KLARO - the Competence Center Wastewater of the GRAF Group

Since 2014 KLARO is a company of the globally operating GRAF Group.
The GRAF Group is the European market leader in the field of SBR technology (air-lift technology) with over 100,000 units sold.

While GRAF has stood for high-quality plastic products in the field of water management for more than 50 years, KLARO has been developing and producing top products in the field of clarification and separation technology for almost 20 years.
A merger of these two global players, who have been working together since 2002, is a win-win situation for all sides. Above all, our customers will benefit from the know-how and quality of two established brands in decentralized wastewater disposal when they purchase a KLARO clarification or separation plant.

As part of the takeover by GRAF, KLARO became the wastewater competence center of the globally active GRAF Group. Within the group, KLARO is responsible for developments in the field of clarification and separation technology. KLARO is thus the sewage technology product forge.
In addition, all technical measurements and designs are prepared at KLARO.
