Defeating blue-green algae: Meet the advanced MegaShark
SUSTAINABILITY – RanMarine’s aqua drones help clean the water by combating plastics and (blue-green) algae, which plague Dutch waters every summer.
Nothing beats a dip in natural swimming water during a hot summer day, right? But every year, the same question arises again: Is the water safe for swimming, or will these awful blue-green algae prevent us from entering the water? With the WasteShark and MegaShark, RanMarine not only removes plastic waste and unwanted algae. “We are now working hard on developing an advanced MegaShark that can target the harmful and annoying blue-green algae as well,” says Richard Hardiman, CEO of the Rotterdam-based company.
In the ongoing battle against water pollution, RanMarine is making waves with its innovative water drone technology. The company is tackling the global issue of water pollution with the WasteShark and the Mega Shark: high-tech devices that glide through the water, collecting pollutants. “You can compare it to an autonomous vacuum cleaner, but instead of vacuuming your lounge, they vacuum the top thirty centimeters of waterways”, explains Hardiman. The drones are equipped with sensors and cameras and can navigate complex waterways.
Natural waters face a big problem nowadays: algal blooms. The consequences of excessive algae range from unattractive appearance and unpleasant odors – bad for tourism and overall well-being – to severe disruptions in aquatic ecosystems by depleting oxygen levels and blocking sunlight, damaging plants, and harming the fish. “The blooms are fueled by excessive nutrient runoff of farmer lands and profit from climate change. As temperatures rise and the population grows, we must feed more people. That means more farming and more fertilizers. I foresee that algae will become a huge problem in the future”, Hardiman explains.
