Cleaning up wastewater from viscose fibre manufacture by isolating local streams
- 20 Downloads
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.
