ABOUT MYSELF
I am a professional chemical engineer. Since 1985 I have been dealing with reverse osmosis and water treatments. I started out my career as an employee and as of 1993 and currently I am a consultant.

 

MY ACTIVITY
I estimate, I design, I build, I install reverse osmosis units. I also start and run them in Italy and abroad.

 

REVERSE OSMOSIS
Nowadays reverse osmosis is one of the safest and most economical technologies in desalting waters of various origins.
Reverse osmosis technology uses the properties of membranes, namely the semi permeable membranes, which allow a portion of water from a solution to pass while salts are retained, concentrated and finally discharged.
Reverse osmosis units work on a continuous basis (i.e. a continuous feed flow enters the unit. It continuously separates on the membrane in a low salinity flow, or permeate, to be used, and in a high salinity flow, or reject, to be sent to the drain).

 

MEMBRANE SEPARATIONS
Various membranes are available on the market. They show different capabilities in removing substances from solutions. Depending on their characteristics we can mark reverse osmosis, nanofiltration, ultrafiltration and microfiltration.
Reverse osmosis membranes can effectively remove particles with molecular weights less than approx. 200 and/or with sizes less than approx. 0.001 micron (ions, viruses and bacteria).
Nanofiltration membranes can effectively remove particles with molecular weights ranging approx. from 200 to 10000 and/or with sizes ranging approx. from 0.001 to 0.01 micron (ions, micromolecules, viruses and bacteria).
Ultrafiltration membranes can effectively remove particles with molecular weights ranging approx. from 10000 to 100000 and/or with sizes ranging approx. from 0.01 to 0.1 micron (macromolecules, viruses and bacteria).
Microfiltration membranes can effectively remove particles with molecular weights ranging approx. from 100000 to 500000 and/or with sizes ranging approx. from 0.1 to 1 micron (microparticles).
Larger size particles can be effectively removed by means of standard mechanical filtration techniques.

 

APPLICATIONS
A proper use of membranes allows many important results in fluid treatments.
By means of membranes you can remove salts and many pollutants (if any) from waters of various origins. Product water can finally meet requirements for human use, for field irrigation, for cattle feed, for boiler feed, for steam generation, for critical industrial washing, for medical use, for production of a lot of industrial goods.
By means of membranes you can separate, purify and/or concentrate various fluids (while working at room temperature) to improve industrial processes.
By means of membranes you can control the analysis of waste waters before you discharge them. You can also recover from civil and/or industrial wastes clean water for its reuse and valuable products (if any).
Combined use of membranes and other technologies optimises the use of available resources aiming to the so-called zero discharge system.

 

MY OFFER
I offer high level consulting on reverse osmosis and water treatment to both Manufacturers and final Users in order to size, make and run their units. The offer includes problem solving, maintenance, teleassistance, updating of old units, assistance in purchasing spare parts and in contacting main world Suppliers.
