Upflow limestone contactors
of constant height
Our research is our strength®
Since 2002, we manufacture custom limestone contactors using the most efficient design for the remineralisation of soft or desalinated waters, based on our internal research and development
The DrinTec™ design of upflow limestone contactors of constant height simplifies the reload operation by means of feeding the granulated limestone continuously, under water and directly on to the limestone bed by a limestone feeding system, thus maintaining a constant bed height all the time.
It‘s a very effective system that operates continuously for many years without needing to perform a backwash.
