The world’s best filters
Hydrotech produces top-quality, market-leading water treatment filters for municipal, industrial, and aquaculture applications. Part of the French group Veolia, we have delivered more than 12,000 filters worldwide.

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.
Starting out as a small company in Vellinge, south Sweden, we are now represented in most countries throughout the world through a network of professional partners. 
In 2004, 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.
We have delivered more than 12,000 filters all over the world and are considered the market leader within our range of products.
Around 65 people work at Hydrotech, and we are proud to say that all of our filters are of Swedish origin and manufactured in our own workshop in Vellinge.
