The Solenis Story

Whether you’re an engineer or a plant manager, whether you work in a paper mill, power plant or other industrial facility, we can help you improve your results. We’ll assess your unique needs and challenges and match them with the right experts and solutions.


That’s exactly what we’ve been doing since our founding more than 100 years ago. Today, we are a leading global specialty chemical supplier and one of three water treatment companies with a truly global footprint. We have 5,200 employees and 39 manufacturing facilities, which span 120 countries and five continents.

Throughout our rich history as Drew, Betz Laboratories, Hercules, Stockhausen and Ashland Water Technologies, our guiding principle has never changed: Our objective is to help you.

Strong Bonds. Trusted Solutions.

Whatever your water and process needs, we can help. With the three core elements of our business—people, experience and technology—Solenis is ready to deliver the solutions you need. Together, we’ll create strong bonds that ensure trusted solutions.

It all starts when you tell us about your toughest challenges. We’ll then match you with a team of experts who will troubleshoot your problems and specify industry-leading technologies to address your needs. And, we’ll continue to work with you to ensure your ongoing production and profitability goals are achieved.
