THE OFFSHORE GULFWEED DISPOSER BOAT

L'invention concerne la solution pour se débarrasser des algues sargasses récupérées en pleine mer. Il s'agit de récupérer les algues en pleine mer : le moyen le plus adéquate est le pompage ; ce procédé suppose qu'un travail de collecte est réalisé en amont par un tiers. Les algues sont par exemple déjà emprisonnées dans un barrage flottant. Une pompe aspirante puissante recueille les algues mêlées à une certaine quantité d'eau et les injecte directement dans le broyeur à gros débit (5 à 10 m3 /heure). Le mélange eau sargasse est nécessaire pour plus de fluidité ; autrement on obtient une pate de sargasse plus difficile à écouler. Apres broyage on obtient une bouillie d'algue qui sera envoyée vers une barge. Cette bouillie coule inévitablement une fois rejetée à l'eau. Ce dispositif sera particulièrement utilisé en cas de récupération des algues par des industriels, car si le poids ne bouge pas, le volume s'en trouve considérablement réduit. Cette bouillie pourra servir de nourriture à ...

WATER TREATMENT SYSTEM AND METHOD

A method of handling grey water and optionally at least a portion of the black water for disposal from vehicles such as boats, recreational vehicles or rural dwellings such as cottages, camps and the like, not having direct access to sewer systems, involves the treatment of such waste water with ozone. A batch system is used whereby a predetermined quantity of water to be treated is captured in a treatment tank. A circulating pump withdraws water from the tank and pushes the water along a treatment conduit, the conduit containing an ozone/water mixer and returns the water to the treatment tank. The treatment conduit has a discharge valve that is maintained in a closed position for a selected period of time. Ozone is fed to the ozone/water mixer from an ozone generator which is advantageously fitted with an air pump to pressurize the feed gas. After the selected treatment time, the batch is discharged to waste through the discharge valve. Advantageously, the ozone generator can also be used ...
