    The Ultimate FAQ Guide for Stainless Steel Filters

    At present, it is estimated that a little over 2 billion people across the globe reside in regions with a constrained supply of freshwater. This means that billions of people are forced to exploit water filtration technologies to convert polluted water into usable clean water. The global freshwater deficit is currently being met by filtering groundwater, seawater, stream water, and brackish water. This is made possible by first-rate water filtration systems manufactured using high-level materials like stainless steel to withstand aggressive contaminants. Our discussion today leans towards stainless steel filters, their distinct types, working principles, and roles.

    Figure 1 Stainless steel water filters.

    What is a Stainless Steel Filter?

    A stainless steel filter is an elaborate device that employs biological, physical, or chemical processes to extract undesirable constituents from water. The filtration barrier or medium is enclosed in a stainless steel housing, which is highly impervious to rust or corrosion. The housing or filtration vessel also protects the filtration media and other essential filter components.

    Other types of materials used to manufacture water filter housings include fiberglass, aluminum, and high-quality plastic. Presently, there are numerous types of media filtration systems, each specifically made for a distinct application. The most prominent water filter systems include membrane-based filters, mechanical filters, and ion exchange filters. In addition, they exploit different filtration processes i.e. chemical, physical or biological.

    NEWater has an outstanding history of manufacturing first-rate stainless steel water filters among other water treatment systems. We currently serve a global market comprised of commercial enterprises, industries, institutions, and even households. Our systems are fairly priced and we offer numerous pre-sale and after-sale services to optimize your purchasing and user experience.

    What Are the Different Types of Stainless Steel Filters?

    The number of applications and enterprises in need of water filtration continues to bulge as populations and industries grow. These enterprises rely on different types of feed water and most likely demand different grades of filtered water. Therein, manufacturers of water treatment systems have come up with different types of stainless steel filters to sufficiently satisfy the distinct demands of a heterogeneous market. Below, we take a brief look at the most renowned stainless steel water filters.

    ●       Stainless steel multimedia filters.

    Multimedia water filters are elaborate filters made up of three or more filtration media. They are chiefly deployed to minimize the presence of Total Suspended Solids (TSS) and turbidity in water. A typical multimedia filter consists of a layer of sand, anthracite, and garnet. This filtration media is arranged according to porosity (from the largest to the smallest). Owing to the presence of multiple filtration media, multimedia filters are comparatively more effective than traditional single-layer filters.

    ●       Stainless steel pressure sand filters.

    Stainless steel pressure sand filters simply consist of a single filtration media (Sand). The media is however arranged in multiple layers based on porosity and gravity. Pressure sand filters also eradicate turbidity and suspended matter but they are not as effective as multimedia filters.

    Figure 2 Stainless steel pressure sand filters.

    ●       Stainless steel carbon filters.

    Carbon water filters are also single media water filters. They rely on carbon granules of block carbon to expel unwanted contaminants. Stainless steel carbon filters essentially employ three processes to seize objectionable elements; mechanical filtration, electrokinetic adsorption, and physical adsorption. They eliminate varying chemicals including pesticides, chlorine, and chloramine as well as VOCs and pollutant gasses.

    ●       Stainless steel reverse osmosis filters.

    Reverse osmosis filters are membrane-based water filters that are primarily driven by pressure. They are one of the most popular water filters and can be used in numerous applications thanks to their diverse and extremely high impurity removal rate. Ordinarily, RO water filters eject minerals, dissolved solids (up to 99.7%), microbial pathogens, organics, and nutrients among others. Other types of stainless steel membrane filters are;

    How Do Stainless Steel Filters Function?

    Stainless steel filters generally employ varying water filtration mechanisms to expel distinct impurities from water. Currently, there are over 10 elaborate water filtration processes with some dating back to ancient times. Ancient technologies like distillation have been modernized while newer technologies have also been invented. Here is a summary of today’s most prominent water filtration processes.

    ●       Mechanical filtration.

    Mechanical filtration gets rid of impurities by passing polluted water through porous filtration media. This process is synonymous with sieving and it is employed in media filters such as multimedia filters and pressure sand filters. The following animation demonstrates how conventional media filters function,

    ●       Membrane filtration.

    Membrane filtration is one of the most effective and renowned water filtration technologies at present. This technology is essentially pressure-driven and it separates objectionable components from water using semipermeable membranes. Membrane filtration processes are mainly divided into;

    • Reverse osmosis.
    • Nanofiltration.
    • Ultrafiltration.
    • Microfiltration.

    These processes are primarily differentiated by the porosity size of their respective membrane perforations. For instance, reverse osmosis membrane filters have pores measuring approximately 0.0001 microns while ultrafiltration membrane pores measure roughly 0.005–0.1 μm.

    ●       Ion exchange filtration.

    Ion exchange is a distinct water filtration process that technically replaces undesirable ions with less-objectionable ions. This process is mainly used to extract dissolved ionic impurities from water. The eliminated impurities include hardness ions (Ca2+ & Mg2+), iron, nitrates, chlorides, and heavy metals.

    ●       Ultraviolet filtration.

    Ultraviolet (UV) sterilization or filtration is a water disinfection process used to eliminate or inactivate harmful microorganisms found in water. UV filtration is a chemical-free process that utilizes germicidal rays (at a wavelength of 253.7 nm) to destroy bacteria, fungi, viruses, and other pathogens.

    Figure 3 Stainless steel reverse osmosis filter system.

    What Are the Advantages of Using Stainless Steel Filters?

    Stainless steel is primarily used to manufacture stainless water filter vessels and housing due to its corrosion resistance. This in turn prolongs the lifespan of water filters by mitigating rusting and untimely fouling. Here are additional advantages of stainless steel filters.

    ●       Hygiene.

    Stainless steel keeps bacteria, molds, and other impurities away from your filter. In addition, they are easily cleaned unlike filters made from plastic or other material. Stainless steel filters can be thoroughly washed using clean water and soap.

    ●       Cost-efficient.

    Maintaining a stainless steel filter is pretty low given that the filters are not susceptible to premature fouling or corrosion. Their durability allows you to reap maximum rewards from your investment.

    ●       Resistance to rust.

    Raw water often consists of corrosive impurities such as dissolved salts. Stainless steel however consists of at least 10.5% chromium, which typically reacts with oxygen to a protective film that makes the stainless steel anti-corrosive.

    ●       Longevity.

    Compared to water filters made from other materials, stainless steel filters are relatively more durable. This is primarily because they are immune to corrosion and rust. Furthermore, they can withstand high pressure and extreme temperatures.

    Which is the Best Stainless Steel Filter for Drinking Water?

    Drinking water is a basic human need. Consumption of contaminated water can have devastating effects on the user hence public health institutions like the WHO have laid out stringent regulations to govern drinking water quality. Varying water purification systems can be employed to generate safe drinking water. The best filter however can only be determined by the composition and concentration of the raw water.

    In most drinking water purification applications, two or more water filters are often integrated. For instance, carbon filters and reverse osmosis membrane filters. If the raw water is mildly contaminated, for instance, tap water, a standalone drinking water filter can be sufficient. Stainless steel reverse osmosis membrane filters are quite popular drinking water filters thanks to their versatile impurity eradication.

    Additionally, drinking water filtration systems are frequently assimilated with polishing or post-treatment systems. For example, RO/UV water filtration systems effectively eradicated dissolved solids and microbial pollutants. To purchase the best drinking water filtration system, first, establish the composition and concentration of your feed water.

    Which Stainless Steel Filter is Ideal for Salty Water Desalination?

    Salty water is generally water with a Total Dissolved Solids (TDS) content of 1,001 ppm or higher. Thanks to advanced filtration technologies, it is now possible to desalinate or extract dissolved salts from saline water thereby generating fresh water. Saline water desalination is primarily accomplished using a number of elaborate water filters. The most effective desalination technology at present is reverse osmosis.

    Stainless steel reverse osmosis filters are inarguably the most effective saltwater desalination systems. They eliminate 95% to 99.7% of dissolved salts. In addition to this, they extract microbial pathogens, organic chemicals, metals, and minerals. To effectively desalinate seawater or brackish water, RO water filters are supplemented by elaborate pretreatment filters (sediment and carbon filters).

    Thanks to stainless steel, they are immune to corrosion, high temperatures, and pressure. Other filtration systems that are frequently exploited to desalinate salty water are thermal distillation systems and water deionizers.
