All membranes can be assembled in a wide variety of constructions, using diverse support materials (ABS, PVC, polysulfone, stainless steel etc). In this way, the element becomes compatible with a wide variety of applications.

The functioning of MAZZEI injectors is based on the principle of creating a depression in an area of high liquid velocity. This is fed upstream of a tube section where speed increases and the gas is injected. High turbulence creates micro-bubbles, resulting in the obtainment very high gas/liquid mass transfer coefficients.

The MK-3E module is an EDI cell capable of producing demineralised water with a very high level of purity. The ions are removed by means of an ion exchange resin, which in turn is regenerated continuously by means of electric current. Interruptions of the process and regenerating chemicals are thus not necessary to restore functionality.

The 1U oil skimmer eliminates in a simple, rapid and reliable manner floating oil and fat on the surface of liquids of all types, such as lubro-refrigerating emulsions, cooling water, degreasing agents, wastewater etc contained in small tanks.

Many cartridges are portrayed as effective depth filters. However, in order to provide good depth filtering the cartridge must be capable of retaining contaminants through the entire cross section of the filter. To accomplish this, the density of the filter must increase progressively from the outer to the inner surface. This "graduated density" allows the larger particles to remain trapped close to the outer surface, while the smaller ones can penetrate the inner area and then remain locked at the centre of the filter. Otherwise, the filter would work only as a surface filter; the differential pressure would rapidly increase, immediately occluding the surface area and drastically reducing both the ability to retain dirt and the duration of the filter.

SEPRA PRETREAT is a range of cartridges very suitable for the removal of solids from  water to be supplied to reverse osmosis plants. Filtration takes place by means of a polypropylene pleated membrane with absolute filtration degree (beta = 5,000 => efficiency at the nominal filtration rating > 99.98%).

GEO series ozone generators are suitable for industrial applications. The GEO generators have been designed specifically to operate at low costs on ozone concentrations between 6 and 10% by weight, with pure oxygen feed, and between 2 and 3% by weight with air feed. The ozone is generated using a dehydrated gas that contains oxygen, which is fed through an electric discharge created between two electrodes. These electrodes are separated by a discharge space within which the gas flows. The discharge, known as the "corona discharge effect",causes the dissociation of some of the oxygen molecules necessary for the formation of ozone.

The GEO ozone generator, entirely produced in Italy, represents the most advanced technology dedicated to the generation of high concentration ozone with oxygen or dry air supply. The GEOMIX system is a complete ozonation system that incoporates GEO ozono generator and every accessory needed to dissolve ozone in water; everything is placed in a metal cabinet or skid mounted.

The OZONIS GEOmini-series ozone generators are suitable for small applications where a high degree of reliability, simple installation and compactness are required. The devices are air-cooled and include a flow meter for the measurement of gas flow rate, pressure regulator, automatic safety valve on the feed line and a dryer for input air. OZONIS generators require no maintenance and ensure maximum production stability and ozone concentration. They are equipped with an air-pretreatment system for maximum ease of use.
