What is the final treatment for the concentrated water from reverse osmosis, and what should be done to ensure that the 30% -40% concentrated water discharged from RO reverse osmosis pure water equipment is environmentally friendly and effectively utilized

Concentrated water is the high concentration salt water separated from tap water by reverse osmosis pure water equipment. As long as reverse osmosis filtration is used, concentrated water will be produced, and it is also an irreversible problem. So the discharge of concentrated water is not only detrimental to environmental requirements but also a waste of production water costs. So, is there a feasible treatment plan for these RO concentrated water? Where can the treated water be used?

If there is a treatment plan, the concentrated water recovery rate can reach about 65%, and it can be returned to the on-site reverse osmosis pure water equipment as tap water, truly achieving the effect of energy conservation and emission reduction.

The ultimate treatment of reverse osmosis concentrated water is to create a RO reverse osmosis concentrated water treatment equipment to filter out these RO concentrated water. The RO concentrated water is reused in the equipment for treatment, and 60% -70% of the treated water will be converted into tap water and returned to the reverse osmosis pure water equipment for use as tap water. The remaining 30% -40% of the secondary concentrated water is not meaningful for recycling, as the salt content is too high and can be used as flushing water in production. The entire treatment process is physical filtration without adding any additives. The RO reverse osmosis concentrated water recovery equipment is currently an ideal equipment for treating RO concentrated water.

In fact, the concentration of reverse osmosis water is only slightly higher in salt content, and it is cleaner than tap water because the concentrated water has been filtered by the sand and carbon pretreatment system, removing impurities, sand, rust, collagen, and visible substances from tap water.
