TECN.A. builds hollow fiber membrane ULTRAFILTRATION SYSTEMS for the filtration of primary waters (well, river, etc.).
Compared to traditional systems with sand filters, which have the exclusive function of removing the suspended collodial particles function, ULTRAFILTRATION SYSTEMS represent the ideal process to satisfy the requirements of absolute and sterilizing filtration, effectively eliminating even the bacteria (Escherichia coli, Aeromonas spp., Salmonella, V.cholerae, etc.) and pathogens (Cryptosporidium, Giardia, etc.) that can be found in the water.
Depending on the chemical and physical characteristics of the water, the ultrafiltration process can be applied directly or after a preliminary treatment by sand filtration.
Ultrafiltration is also the ideal pre-treatment to reduce the SDI value of water entering Reverse Osmosis plants.
