Karl Spiegl GmbH & Co. KG

​Company development

 

Every year, Karl Spiegl GmbH & Co. KG plans, develops, and builds around 1,000 water treatment plants of all sizes and for all areas of application.

From the outset, the company has been involved in drinking water treatment for private households and properties, with a focus on the treatment of process water in the industrial sector. Through ongoing development activities, further applications have gradually been added. For 20 years, membrane technology, with a focus on “reverse osmosis,” has been an integral part of the production portfolio. Over the last 25 years, the portfolio has been increasingly expanded to include industrial applications with high requirements.
 
The main activities in recent years have been complex systems and applications with special requirements regarding product water quality, with a focus on the microbiological condition of the water.

In addition, developments are carried out for original equipment manufacturers, especially with regard to their quality requirements.
​
The field of membrane technology is also being continuously expanded. Systems for water recovery and plants with closed circuits and integrated water purification have now been implemented.
