AL-2 Teknik, founded in 1994, initially producing belt filters to fish farms for screening discharge water. However, it became clear that the extremely efficient and well-functioning AL-2 Belt Filter, with some small changes, could be used in many other places including the food industry. The first AL-2 Belt Filter for industrial use was sold in 1994 for filtering of carrot peel from water. Since then, the development has been strong and today the BELT FILTER is used in the food industry, slaughterhouses, treatment plants, district heating plants and many others.
