Introducing the Duperon Harvest Rake
The Harvest Rake is an example of applying Duperon innovation to a unique need. It is specifically designed to manage high volumes of aquatic vegetation for algae harvesting and nutrient removal. It can also effectively remove large mats of long debris in open channel applications. The Harvest Rake offers a solution for sites that have side currents, backflow, or channel turbulence with the same flexibility, ease of operation, and simplicity expected from Duperon products.
- Intakes for rivers with strong side currents
- Estuary protection
- Fish farming
- Algae harvesting
- Post–treatment for algae harvesting
- Nitrogen and phosphorus removal
The Harvest Rake is ideal for open channel applications with debris that may be long, stringy, or matted in clumps, such as vegetation or rags. Front-clean, rear-return technology utilizes proven FlexLink™ technology to assure effective debris capture without entanglement or wrapping.
