For large-scale reverse osmosis equipment projects, three points depend on equipment and seven points on construction.No matter how well you buy the equipment, the construction team will still be in vain if you pull the crotch.Many people only stare at the equipment parameters, ignoring the construction process is the key to determining whether this system can run stably.

Do raw water testing before entering the market to avoid various follow-up problems
Reverse osmosis equipment is not bought back and can be used as soon as it is put on the ground.You have to figure out what's going on with your water first-how much TDS, how hard it is, whether there are heavy metals, and how the water temperature is.These data are not available, and the selection of the latter depends on guessing.Let me tell you, I can't tell you how many people really pay attention to this step. Anyway, in the cases I have seen, at least half of the engineering problems are caused by the failure of the early testing or the inability to do it.To put it bluntly, the raw water data is the foundation of the construction. The foundation is crooked, and everything on it is useless.
From pipeline welding to equipment installation, take a closer look at the construction process
There is nothing fancy about this part, it just depends on the craftsmanship and sense of responsibility of the construction team.Share with you the situation of a previous customer.In August 2025. a chemical park in Baoji processed 80 tons of reverse osmosis equipment per day. In order to catch up with the construction period, the 316L pipe was replaced by 304. and it was not passivated after welding.After less than three months of operation, the pipeline on the concentrated water side was corroded and perforated, and the entire line was discontinued for maintenance for eleven days.The loss of production and the penalty for breach of contract of the order are enough for the construction party to drink a pot.So you have to look at the comparison of the engineering landing capabilities of large-scale industrial reverse osmosis equipment manufacturers. Don't just look at who has a low quotation, it depends on whose construction team can handle it.For our DIEN water treatment projects, pipeline welding is all licensed and on-duty. Passivation after welding is a standard process, not an option.

The details are not controlled in place, and the progress of commissioning and acceptance is affected
Commissioning and acceptance is the last hurdle of the entire project.Pressure testing, water quality testing, and joint adjustment of automatic control systems have to be reworked in any link that goes wrong.Last year, in a food factory in Xianyang, the conductivity of the water produced during the commissioning and acceptance of the reverse osmosis equipment exceeded the standard. Their own people checked for three days and did not find out. Finally, they found us. The technicians went over and took a look-the O-ring was reversed, the seal was not strict, and the concentrated water was mixed into the production water.The matter of an O-ring delayed the construction period for a whole week.
You have to figure out how Xi'an industrial reverse osmosis equipment is selected according to the water quality of raw water. It is not only a matter of the selection stage, but the construction stage must also be matched with the raw water data, otherwise the previous selection will be correct, and the construction will be changed for you, which is tantamount to a blank choice.
