    The Ultimate FAQ Guide for Small Reverse Osmosis Systems.

    To reinforce the scanty supply of potable water from the diminishing freshwater reservoirs, the majority of households and commercial entities have turned to water treatment. In response, providers of water treatment solutions have devised numerous water treatment mechanisms and accompanying equipment.

    Reverse osmosis has particularly gained traction among households and commercial enterprises thanks to its high output and low operating costs. In an attempt to help you understand household water treatment, the following article elaborates on small RO systems.

    Small reverse osmosis system

    What is a Small Reverse Osmosis System?

    A small reverse osmosis system is essentially a low-volume water treatment unit that uses pressure to force the elimination of dissolved solids through semipermeable membranes. They are tailored for conventionally small portable water applications and are quite affordable. Despite being available in varied designs, small reverse osmosis systems guarantee smaller footprints, easy installation, and stress-free operation.

    Customarily, they come equipped with pre-filters, which proactively avert the probable blocking of the perforated RO membranes. Reverse osmosis systems are adaptable hence they are broadly utilized in seawater desalination, well water treatment, and brackish water desalination among other applications.

    What are the Main Features of Small Reverse Osmosis Systems?

    Small RO systems are chiefly characterized by their conventionally small capacities and compact designs. They are considerably light in weight, occupy smaller footprints, and have uncomplicated user controllers. Since they are chiefly customized to eradicate total dissolved solids, they have maximum TDS levels ranging from 1000ppm to 45,000ppm. The maximum TDS range accorded depends on the salinity of the imminent feed water.

    Despite being classified as small reverse osmosis systems; they support varied daily capacity ranges. Typically, the standard capacities of small RO systems range from 350 GPD to 15,000GPD. They rely on high rejection membranes, which eliminate between 95% to 99.7% of dissolved solids and have efficient recovery rates.

    Which Pretreatment Systems Are Used in Small Reverse Osmosis Equipments?

    Typical reverse osmosis systems comprise pretreatment systems whose constitution depends on the quality of the feed water. Prior to choosing an ideal pretreatment system for your small RO system, you must first establish your feed water’s composition and concentration. The following are pretreatment systems ideal for use in reverse osmosis systems.

    ● Media filtration systems.

    Conventional media filters such as pressure sand filters and contemporary media filters like multimedia filters are almost mandatory for all reverse osmosis systems. They eliminate the threat of membrane clogging by filtering out suspended solids, colloids, debris, dust, and undissolved solids. Pressure sand filters customarily shrink the TSS levels to 25-50 microns whereas multimedia filters bring down the TSS concentration to 10-25 microns.

    ● Ultrafiltration systems.

    Membrane filtration systems such as ultrafiltration and nanofiltration systems are considered to be the perfect pretreatment for reverse osmosis systems. UF filters in particular remove turbidity and high-molecular-weight elements from feed water thereby thwarting the risk of RO membrane fouling.

    ● Water softeners.

    Water softener systems are mainly a necessity in well water treatment due to the high concentration of hardness ions (Ca2+ and Mg2+). They utilize ion exchange resins charged with sodium ions (Na+) to eradicate the hardness minerals. The other RO pretreatment systems commonly exploited are:

    • Activated carbon filters.
    • Iron filters.
    • Chemical dosing systems.
    • Pre-UV sterilizers.

    What are the Main Applications of Small Reverse Osmosis Systems?

    Small industries, households and commercial entities in search of reliable portable water supplies are now more equipped to combat water scantiness thanks to small RO systems. Their suitability in treating varying sources of raw water including tap water, well water, rainwater, seawater, and brackish water further widens their application fields.

    Small reverse osmosis(RO) systems are utilized in households as RO watermakers. They generate high grades of product water, which are essentially used for drinking and other utility purposes. Additionally, they are used in seawater desalination for both onshore and offshore applications. In seawater desalination, they are mainly utilized in boats, coastal homes, beach resorts, and restaurants.

    Laboratories also utilize small reverse osmosis systems as part of their advanced laboratory water purification systems to generate laboratory-grade purified water. Moreover, they are deployed to treat well water for small business complexes, hospitals, and industries.

    How do Small Reverse Osmosis Machines Function?

    Irrespective of size and production capacity, all reverse osmosis systems employ similar working principles. They characteristically decontaminate feed water through size exclusion enabled by partially permeable membranes. High-pressure pumps are attached to RO systems to provide pressure higher than the natural osmotic pressure. Subsequently, the typical osmosis process is reversed resulting in an inversed water flow from higher concentrations to low concentrations.

    The first process in reverse osmosis water treatment entails preconditioning the feed water. A variety of pretreatment technologies are often employed depending on the concentration of the feed water. The preconditioned water is then pumped through the RO membrane element under pressure. The microscopic pores (measuring 0.0001 microns) on the membrane hold back constituents with a molecular weight of over 150-250 Daltons while permitting the pure solvent and low-molecular-weight substances passage.

    The blocked constituents are let out of the RO system as wastewater or brine. Before disposing of brine, you are advised to treat it to mitigate environmental pollution. The water on the permeate stream is harvested and can be instantaneously used or refined using an appropriate post-treatment mechanism. The entire RO water treatment process is well-described in this video.

    What is The Service Flow Rate of Small Reverse Osmosis Systems?

    Flow rate simply computes the quantity of water flowing through your reverse osmosis system per minute. Your system’s flow rate is ordinarily indicated in gallons per minute (GPM) or M3/day and in reverse osmosis systems, the flow rate is either feedwater flow rate, permeate flow rate or concentrate flow rate. It is an essential component that determines the number of product water gallons you derive from your reverse osmosis machine in an hour or day.

    For small RO systems, their service flow rates are not as high as those of large reverse osmosis systems. They are however endowed with distinct flow rates to adequately cater to the distinction in customer demands. NEWater’s small reverse osmosis systems have standard flow rates ranging from 2m3/day to 70 m3/day.

    Which Types of Small RO Systems Do You Provide?

    The primary parameter employed to classify small reverse osmosis systems is based on the type of feedwater treated. Therein, the main types of small reverse osmosis systems include seawater desalination systems, brackish water RO systems, and well water RO plants. Other classifications are based on areas of specialization e.g. laboratory RO water treatment systems and industrial RO systems.

    ● Well water RO units.

    Most regions deprived of fresh water and located miles off coastal waters primarily rely on well water. This water resides in underground reservoirs and is bound to pick up contaminants such as minerals, organic chemicals, and metals from the surrounding rocks and soil. We manufacture specialized RO systems for households, industries, and commercial enterprises that eliminate unwanted minerals, heavy metals, bacteria, viruses, and organic water from groundwater.

    ● Seawater desalination systems.

    Seawater is presently aiding millions of people across the globe to combat the devastating freshwater scarcity. To aid convert seawater into product water, NEWater manufactures seawater reverse osmosis with impeccable salt rejection rates (up to 99.7%). Their maximum TDS range ranges from 35,000 to 42,000ppm and is suitable for residential, commercial, and industrial applications.

Underneath, our expert discusses the crucial factors that will guide you into purchasing the ideal small reverse osmosis system.

    ● What is the composition of your feedwater?

    The common sources of feed water are seawater, groundwater, tap water, and brackish water. Each feedwater type will necessitate a customized reverse osmosis system hence you must first determine your source of feed water. Additionally, you need to establish the specific contaminants present in your feed water and their varied concentrations.

    ● What quality of water do you desire?

    Despite using similar technologies and equipment, the quality of RO permeates collected is likely to differ depending on the feed water composition. When you are fully aware of the product water grade you want, you can inform your manufacturer to make the necessary customizations to ensure your quality demands are met.

    ● How much product water do you want?

    The key variables to factor in when purchasing reverse osmosis systems based on production capacity are the daily capacity range and the flow rate. The gallons of potable water produced in a day should match the quantity demands of your project.

    Back to the guide ⇪

    What is the Energy Consumption Rate of Small Reverse Osmosis Equipments?

    Size and the production output are essential components that massively influence the amount of electricity bill you have to settle. Small reverse osmosis systems characteristically utilize low-power pressure pumps consequently resulting in considerably lower energy consumption.

    Energy consumption is additionally influenced by the concentration of the respective feed water. Typically, seawater desalination consumes the highest energy due to the high salinity levels. For instance, an RO seawater desalination system delivering 460 liters per hour of product water from seawater with a TDS level of 40,000ppm will consume approximately 3.5kWh/m3 or lower.

They are energy-efficient, have low maintenance demands, and are environmentally friendly.

    Back to the guide ⇪

    Do Small Reverse Osmosis Equipments Necessitate Post-Treatment?

    The employment of a post-treatment phase in reverse osmosis simply hinges on the quality of potable water desired. For instance, drinking water generated via reverse osmosis is likely to demand remineralization owing to the low mineral count in it. Calcium and magnesium are particularly added to the RO permeate in compliance with WHO standards which recommend amounts of 30 mg/l and 10 mg/l respectively.

    Furthermore, UV water disinfection may be required to completely inactivate all waterborne microorganisms. Purified water can also be generated from RO water by refining it using electrodeionization or conventional water deionization. To eliminate unpleasant odors and awful tastes from the water an activated carbon filter may be exploited to get rid of the organic chemicals, VOCs, and chlorine.
