| Title | Process for the recovery of high purity salts - sodium chloride and sodium sulphate from crudes (sulphate-rich brine) |
| Knowhow is available for | A process relating to the recovery of high purity salt (NaCl) and sodium sulphate (Na2SO4.10H2O) from crudes |
| Summary | The leather industry has received criticism on environmental grounds. Due to high pollutant loading, this tannery effluent is not suitable for direct discharge and requires downstream treatment / processing.
Similarly, composition of salt brine of Rajasthan is typical and different with sea brine as it does not have much calcium and Magnesium impurities and contains high level of sulphate impurities in the brine as Sodium Sulphate. The salt produced is highly contaminated with sodium sulfate and not suitable even for edible as well as industrial purpose.
The process relates to the recovery of high purity salt (NaCl) and sodium sulphate (Na2SO4.10H2O) from crudes such as solid waste from tannery effluents and common salt produced from Rajasthan lakes (India) containing sodium sulphate. |
