Seawater desalination equipment is a device that obtains qualified water quality through reverse osmosis. The seawater is pressurized by a high-pressure pump and passed through the reverse osmosis membrane. Due to the high salt content of seawater, the reverse osmosis membrane must have the characteristics of high desalination rate, corrosion resistance, high pressure resistance, and pollution resistance. After treatment, the salt content of seawater is greatly reduced, and the TDS content is reduced from 36,000 mg/L to about 200 mg/L. The water quality is even better than tap water, suitable for industrial, commercial, residential and ship and warship use.
Reverse osmosis membrane method: high desalination rate, corrosion resistance, high pressure resistance, and pollution resistance.
Pretreatment system: includes multi-media filtration, activated carbon filtration, water quality reduction, PH adjustment and other steps to ensure long-term stable operation of the system. It is widely used in various scenarios and is efficient and convenient.
| Capacity | 3-320ton/day | dimension | Depends on the model |
| System recycling rate | 33% | Electricity | Customized according to your local site data |
| Output water quality | Complying with GB5749-22 drinking water quality standard | Electrical control protection level | IP56 |
| Color | customized | materials | Stainless steel 316 |
| Main parts | SPECK brand imported from Germany, and the reverse osmosis membrane uses the Dow brand from the United States | ||
| System function | 1. Overpressure protection for high-pressure pump outlet water. When the outlet pressure of the high-pressure pump exceeds 3.0MPa, the equipment will automatically shut down and sound and light alarm will be issued.
2. Underpressure protection for insufficient inlet pressure of the high-pressure pump. When the inlet pressure of the high-pressure pump is lower than 0.05MPa due to insufficient pretreatment water supply, it will automatically shut down and sound and light alarm will be issued. 3. Equipped with a manual multi-way valve, the sand filter can be filtered, backwashed and forward washed conveniently and quickly as needed. 4. The alarm system has manual confirmation and silencing functions. 5. Equipped with a reverse osmosis membrane cleaning system, the reverse osmosis membrane assembly can be physically cleaned, concentrated water replaced, chemically cleaned and filled with protective fluid. |

Q: Which machine should I choose?
A: It depends on your raw water quality and your requirements for permeate water.
Usually there are three parts: pretreatment, RO machine, and post treatment. Pretreatment could be UF(ultra filtration)
system,anti-scale dosing system, flocculant dosing system, disinfectant dosing system, water softener, sand filter, carbon
filter,security filter etc. Post treatment could be UV sterilizer, Ozonizer, ClO2 sterilizer, etc. And maybe you need an EDI system. We will choose proper process according to your raw water quality and permeate water purpose.
Q: What’s your machine material?
A: For pretreatment tanks, we usually use FRP or S.S. The RO frame could be S.S, carbon steel.For pipes, it is usually S.S and UPVC. We can choose material according to your special requirements.
Q: What’s the control method?
A: For pretreatment, you can choose manual or automatic; for the whole system, we use relay, PLC or man-machine interface remote controld.
Q: Which spare parts need to change regularly?
A: Filter cartridge in the security filter and RO membranes. For filter cartridge, it needs to change each 3-6 months, and for RO
membrane, you need to change each 1-3 years. It depends on your water quality and how you maintain the machine.
Q: What’s your warranty?
A: Our warranty is 1 year. But to our experience, our machine can work 5 years before repair.
