Case Studies

CRAFT BREWERY WASTEWATER PILOT

  • The Challenge:

    Craft Beer is a growing market in North America, however, many Craft Breweries are at risk of receiving large environmental penalties due to their high strength wastewater.

    Traditional treatment options have been limited to “scaled down” versions of municipal type systems, and as such, they have higher capital & operating costs, and often require skilled technicians and a reliance on chemical treatments.

    These solutions don’t always meet the needs of the small to medium sized Craft Brewers.

  • Econse Solution:

    Starting in October 2015 until March 2016, Econse worked closely with several craft breweries in Ontario to develop a solution to specifically meet the needs of the industry

    • An affordable solution with simple operation & maintenance procedures
    • Small foot print for equipment
    • Able to handle the variations & fluctuations of the brewing process
    • Able to reduce wastewater strength to meet the discharge requirements
  • The project results were successful and showed that we were able to meet all discharge requirements with the BRÜ CLEAN SYSTEM.

  • The Results:

    Small to Large Craft Breweries and Brew Pubs will now be able to eliminate environmental penalties, and dramatically reduce their water usage in an affordable way and become environmental leaders in their Communities.

DRINKING WATER PILOT

  • The Challenge:

    Water scarcity is a growing concern around the world. Many regions are experiencing record droughts. Other areas have access to abundant sources of water, but the water is unusable due to a variety of reasons including: high levels of contamination, high cost of treatment in remote locations and expensive operation and maintenance costs.

    A remote city in Texas was chosen as the site to demonstrate the WATERHORSE’s capabilities in cleaning polluted (brackish) water from a well and producing clean safe drinking water.

  • The Solution:

    The ECONSE WATERHORSE is designed to purify water from a wide variety of sources, including wells, lakes, streams, and rivers. Our unique processes is designed to remove:

    • Total Suspended Solids
    • Total Dissolved Solids
    • Bacteria, Viruses, & Organic Matter
    • Precursors of THMs and HAAs
    • Heavy Metals, Nitrate, Phosphate, Sulfate, Hydrogen Sulfide
    • Colour & Odor
  • The WATERHORSE is a “pre-engineered” unit with plug & play installation. The system is fully automated, with remote monitoring and control, portable and housed inside a shippable shockproof and weather-proof container to eliminate building costs.

  • The Results:

    The WATERHORSE was able to meet and surpass all drinking water standards in the USA, Canada and WHO guidelines for Safe Drinking Water. Test results were confirmed by a 3rd party certified laboratory.

    This system has many applications including:

    • Immediate additional capacity for Municipalities
    • Primary Water Treatment for Small and Decentralized Communities
    • Provides water to Large Institutional Complex Buildings, Schools, Hospitals
  • Please contact ECONSE if your community is interested in a demonstration.

THM & HAA REMOVAL TEST

  • The Challenge:

    Public Water Systems add disinfectants such as chlorine or chloramines to protect drinking water from disease-causing organisms. These disinfectants also react with natural organic matters (NOMs) in the water and form chlorination disinfection by-products (CDBs).

    Drinking water containing THMs and HAAs in excess of Health Canada Maximum Acceptable Concentration (MAC) or EPA (MCL) level, could over many years cause problems with liver, kidney, or central nervous system, birth defect, early-term miscarriages, reproduction system disease and have an increased risk of cancer.

  • The Solution:

    Elimination of the precursors that cause THMs & HAAs is the best way to reduce the overall THMs & HAAs levels to below requirement. The ECONSE Advanced Water Purification Units such as our WATERHORSE are designed to remove THMs and HAAs precursors before primary chlorination.

    However for this test we looked at an inline secondary treatment as another way to provide solutions for communities with localized problems such as water towers and stand pipes.

    We performed a small-scale test to examine the effect of treatment on Total THM (TTHM) and Total HAA (THAA) as well as the effect on nine specific compounds that are regulated by the Health Authorities in Canada and The USA. Test Water was spiked to over 200 ppb of TTHMs and 200ppb of THAAs which represents more than 2 times the maximum regulated levels.

  • The Results:

    Test Results were verified by a 3rd party certified laboratory.
    Total THM were eliminated to more than 99% removal using our test equipment.
    Total HAA were reduced by 20% removal using our test equipment.
    In full scale applications our process would show over 25% reduction in THAAs.

PCB & POP Destruction Unit

  • The Challenge:

    The removal and decontamination of PCBs and POPs from water is a very difficult and expensive process, which creates additional pollution & waste due to the use of Incineration, Chemical Mineralization, and Reverse Osmosis technologies.

    ECONSE was asked by a Canadian Government Agency to propose a solution and demonstrate our capability to destroy PCBs in highly contaminated water.

    Additional goals of the project included:

    • Dramatically Reduce existing process cost
    • Find an ultimate, on-site remediation solution for the destruction of PCBs
    • Use advanced technologies with no hazardous byproduct(s)
    • Provide a chemical free, sustainable and eco-friendly solution
    • Comply and meet with safety discharge limits & environmental regulations
    • Provide a fully Automated Unit with remote monitoring & control
  • The water was contaminated with 120 (+/-) ug/l of PCBs & other contaminations.The “Safe for Discharge” requirement (non-drinking water) is 1 ppb (1μg/l).

    Our challenge was to destroy PCBs below “Non-Detectability Level”.

  • The Solution:

    The Econse 250R PCB & POP Destruction Unit uses an advanced chemical free process to destroy PCBs and POPs to below detectability “On-Site” without the need for any incineration or use of chemicals.

    The ECONSE-250R produces a water quality that meets and exceeds the Safe Industrial Discharge requirements of the Ontario Ministry Of Environment MOECC at a fraction of the cost of other traditional treatment technologies.

  • The Results:

    ECONSE preformed a demonstration of our technology at our facility in Toronto, Canada. All PCB and other hazardous contaminations were destroyed to below Non Detectability (0.02 ug/l), and water was made safe for discharge.Test results were verified by an independent certified 3rd party laboratory.

INDUSTRIAL WATER REUSE – GLASS FABRICATION INDUSTRY

  • The Challenge:

    Glass fabrication uses a high volume of water for edging and glass grinding. This is typical to many fabrication industries. Glass particulate accumulates in the water causing damage to machines and product as well as safety and environmental concerns for disposal and for employees.

    The existing Centrifuge technology used by the glass cutting industry for wastewater treatment could not eliminate particles below 45 microns and was not feasible due to bottlenecks created in the production line from the limited capacity and manual operation requirements.

  • The Solution:

    Econse designed and installed a modular system combining several processes for removing the glass particles from the wastewater, and allowing water to be reused and glass “sludge” to be safely disposed. Our durable membranes are the perfect solution to filter abrasive materials and our fully automated modular system is applicable to other industrial applications such as metal & water jet cutting factories.

  • The Results:

    3rd party lab tests proved that the ECONSE solution removed ultra fine particles to below 0.1 microns and produced wastewater suitable for reuse by the glass industry.
