Clean to the last drop

One area many labs are looking at making some kind of saving is the supply and use of the water needed for the glazing process. This often unseen expense is addressed with the Euro Aquasave on show at the recent Optrafair.

The Euro Aquasave constantly clears and isolates the problematic plastic pieces using the very latest technologies, allowing clean recirculated water to be returned to the lens edging machine time and again. The separation process is achieved by a vortex in the self-cleaning separation unit that forces the clean water upward and the cleared fines down into the dirt pot. This process is progressive and clears more and more on each pass. The final step is to pass the water through a housing that contains a material called DFDM; this captures ultra-fines prior to the water being returned to the lens edging machine. The single stage clearance without discharge is simply impossible by filtration, hydrocyclone or centrifuge. The DFDM material will capture these minute particles during the processing of approximately 1,500 lenses. The tank sits within a frame and is filled with 40-50 litres of water. The system clears coarse, fine and ultra-fine plastic pieces and leaves clear recirculated water without any sign of white film.
