    Maintain your desalinator's performance

    Maintenance helps preserve system performance and reduce fouling of the reverse osmosis membrane.

    Pay particular attention to feed water quality, pre-filtration and membrane performance monitoring.

    Pre-filtration

    Regularly check the condition of your pre-filtration components to protect the membrane.

    Performance

    Monitor changes in the flow rate and quality of the water produced.

    Membrane

    Replacement depends on water quality and operating conditions.

    Seawater reverse osmosis membrane

    The seawater reverse osmosis membrane used is type 4021. According to the supplier documentation we have for this consumable, the recommended replacement interval is approximately 1 to 2 years.

    This interval is a guideline and may vary depending on salinity, raw water quality, pre-filtration, frequency of use and operating conditions.

    FAQ

    Frequently asked questions about the desalinator

    Flow rate, seawater, membrane and use

    How much water can the desalinator produce?

    The SW4021 has a nominal capacity of 50 L/h, equivalent to 300 GPD or approximately 1,200 liters per day under nominal operating conditions.

    Is the desalinator designed for seawater?

    Yes. It uses a reverse osmosis membrane designed for desalination. The supplier's specifications indicate a maximum feedwater TDS of 36,000 ppm and an SDI ≤ 5.

    What is the desalination rate?

    WTEYA states a desalination rate between 99.4 and 99.7 %. Actual performance varies depending on factors such as salinity, temperature and operating conditions.

    What membrane does the desalinator use?

    The SW4021 uses a type 4021 seawater reverse osmosis membrane.

    When should you replace the 4021 membrane?

    The supplier documentation we have for this consumable recommends replacement approximately every 1 to 2 years. This interval may vary depending on water quality and operating conditions.

    Is the desalinator truly portable?

    This is a compact, transportable desalinator measuring 610 × 320 × 497 mm and weighing approximately 40 kg. It is therefore much more compact than a fixed industrial unit, while still requiring suitable conditions for transport and use.

    Can you drink the water produced directly?

    The SW4021 is designed to produce desalinated water from seawater. For human consumption, the resulting water quality must be tested and meet applicable requirements. Additional treatment may be necessary depending on the source water and intended use.

    How does it differ from an industrial desalinator?

    The SW4021 prioritizes compact size with a nominal output of 50 L/h. For greater water needs, a professional or industrial unit can deliver higher production flow rates.
