## 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

High quality treated water meeting target specification



## Validated Operating Costs

Chemicals and power demand, sludge and salt generation



## Validated the Ability to Produce By-Product Salts

Sodium chloride and calcium chloride characterization



## Validated Scaling and Corrosion Characteristics

Identified pretreatment contaminant removal requirements



## Determined Solids Settling Characteristics

Optimum sizing of clarification and dewatering equipment

QUALITY

WATER

### 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



## CoLD ® 

## Crystallization Technology

Operates at low temperature, deep vacuum

Mixed salts generation suitable for onsite landfill

Ability to recover by-products (NaCl, CaCl

2



### )

Effective desalination of produced water



## Key Benefit

Lower OPEX costs than conventional approach

No calcium removal ahead of the crystallizer

Requires less pretreatment than conventional approach

Less sludge generation than conventional approach
