ECO NRG SYSTEMS LP exclusively represents, UEM, Inc., in the pulp and paper industry in North America.  UEM Group (www.uemgroup.com) is an international engineering and construction company with an office in West Palm Beach Florida offering the Hybrid Anaerobic Treatment System. UEM provides services in the water and wastewater treatment field and has successfully implemented over 300 installations (Turnkey design build and operating) to include Aerobic and Anaerobic Digestion in many countries, over 100 of which are anaerobic/power generation. UEM has been implementing Turn Key systems for over 20 years in several industries.

Our system is designed and built as an alternative wastewater treatment system that generates energy and saves on your production cost while keeping the current treatment system intact.

Our system treats your waste water prior to your current Aerobic system.  Methane generation is proportional to COD removal and therefore the higher the COD concentration in your waste water stream the more methane will be generated.  Our system provides up to 90% in COD removal. We can help identify and segregate the high strength wastewater streams  by conducting a site visit of the industrial operations.

We are currently working with several companies in North America and have been able to quantify savings between $2,000,000 to $9,000,000 per year.

The savings from our system are from the following:
• Biogas generation replacing natural gas usage in plant or using it in an engine to generate electricity
• Power and chemical savings from the use of your current aerobic system (no aerators required in anaerobic.  It operates in the absence of oxygen)
• Sludge disposal savings (80% less sludge generation than your current aerobic system).
• Carbon credits in the form of fuel switch
• Increased mill throughput by increasing waste water capacity
• Taking current load off the existing aerobic system thereby giving it more ability to meet discharge permits consistently.       

The savings will be based on your waste water COD concentration and flow rate.  We could determine the potential of your system with a few preliminary calculations.

The bio gas generated contains up to 80% methane with the balance Carbon Dioxide, moisture and some H2S.  The energy value of that gas ranges from 600 to above 700 BTU/ft3.  The gas can either be used in the plant’s boilers, sludge dryer, or even in a package generator (reciprocating or micro turbines) which we also provide as part of the turn key solution for generating electricity.

The UEM system is a Hybrid Reactor which incorporates two technologies
• UASB (Up flow Anaerobic Sludge Blanket)
• Fixed Media (top portion of the digester)

The advantages of our system over an Aerobic system:
• Consumes less energy (no oxygen required, no aerators needed)
• Less biological sludge generation and sometimes complete degradation.
• Requires less nutrients
• Generates beneficial gas (Methane) that is used as energy source
• Can survive for long periods of time without feeding
• Has a strong environmental benefit (green foot print)
