ARC

AUTOMATIC RIVER CLEANER

Marine Debris levels in our oceans are increasing rapidly and the only real way to effectively stop it is to collect it before it gets out there.  Hence we are developing a 24/7 collection device for Australian Rivers that not only collects the debris, it lifts it out of the water and places it in a skip bin ready for removal.

Our first Automatic River Cleaner (ARC) is in the water undergoing sea trials.  The device uses both hydro and solar power to turn a conveyor belt that will lift the debris up out of the water and place it into a skip bin ready for removal.  The image here is of the prototype unit which is being added to slowly and we will continue to update the page here as we develop this new device.

As the tide runs out, the wheel will free flow and that drives the conveyor belt.  Once on site out in the Port of Brisbane there will be two debris booms coming off the front of the conveyor which will direct the debris to the belt.  It will also have a separate pontoon with a skip bin at the rear for the debris to land in that we can tow away for emptying.

Soon it will have a series of solar panels on the roof that will be used to power a water pump to allow the wheel to turn even when there is no water flow.  We have found that the biggest issue with previous collection devices is that during the last hour of the tide, the devices have not cleared the remaining debris that comes to it and hence the area around the device is usually dirtire than the rest of the river.  We need to clear all the debris before the tide turns and hence the waterwheel will continue to operate to e nsure this derbis is cleared.  It will however turn off when the tide is fully outgoing, saving power from our battery bank.

The biggest advantage of this device is that in times of rainfall events, the river runs faster and with more debris.  As the river runs faster, the conveyor will too run faster and collect debris quicker.

If you feel your local river could do with one of these devices, get your local government to contact us either by email info@oceancrusaders.org or phone 0447 TURTLE (887 853)

This first prototype has been funded through grants from IFM Investors and Suez with assistance from the Port or Brisbane, Scallywag Fabrications and Matt Pilecki.  Engineering was completed by RDT Engineering Brisbane.
