    Salt Water Filter System from NEWater

    NEWater uses an innovative design of saltwater filtration systems that can generate high-quality water alternative sources by favoring brackish and saline water over increasingly strained natural water resources. This helps us further our goal of protecting natural water sources around the world.

    With our saltwater filtration systems, we use reverse osmosis and deionization technologies to treat and purify water. In reverse osmosis, a pump is used to pressurize the water so that it can overcome the osmotic pressure and pass through membranes of different pore sizes, which are able to retain contaminants that may later be discarded through a separate stream. The water can then also be deionized with resins to remove salt and other mineral ions, reduce the hardness of the water and prevent scale buildup. Post-treatment methods are also available, such as carbon filters, which remove unwanted tastes, odors, and smells from the water, and UV filtration systems, which help remove microorganisms and viral pathogens.

    If you have any questions about our brine filtration systems, please send your questions to your team of customer service representatives.

    The Ultimate FAQ Guide for Salt Water Filter Systems?

    The utilization of saltwater in most applications is likely to have devastating repercussions hence there are constrained applications of saltwater. Consuming saltwater will bring you distressing health issues such as cramping and dehydration. Saltwater, which is available in plenty in seas, oceans, lakes, and underground aquifers has emerged as an alternative to the drying-up freshwater sources. Sophisticated and highly resourceful technologies in saltwater filtration emerged in the past decades and their adoption proliferates annually. Our discussion today is focused mainly on saltwater filter systems.

    Figure 1 Saltwater filter system.

    What is a Salt Water Filter System?

    A saltwater filter system is a water filtration system specialized to desalinate saline water and ultimately generate freshwater. Saltwater filter systems utilize distinct technologies to filter out dissolved salts from saline water. They are essentially deployed to desalinate brackish water, which is characteristically slightly saline, and seawater, which is naturally highly saline. Primarily, saltwater filters utilize ion exchange (IX) filters, RO membrane filters, or media filters such as sand filters for saltwater.

    Saltwater filter systems are eligible to treat any kind of salty water starting with slightly salty water at 1000-3000ppm and ending with highly saline water at >35,000ppm. Typically, they generate high-grade freshwater suitable for multiple applications including human consumption.

    How do Salt Water Filter Systems Work?

    Saltwater filter systems are customarily endowed with distinct filtration technologies. Primarily, reverse osmosis, deionization, and media filtration are exploited in most saltwater filter systems. However, reverse osmosis is more predominantly utilized. Beneath, we briefly look at these renowned processes that facilitate saltwater filtration.

    ●      Reverse osmosis filtration.

    Reverse osmosis is simply regarded as the best saltwater desalination technology courtesy of its high salt rejection rate. This is a pressure-driven process that alienates the dissolved salts using partially-permeable membranes. The saltwater is essentially pressurized using pressure from booster pumps thereby overpowering the natural osmotic pressure.

    Consequently, the saltwater is passed through the semipermeable membranes, whose microscopic perforations seize the dissolved salts. Reverse osmosis membranes also capture bacteria, viruses, minerals, and proteins among other objectionable pollutants. The water that penetrates through the membranes is collected from the permeate stream while the captured contaminants are ejected from the brine stream. Reverse osmosis saltwater filtration is best illustrated in the video below.

    ● Capacitive Deionization.

    Capacitive deionization is a saltwater filtration technology more suited to desalinating moderately or slightly saline water. CDI typically applies electrical potential difference by utilizing two electrodes, which are characteristically made of porous carbon to deionize saltwater.

    A typical CDI filtration cycle is accomplished in two steps. In the first step, which is typically referred to as ion electro-sorption, ions are inactivated in the electrode pairs. In the second step, the porous carbon electrodes discharge the ions ultimately regenerating the electrodes. This illustration explains in detail the CDI saltwater filtration process.

    ● Sand filtration.

    Conventionally, sand filtration is utilized to pretreat saltwater. This process alienates unwanted pollutants using a media layer made of sand with distinct sizes and gravity. The saltwater is evenly distributed atop the sand filter layer and thanks to gravity, it penetrates the filter layer. In the process, suspended solids, microplastics, benthic organisms, debris, and algae are seized and filtered water is collected at the bottom of the vessel.

    Figure 2 EDI reverse osmosis saltwater filter system.

    Which Salt Water Filter Systems Do You Manufacture?

    The reliance on saltwater filtration has grown exponentially in recent years and this has prompted the development of numerous saltwater filtration systems. NEWater has actively contributed to the resolution of freshwater scarcity by manufacturing highly dependable water treatment systems. Beneath, we expound further on our elaborate saltwater filter systems.

    ● Reverse osmosis saltwater filters.

    Reverse osmosis systems are heavily and widely used as saltwater filter systems for brackish and seawater desalination. They are suitable filtration solutions for saltwater with a TDS score ranging from >1000ppm to 35,000ppm. For extremely salty water, RO filter systems with upgraded TDS ranges (Up to 45,000ppm) can be utilized. Subcategories of our reverse osmosis saltwater filter systems include:

    Figure 3 Brackish water RO filter system.

    ● Sand filters for saltwater.

    Sand filter systems are essentially single-media filtration systems characterized by different layers of sand configured according to size and gravity. Typically, these filter systems decrease or fully eradicate the concentration of debris, turbidity, microplastics, and suspended solids. Alternatively, multimedia filters can be employed to eliminate the aforementioned pollutants.

    ● Saltwater distillers.

    Saltwater distillation systems essentially eliminate the dissolved salts through the processes of evaporation and condensation. Using a heating source, the saltwater held in the boiling chamber is heated until it vaporizes. The dissolved salts remain in the boiling chamber thanks to their high boiling points while the vaporized water is condensed to generate distilled water.

    What are The Primary Uses of Salt Water Filter Systems?

    Saltwater filter systems are primarily used to reinforce the product water sources accessible to mankind. They provide a dependable alternative to natural freshwater reservoirs, which are deteriorating rapidly. They turn saltwater into potable water, which can be consistently utilized in diverse application fields. In addition, they provide fresh drinking water to millions of thirsty people in water-deprived countries.

    Saltwater filtration systems help protect individuals from illnesses and health problems caused by waterborne impurities or excess salts. They also complement environmental conservation efforts by minimizing contamination and preserving natural freshwater reserves. When deployed to treat brine, they proactively mitigate the contamination of water bodies.

    Can Salt Water Filter Systems Produce Drinking Water?

    Yes. The appropriate utilization of a saltwater filter system results in the generation of high-grade water, which meets the threshold for safe drinking water. Current projections indicate that up to 40% of the global population experiences drinking water scarcity or lacks a safe drinking water source. Saltwater filter systems get rid of the dissolved salts, which primarily impede the consumption of salt water. Additionally, they eliminate other pollutants harbored by saltwater e.g. viruses and bacteria.

    Evidently, saltwater filter systems are being utilized to convert seawater and brackish water into healthy drinking water. Saltwater makers such as boat water makers are widely exploited in water vessels to provide drinking water to travelers and crew members. Home water makers are deployed in households, office buildings, beach resorts, and restaurants to supply fresh drinking water.

    Moreover, the quality of filtered water they generate can be refined using advanced technologies like UV sterilization and activated carbon filtration. These post-treatment methods polish the water by eradicating other contaminants and making it more palatable.

    How is Reverse Osmosis Tech. Used in Salt Water Filter Systems?

    In the modern water treatment world, reverse osmosis is unquestionably one of the widely utilized technologies. It is a high rejection mechanism capable of eliminating 95-99.7% of dissolved salts and other solids from saltwater. Reverse osmosis systems saltwater filter systems typically operate in the steps illustrated underneath.

    ● Pretreatment.

    The RO membranes in RO saltwater filter systems are protected from premature fouling by pretreatment. The saltwater is initially filtered using sediment filters, chemical dosing systems, or any appropriate pretreatment technology. With suspended solids eliminated from the feed water, the RO membrane can’t clog. Similarly, the threat of corrosion or scaling is nullified by pretreating the saltwater with carbon filters or ion exchange filters, or a chemical dosing system.

    ● RO membrane filtration.

    The primary filtration of the saltwater is undertaken in the reverse osmosis membranes. With pressure applied to the saline water, the conventional osmosis process is inverted to facilitate reverse osmosis. Two streams of water are essentially alienated by reverse osmosis membrane filters. Since the osmotic pressure has been overwhelmed, pure water is drawn to the side of the lowly concentrated side while the dissolved salts are seized by the membrane pores. The filtered water, which is referred to as RO permeate, is collected and can be polished or readily utilized.

    ● Post-treatment.

    If the RO permeate leaves a lot to be desired, it can be subjected to further treatment using distinct post-treatment processes. Utilized mechanisms include activated carbon filtration and UV disinfection.

    What are The Primary Features of Salt Water Filter Systems?

    Saltwater is characteristically very eruptive and can easily corrode metallic surfaces or pipes. Therein, saltwater filter systems are typically manufactured using non-corrosive materials like stainless steel or FRP material. In addition, they are equipped with pretreatment equipment that eradicates eruptive pollutants such as calcium and magnesium, which can cause scaling.

    Reverse osmosis saltwater filter systems meant for brackish water desalination have TDS levels of 1000ppm to 12,000ppm. Reverse osmosis seawater filtration systems have a maximum TDS level of 35,000ppm and support upgrades of up to 45,000ppm. A typical RO membrane filter has an estimated pore size of 0.0001 microns, which facilitates salt rejection scores of up to 99.7%.
