Reducing salinity in the pickle-tanning process Part 1 of 2

摘要

The following paper describes a series of structured investigations with the objective of eliminating common salt from the pickle-chrome tanning process. As pressures to reduce salinity in waste waters increase, the findings and descriptions provide a detailed insight into the technical issues that face tanners who seek to achieve this target. On a global scale, salinity represents a major environmental problem. The availability of quality Water is diminishing, and cause for widespread concern. Contamination of surface waters and the aquifer are increasing in many areas, rendering water that was previously available unsuitable for either consumption or land irrigation.
