Industrial Wastewater Treatment for the Oil & Gas Industry from H+E


A constantly expanding world population, together with the development of emerging economies, provides an ever increasing demand for energy and thus the extraction of global oil and gas reserves. The discovery and development of alternative energy sources and new hydrocarbon reserves struggles to keep pace with the demand profile and the drop in production from existing mature fields. This has led to an urgent need for the development of new techniques to optimize field recovery potential for new and existing reserves. HAGER+ELSÄSSER provides reliable, stable processes and energy-optimized wastewater treatment plants for the downstream sector, either as fully operational turn-key systems or as pre-assembled, skid-mounted solutions. Each of these options can be expanded in a modular manner, as necessary.

Challenges of our Customers

We need a temporary, containerized and if necessary expandable modular water treatment plant. Which system solutions can you offer?

We need a quick service or system evaluation of our treatment system. Can you support us – even if the plant was not designed and built by H+E?

We will get more stringent requirements for indirect discharge and therefore require expert assistance and solutions for the necessary actions like for example a suitable wastewater pretreatment. Can you help?

In the future we have to discharge the effluent directly and need expert assistance in the realization of our own wastewater treatment plant to comply with the regulatory discharge limits. Can you help us?

Due to new external factors, we are committed to partially or fully recycle our generated wastewater. Which process technology solutions can you offer? Do you have MLD/ZLD solutions?

Our existing water treatment plant needs to be modernized or replaced. Can you make us an offer for this?

Our biological wastewater treatment is regularly or permanently overloaded and we cannot meet the required discharge limits. Which technological solutions can you offer to us?

Our production capacity is expanded and our process and wastewater amount as well as composition will change. We need to expand our existing treatment systems – if possible during ongoing production. Can you help us in this matter?
