Sepra was a pioneer in bringing membrane separation technologies to Italy. The first agreement as Italian distributor dates back to 1983 with the US manufacturer Osmonics, then leader in the market of spiral wound membranes.

Between 1983 and 1993, Sepra developed semi-engineered products to meet new demands of Italian industries, becoming a distributor of a French manufacturer of ceramic tubular membrane Tami Industries.

Between 1993 and 2000 new products were added, including UV sterilizers and a line of injectors / nozzles for liquid/liquid or gas / liquid mixing systems.

The new facility in Cesano Maderno is opened in 2000, starting a new development phase. Between 2000 and 2002, oil separation product line is added in order to achieve greater capacity for the oily waste water treatment. In addition, standard systems are introduced for lab cross flow filtration membrane pilot plants.

In 2003 Sepra adds new product lines and became one of the leaders in terms of cross flow filtration membrane variety. Polymeric tubular membranes for high solids concentration fluid filtration are also added.

Between 2002 and 2004, Sepra incorporates Ozonis S.r.l., developing its own home-made ozone generator line. Ozonis is then transformed into a Sepra division

In 2008, new concept of membrane bioreactor MBR is conceived and patented by combining injector aeration system with tubular membranes for maximum energy efficiency on high-solid content waste water.

In 2010, the majority stake in the company T.A. S.r.l., a workshop specialized in the construction of pilot plants and membrane separation plants, is acquired.

In 2011, a line of modules made of hollow fiber membranes was introduced for tertiary filtration with submerged or external MBR systems

In 2014 Sepra invests in the creation of new shop and office in Montecchio, allowing it to consolidate two owned locations in the most productive areas of North Italy.

In 2016, thanks to partnership with several O&M, Sepra acquires easier access to the rental of large units for new applications test on industrial scale.

In 2018 Sepra further expand its offer of fluid handling components with a new line of filtration cartridges.

In 2020 the e-commerce web site www.filterandmembrane.com becomes fully
