Working for over 35 years through laboratory tests, pilot scale tests and industrial plants, Hydro Air Research Italia has acquired extensive experience and know-how in various processes and application fields. Industrial process applications include biotechnology and pharmaceuticals, as well as applications in the food and dairy sectors, and in the chemical and petrochemical sector.
Hydro Air Research Italia designs and supplies complete membrane plants: from the dimensioning, through the implementation, up to the starting. Membrane technology can be used in a wide range of processes. Thanks to its experience, Hydro Air Research Italia covers all the different membrane processes: from microfiltration and ultrafiltration through to nanofiltration and reverse osmosis for electrodialysis.
Depending on the purpose of the separation, it is possible to use different types of membranes, characterised by different materials of construction, configuration and selectivity: organic membranes and inorganic membranes, coiled spiral and hollow fibre membranes, ceramic membranes.
The selection of membranes is carried out based on the application and the process requirements.
Hydro Air Research Italia specialists work with the end user to meet the widest range of requirements in terms of application, volume and regulations, adapting the system to customer needs.
Membrane technology offers several advantages over other available separation methods, including:
The main applications in the chemical field are: polymer concentration/recovery; brine purification and recovery; catalysts and solvents recovery; dialysis and solvent replacement; acid concentration / purification; glycerine purification; pesticide removal from effluents.
The demand for increasingly higher purity, especially in the food and dairy sector, can be met with membrane technologies. The membranes can easily concentrate and remove impurities that are difficult to separate with conventional separation technologies.
Applications in the petrochemical field include the treatment of oily wastes, the reuse of produced water, the treatment of injection water (sea water and low salinity water) and the removal of sulphates.
Hydro Air Research Italia's systems work successfully and at advantageous costs on downstream processing and in particular on processes for the extraction, purification and concentration of antibiotics and the extraction of biological active ingredients from fermentation broths.
Hydro Air Research Italia has developed and patented systems for treating landfill leachate. The plants built are turnkey, efficient, reliable and economically sustainable.
Hydro Air Research Italia provides engineering solutions for the removal and recovery of emulsions, surfactants, pollutants in the field of cosmetics, detergents, laundry and metallurgy.
There are enormous potential benefits in the treatment of effluents from industrial dry cleaners and wastewater from textile industries using membranes. Applications concern color recovery and removal processes.
Hydro Air Research Italia systems can treat wastewater characterized by a very high level of pollutants and solve complex removal problems to discharge in accordance with current regulations, or for an internal reuse of water.
Applications in industrial processes include both upstream and downstream fermentation in bioethanol production, biodiesel, biodegradable plastics and enzymatic reactions.
