Galigani Filtri SRL

Galigani Filtri Srl, established in 1958 and headquartered in Monteriggioni near Siena, Italy, manufactures solid-liquid separation equipment with over 3,000 systems deployed across five continents. The company holds TUV SUD ISO 9001 certification and operates an on-site laboratory where technicians conduct filtration tests to determine optimal filter sizing parameters for each application. Galigani's core product line centers on filter presses for industrial sludge dewatering, offered in configurations ranging from manually operated units to fully automated models with PLC control and remote tele-assistance. Named filter press series include QUICKDRY, SIMULTANEOUS, MATCHLESS, and CLEARNESS, alongside DIAPHRAGM membrane filter presses that achieve higher dryness in cake output. Beyond filter presses, the company produces the FEEDFILTER combined feeding-and-filtration unit, PAPERPRESS paper-based filtration systems, DIATOM diatomaceous earth filters, WINTERSEI and WINTERAIDS cold-season filtration products, and HOTFILTER hot filtration systems. Feeding pumps are available in piston and piston-membrane configurations. The filtration process captures particles down to one-thousandth of a millimeter using synthetic filter cloths or filtering carton pads, producing compacted sludge with a minimum 30% dry solids content compared to roughly 5-6% achievable by truck extraction. Galigani serves the food, chemical, pharmaceutical, and environmental sectors, with typical installations including filter presses paired with elevator conveyor belts, container discharge systems, big-bag discharge, and truck-mounted configurations.
