                         What is it?
• The separation of contaminants from water using
  electricity and the physical separation from the water
  using stainless steel mechanical separators.
                     What is the result?
• Water that is reusable or clean enough for discharge, and
• Solids in a form that can be disposed into a non-
  hazardous landfill
With the use of clean electricity, the Electro Coagulation
Systems efficiently remove a wide range of contaminants
with a single system. The result is water that is available
 for reuse and the separated solids available for resale,
reuse, or for simple removal to a non-hazardous landfill.

               What it does:
• passes electricity through water using
  bipolar electric metal plates/blades.
• uses a patented chamber.
• converts alternating current (AC) to direct
  current (DC) voltage.
• destabilizes suspended, emulsified, or
  dissolved oil and other constituents in an
  aqueous medium.

Advanced Mechanical Separator
• After contaminated water is separated from
  the waste stream with electro coagulation, a
  Mechanical Secondary Separator is employed.
  The Advance Mechanical Separator.

                    Uses 0.10 and 0.05 micron filters
Advanced Mechanical Separator
          Post EC
• CWS and BME in concert with the manufacture’s electro
  coagulation, employs the use of a revolutionary
  processing system without having to use chemicals.

• Advanced mechanical separator (AMS) computer-
  controlled self-cleaning stainless steel separation system
  removes particles, minerals, or anything in solid form
  from production water.

• Different modules can be assembled to achieve specific
  stated objectives for cleaning various fluids.

     Electro Coagulation
Advanced Mechanical Separator
The combination of elements in the system creates a molecular separation
   between water and solids. This is accomplished through these steps:

•   Processing the raw product through stainless, sintered steel filters and air
•   Absolute filtration of solids to 0.05 microns.
•   Configuring the process to "target" different water and solids depending on
    the size of the filter used and the amount of air pressure applied.
•   Customizing each system to a small footprint which is energy efficient.
•   System design is fully integrated with pumps that are durable in many
•   Each system is scalable and modular, so large integrated systems can be
•   Maintenance is simplified through the self-cleaning function of the system,
    while it operates continuously under the management of field personnel.

        Electro Coagulation &
    Advanced Mechanical Separator
           Relative to Chemical Coagulation - CC
•   no chemicals; no chemical safety requirements
•   kills virus, cysts, & coliform bacteria
•   better removal capabilities than for CC
•   removes species that CC cannot remove
•   produces cleaner water and less sludge
•   sludge filterable; pass leachability tests
•   EC results in 80% less solids
•   Solids dewaters 76% faster
•   minimal setup time
•   no temperature effect
•   no moving parts; small footprint
       Electro Coagulation

• Currently, pretreatment to RO is low pressure
  membrane (UF or MF)
• But UF and MF still subject to silt and other SS
• Removal of suspended solids is most cost-effective
  application of EC & AMS
• EC better removes Fats, Oils, & Greases (FOG)
