Surface treatments for medical parts


An important multinational company in the medical sector has chosen SAITA for the installation of a new zero liquid discharge water treatment system for vibrofinishing (tumbling), cleaning and anodizing of : aluminum, titanium and stainless steel parts. Following the successful outcome of laboratory tests, two types of zero discharge treatments were installed: The first is a vacuum evaporator mod. EV30SD, with a capacity of 700 l/day, made of Superduplex SAF2507, for the treatment and recycling of the water produced by the anodizing and cleaning lines. While for the vibrofinishing wastewater, a chemical-physical batch plant was installed complete with an automatic powder dosing unit and a centrifuge for the dehydration of the sludge. The purified water obtained from both processes is reused within the company’s production processes.

Technical characteristics:
Heat pump vacuum evaporator 700 lt/day made in SAF2507
Batch chemical-physical treatment plant for vibrofinishing waste water
Automatic powder dosing unit for flocculant reagent
Centrifuge for sludge dehydration


ZLD zero liquid discharge
Closed loop recirculation of treated water
Reduction of liquid disposal costs
Remote control via ethernet – Industry 4.0
