The world’s best filters

Hydrotech as part of the french group Veolia, produces top-quality, market-leading water treatment filters for aquaculture, municipal, and industrial applications. More than 13,000 Hydrotech filters have been delivered and adopted worldwide.

The original microscreen filter.  

Hydrotech was founded in 1984 to supply solutions and products to the Aquaculture market. Our first invention was the Triangle Filter, quickly followed by the Hydrotech Drum Filter. In the mid-1990s we introduced the Hydrotech Disc Filter to the microscreen market. Hydrotech’s ongoing commitment to innovation can be seen in the 2025 launch of both the Hydrotech Hybrid Disc Filter - where drum filter performance meets disc filter technology, and within the Hydrotech Cloth Filter Confidence series  - where pile cloth media filtration technology supports the evolving filtration needs of industry. At Hydrotech - we have filter solutions to support all your water quality demands.

In 2002, Hydrotech became a part of the French group Veolia, one of the world’s largest companies focused on different solutions for water and wastewater treatment.
