Cleaning up wastewater from viscose fibre manufacture by isolating local streams
In viscose fibre plants, it is recommended to localize the absorber solution from the carbon disulfide regeneration unit and route it to a unit for crystallization of sodium thiosulfate.
When there are no units for utilization of sodium thiosulfate in plants, or during the period of construction and start-up, it is recommended from the results of these studies to deliver the absorber solution containing sodium thiosulfate to biochemical clean-up together with farm and household wastewater.
