The reverse osmosis pure water equipment will produce a certain amount of concentrated water during operation. Don't think it is useless. In fact, its role is very significant and it is very helpful for environmental protection. How much concentrated water is suitable in the middle?

RO reverse osmosis pure water equipment concentrated water refers to the concentrated water discharged by reverse osmosis during the entire process of producing pure water or double distilled water. The reuse of concentrated water can not only improve the utilization rate of reverse osmosis water, but also achieve the goal of energy conservation and consumption reduction.

The 2-ton system software generally has a utilization rate of around 50%, and the ratio of purified water and concentrated water is 1:1. Softening water treatment is the process of removing the majority of chlorite from water, which undergoes reverse osmosis (RO) membrane treatment. The portion of water that is treated is pure water, while the portion that cannot be treated is concentrated water. Pure water/Pure water+Concentrated water=Water production rate of reverse osmosis machine equipment (%).

Many companies use concentrated water for landscaping and daily life (non domestic water), but I understand that some companies return to their original reservoirs and then purchase them. Related to the amount of water, the key is to determine the oxidation-reduction potential of the final purified water, which should be below 10. Concentrated water should be discharged or reused with epoxy resin for desalination. The design scheme for pre desalination of industrial production RO (primary) is a two-stage process with a utilization rate of 75%. Most engineering design companies are like this. For the problem of RO concentrated water, there have already been very detailed discussion posts on community forums. The editor can search for it. There is already a comprehensive system of software, which is very worth learning and training. Generally speaking, RO concentrated water landscaping is not suitable due to its high salt content. Many companies in new projects use secondary RO concentrated water as a preparation for water treatment, filter softener tap water, which has good water quality and can save water.

The concentrated water regulating valve and the regulating valve behind the pump shall be adjusted in coordination with each other, and the following standards shall be considered: the working pressure of the system software shall not exceed the rated current, that is, the barometer in front of the membrane shall not exceed 0.1Mpa (0.5~0.8Mpa under normal conditions). The utilization rate of concentrated water in water purification equipment shall not exceed the range required by the system software for normal operation (50%). At any time, it is not necessary to completely close the concentrated water regulating valve. Otherwise, it will cause a sudden increase in the working pressure of the system software, leading to the destruction of machinery and equipment or seriously endangering the safety of operators.

The ratio of pure water to concentrated water is 3:1. For concentrated water, many enterprises consider using a multi substance filtration device as the softener tap water. If ion exchange method is used to solve concentrated water, the cost of economic development will increase, and the actual effect may not be good, as it will continue to cause recycled wastewater.
