About H+E

The H+E Group, headquartered in Stuttgart, has already implemented 30,000 plants in the field of industrial water treatment, waste water treatment and water recovery. This makes the company one of the world’s leading plant manufacturers. For all projects that our teams develop for our customers, we rely on innovative technology “engineered in Germany”. With our global network in ten countries, we also guarantee direct proximity to our customers. This is why companies from a wide variety of industries and from all over the world place their trust in H+E.

Company founder Willy Hager laid the foundation for H+E as early as 1932 in Stuttgart. Since then, the company has continuously expanded its expertise, also through its affiliation with well-known corporate groups. The takeover of Permutit GmbH Berlin was a milestone in the company’s history. H+E, then still under the Hager+Elsässer name, considerably expanded its experience in the planning and design of large-scale plants with the acquisition of this well-established company.

We owe most of our technological expertise in waste water treatment and pre-treatment with biological aerobic and anaerobic processes to Philipp Müller GmbH Apparatebau, which has been active in this field since 1896. The H+E Group integrated this long-established company into its core structure in 1999.

In 2016, H+E completed its portfolio with the acquisition of Membran-Filtrations-Technik GmbH (MFT), based in Cologne, Germany. This has enabled significant technological expertise to be brought together and further developed into innovative concepts – for almost all production-based industries. Since 2014, the group of companies with locations in Europe, South America and Asia has belonged to the listed Swiss Aquarion AG.

High-quality components, long-term supplier relationships and comprehensive aftersales service guarantee reliable plants with high availability. They are planned, designed and built by our engineers in Stuttgart. H+E works together with local companies in more than 130 countries – true to the “Think global, act local” guiding principle.

Our industry-specific solutions are precisely tailored to the needs of our customers. We guarantee this with all processes that are known and used on the market. Moreover, as a forward-looking company, we continuously invest in the research and development of new technologies. All this, because our goal is effluent-free production – to protect our most precious resource: water.

Our current Joboffers


Highly skilled in many sectors

The global demand for raw materials and energy is increasing year by year. Therefore, the extraction and processing of oil and gas needs to be further optimised. At the same time, legal requirements are becoming more stringent. The economical H+E systems meet all these requirements and work in an energy-optimised and reliable manner.

H+E offers close to 50 years of experience in the semiconductor and solar cell industry. On this basis, we develop customised plants for you – precisely tailored to your requirements: from a new concept for a water treatment plant through its expansion to adaptation due to regulatory changes.

Water plays a vital role in the production of food and beverages. H+E’s plants provide energy-efficient, cost-effective and reliable treatment and the purification of all waste water that arise during production – whether for a sugar manufacturer, a dairy or brewery.

For the production of pharmaceuticals and the sanitation of tools, H+E offers intelligent turnkey solutions as well as standard plants. With their decades of experience, our engineers develop exactly the right system for you – using a wide range of processes: whether chemical-physical, thermal or membrane filtration with a polishing stage.

Close to 500,000 cubic metres of waste water from paper and pulp production are treated every year in Germany alone with H+E plants – and this is carried out with both ecological and economic viability in mind. With our process-stable and energy-optimised technologies, we also support you in the production of process water.

With over 500 projects successfully implemented worldwide, the H+E Group is an expert in water treatment plants for all types of power plants. Whether for conversion or new construction, our practice-proven approaches ensure that all requirements are met in terms of efficiency and environmental friendliness. This applies equally to coal, oil and gas.

H+E has been active in the chemical industry for over 50 years. You can achieve several objectives with our plants for water recycling and partial flow treatment of toxic waste water: your water consumption drops, you comply with the strictest discharge limits and you can realise zero liquid discharge (ZLD) with complete water circulation.
