Treatment of galvanic wastewater

In surface treatment plants, a safe, efficient water supply is of decisive importance for production. This includes the provision of process water for rinsing baths and active baths, the recovery of rinsing water and recyclables, as well as the treatment of wastewater. This enables companies to face heightened legal requirements, increasing environmental awareness and growing cost pressure.

With our extensive knowledge and understanding of various industries as well as numerous technologies and processes, we are your expert partner for plants for water treatment, process-oriented recycling and wastewater treatment of streams containing cyanides, chromates, heavy metals, photographic lacquer or complex compounds.

The ongoing development of processes and plant concepts, along with numerous references, are based on our commitment to always offer you the best solution – process-oriented, efficient and as a fully integrated overall concept. Furthermore, H+E offers a wide range of services: from the initial concept through to 24-hour hotline.

Oily Water Treatment Offshore

For an oil rig, Ørsted needed a treatment plant for treating oily water from various sources. Ørsted, Denmark, is the world market leader in offshore wind energy and offers innovative energy solutions for public utilities and industry.

For an oil rig, Ørsted needed an oily water treatment plant to treat water from various sources to remove oil down to <10 mg/l and 95% of solids >100 μm, making the water suitable for discharge into the sea. This application was a particular challenge due to the small droplet diameters and emulsified oils from the various sources. H+E met the challenge by providing their coalescer design with a solids removal system upstream of the coalescer technology.
