Desalination

Seawater filtration is a crucial element in the desalination process, especially considering the complexity of impurities and salts in brackish water. In this context, SATI filters emerge as a reliable and durable solution due to their construction with high-quality materials such as Duplex, Super Duplex, and Titanium. These materials are critical to ensure corrosion and pressure resistance, which is necessary in demanding marine environments.

SATI filtration systems, with their advanced technology, provide effective filtration that ensures the removal of unwanted particles, sediment and contaminants in seawater. This process is essential to protect the components of desalination systems, such as osmotic membranes, from damage and contamination, thereby improving efficiency and extending the life of the devices.

The use of SATI filters in desalination offers several advantages. First, their robustness and durability help reduce maintenance and replacement costs, ensuring continuous and reliable operation of desalination systems. In addition, their ability to adapt to various operating conditions makes them suitable for a wide range of applications, from large industrial plants to more compact desalination systems for domestic use or in small coastal communities.

The use of SATI filtration systems also helps to improve the overall efficiency of desalination processes, reducing downtime and optimizing the performance of water treatment systems. This translates into increased production of high-quality drinking water, which is crucial for meeting the water needs of coastal communities and arid regions, where desalination is critical for water supply.

In conclusion, the use of SATI filters made of Duplex, Super Duplex and Titanium in the seawater desalination industry is a reliable, efficient and sustainable solution for the production of drinking water from marine sources. These filters are a lasting investment in ensuring continuous and safe access to potable water in areas where water resources are limited or compromised by salinity.

Water filtration in the desalination industry plays a crucial role in the process of turning seawater into usable drinking water. Desalination, which involves various technologies such as reverse osmosis and evaporation, requires effective pre-filtration to remove impurities, salts and other substances in seawater to produce safe, potable water.

Filtration systems used in desalination face unique challenges related to the high concentrations of salts and suspended solids in seawater. Therefore, it is essential to use advanced and robust filtration technologies designed to withstand harsh marine environmental conditions and ensure reliable performance over time.

Case History

An important city in Southern Italy needs to produce drinking water starting from sea water. To ensure the required water supply, it is essential to create a desalination plant. The water to be desalination must be previously filtered from sand, algae and biological dirt before passing through the reverse osmosis stage.

sati per l'ambiente

For this success story, SATI deems it essential to use AISI 316L material for the filtration system, given that brackish water, with its high salinity, has a strong corrosive power. The system is divided into two filtration phases: the first, entrusted to five Vortex hydrocyclonic filters, aims to remove the sand; the second, however, includes four Rotor HP filters. The latter, thanks to the patented suction pad cleaning system, are able to effectively eliminate the colloidal dirt and algae present.

After pre-filtration carried out by SATI filters, the water is directed into a reverse osmosis system.
