The project
Medeina Engineering and Porto Sudeste are pioneering new sustainable
water management practices at the Itaguaí Port Complex
Medeina Engineering and Porto Sudeste are pioneering new sustainable water management practices at the Itaguaí Port Complex. By reducing the elongated dewatering times of local silty sediment flows, this project seeks to improve treatment and recuperation of rainwater on-site. To accomplish this, Medeina and PortoSudeste introduce aquatic worms to enable rapid water separation from the sediment matrix, optimizing the settling time of the remaining fines thereafter. Committed to SDG6 of the United Nations Agenda 2030, this project is set to improve rainwater reuse, significantly reducing groundwater dependency for internal port activities and enhancing operational sustainability.
Goals
- To optimize the water recuperation process, shortening water separation and therefore optimizing fine particle settling time
- To achieve higher efficiency in water reuse for port maintenance and operations
Our services
- Fast dewatering
- Water recuperation
Our tools
Our innovative use of natural agents in the Rainwater Treatment and Reuse Station will not only improve water clarity but also accelerate the dewatering of bottom sediments, facilitating their removal from the treatment plant. This translates in the deployment of a combination of aquatic worms during the initial settling phase, when the sediment bed is still an aqueous medium, and the introduction of local earthworms in subsequent stages. This way, earthworms complement the overall dewatering strategy and contribute to enhanced efficiency in sediment volume reduction.
Our process
Medeina Engineering’s expertise guides the project from design through execution, introducing a tailored blend of worms at strategic phases to maximize treatment efficiency. This process reflects a synergy of engineering precision and natural processes.
The outcome
The collaboration is set to redefine water treatment and reuse at Porto Sudeste, delivering marked improvements in sustainability and operational efficiency. By leveraging nature-based solutions, this project underscores Porto Sudeste’s leadership in environmental stewardship and aligns with global sustainability goals.
