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.


Applications for the purest water possible

With our plants you can implement the highest standards of water quality.

Whether for water treatment, waste water treatment or water circulation management – with our applications, all waters can be treated to the required quality. Our goal is to recover as much water as possible for reuse and thereby minimise the volume of waste.

Process technologies for water treatment

When developing our plants, we rely on most proven process technologies. This is how the H+E Group ensures that you receive the best solution to meet your specific requirements.

Depending on the task and industry, we combine different technologies: thermal and chemical-physical technologies, aerobic and anaerobic as well as membrane filtration technologies. Furthermore, H+E offers you the world’s most economical zero liquid discharge solution.
