Minimize Dependency on Deep Wells 

Cost-effective Solution for Treatment of Produced Water to Discharge 

Quality 

Robust Technology to Treat Produced Water Highly Variable in 

Quality (30,000 ppm to 300,000 ppm) 

A Reliable Solution with High Availability and Long-Term Certainty 

Reduce Truck Traffic and Carbon Emissions 

Ability to Recover Valuable Resources from Produced Water 

A Commercial Solution that will Minimize Long-Term Risk 

Client Needs 

3 
Necessity for Gathering & Equalization 

600 trucks/day unloading the feed water for treatment 

High variability in feed water with field-wide truck deliveries 

Necessity for Pretreatment 

To control scaling issues due to specific ions in feed water 

To control fouling issues due to oil and solids

To control corrosion issues due to specific ions in feed water 

Necessity for Thermal Technology 

High feed water TDS - need for crystallization solution 

Necessity to achieve Zero Liquid Waste to minimize disposal costs 

Necessity for Post Treatment 

High concentration of dissolved gases in feed water (ammonia, benzene, VOC’s) 

Residuals Management 

Large quantities of sludge and salt - offsite vs. onsite landfill 

Treatment Challenges 

4 
Confirmed Treatment Efficiency

Process Goal 

Truck unloading and equalization 

Particulates and specific ion removal 

Truck Unloading 

600 trucks/day unloading facility 

Equalization 

Manage influent variability and flow variations 

Multiple-stage equalization processes 

Clarification 

Particulates removal (free oil, solids) 

Specific ion removal 

Multiple-stage clarification processes 

Solids-contact reactor clarification technology 

System fully Covered and gas blanketed 

To Prevent any potentional emissions 

Key Benefit 

To control downstream scaling and corrosion 

No liquid waste generation from the processes 

Pretreatment 

7 
Process Goal 

Removal of dissolved solids 

Zero Liquid Waste treatment objective
