Algae are organisms which propagate under certain conditions, generally in stagnant water. In ponds, for instance, algae under unfavorable conditions, may multiply to such an extent that other plants and animals are ousted. Algae also occur to an increasing extent in seawater or brackish water, this frequently also being attributable to overfertilization. One favorite spot for such algae to settle is on ships' hulls which may, for instance, lead to increased fuel consumption. Algae are seen as well in cooling loops or cooling towers. In warmer areas of the world it is rather drastic, and a cooling tower can be very fast full of algae. Once this has happened it is very likely the algae are spread in the loop as well and start to form the feared biofouling in pipes and machines.
Merus is used with for this purpose special developed Bio Rings, in most cases with great success. In a lot of cases the need for adding biocide to the cooling water has been reduced drastically or even stopped entierly. There are numberous applications, in cooling towers, swimming pools, fountains, cooling loops, lakes and ponds. We even discuss now to reduce the growth of algae on ship hulls. Another issue Merus is discussing now are large-scale trials, such as in rivers or big lakes. Here we are searching for partners, to make a trail project in order to collect more data. In the case of open water, the advantage for the environment would be tremendous. Too much algae are reducing the oxygene in the water, which affects the marine life.
