Extension of Port of Santos
The growth of the Brazilian participation in the international trade market has generated a demand for modern port terminals with larger capacity. Although the Port of Santos is considered the largest port in Latin America and one of the 50 largest ports in the world, the Brazilian port terminal company Embraport had experienced a consistent increase in cargo handling during the past years and was operating very close to its maximum capacity. Thus, Embraport decided to improve the port infrastructure and build the largest private multimodal terminal in Brazil.
Located along the southeast coast of Brazil, the Port of Santos was a challenge due to its proximity to an important environmental protection area. The dredging of 680.000 m3 of sludge from the channel needed to be done according to all the environmental rules and the sludge needed to have the highest level of dewatering as possible in order to reduce the environmental impact and storage area.
Environmentally friendly solution combining cost benefit and reliable service
Due to the area availability, CAPEX requirements and environmental restrictions, Embraport chose Allonda, a Brazilian engineering and service company working with geotubes, as the best option for the project. Allonda worked together with Kemira to find the best performing product for sludge dewatering into the geotubes, as well as the best way to apply it in order to improve the dewatering results.
Kemira’s Superfloc 8566, an anionic polyacrylamide, was selected as its high performance and complete automated system had been built to apply the product according to sludge characteristics. Combined with high level sales and technical expertise, this resulted in a fast, easy and reliable product process as well as performance, saving the customer money as well as lowering the environmental impact.
