Hydraulic Fracturing Flowback Water Treatment

FLOWBACK WATER TREATMENT OVERVIEW

Global Advantech has developed systems, which will efficiently treat flowback water arising from hydraulic fracturing (fracking) operations and for pre-treatment to remove undesirable components from water used to make up fracturing injection solutions. The systems utilise a number of process steps and incorporate innovative design features and benefits to ensure effective and continuous operation.

Global Advantech’s systems are able to remove the majority of sulphates, carbonates, selenates and other cations (divalent and higher), which may be dissolved in water, depending upon its source. The systems also remove dissolved heavy metals (including iron), alkaline earth metals (calcium, strontium, barium and radium), suspended solids and biological materials (bacteria, algae, larvae, etc.) These cations both contribute to acidity and solubilise heavy metals into solution, making these discharges hazardous to the environment.

Global Advantech’s treatment systems utilise:

• Combined chemical conditioning and electrocoagulation treatment to remove sulphate and carbonate cations, heavy metals, radio nuclides, hydrocarbons, most organic chemicals and suspended solids, whilst minimising the production of waste by-products.

• High pressure reverse osmosis to remove dissolved salts.
