    The Ultimate FAQ Guide for Whole House Nanofiltration Systems.

    Water hardness, microbial contamination, and saltiness are some of the most common water problems faced in households across the globe. The ongoing freshwater scarcity has forced households to explore alternative water sources and most of these water reservoirs are mildly or greatly polluted. Luckily, we live in a world endowed with immaculate technologies that facilitate the optimal removal of objectionable contaminants. These technologies include membrane filtration processes such as nanofiltration and reverse osmosis. In today’s article, we will be exclusively delving into nanofiltration water treatment, the respective equipment, and how homes can benefit from nanofiltration systems.

    Figure 1 Whole house nanofiltration system.

    What is a Whole House Nanofiltration System?

    A whole house nanofiltration system is a membrane filtration unit designed to remove hardness-causing ions among other objectionable pollutants from incoming household water. Ideally, whole house nanofiltration systems are also referred to as point-of-entry systems because they are installed where the water supply line enters your house. As such, they treat virtually all water entering your house before it is dispersed into the different outlets e.g. kitchen sink and bathroom.

    Nanofiltration (NF) filter systems essentially depend on pressure to force the alienation of undesirable pollutants like calcium and magnesium using semipermeable membranes. Their working principles are quite similar to those of ultrafiltration and reverse osmosis systems. The primary difference is the porosity size of the semi-porous membranes. Nanofiltration membranes have perforations whose size is bigger than RO membrane pores but smaller than ultrafiltration membrane pores.

    With an average porosity size of 0.001 microns, whole house NF systems can sufficiently filter out dissolved organics, multivalent ions, antibiotics, herbicides, and endotoxins. The NF membrane employs size and weight-based elimination to separate unwanted solutes from solvents. We manufacture first-rate whole house nanofiltration systems characterized by impeccable productivity, cost-efficiency, durability, and reliability.

    How Do Whole House Nanofiltration Systems Work?

    Whole house nanofiltration systems filter out impurities of a certain size and molecular weight range. They accomplish this by utilizing partially porous membranes with a porosity size of roughly 0.001 microns. However, for the semipermeable membranes to separate the solutes from the solvent, pressure is needed and typical nanofiltration operates at pressure levels ranging from 50 to 225 psi.

    Quite often, nanofiltration systems are preceded by elaborate pretreatment units. This eliminates aggressive impurities before they get the chance to clog or foul the NF membranes. Sediment filters, chemical dosing systems, and carbon filters are some of the most effective pretreatment systems used. After pretreatment, the raw water (feedwater) is then forced through the semipermeable NF membranes at a feed pressure of 50 to 225 psi.

    Multivalent ions and organics with molecular weights surpassing 200 to 400 are eliminated by the partially porous membranes while water molecules filter through the membranes. The filtered water accumulates on the membrane’s permeate side while the expelled impurities accumulate on the membrane’s retentate side. The NF permeate can be immediately used or further treated to elevate quality. Here is a comprehensive video illustration of the nanofiltration water filtration process.

    Figure 2 Nanofiltration process.

    What Are the Main Features of Whole House Nanofiltration Systems?

    Despite sharing a number of traits with other membrane filtration systems, nanofiltration filter systems are unique in their own distinct ways. They rely on semipermeable membranes and the average NF membrane has perforations with an average size of 0.001 microns. This allows them to filter out objectionable impurities with sizes and molecular weights greater than the average pore size. Underneath, we are going to look at some of the primary features that characterize whole house nanofiltration systems.

    • They are mainly pressure-driven and typically operate at a transmembrane pressure ranging from 50-225 psi.
    • They filter out impurities using partially permeable membranes with porosity measurements of approximately 0.001 microns.
    • They are ideal for extracting divalent and trivalent ions hence they are mainly used to soften hard water.
    • NF filters are also ideal for removing dissolved salts, especially those made up of divalent ions like magnesium sulfate (90-98%). Their removal rate for monovalent ion salts such as sodium chloride ranges from 20 to 98%.
    • They eject virtually all organics whose molecular weight falls within 200-400 Daltons.
    • They have a molecular weight cut-off (MWCO) of 0.2 to 10 kDa.
    • The nanofiltration membranes used can function optimally at pH levels ranging from 2 to 11.
    • They support temperatures as high as 45°C.

    Their water permeability is high and they are resistant to compaction.

     What Do Whole House Nanofiltration Systems Do?

    Nanofiltration water purification systems generally eliminate a wide array of objectionable constituents from water. Therein, they are often exploited distinctively by different households. Below, we will be walking through some of the primary functions, whole house nanofiltration systems fulfill.

    ●       Water softening.

    Water hardness is chiefly caused by calcium and magnesium. It is a common problem that most households have to deal with. However, with a whole house nanofiltration system, you can wave goodbye to all the devastating problems caused by water hardness. They include scaling, extravagant use of soap, skin and hair dryness among others. NF membranes filter out 90-98% of multivalent ions, which include Ca2+ and Mg2+. They are worthy alternatives to ion exchange water softeners.

    ●       Salt removal.

    Whole house NF systems have high salt rejection rates when it comes to divalent anion salts. These salts include magnesium sulfate and a typical NF membrane filter can remove 90-98% of these salts. The salt rejection rate of monovalent anion salts is relatively challenged and it ranges from 20 to 98%. The perfect membrane filtration system for dissolved salts removal is unequivocally the reverse osmosis system.

    ●       Organics removal.

    A nanofiltration water system will efficiently extract all organic molecules characterized by a molecular weight ranging from 200 to 400 Daltons. The range of organic molecules separated by whole house nanofiltration systems depends on the size of the membrane pores. Underneath, are additional impurities extracted by nanofiltration water filter systems.

    • Metal ions.
    • Antibiotics.
    • Dissolved inorganics.
    • Insecticides, herbicides, and pesticides.
    • Latex emulsions.
    • Nitrates and sugars.

    How Much Does a Whole House Nanofiltration System Cost?

    The cost of purchasing and installing water purification systems has generally shrunk over the years. This is mainly down to the development of efficient production technologies and healthy market competition. Accurate price estimation is however difficult given that different systems are manufactured using distinct materials and are equipped with dissimilar features. For instance, a 100 GPM NF system is likely to be more expensive than a 50 GPM whole house NF system.

    NEWater manufactures whole house NF systems customized according to the client’s requirements. Therein, we provide accurate price quotations upon inquiry. When assessing, projecting, or planning on the financial aspects of a water treatment system, it is equally imperative to factor in the expected operational costs. The operational costs of an average whole house NF system include pretreatment, energy consumption, manpower, and maintenance.

    The operational expenses incurred when operationalizing a nanofiltration system are comparatively low and quite affordable. The operating pressure is quite low compared to reverse osmosis and this results in lower power usage. Less manpower is necessitated since the scale of operation is smaller and the system hardly necessitates repairs and replacements. Treating surface water using a standard nanofiltration system typically costs €0.214 per m3.

    Differences in production costs are however normal and expected due to the dissimilarities in operational conditions. For example, the expenses incurred when filtering low-quality feed water e.g. seawater are expected to be higher compared to costs incurred when filtering brackish well water or tap water. For high-quality, economical, and reliable whole-house nanofiltration systems, place your order from NEWater.

    Which Pretreatment Systems Best Suit Whole House Nanofiltration Systems?

    Pretreatment systems are technically water treatment systems deployed to filter out aggressive constituents prior to the primary water treatment system. They are often deployed to protect the primary water filter system from premature damage and complications that may lower their performance. Below are some of the most revered pretreatment systems compatible with whole-house nanofiltration systems.

    ●       Sediment filters.

    Sediment filters are filtration units specifically designed to eradicate colloids, debris, and floating solids in general. By removing these suspended solids, they shrink turbidity and avert membrane clogging. The risk of premature malfunctioning is also mitigated thereby saving on unnecessary repairs and replacements.

    ●       Activated carbon filters.

    Activated carbon filters remove chlorine, Volatile Organic Compounds (VOCs), and pesticides using a mechanism referred to as adsorption. Higher concentrations of chlorine in water increase the fouling propensity of NF membranes while other organic chemicals cause corrosion. The deployment of AC filters also improves the taste and odor of water by extracting unpleasantly smelling and tasting organic chemicals.

    ●       Chemical dosing systems.

    Chemical dosing systems are treatment devices used to administer chemical regenerants like chlorine into the water. The chemical regenerants then eliminate or nullify specific impurities. For example, a chlorine dosing system injects chlorine into the feed water consequently killing viruses, bacteria, and other microbes.

    What Are the Differences Between Nanofiltration Systems and Other Membrane Filtration Systems?

    At present, membrane filtration systems are divided into four; reverse osmosis systems, nanofiltration systems, ultrafiltration systems, and microfiltration systems. Underneath, we will briefly look at the distinct types of membrane filtration systems and how they compare to nanofiltration filter systems.

    Figure 5 Whole house reverse osmosis system.

    ●       Reverse osmosis systems.

    Reverse osmosis systems are without a doubt the most prominent membrane filtration systems. They are pressure-driven and exploit partially permeable RO membranes to separate undesirable impurities from water. Nanofiltration systems are also pressure-driven and exploit semipermeable membranes.

    They are however differentiated by the membrane pore size. A typical RO membrane has perforations measuring roughly 0.0001 microns while an NF membrane has pore sizes measuring 0.001 microns. In addition, RO systems extract dissolved solids at a rate of 95-99.7% while NF systems only eliminate 20-98% of dissolved salts.

    ●       Ultrafiltration systems.

    Just like nanofiltration and reverse osmosis systems, ultrafiltration (UF) filter systems are pressure-driven. They also utilize partially porous membranes but the membrane pores are smaller compared to those of RO and NF membranes. The porosity size of UF membranes is estimated to be 0.01 microns while the average pore size of nanofiltration systems is 0.001 microns.

    In comparison, NF membrane perforations are smaller than UF membrane pores. They are however bigger when compared to RO membrane pores. Ultrafiltration systems are mainly deployed to lower turbidity and shrink Total Suspended Solids (TSS) levels.

    Can a Whole House Nanofiltration System Treat Drinking Water?

    Every household needs a reliable supply of safe drinking water. However, there are millions of people across the globe without access to fresh drinking water. In recent years, efforts to minimize the number of people lacking drinking water have been significantly boosted by the development of effective and economical water purification mechanisms. These mechanisms include nanofiltration, reverse osmosis, and distillation.

    Nanofiltration continues to be deployed in drinking water purification thanks to its high impurity removal rates, dependability, and cost-efficiency. A whole house nanofiltration system will extract organics, inorganics, heavy metals, multivalent ions, and traces of dissolved salts. However, the deployment of NF systems as drinking water systems often necessitates supplemental systems.

    For instance, a supplemental UV water sterilizer should be integrated to effectively inactivate harmful microbial pathogens. When selecting the ideal drinking water purification system for your home, it is imperative that you comprehensively assess the concentration and composition of your feed water. At NEWater, we will provide free technical advice to ensure you procure the best drinking water purifier.
