Wastewater containing sodium sulfate and aluminum phosphate is concentrated using reverse osmosis membranes
Thread Content
The wastewater from the pharmaceutical factory’s production process contains sodium sulfate and aluminum phosphate at concentrations of about 5%. This wastewater is to be treated using plate-and-frame filters, followed by concentration through reverse osmosis membranes; after the volume of the concentrated liquid is reduced, it is then sent to an evaporator. The question now is regarding reverse osmosis: is concentration feasible? Then, what issues need to be considered during the design process? I would like to ask the more experienced colleagues for their advice
For those cases where reverse osmosis cannot achieve the desired concentration, our company’s product, electrodialysis, can bring the concentration up to 15%, thus helping to solve the problem. If you need this service, please contact me at 15088793370
Reverse osmosis is still not an easy option for this purpose. For sodium sulfate and aluminum phosphate, electrodialysis can be considered; it allows for concentration to around 15%, which is quite cost-effective. Add me – my profile picture shows how to contact me – and I’ll prepare a plan for you
Reverse osmosis can clog the membrane, which is a problem; electrodialysis can be used for concentration, with fresh water being reused and the concentrated water being evaporated
The service life of waste acid concentrated by reverse osmosis is relatively short; low-temperature non-metallic membrane distillation technology is used for the concentration of 18501003909
