Harsonic® is the leading international manufacturer of innovative ultrasonic algae control systems without chemicals. We control the growth of algae and reduce the formation of biofilm and some other micro-organisms in every kind of waterstorage. By means of ultrasound vibrations we prevent that barnacles, algae, chalk, etc … can attach to any object submerged in water, especially for industrial applications. We can clean tubes, boat-hulls, cooling-towers, all kinds of liquid storage also diesel tanks and many more. Further on we reduce algae in all kinds off waterstorage. Many of the traditional methods to fight algae are either insufficient, environmentally unfriendly, or all of these. We remove the bio-film very fast and by doing so we prevent a lot of problems.
