Bilfinger Water Technologies, a success born in 1923
Diemme's story started in 1923, when the founder, Mr. Alfredo Melandri, planned and realized the first machines for mechanically pressing grapes. During the first decades of the last century, the main market of the company was the oenological industry and we developed innovative technologies for our wine-making customers.
During the 60s, thanks to the intuition of Mr. Primo Melandri, Alfredo's son, the filtration technologies that had been applied exclusively to the oenological sector up until then, were expanded to other industrial processes. Europe was facing a period of remarkable economical growth and the growing demand for filters within the industrial sector could only be satisfied with the establishment of a new division within the company; this section, was specialized in solid-liquid separation technology and was equipped with its own technical, commercial and production structures.
In the early 1970s, DIEMME Filtration was therefore reorganized and restructured in order to become a true multi-business company. Two divisions in the company were set up: the Filter Division and the Oenology Division; each quickly achieved industry leadership in their respective sectors, both nationally and internationally.
In 2011 the filter division was parceled out from DIEMME SPA and bought by PASSAVANT GEIGER GmbH, part of Bilfinger SE.
The company born by the filter division spin-off, named DIEMME FILTRATION, becomes part of PASSAVANT GEIGER GmbH, set in the Bilfinger business unit, Facility Service, specialized in environmental technologies and water treatment.
After a reorganisation and rebranding of the Bilfinger Group, Diemme Filtration change its company name on the 1st of March 2013 to Bilfinger Water Technologies srl and become part of the Bilfinger Water Technologies Group.
