GALIGANI FILTRI, 50 years dedicated to industrial filtration
Galigani Filtri Srl is a company operating in the sector of “solid-liquid” separation (industrial filtration), both in Italy and around the world. The firm specialises in the design and construction of filter presses and pistonoperated
alternative pumps for small, medium and large deliveries.
The first filter presses were designed and constructed for the decolourisation, demargarinisation and brightening of oils used in foodstuffs, for the major Italian refineries of the 1950s.
Starting in 1973, with the rise in problems of environmental pollution and the effects of industrial effluents, Galigani Filtri began designing and constructing machines for the dehydration of industrial and civil sludge coming from depuration plants.
The year 1984 saw the company construct its first completely automated machines for the winterisation of rectified seed and olive oils (600 m² each).
The same year, Galigani Filtri produced the new, entirely automatic “Matchless” filters, which were equipped with a device for shaking plate against plate and represented the most highly evolved automation of the functioning of a filter press.
In 1987, the company designed and constructed the “Simultaneous” line of filters, which were specially designed for rapid filtration of inert materials, where the
volume of solids is preponderant when compared to the liquid phase. The success of these units was in part due to the use of a PLC for the management both of the filter and of the automatic operations of the entire system.
In 1990, the company began designing and installing closed-circuit treatment and filtration systems, which were completely automatic and designed to recycle the
reflux waters from the marble and granite-producing industry.
Galigani Filtri works in collaboration with its clients to carry out tests on slurries, the selection of treatments for filtration purposes, the selection of the machines required and the choice of dimensions of the machinery.
