“…Other way of utilization of the used liming solution is just to process it before cleaning getting chemicals, which can be reused for various purposes as well as in leather industry. The study of Venkatakrishnan et al (2019) depicts an innovative approach to reduce pollutant and recover calcite (CaCO3) from theliming process waste by carbon dioxide (CO2) fixation. The results indicated rover >95% of calcite (CaCO3) recovery from synthetic lime wastewater followed by 85-90% from lime sludge product and relime sludge product under optimized conditions.…”

Results of the investigation of hide liming process wastewater treatment by carbon dioxide are presented in a paper. Comparison of the wastewater characteristics before and after the treatment by carbon dioxide was carried out. It was attempted to regenerate sodium sulphide using three different solutions: 10% solution of sodium carbonate and 5% or 10% solution of sodium hydroxide. The kinetic of sodium sulphide concentration, general alkalinity and pH was established. The solutions with the regenerated sodium sulphide were explored for unhairing of hide. The solution of 10% sodium hydroxide with regenerated sulphides was the mostly suitable for this aim. The properties of unhaired pelt were determined and assessed.
