Example Application – mega bubble mixing in an anaerobic zone of a wastewater treatment process)

Wastewater Lagoon Problems Worth Solving

  • Sub-optimal Ammonia Removal
  • Elevated TSS levels in Lagoon Effluent
  • Increasing Biosolids Dredging and Disposal Costs
  • Decreasing Lagoon Processing Capacity

PFAS chemicals Per- and polyfluoroalkyl substances (PFAS)

PFAS Contamination – Key Things to Know

PFAS contamination of water resources has made the national stage recently. (See: Toxic ‘forever chemicals’ more common in tap water than thought). PFAS chemicals Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that are very persistent in the environment and can accumulate over time in the human body.

Health Effects

Wikipedia: The most comprehensive epidemiological studies linking adverse human health effects to PFASs, particularly PFOA, come from The C8 Science Panel.[18] The panel was formed as part of a contingency to a class action lawsuit brought by communities in the Ohio River Valley against DuPont in response to landfill and wastewater dumping of PFAS laden material from the West Virginia Washington Works Plant.[19] The panel measured PFOA (C8) serum concentration in 69,000 individuals from around DuPont’s Washington Works Plant and found a mean concentration of 83.0 ng/mL, compared to 4 ng/mL in a standard population of Americans.[20] From this panel, 35 studies investigating probable links between elevated C8 blood concentration and specific health outcomes were determined by measures of association and are summarized below.


    Environmental Effects

    US EPA: PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time.

    PFAS can be found in:

    • Food packaged in PFAS-containing materials, processed with equipment that used PFAS, or grown in PFAS-contaminated soil or water.
    • Commercial household products, including stain- and water-repellent fabrics, nonstick products (e.g., Teflon), polishes, waxes, paints, cleaning products, and fire-fighting foams (a major source of groundwater contamination at airports and military bases where firefighting training occurs).
    • Workplace, including production facilities or industries (e.g., chrome plating, electronics manufacturing or oil recovery) that use PFAS.
    • Drinking water, typically localized and associated with a specific facility (e.g., manufacturer, landfill, wastewater treatment plant, firefighter training facility).
    • Living organisms, including fish, animals and humans, where PFAS have the ability to build up and persist over time.

    The extent of confirmed contamination of water resources with PFAS continues to grow at a significant rate. As of May 2020, 1,582 locations in 49 states are known to have PFAS contamination in water resources. An interactive contamination monitoring map can be found here:

    What are some key first steps?

    • Study this PFAS contamination map to see if it is a problem in your area.
    • Discuss this issue with customers and others who are informed. Is it on their radar?
    • Check back frequently. We will be focused on this issue for the foreseeable future and will provide updated info on our site.

    The Carbon Footprint of Water

    The Carbon Footprint of Water

    The Carbon Footprint of Water

    The carbon footprint of water is a modern way to talk about reducing water and energy and to create new environmental services. But there are some nuances in how you look at things which are important in making air and water cleaner. There is a major movement sweeping across corporate America, cities and states to de-carbonize. It’s for good reason based on what science is telling us. This is a perfect time to catalyze a new phase of growth for your environmental water business.

    A carbon footprint is the total green house gas (GHG) emissions caused directly and indirectly by a person, group, event, or product (Center for Sustainable Systems, University of Michigan). The key measure is carbon emitted to the air as carbon dioxide (CO2) which is commonly in metric tons.

    Giffiths-Sattenspiel and Wilson (The Carbon Footprint of Water 2009) estimate water lost in the U.S. due to leaks equals about 2.28 metric tons of CO2 per million gallons of water. Here is an example for a cooling water treatment system (make sure you get valid local numbers for local carbon footprint work).

    Cooling Water Example
    If a cooling water treatment system saved 2 million gallons of water each year, how many metric tons of CO2 emissions would be eliminated?

    2.28 metric tons CO2 X 2 million gallons = 4.56 metric tons of CO2 emissions eliminated.

    The problem of excess carbon

    High carbon levels in the air are harming the way we live – more floods, droughts, extreme weather, etc. I learned about this in the early 1990’s as a grad student in “Global Environmental Policy,” taught by Professor William Moomaw, Tufts University, Fletcher School of Law and Diplomacy. Here is a short piece of the science.

    The Scripps Institute of Oceanography, University of California San Diego began to monitor CO2 in the sky in 1956. Below is their data up to May 5, 2020, referred to as the Keeling Curve.

    carbon chart

    The Scripps CO2 Program is led by UCSD Professor Ralph Keeling, son of the late Keeling Curve creator Charles David Keeling who founded the program in 1956. Dr. Keeling puts it like this.

    “Prior to the onset of the Industrial Revolution, CO2 levels had fluctuated over the millennia but had never exceeded 300 ppm at any point in the last 800,000 years. In 2013 CO2 levels exceeded 400 ppm in the air for the first time in human history. We keep burning fossil fuels. Carbon dioxide keeps building up in the air. It’s essentially as simple as that.”

    Why is less carbon good for water business?

    1. Strengthen the case for water and energy savings projects

    By adding the reduction of CO2 emissions in your water and energy savings, you will strengthen the business case for your proposals. You may also get free brand exposure from your client’s low- or no-carbon success stories.

    2. Enhance relationships with corporate buyers

    As of March 2019, 101 major corporations have committed to reduce carbon emissions such as Cargill, Land O Lakes, Coca-Cola, Ford, and Hyatt to name a few (Forbes). Helping clients reduce carbon emissions is a great way to enhance corporate relations.

    3. Attract and energize youth

    Climate and environment are of top importance to our youth. They will be energized and attracted to a low/no-carbon initiative by a water company.

    4. It’s what people expect of water leaders

    Everyone wins – business, employees, communities, and future generations.


    Something to think about:

    • What clients or prospects have a sustainability initiative?
    • Do they have a CO2 or carbon reduction target?
    • Who is the director of sustainability?
    • What does he/she care about?
    • How can you solve their problems?
    • Talk to young people. Get their perspectives.
      The DNA of “Bourbon Gumbo”

      The DNA of “Bourbon Gumbo”

      A Microbe Detectives’ Classic DNA Study

      For those who missed the opportunity to get a good laugh and learn something about DNA sequencing, this is worth a read, reposted from the originals. Apparently this fella swimming in Bourbon Gumbo did not get the memo.

      What’s Living in “Bourbon Gumbo” Street Water?

      Have you ever been to Bourbon Street in New Orleans? Microbe Detectives got back from a great week at WEFTEC in New Orleans. We really enjoyed the culture, amazing food and great music, and it was a very successful business trip. However, we spent several nights on Bourbon Street (UGH!).

      We just could not resist finding out what kind of microbes might be living in the street gutter water (known as Bourbon Gumbo). So we decided to grab a sample and sequence the DNA of it’s microbiome.

      Where does the term “Bourbon Gumbo” come from? – from our Uber driver. We told him we wanted to analyze the microbiology of one of the water puddles on Bourbon Street, and he told us “that’s known as Bourbon Gumbo.” He said “that’s some really nasty stuff,” and started an out of control laughter. We asked a graduate student in environmental engineering at the University of Illinois (whom we met on the plane ride home) what she thought was in “Bourbon Gumbo.” She said, “I’m not sure but it was definitely bubbling and probably contains anything gross that can come out of the human body.” She also thought it was funny, nasty and interesting that we are going to sequence the DNA of the microbes.

      Now our “Bourbon Gumbo” was sampled on Thursday September 28 at 1pm. We have been told that the streets are cleaned and hosed down early every morning. So maybe we will not find what might be found later in the night, but we are not sure.

      Street Water Findings: #2 was #1

      DNA Analysis Report

      Turns out, it was a bit more interesting than that.

      The water was analyzed using DNA sequencing to identify the bacteria present. The high abundance of the Firmicutes Phylum is unusual for clean surface water and indicates potential fecal contamination. Though no obvious pathogenic genera were detected, 32% of identified bacteria was dominated by fecal-associated bacteria, especially Prevotella, Bacteroides and many others. Most of these bacteria live in mammal intestines including the human gut. However, Prevotellais generally not that abundant in the human gut in the Western Hemisphere (though it is quite common in some developing countries with diets lower in fat and protein).

      As a result, it seems that the presence of these fecal bacteria is likely predominantly due to manure from a large mammal. Several of the bacteria are associated with ruminate mammals. Since Bourbon Street hosts many celebrations and parades, it’s likely we’re seeing the aftermath of some horse manure festering in the puddles on the street.
