Experts in water remineralization

We custom manufacture limestone contactors using the most efficient design for the remineralisation of soft or desalinated waters

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.
