Dear Reader
Is there anyone out there who knows or has a cost-effective alternative to the evaporation of excess water from an ammonium sulphate solution?
The requirement is to control the concentration of ammonium sulphate at 40% +/- 2%. by removing around 5% excess water produced by the downstream process and wash water collection.
I think the cost-effective evaporation of water from Ammonium sulphate solution depends on the volume to be used. For low-volume say up to 5 liters, you may choose vacuum evaporation using a rotary vacuum evaporator and for large volumes beyond 15 liters, you may use RO (Reverse Osmosis) filtration. There are other methods using thin film evaporators, falling film evaporators, etc. The use of various techniques depends on volume and frequency of usage.
