FG Water - Model iDesalt C Series -Seawater Reverse Osmosis System
The iDesalt C Series watermaker by FG Water Technologies is engineered to convert seawater or highly saline brackish water into potable water utilizing advanced reverse osmosis technology. This containerized desalination system integrates essential components such as pretreatment systems, RO systems, and chemical dosing mechanisms within a compact design, minimizing the need for extensive on-site installations. It is crafted to meet industry standards like ASME and ASTM, ensuring durability and performance. Featuring advanced technologies like a super duplex high-pressure pump and an isobaric pressure exchanger, it enhances energy efficiency and operational reliability. The system is capable of producing 50 to 2000 m³/day of pure water, making it suitable for varied industrial applications, including island residential, hotels, and construction sites. Its modular design allows for easy transport and installation, with options for additional components based on site requirements and system specifications.
Desalt C is available for both indoor and outdoor use. All the desalination components are pre-assembled in 1 to 2 containers, including the piping and control systems, which considerably reduces the on-site installation workload and time required for effective fresh water production. The design and manufacturing of the system comply with ASME, ASTM, IEC, and other internationally recognized industry standards. The fresh water capacity of fastROC is 50 to 2,000 m3/day (2,040-83,270 liters/hour.
Description
iDesalt C series watermaker is designed to produce high quality portable water from sea water or high salinity brackish water.
Together with our 2 pass RO or even EDI system, we could provide highly pure water for industrial or commercial usage.
C series watermaker produce pure potable water from 60 to 1000 ton (15 -260 thousand gallons) per day.
iDesalt C series watermaker is a containerized desalination system based on reverse osmosis principle which is the most popular water treatment technology in the world.
C series watermaker is designed to install the pretreatment system, RO system, chemical cleaning system and chemical dosing system all into the container. Containerized design minimize the site installation and erecting time of the desalination system. No need extra roof for the system.
Containerized system also make the transportation much easier.
To ensure the reliability of the watermaker, the core parts are from the well-known manufacturers in water treatment area, such as Danfoss, LG Nano, ROPV, Siemens, Schneider, ABB, etc.
iDesalt watermaker are designed and manufactured on the basis of the industrial standard: ASME, ASTM, IEC, etc.
The seawater is taken by an intake pump and sent to a feed tank (if seawater is taken from a very close place and the water turbidity is quite low, seawater could be sent directly to the Watermaker).
Seawater from feed tank is boosted by feed pump and is sent to media filter to remove particles. After too pass cartridge filter, seawater is pressurized by high pressure pump and sent to membrane. Thus we got fresh water, while the same time the concentrated water is discharged directly. Please refer the following process flow diagram for more details.
- Containerized design minimize the site installation and shorten the erecting time. Containerized system save cost from transportation and site civil works.
- Simple process, feed pump is used as backwash pump for media filter.
- Automatically backwash system for media filter.
- 3 step filtering ensure the safe operation of high pressure pump, energy recovery device and RO membrane.
- Super duplex high pressure pump using axial piston principle from Danfoss, higher efficient, lighter, more compact than common plunger pump, and only one service is needed for up to 3 year.
- Super duplex energy recovery device using isobaric pressure exchanger principle from Danfoss, much higher efficient than energy recovery turbine, and only one service is needed for up to 3 year.
- High pressure hose lower the vibration and noise level, simplify the pipe connection.
- Sch40 duplex high pressure pipe (EN1.4462/UNS S32205) and fittings, long life and highly corrosion resistant.
- Low fouling, high salt rejection, low pressure RO membrane from LG Nano.
- 5 layers of corrosion resistant paint protect carbon steel frame and container salt fog leaking water. A hardwearing plastic floor cover avoid the damage of the paint.
- Siemens, ABB or Schneider parts ensure the reliability of the control system.
- For C-E series watermaker, 10 inch touchscreen is integrated, ease the operation.
- Optional intake pump and feed pump.
- Optional insulation decoration kit for container
- Island residential
- Hotels, resorts
- Construction Site
- Emergent water supply, mobile water plant High salinity underground water

Note: if the feed water is not natural seawater or worse than above, please contact us.
5.2 Product water quality
- Standard 1) : acceptable drinking water quality for WHO (4 edition)
- Conductivity (online monitoring) 2) : < 1000 μS/cm
Note:
- If the source water is natural seawater (or salt water)
- If the water is for clean or irrigating, higher conductivity might be acceptable
