    The Ultimate FAQ Guide for 4040 RO Systems

    The availability and accessibility of freshwater have been a fundamental concern for ancient and modern civilizations. The persistent rise in population has imposed further pressure on the already strained freshwater reservoirs, resulting in an unfavorable shortage of freshwater. To meet the worldwide need for drinkable water, industries, homes, and enterprises have been compelled to use alternate reservoirs such as the oceans, which contain 97 percent of the world’s water. This has been made possible by the development of inexpensive and extremely efficient water purification equipment. Today’s presentation will center on 4040 reverse osmosis systems and their application in various water purification settings.


    Figure 1 4040 reverse osmosis (R0) system.

    What is a 4040 Reverse Osmosis System?

    A 4040-reverse osmosis (RO) system is a membrane filtration system that uses 4040 RO membranes to remove unwanted impurities from dirty water. However, 4040 RO systems can also be employed in light industrial applications such as aquatics and window cleaning. They can be deployed to treat feed water drawn from various reservoirs, such as oceans, underground wells, faucets, and rivers, with the proper customization.

    The employed 4040 RO membranes have an exceptional removal rate of between 95 and 99.7 %. 4040 RO systems are highly effective at removing bacteria, viruses, minerals, organic compounds, and nitrates, despite their primary usage being the removal of Total Dissolved Solids (TDS). Their maximum TDS levels are frequently adjusted to correspond with the TDS values of the incoming feedwater, i.e. (1,000-45,000ppm).

    In the same manner, as conventional reverse osmosis systems, these systems are pressure-driven and are equipped with pressure booster pumps. In addition, 4040 RO units are equipped with elaborate pre-filters whose primary function is to remove damaging contaminants, hence preventing membrane fouling. NEWater is one of the leading manufacturers of reverse osmosis systems and other water treatment equipment. Our systems are specially developed and modified to provide optimal application compatibility.

    How Do 4040 RO Systems Function?

    Reverse osmosis is the method by which all reverse osmosis systems eliminate unwanted contaminants from water. Technically, reverse osmosis is the opposite of normal osmosis. By applying pressure to the feed water to overcome the osmotic pressure, the usual osmosis process is reversed. This causes water to travel from the stream with a high concentration to the stream with a lower concentration.

    Before forcing the feed water through the RO membrane filters, pre-filters are first deployed to filter out destructive contaminants. Sediment filters capture dust particles and suspended solids, whereas carbon filters eliminate organic chemicals, chlorine, and chloramines. The adequately pretreated water is then run through the high-rejection RO membranes at high pressure.

    The ultrathin membrane perforations block the passage of constituents with high molecular weights including dissolved salts, microbes, minerals, and organic compounds. These constituents are left on the retentate side while water molecules that pass through the semipermeable membranes move to the permeate side.

    In the end, you are left with the permeate stream, which contains the filtered water, and the concentrate stream, which contains the eliminated pollutants. If your application demands higher purity levels, you can polish the RO permeate using a post-treatment system such as a UV water sterilizer. The process of reverse osmosis water purification is well illustrated in the underlying video.



    What Are the Chief Benefits of 4040 Reverse Osmosis Systems?

    Quality, affordability, durability, and dependability are just a few of the benefits that 4040 RO system consumers enjoy. These water purification systems are equipped with PLC controllers that enable automatic control and operation. The machine is reasonably priced and does not require significant maintenance or operating costs. Additional advantages that have contributed to the widespread adoption of 4040 reverse osmosis systems are highlighted below.

    • They extract 95-99% of objectionable contaminants found in raw water, consequently producing high-quality product water.
    • They eradicate constituents known for causing unpleasant tastes and odors.
    • They have a high recovery rate. Their product-to-waste ratio is approximately 1:4.
    • The system is compact, easy to use, and portable.
    • Reverse osmosis also extracts bacteria and viruses thereby eliminating the need for post-treatment.
    • The RO membrane filters used are top-notch and can last up to 3 years.
    • They are energy-efficient.
    • They have pressure gauges, which help regulate the operating pressure.

    Figure 2 Reverse osmosis system.

    Which Pretreatment Equipment is Ideal for 4040 RO Systems?

    The ideal requirement for pretreatment equipment and the type of pretreatment equipment required is dictated by the characteristics of the feed water. For example, tap water is less likely to contain contaminants than seawater. If your supply water is significantly polluted, you will likely require a pretreatment system to reduce TSS levels, reduce water hardness, and eliminate chlorine. The systems listed below are among the most successful and efficient pretreatment systems used to complement 4040 RO systems.

    ● Sediment filters.

    Sediment filters are special filters specialized to alienate suspended matter, debris, and sediments from the feed water. Failure to remove these solids may result in membrane clogging and irreversible fouling over time. Typically, the sediment filters deployed in pretreating feed water for 4040 reverse osmosis units are 5-micron filters.

    ● Carbon filters.

    Carbon filters are ordinarily used together with sediment filters. However, they employ a different working principle and extract different impurities. They eliminate free chlorine, herbicides, Volatile Organic Compounds (VOCs), and a range of organic chemicals. Some of the organic chemicals removed are known for causing awful smells and tastes in water.

    Figure 3 Activated carbon pre-filter.

    ● Water softeners.

    Calcium and magnesium-rich feedwater deposits limescale on metallic surfaces and within pipes. Using a water softener system, it is possible to remove hardness minerals and so perhaps avoid scaling. Water softening systems that can be used to pre-treat feed water include ion exchange water softeners, nanofiltration systems, and antiscalant dosing systems.

    ● Pretreatment filters.

    Typical 4040 RO systems comprise a set of elaborate pre-filters. To safeguard RO membranes, 5-micron filters are generally utilized to remove suspended particles and debris. Carbon filters, water softeners, chemical dosing systems, and ultrafiltration filters are further pre-filtration technologies that can be installed.

    ● Membranes.

    The RO membrane is the primary component of a reverse osmosis machine. This membrane is a thin-film, partially permeable membrane that separates dissolved particles from water. Commercial 4040 RO membranes with an impurity removal score between 95 and 99.7 percent are typically utilized in 4040 RO systems.

    Figure 4 4040 reverse osmosis membrane.

    ● Feedwater valve.

    The feed water valve is a conduit that allows feed water to enter the RO system from its source. In 4040 reverse osmosis systems, the self-piercing valve, the angle stop valve, and the faucet adapter are utilized as feedwater valves.

    ● Automatic shut-off valve.

    The automatic shut-off valve is a self-operating valve that shuts off the water flow when it detects that the storage tank is full. Typically, the shut-off valve is engaged when the tank pressure reaches two-thirds of the supply pressure. The membrane cleaning skid, the post-treatment unit, and the storage tank are optional components.
