After doing this business for so many years, I am most afraid of hearing customers say, "You can recommend me something about the same."Almost?Xi'an, this water quality is similar to what I said?Groundwater is so hard that it can scale, and the salt content of brackish water is frighteningly high. If you take a set of general equipment, it will be useless within three months.The selection of reverse osmosis equipment in Xi'an is really not something that can be decided by just patting your head. It has to be based on your water quality, water consumption, and application scenarios.
Reverse osmosis equipment
Understand the water quality of raw water to facilitate accurate matching of equipment
Xi'an raw water is complicated and complicated, and it is simple and simple. There are just a few kinds-groundwater, tap water, and industrial wastewater.Groundwater is a big head, with high hardness, high sediment, and bitter saltiness. If you don't do pretreatment of this kind of water, you will directly go to reverse osmosis, that is, waiting for the membrane to be blocked.I have seen too many. The customer tried to save trouble and save softening and multi-media filtration. As a result, the membrane was blocked like a stone for three months, and the money for changing the membrane was several times more than it was saved.
Tap water is relatively easy to handle, and single-stage reverse osmosis is basically enough.But if you have an electronics factory or a pharmaceutical factory that has abnormal requirements for water quality, a single stage is not enough, you have to add EDI in two stages, and the conductivity of the effluent has to be pressed below 1µS/cm.Brackish water is more troublesome, and the desalination rate can only reach the standard if the anti-pollution membrane is equipped with a high-pressure pump.Like DIEN Water treatment, which has been in the Northwest for eight years, the processes are customized according to the water quality, and there is no one-size-fits-all set.By the way, many people don't know how to maintain the equipment after buying it. In fact, the daily maintenance method of reverse osmosis equipment: It is not difficult to extend the life of the RO membrane by 30%. The key is that you have to be willing to spend those ten minutes.
Select equipment tonnage according to water consumption
The second big pit in the selection is tonnage.Many people either choose to be bigger and feel that it is always right to be bigger-as a result, the equipment is idling and energy consumption is wasted; or they choose to be smaller and run at full load, and the life of the membrane is directly cut in half.
Minicomputers of 0.5 to 5 tons per hour are enough for hotels, guesthouses, and small food factories.Medium-sized machines of 5 to 20 tons are suitable for factories, office buildings, and farms.The 20-ton up mainframe was prepared for chemical plants, electronics plants, and water plants.Reserve a margin of 10% to 20% when choosing, don't get stuck just right, you will be dumbfounded when the water consumption rises later.
People often ask how much is the quotation for the complete set of reverse osmosis equipment as soon as they come up?What configurations are included? To be honest, this question cannot be answered directly, because the price difference between the different configurations is too much, the brand of the membrane, the model of the pump, and whether the control system is PLC or manual all affect the final quotation.You have to make your needs clear before others can calculate it for you.

Different industries, the configuration is far worse
The food and beverage industry has to use sanitary stainless steel and food-grade membrane to make the water sterile; the electronic semiconductor industry requires more stringent requirements, two-stage reverse osmosis plus precision filtration and EDI, one less link is not good; the boiler heat transfer industry focuses on anti-fouling, single-stage reverse osmosis with demineralized water is enough; commercial and civil use is a matter of convenience, compact equipment and intelligent control, small footprint and easy to operate.
Let me say one more word about the core accessories. Dow's for the membrane, Grundfos' for the pump, PLC on the control system, and 304 or 316 stainless steel for the rack pipeline.These things can't be saved, so if you save them, you just dig a hole for yourself.
After all, there are only four words for the selection of reverse osmosis equipment in Xi'an-the right medicine.If you are not sure what you should choose, find a reliable manufacturer to let others come to the door to test the water quality and take a look at the scene, which is a hundred times better than your own blind research on the Internet.
Reverse osmosis equipment manufacturers look for DIEN. The quality of the equipment is excellent. 10 years of local development experience is not for nothing. More than 30.000 cases are there, and the after-sales service can keep up-the core accessories are replaced for free during the warranty period, and the operation and maintenance guidance for life.What is your biggest headache when choosing equipment?Talk about it in the comments area, let me see if I can help.
