Söll has already successfully renovated many waters with its patented methods. The positive results range from small garden ponds, fish ponds, lakes, EU bathing waters to large dams.

This concerned both the ecological desliming (sludge removal) of waters and the restoration of living conditions in heavily polluted or already dead waters. Thanks to decades of experience, our methods could be optimized up to the high degree of application safety we have available today. The methods have convinced scientists, fish farmers, public health officials and politicians, which our references confirm.
