    The Ultimate FAQ Guide for Hard Water Filters for Car Washing.

    Using hard water in cleaning applications can be very uninspiring and a cause of headaches. The water is known for leaving limescale deposits on pipes and its negative reaction with cleaning detergents. When used to clean cars, motorbikes, or boats, hard water often leaves hideous stains and spots, which can be an eyesore.

    Since most of the water fetched from underground and surface water reservoirs contains varying levels of hardness, numerous technologies have been developed to extract the hardness-causing minerals. In today’s article, we extensively discuss hard water filters, their elaborate technologies, and their massive role in car washing.

    Figure 1 Hard water filter for car washing.

    What is a Hard Water Filter for Car Washing?

    A hard water filter for car washing is a car wash water filtration unit deployed to expel hardness minerals from hard water. Hard water is typically defined as water harboring high volumes of minerals such as calcium and magnesium. For car wash facilities, it is extremely important to use softened water rather than hard water since hard water leads to extravagant usage of detergents, hideous spots, and limescale accumulation.

    In the modern era, we are blessed with multiple hard water filtration systems and technologies. Production technologies have evolved significantly and consequently lowered the cost of hard water filters while elevating their efficiency and productivity. Some of the most popular hard water filters available in modern markets include ion exchange systems, nanofiltration filter systems, and reverse osmosis membrane filters.

    At NEWater, we have amassed extensive craftsmanship over the past 20 years in manufacturing soft water filters for car washing. Our outstanding systems are characterized by their high productivity, efficiency, longevity, and dependability. They are customized together with befitting pretreatment units to optimize compatibility with your specific application.

    How Do Hard Water Filters for Car Washing Function?

    The varying types of hard water filters for car washing provided across the world, employ distinct water softening processes to expel the hardness-causing minerals. The distinct processes attain varying results but are all quite effective. Let us look at the primary water softening technologies currently in use;

    ● Ion exchange filtration.

    Ion exchange filtration is the most utilized water softening technology. The hardness-causing ions, particularly magnesium (Mg2+) and calcium (Ca2+) are technically substituted by the less-objectionable potassium (K+) or sodium (Na+) ions. The hard water, which can be well water, or tap water is fed into a mineral tank made comprising a cation exchange resin. The active sites of the cation exchange resin are negatively charged or anionic.

    This means that they have a high affinity for the positively charged calcium and magnesium ions. The hardness ions are subsequently exchanged for Na+ or K+ ions resulting in softened water. After some time, the cation exchange filter is regenerated to expel the seized hardness ions and restore the optimum softening capacity. This video will help you gain an in-depth understanding of ion exchange water softening.

    ● Reverse osmosis.

    Reverse osmosis is an elaborate water purification process mainly used to extract total dissolved solids (TDS). It also eliminates nearly all minerals including magnesium and calcium, which are the genesis of water hardness. Reverse osmosis is a pressure-backed process that uses semipermeable membranes to alienate numerous impurities from water.

    It is therefore heavily utilized in car wash enterprises to treat varying forms of feed water. Its isolated use to soften hard water is however not very popular. This is because the hardness minerals are likely to degrade the membranes and leave limescale deposits on other components.

    Figure 2 Membrane water softening.

    ● Nanofiltration.

    Nanofiltration is another filtration process that utilizes semipermeable membranes and pressure to expel objectionable constituents. Nanofiltration is however suited to removing divalent and trivalent ions such as calcium and magnesium hence it is often exploited to soften water. The membrane porosity size of nanofiltration membranes (0.001 microns) is relatively larger than that of RO membrane filters (0.0001 microns). This means that lesser pressure is necessitated during nanofiltration (50-150 psi).

    Which Are the Best Hard Water Filters for Car Washing?

    Continuous innovations in recent years have granted us a wide pool of hard water filters for pressure washers. You can now choose your ideal hard water filter from a pool of vast, high-quality filter systems. Beneath, we discuss the world’s most effective soft water filters for car washing.

    ● Ion exchange filters (softeners).

    Ion exchange filters customized for water softening are only equipped with a cation exchange filter. The resin of ion exchange water softeners is primarily charged with sodium (Na+) ions but potassium (K+) ions are also worthy alternatives. As their name suggests, they exchange the hardness ions (Ca2+ and Mg2+) ions with Na+ or K+ ions. Ion exchanger filters demand frequent regeneration to dislodge the seized hardness ions and restore the optimal presence of non-objectionable ions.

    ● Membrane softeners.

    Membrane softeners are membrane-based filtration units such as nanofiltration and reverse osmosis systems used to eradicate calcium and magnesium. Nanofiltration filter systems are, however, more suited to water softening than reverse osmosis systems. This is mainly because reverse osmosis membranes are highly susceptible to fouling caused by the hardness of minerals. In addition to softening hard water, nanofiltration filters also expel small quantities of dissolved salts, organic compounds, and waterborne viruses.

    Why Do I Need a Hard Water Filter for Car Washing?

    Pressure washer hard water filters are mainly installed in car wash entities whose water supply suffers from water hardness. The water supply can be municipal tap water, river water, groundwater, or even lake water. These water softener systems extract the mineral compounds responsible for the extreme water hardness ultimately producing hard water. When washing your car or a client’s car, the end goal is to have a sparkling car with no hideous spots or marks.

    This is easily achieved when you use soft water or deionized water. A car washing water filter is also likely to elevate the effectiveness of washing detergents like soap thereby saving on production costs. The soft water generated tends to be more friendly to metallic surfaces, unlike hard water. This mitigates premature damages and extends the lifespan of valuable apparatuses. Underneath are some additional benefits of portable soft water car wash systems.

    • They lower the maintenance costs of the pressure washer and other essential equipment.
    • They facilitate spot-free cleaning thereby leading to happy clients.
    • They are durable and can operate optimally for approximately 10 years.
    • They also extract iron traces (up to 5 mg/L).

    How Do You Regenerate Ion Exchange Filters for Car Washing?

    For ion exchange water filters, regeneration is an essential process that must be undertaken periodically to boost the filter’s performance levels. Technically, regeneration is a recharge process that seeks to drive out trapped suspended solids and hardness ions from the resin and consequently restore sodium or potassium ions. Ordinarily, sodium chloride or potassium chloride is used to recharge the cation exchange filter. Beneath, we walk through the varying stages of cation exchange filter regeneration.

    ● Backwash.

    To begin with, water is driven across the resin from bottom to top so as to force out the imprisoned suspended solids. The backwash water inflates the resin consequently leaving the trapped solids afloat. The floating solids are ejected together with the backwash water. During this stage, the disarranged resin beads are also rearranged.

    ● Brine draw.

    A brine solution containing sodium chloride or potassium chloride is drawn from the brine tank and flushed across the cation exchange resin. This process drives out the hardness ions constrained in the resin beads, consequently substituting them with Na+ or K+ ions.

    ● Slow rinse.

    The slow rinse process ideally involves pumping clean water through the resins to expel surplus brine from the brine draw process. The clean water is injected at a relatively low flow rate to permit optimum rinsing.

    ● Fast rinse.

    To conclude the regeneration process, fresh water is flushed through the resins at a relatively high flow rate. Typically, the final rinse can take approximately 20-50 minutes. The quality of water exiting the water softener should signal when to conclude the fast rinse process.

    Figure 4 Portable hard water filter for car washing.

    ● What Volume of softened water do you need?

    Assessing the filter’s size and capacity is a priority. Ensure that your preferred hard water filter has a capacity that matches your quantity demands. For instance, if you need 500 liters of soft water per hour, the filter should have a production capacity of at least 500 LPH.

    ● What quality of water is generated?

    Ensure that the pressure washer hard water filter you opt for generates potable water that meets or surpasses your quality demands. This will also help determine if you need a post-treatment system.

    ● What are the investment and operating costs?

    Budgeting in advance is essential. You can avoid future financial setbacks by adequately assessing the possible investment and operational costs of your ideal hard water filter. We provide quotations for distinct water treatment systems upon inquiry and our technicians can help you project the expected operational and maintenance costs.

    Which Pollutants do Car Wash Hard Water Filters Expel from Water?

    Car wash hard water filters are chiefly designed to soften hard water to ultimately allow for spotless car washing. They accomplish this by flushing out minerals that cause water hardness i.e. calcium and magnesium. However, the range and magnitude of impurities extracted by the hard water filters for car washing depend on the softening process employed.

    For instance, ion exchange water filters ordinarily extract positively charged minerals like magnesium (Mg2+), iron (Fe2+), and calcium (Ca2+). Nanofiltration filter systems eliminate multivalent ions like iron, magnesium, and calcium as well as viruses and small traces of dissolved salts.

    Reverse osmosis filter systems are more diversified in terms of the impurities they flush out of water. They extract nearly all minerals, dissolved salts, metals, living microorganisms, and organic compounds. If you intend to remove more impurities, you can supplement your soft water filter for car washing with other water purification systems.

    Back to the guide ⇪

    Which Media Filters Can Be Used to Supplement Hard Water Filters for Car Washing?

    The range of contaminants filtered out by hard water filters for car washing is typically constrained. This necessitates the assimilation of pretreatment and/or post-treatment systems to supplement the hard water filters, especially if the feed water quality is poor. Underneath are examples of supplemental systems that can help you get the best out of your hard water filter for a pressure washer.

    Activated carbon filters.

    Activated carbon filters are chiefly specialized to extract organic chemicals, volatile organic compounds (VOCs), herbicides, and chlorine from water. Their working principle is centered on adsorption and they can be deployed as pre and post-filters.

    Multimedia filters.

    Multimedia filters are intelligently designed to expel dust particles, colloids, and suspended solids from feed water. Additionally, they lessen the turbidity levels and are quite effective compared to traditional single-media filters. Multimedia filters often comprise a sand layer, an anthracite layer, and a garnet layer laid out according to porosity size and specific gravity.

    Figure 5 Multimedia filter.

    ●      Membrane filters.

    Membrane filters are mainly pressure-backed filtration systems that filter out undesirable elements using partially permeable membranes. There are four primary membrane filter systems differentiated by membrane pore size and impurities extracted. They can be incorporated into car wash water treatment systems as preliminary treatment units, primary purifiers, or post-treatment units. They include;
