Technologies & Services for Water and Wastewater Treatment

Veolia Water Technologies provides expertise and experience in water and wastewater treatment for all aspects of the oil and gas sector. 

 

Water is vital to the production process at oil and gas facilities.  Veolia Water Technologies understands the issues related to water and wastewater management and has experience in helping customers achieve their goals to:

  • Lower the cost of production
  • Minimize risks associated with maintenance downtime
  • Ensure compliance with environmental regulations
  • Extend the life of your systems
  • Expand your treatment capacity

 

Water is a major component in all phases of oil and gas production Veolia provides sustainable management solutions for handling and treating produced water, and for production of water injection. With innovative technologies and a long history of serving the industry, Veolia provides solutions both onshore and offshore for:

  • Enhanced oil recovery (EOR)
  • Treatment of injection water
  • Treatment for beneficial reuse of produced water
  • Treatment of produced water for surface discharge
  • Treatment of produced water from gas production
  • Water treatment for the midstream sector: Liquefied natural gas (LNG), Floating LNG, etc.

Produced Water Treatment Solutions for SAGD Production

Evaporation technology is an accepted method of treating oilfield produced water from enhanced oil recovery operations such as SAGD and CSS. This thermal process provides high-quality distillate as feed water for steam generation and allows the flexibility of using either traditional OTSGs (once-through steam generator) or drum-type boilers.

Veolia Water Technologies has developed process technology for cost-effective treatment of produced water containing high levels of silica and other scaling components. This technology, called the Silica Sorption Process, is designed specifically for produced water treatment. The scaling tendencies and organics levels of produced water make it a challenging application.

Deoling Technology

Veolia provides highly effective deoiling systems for produced water. This includes both mechanical induced gas flotation (IGF) and walnut shell oil removal filter (ORF) technology.

The AutoFlot® IGF, coupled with Power Clean® walnut shell ORF systems, provides a process train that effectively reduces free oil and solids by 90-95% with maximum inlet concentrations of 300 mg/l of free oil and less than 150 mg/l of total suspended solids.

Case Study - Shell Pearl GTL

Our partnership with Shell and Qatar Petroleum in the Pearl GTL site enabled the installation of advanced technologies to reduce its environmental impact – with our zero liquid discharge (ZLD) technology completely manages effluent and process water in a closed circuit. Effluents and process water are fully managed in a closed circuit. The wastewater treatment capacity reaches 45,000 m3 per day.

Raw water treatment

Water is a major issue during downstream oil and gas processes. A quality product is essential for the smooth running of refining processes. Therefore, we provide our customers with raw water that is healthy and safe. Raw water treatment applications include: 

  • pre-treatment of process water;
  • production of process water to be fed to boilers and to be used as cooling water; and
  • production of demineralized water for the dilutions that are necessary in petrochemical processes.

Wastewater treatment 

Veolia Water Technologies treats wastewater generated by oil and gas industrial processes during downstream activities in them. Our mission consists in treating wastewater, rainwater and industrial effluent before it is reused or discharged. Our treatment process aims to purify the water of elements that are toxic to the environment. Such pollutants may be of any kind. They include, for example hydrogen sulfide, DOC, ammonia, hydrocarbons, oils, phenols, DBO, mercury, cyanides,  selenium, and chlorides.

Groundwater remediation

To remove dissolved and dispersed hydrocarbons in water, Veolia Water Technologies uses Macro Porous Polymer Extraction (MPPE) water treatment technology. This patented technology has a success rate of 99.9999%. Particularly effective, this technique has many advantages. It is a process that generates little noise but is also economically advantageous because it is inexpensive and does not require the addition of chemicals. We offer an automated, remote-controlled, and fully guaranteed process.

Water recycling and reuse

At Veolia, we safeguard water and enhance its recycling value by optimizing its potential for reuse, through our portfolio of 350 proprietary technologies that cover water issues, in particular during downstream industrial operations.  By recycling wastewater, we minimize the need for freshwater. Veolia offers a full range of technologies as well as technical solutions for wastewater treatment and processes to maximize water reuse. 

Case Study - AnoxKaldnes™ MBBR Proves Effective at Asphalt Refinery

Technology: AnoxKaldnes MBBR Technology

Location: Northeastern United States

The refinery needed to upgrade the wastewater treatment system to prepare for expected changes brought about by the use of a new crude feedstock. The new wastewater was predicted to contain elevated concentrations of TDS and conductivity.


Veolia Water Technologies supplied an AnoxKaldnes™ Moving Bed Biofilm Reactor (MBBR) treatment system to reduce the BOD and ammonia in the effluent at an asphalt refinery in the Northeastern US. Veolia provided the process and detailed design engineering to size the MBBR system, specifying all components in chloride-resistant materials of construction because of the high chloride concentration of the wastewater (3,500 mg/l). Equipment included the MBBR media, blowers, instrumentation and custom-designed aeration basin laterals and effluent sieves fabricated from Zeron 100 and 2507 SS. Veolia also provided start-up assistance and process engineering support that enabled the biological system to successfully acclimate to the high-TDS wastewater.
