HYDROSPHERE ASSOCIATION TECHNICAL SOLUTIONS for the active removal of macro- and microplastics from the waters.
Two are the polluting elements that Hydrosphere Association wants to remove from the Earth’s waters:
1 – macroplastic litter (objects greater than 5 mm) and
2 – microplastic debris (objects smaller than 5 mm)
Clearly, the dimensions of these elements involve two different ways of tackling the problem, and two different solutions:
- Macroplastics removal: The solution of the Hydrosphere Association team involves the use of fishing boats and native fishermen in the area concerned, as well as a net specifically designed to capture and remove from water the plastic litter greater than 6 cm, excluding fishes, up to three meters depth.
Water volume cleaning capacity of the 100m size net: up to 900 m³/s (depending on the net hight)
- Microplastic filtering: The Hydrosphere Association team has devised a special filtering machine, to be applied on ships and on the banks of rivers. The filters can filter up to 3 meters depth. Depending on the size of the rivers, the filters sizes can vary from 1 m to 3 m depth.
The filtering machine is composed of three sections:
a pneumatic arm for supporting the filtering unit in the water;
the filtering unit with a collection device for captured particles;
a shaped hull to divert objects greater than 6 cm.
Filtering capacity of the larger version: 140 m³/s; mesh sizes up to US standard 20 (0.841 mm)
