SEBS for Frac Flow Back Water

Application / Problem:

Frac and Flow Back Water contain heavy Brine among other dissolve minerals and various additives. This contaminated water is not safe to use for anything or anywhere.

Shale Deposits in Frac Water Make-up 

From 1 to 10 million gallons of fracture, “frac”, water, mixed with various additives, is required to completion fracture each horizontal deep well. Once used, this now contaminated water must be removed from the well, generally 10 to 40% is recovered, and is commonly referred to as “flow back” water. Typically, flow back water contains high dissolved solids with varying levels of various other constituents such as barium and strontium.

Metals and acid-producing minerals 

Marcellus shale’s are known, in some regions, to contain acid-producing minerals such as pyrite and sulfides. Based on region acid forming minerals varies due to particular shale formations.


Due to the high dissolved solids content and presence of various other constituents, disposal of flow back water is becoming very difficult and costly.

Obtaining the needed water to makeup frac water, with subsequent disposal of the flow- back water, presents a significant problem for gas production firms. In many areas, the amount of suitable water needed for formulation of frac water is just not available.

The best solution to this combined wastewater disposal and water supply problem is to simply treat and recycle the flow back water, with our Eco friendly SEBS Microbial solution over and over again, to lower brine concentrations and lower various mineral concentrations. This process helps clarify water, & removes unwanted solids.

Contaminated water clean up can be achieved by a two-step process.

1. By using SEBS Bacterial system, Removing, Solids, Sludge, Heavy Metals, Hydrocarbons, and any inorganic waste dissolved in contaminated water.

2. By using flocculation treatment, settling contamination solids from the water to the bottom of ponds or tanks, leaving clean clear water on top before discharging. (see flocculent product data for details.)

SEBS Results:

  • Instant odor control and elimination.
  • Reduces Organic solids down to more than 80%.
  • Reduces ammonia Bods / TSS.
  • Digest and Liquefies waste plus.
  • Lower Brine concentration in Frac & flow back water.
  • Reduces concentration of Acid forming minerals.
  • Non-Toxic.
  • Non-Corrosive.
  • Non-Polluting.
  • Remediation of spills within secondary containment areas to insure compliance with ground water management plans.
  • The contamination is treated on-site, rather than simply relocating the problem. Liability issues are limited because the contaminated areas are treated on site.
  • A competitive project cost, generally thousands of dollars less than traditional “dig & haul” methods.

SEBS Bacterial systems are highly dedicated to the development and manufacturer of high quality environmentally friendly and responsible biotechnological products, utilizing natural resources SEBS systems incorporate specific technology to solve numerous industrial, commercial and institutional problems which result from waste.

Application Treatment:

1. Initial Treatment: For each barrel of Frac or flow back water (44 to 50/gal) use 50FL-OZ to 70FL-OZ OF SEBS. After the SEBS treatment let this solution stand for minimum 24 hours before reusing or discharging treated water.

2. Then follow up with flocculent applications (see product data for proper dosage). This treatment will help settle out heavy mineral particles and left over inorganic residues.

Treated Frac water can be transferred into separate holding tanks for secondary SEBS treatment. If needed, repeat steps 1 and 2

For Holding Tanks: Use 8 to 10 gallon of SEBS for every 1000 gallons of wastewater then follow up with flocculent applications. (See product data for proper dosage).

Note: Check water sample after each application. Follow steps one and two for better results until desired level is reached for proper discharge.

DO NOT AERATE after flocculants treatment; let set twenty-four (24) hours before discharging water.

Note: Pretesting of the water should be completed to note the amount of Brine Water Concentration in order to determine whether or not the SEBS dosage amount needs to be adjusted.
