River Cleaning System
Our project consists of a series of floating devices, which are positioned diagonally along the river, intercept the plastic waste and transport it to the side of the river, in a special storage area.
Why revolutionize everything?
The devices are 100% scalable. Depending on the size of the river, the strength of the current and other eventualities, it is possible to study the correct sizing for the best possible performance. We have studied its structure to make it solid and to be able to come into contact with boats of all types.
The structure of the River Cleaning System devices allows it to divert waste by transferring it from one device to another, until it reaches the storage area beside the river. Its constant and incessant functionality allows it to intercept waste in full efficiency and safety.
The River Cleaning System collects energy directly from the river current. It does not need auxiliary power, and does not produce any type of waste. It is designed to have zero impact on the ecosystem. It only does good!
The anchoring system and the structure of the River Cleaning System allow it to behave exactly as if they were a series of normal buoys. In this way, when they come into contact with the boats they let themselves be dragged along the edges, and then return to the starting position.
River Cleaning System vs Other Systems
There are several solutions that involve the use of fixed or mobile barriers, but compared to these River Cleaning offers better solutions:
- compared to a rigid barrier it does not risk breaking, nor being submerged by a greater flow of water;
- it does not lose power with higher flows, since the greater the thrust of the water the greater the rotation and consequently the yield;
- does not risk the jams of the typical collection ships;
- the width of the river is not a problem as it is modular;
- it is truly scalable on any river, and can be used anywhere;
- does not require staff;
- any faults are limited to the individual units, and for this reason, in the event of damage, it is very easy and inexpensive to restore total efficiency
We are currently in the prototype testing phase and with these, many problems have already been solved
Resistance and maintenance
What debris can the devices handle?
The device intercepts most of the floating debris, so as to prevent it from ending up in the seas. The main intercepted debris are disposable plastics and packaging.
How does it behave with large debris (ex: branches, logs)?
The system deals with the contact with large debris as with boats, the single devices move, allowing the floating body to continue.
What happens in the event of a quick impact with a boat?
The anchoring of the devices is designed to detach in the event of a strong impact, to safeguard the safety of people on board the boat.
What kind of maintenance will it need?
The system is designed to require the least possible maintenance, in case of failures or blocks these will probably be limited to the single rotating units.
Anchoring and Arrangement
Do the devices rotate on themselves, or lose their positions?
No, the devices are anchored to the rope in a frontal position, the current keeps them naturally parallel to the watercourse and keeps them in the right position.
How do they keep on the axis?
Depending on the initial installation, they are arranged and calibrated so as to reposition themselves on the axis even if subject to shocks or variations in the intensity of the current.
How do they maintain the right position and distance despite the changes in the river level and its intensity?
The ropes to which they are anchored, have sufficient length to allow the devices to remain functioning in a wide range of river level variation. When the water level changes, the angle with which the ropes connect to the units will also vary.
How can they be anchored to the river bed?
They can be anchored to a weight, to a stake or fixed previously to a single rope which is then laid on the river bed.
How does an installation vary depending on the size of the watercourse?
In the case of large water courses, or with particular characteristics, the modular system allows more consecutive lines to be arranged, the devices can also have very different dimensions, in order to adapt to the best environment and plant requirements.
How far should the devices be arranged from one another?
Currently we think about 70 cm from each other, but we are in the process of continuous improvement of the project.
Which systems can be used to give the rotary movement to the devices?
The possible systems are many, the present solution includes blades that transmit the rotary movement to an external rack, other solutions can include self-propelled side blades, or up to an external power supply in case of particular needs.
How much can the cost of the single device be?
If industrialized and mass-produced, the cost can be extremely reduced.
What kind of collection point can be there?
You can arrange a standard collection point that contains the waste and can then be picked up and replaced comfortably. Alternatively, a separator system can be installed which divides the waste at the moment.
What materials are collected?
Mainly floating plastics, polystyrene, wood, leaves, etc.
Can problems occur with varying water levels and device positions?
During the positioning the possible variation of the current and the river level is calculated.
