Ecolotron Flow Back Brochure

Ecolotron, Inc. manufactures “State – of – the – Art” electrolytic reactors and turn - key wastewater treatment systems used in a variety of water and wastewater treatment applications. Under license from The VG Group, Ecolotron, Inc. applies patented technology to provide custom engineered, design and build electrocoagulation systems for the treatment of frac, flow-back and produced waters associated with oil and gas exploration and production activities.Overview:This demonstration focuses on the beneficial reuse of flow-back and produced water resulting from the (slick water) hydraulic fracturing of oil bearing shale in the Eagle Ford formation of McMullen County, Texas. The system discussed in the forthcoming paragraphs has a design flow rate of 3.5 to 8.0 (bbl/min). The purpose of the demonstration is to produce water acceptable for beneficial reuse in oil well drilling, completion, fracturing and cementing, or for safe discharge to the environment. Photos and laboratory results follow in the forthcoming pages.Patented Process:The E – FLOC patented process utilizes an electric current to sacrifice beneficial ions (Fe / Al) into solution while simultaneously liberating oxygen and hydrogen gas via electrolysis. The beneficial ions, evolved gases and their byproducts react with both dissolved and suspended contaminants to facilitate their precipitation (co-precipitation) from solution and subsequent removal from the treated water. In like manner, oil and grease, suspended solids and bacteria may also be destabilized and removed. Liquid– Solids separation occurs via gravity settlement or dissolved air flotation, depending on the application.From Customer:100 GPM50 % H2SO43000 GallonEquilizationTank Electric Pump:100 GPM @ 80PSI100 GPM E-FlocReactor 50 % NaOH3000 GallonReactionTank 100 GPME-Floc/Clarifiedto Customer100 GPM ElectricBooster Pump:pH ProbepH ProbeElectricMixerElectricMixer1000 GallonClear Well300 GallonSludge HoldingTank PD SludgePumpFlocculant (If Needed)2000 GalonSludge TankContainerizedE-Floc PowerRectifier480V/3 Phase/60HzDO NOT SCALE DRAWING SHEET 1 OF 1SAUNLESS OTHERWISE SPECIFIED:SCALE:1/100 WEIGHT: REVDWG.

The major contaminants include: Total Suspended Solids (“TSS”); Bacteria; Volatile Organic Compounds (benzene, toluene, ethyl benzene, and xylene); Total Petroleum Hydrocarbons (“TPH”); Metals; and Chlorides.E-Floc electrocoagulation technology is successful at reducing TSS, TPH, Calcium and Iron by > 90% and SRB, Sulfite, Silica, Strontium and Barium by > 80%. These contaminates must be removed to allow these waters to be reused in future E & P applications. These same contaminates may also foul or scale Reverse Osmosis membranes and their removal is therefore essential before proceeding to tertiary polishing systems and environmental discharge.Results indicate that E-Floc technology with subsequent membrane polishing is effective for removal of Chloride to <1500 mg/l making it acceptable for discharge to the environment. Chloride concentration in the raw flow-back was reduced from ~18,800 mg/l to 96.3 mg/l, >99% removal.E-Floc electrocoagulation technology provides an efficient / effective means to “clean” flow-back and produced waters to acceptable levels to be reused as make-up water for drilling, completion and other production activities. E–FLOC technology with membrane polishing produces a desalinated effluent that is safe for land irrigation or discharge with minimal impact to the environment and existing water supplies.All information in this document may be considered confidential and subject to the terms and conditions of existing nondisclosure agreements.
