Smart buoys are installed to combat algae on the Tietê River in Sabino 14 smart buoys were installed this Monday (20) in a branch of the Tietê River, in Sabino (SP). The São Paulo Government's pilot project uses ultrasound waves to reduce the proliferation of algae and improve bathing conditions at Praia Municipal, one of the region's main tourist attractions. The project covers an area of ??approximately 960 thousand square meters, the equivalent of more than 130 football fields. The equipment was installed in Córrego do Esgotão, a stretch that directly influences the quality of the beach's water. ?

The technology reduces the formation of the so-called "green cream" without using chemicals and without causing impacts to fauna, flora or other aquatic organisms. "The function of the buoys is to control the growth of algae. They emit ultrasound waves and then we no longer have the presence of algae, which produce toxins and prevent the use of water. It is very important for tourism, because the entire region uses the beaches of Sabino for leisure. The objective is to recover the use of the river", said the director-president of Cetesb, Thomaz Toledo, on TV TEM. Cetesb states that, in around 60 days, it will be possible to see the first results from the buoys in Sabino TV TEM/Reproduction "As soon as they are turned on, the system starts working and, in around 60 days, we should see the first results", he said. In addition to installing the buoys, the population will also be able to monitor the bathing conditions of Praia Municipal de Sabino through the Cetesb app. Smart buoys are installed to combat algae proliferation in a branch of the Tietê River in Sabino TV TEM/Reproduction
