1. A separating arrangement for a device for collecting liquid or solid waste material including oil or plastic waste material floating on or near a surface of a body of water, the separating arrangement comprising:
a first basin,
an opening arranged in the first basin,
a separating means,
a collector arrangement configured for collecting water and waste, and
a transfer arrangement configured for transferring the collected water and waste to the separating means, the transfer arrangement comprising a base pipe configured to extend from the collector arrangement to the opening and a pressure pipe for forcing a jet of water into the base pipe when the device is in use,
wherein the separating means is configured to separate at least a part of the waste from the water from the first basin,
wherein a width of the first basin is at least three times a diameter of the opening,
wherein the collector arrangement is a funnel comprising a hole in a bottom of the funnel,
wherein the transfer arrangement comprises a vertical suction pipe connected to the hole of the collector arrangement,
wherein the base pipe is connected to the suction pipe under the funnel, and the pressure pipe is configured to direct the jet of water towards a center of the base pipe in such a way that the moving water in the base pipe has a speed gradient and a direction of the jet of water is parallel to a longitudinal axis of the base pipe,
wherein the water coming from the transfer arrangement to the first basin from the opening is directed to the separating means, and
wherein the separating means has a first end and a second end, and the first end of the separating means is nearer to the opening than the second end of the separating means, and
the separating means comprises a conveyor belt arrangement, and the conveyor belt arrangement comprises a first conveyor belt and a second conveyor belt, and the second conveyor belt is inside the first conveyor belt.
