This solution brings to the market a unique and innovative patented technology to collect all types of floating waste. These ships are made of a catamaran hull in which the bottom is closed providing a channel within the boat. There is a turbine creating a suction flow pulling large amounts of polluted waters inside. Then a filtering mesh stops all solid waste and lifts it up to discharge it on deck. If there were oil spilled, the hydrocarbons being lighter than water are floating, they will go past the filtering mesh and will be pulled inside a separation and storage tank for oil. Only clean water will be flushed out of the vessel. The Double Flow technology allows the simultaneous collecting of both solid and liquid floating waste.
