Abstract:

Each reverse osmosis device can generate 60t/h demineralized water,but it needs to discharge 20t/h concentrated brine. In order to reduce discharge quantity of waste water,the equipment is modified,so that half of the concentrated brine can return to the feeding water of the reverse osmosis device.With this improved reverse osmosis process,the plant is running stably,the discharged water meets national standard,and 20t/h ground water can be saved.It’s an energy-saving and emission-reduction,environmental friendly and efficient process.
