NEWater Anion Exchange Water Filters
NEWater anion exchange removes dissolved ions from a solution by attracting cations or anions using synthetic resins, then releasing (exchanging) counter-ions until the resin is exhausted. Ion exchange happens as the solution passes over a resin bed. Regenerating or replacing ions on the resin continues the process.
When compared to comparable systems, on-site resin regeneration uses a packed bed, and counter-current technology, which reduces chemical use and waste volume. We provide counter-current regeneration, which uses half as many chemicals and half as much water as traditional deionization systems.
NEWater Anion Exchange Water Filter Principles
With NEWater anion exchange resins, cation exchange resins, and amphoteric ion exchange resins are the three types of ion exchange resins. Water and other common solvents are insoluble in ion exchange resins. The majority of them are granular, but there are a few that are fibrous or powdery.
Resin particles range in size from 0.3 to 1.2 mm, with the majority falling between 0.4 and 0.6 mm. Under typical conditions, they have strong mechanical strength (robustness), chemical stability, and long service life.

Anion Exchange Water Filter from NEWater
NEWater has over 20 years of manufacturing experience in designing and producing high-quality anion exchange water filters. They allow you to safeguard your property, either as a homeowner or a business owner. They remove unwanted mineral and metallic ions to reduce the hardness of the water, preventing scale buildup and damage to appliances and equipment such as cleaners and heaters that are related to water.
Our anion exchange water filters replace unwanted minerals in water being treated with others. The ion exchange occurs in tanks that are composed of beds of resins, that may either be arranged according to their charge specificity or maybe in mixed beds. The anions in this case are attracted to the negatively charged resins and are replaced with other positively charged ions. These ions are usually chloride. A number of contaminants such as fluoride, sulfate, arsenic, and nitrates are removed in the anionic filtration process. The resins used have a finite replacement capacity, and can easily be recharged or regenerated to allow our anion exchange water filter to return to its initial condition. Post-treatment methods such as UV radiation treatment may also be used to remove microbial pathogens.

➣What is an Anion Exchange Water Filter?
An anion exchange water filter is a type of filtration medium made of ion exchange resins with positively charged sites that capture negatively charged ions from the feed water. Typically, anion exchange water filters are light in weight, porous, and available as beads, granules, or sheets. They are primarily charged with hydroxide (OH-) or chloride (Cl-) ions, which essentially displace the unwanted anions from water.
They are primarily used together with cation exchange water filters but they can be solely deployed to eradicate nitrates and in organic scavenging. Different resins can be installed in anion exchange water filters thereby diversifying their application fields. They are often accommodated in pressure vessels made of fiberglass or stainless steel.
➣What are the Main Uses of Anion Exchange Water Filters?
Ion exchange water treatment systems are generally utilized to eliminate unwanted ionic components from water. The ionic constituents are either positively charged or negatively charged hence the use of both anion and cation exchange water filters. Anion exchange water filters are specifically employed to eradicate anionic (negatively charged impurities). Here are the primary uses of anion exchange water filters.
● Nitrate removal.
Consuming water with a high nitrate content can cause the human body serious harm such as extreme heart rate and dizziness. It can also affect your skin negatively by giving it a gray or bluish color. Anion exchange water filters exploiting strong base anion resins are specifically designed to eliminate nitrates from water. Chloride ions held by the SBA resin beads are discharged to replace the nitrate and other negatively charged ions from the water.
● Organics removal.
The concentration of organics in water is measured as the total organic compound (TOC) level. It indicates the concentration of carbon in organic compounds found in water. Organics can be eliminated using both strong base anions and weak base anions.
Desilication refers to the effective eradication of silica (SiO2) from water. Silica removal using ion exchange is accomplished using strong base anions with hydroxide (OH-) ions. Anion exchange filters eliminate reactive silica thereby averting the accumulation of silica deposits on high-pressure boilers.
➣How do Anion Exchange Water Filters Function?
Anion exchange water filters can be employed in conjunction with cation exchange filters or as singular filters. Irrespective of their configuration they typically deploy similar working principles. At first, the feed water is sufficiently preconditioned using sediment filters to remove suspended solids.
Consequently, it is injected into the pressure tank holding the anion exchange resin. The anion exchange resin is primarily charged with hydroxide (OH-) or chloride (Cl-) ions. As the feed water permeates through the anion exchange resin beads, the unwanted anionic impurities in the water are attracted to the high-affinity active sites.
The resin beads then discharge the chloride or hydroxide ions, which are considerably non-objectionable to substitute the released pollutant ions. The repeated use of the anion exchange water filters results in exhausted resins thereby necessitating regeneration. The following visual illustration will help you understand the anion exchange water filtration process.
➣What are Anion Exchange Water Filters Made of?
Anion exchange water filters are cohesive water filtration units made of interlinked components with varied roles to play. Underneath, we unravel the primary components that make up a functional anion exchange water filter to help you understand your equipment better.
● The pressure vessel.
The pressure vessel is the tank manufactured from fiberglass (FRP) or steel that houses the other primary components. The anion exchange resin is held inside the pressure vessel and the entire filtration process takes place there.
● The anion exchange resin.
The anion exchange resin is primarily made up of a polymeric matrix attached to distinct functional groups. The anion resin beads are essentially charged with chloride or hydroxide ions, which are ultimately exchanged for the objectionable anionic pollutants. The resins must be regenerated periodically once the pollutant minerals overwhelm the functional groups.
● The control valve.
The control valve is tasked with monitoring and regulating the quantity of feed water injected into the pressure vessel for filtration and the amount of filtered water you collect. It consists of a meter or clock, which can be preprogrammed to automatically instigate the regeneration process.
➣How are Anion Exchange Water Filters Regenerated?
The regeneration process basically extricates the pollutant ions attached to the resin beads in the course of the in-service cycle thereby restoring the optimal functional capabilities of the anion exchange filter. The process is mainly enforced using two approaches; counter-current regeneration and co-current regeneration. Underneath, we expound on the primary steps adhered to during regeneration.
Backwashing is undertaken to force out the insoluble constituents like debris and colloids seized in the resin bed. Water is flushed into the pressure vessel from the bottom through the resin bed. This reclassifies the resin by eliminating air pockets. Backwashing must be regularly undertaken in co-flow anion exchange systems whereas, in counter-flow anion exchangers, it is enforced when the conditions demand so.
● Chemical injection.
Anion exchange resins are essentially regenerated using bases. Strong base anions are specifically regenerated using strong bases such as caustic soda (NaOH) or caustic potash. Weak base anion resins on the other hand are typically regenerated using weak alkaline solutions of sodium carbonate (Na2CO3), ammonia (NH3), or lime. The regeneration solution is flushed through the resins at a comparatively low flow rate.
● Regenerate displacement.
This process can also be referred to as the slow rinse. Essentially, water is slowly pumped through to flush out the regeneration chemicals. To mitigate damaging the resin beads, you must regulate the flow rate.
● Fast rinse.
To conclude the regeneration process, clean water is flushed through the anion exchange column at a normal service flow rate in the final rinse. The fast rinse is concluded once the water depicts a specific quality.
➣What are the Main Advantages of Using Anion Exchange Water Filters?
In essence, anion exchange water filters are highly-advantageous water treatment systems that can be utilized differently for different gains. They are often employed with cation exchange water filters to deionize water for varied applications such as laboratory water purification. They are also utilized individually to eliminate nitrates, silica, and harmful organic compounds from water.
Anion exchange water filters are also economical filtration solutions. The cost of their maintenance is relatively low thanks to the low costs of regeneration chemicals. They regenerate automatically owing to the automatic meters or clocks attached to their control valve. Additional advantages include:
- Quick and uncomplicated installation process.
- Hasty results.
- Diverse tank sizes and production capacities.
- Removal of numerous impurities like organic compounds, silicon, and nitrates.
➣What Types of Anion Exchange Water Filters do You Provide?
Anion exchange water filters are mostly used in distinct applications. To exclusively satisfy the demands of each application they are manufactured in different versions. The difference is mainly accounted for by the distinction in resin type. Here are the two primary types of anion exchange water filters provided by NEWater.
● Strong base anion exchangers.
Strong base anion resins are principally employed in dealkalization, TOC removal, demineralization, and desilication applications. They are further divided into Type 1, Type 2, and macro-porous strong base anion resins. The Type I resins are chiefly used to selectively eradicate traces of nitrates (NO3-), perchlorate (ClO4-), and sulfates (SO3-). Type 2 resins are primarily used to effectively remove anionic pollutants.
● Weak base anion exchangers.
Weak base anion exchangers are characteristically recharged using sodium carbonate (Na2CO3), ammonia (NH3), or sodium hydroxide (NaOH). They utilize amine functional groups and rarely have exchangeable ions. Their primary applications include partial deionization and TOC elimination. They are however quite ineffective in eradicating weak acids like silica.
➣Which Impurities Are Removed by Anion Exchange Water Filters?
Anion exchange water filters are typically exploited to selectively eliminate anionic pollutants from raw water. The distinct types of anion exchange filters i.e. strong base and weak base anion resins are deployed in varied applications to eradicate distinct contaminants. Primarily, anion exchange water filters are utilized to effectively remove Total Organic Compounds (TOCs), nitrates (NO3-), and silica. Underneath is a comprehensive list of anionic impurities eliminated by anion exchange water filters.
- Sulfate (SO4-).
- Nitrate (NO3-).
- Bicarbonate (HCO3-).
- Arsenic and perchlorate.
- Carbonate (CO3-).
➣Is it Safe to Drink Water Generated by Anion Exchange Water Filters?
Well, anion exchange water filters eliminate harmful anionic pollutants such as nitrate, organics, silica, and arsenic. They do decrease the nitrate level to 10 mg/L or lower, which is the threshold set by most health and environmental regulators like the EPA. However, they do not eliminate non-ionic impurities, which can be harmful to the human body when consumed.
As such, the deployment of anion exchange water filters in treating drinking water mandates a supplemental system. A reverse osmosis system, for instance, could eradicate non-anionic impurities including pathogens and cationic minerals. You can however treat your drinking using an anion exchange water filter by selectively employing it to filter feed water composed of only anionic contaminants.
➣What Factors Should I Consider When Buying Anion Exchange Water Filters?
Purchasing an anion exchange water filter or any other water treatment equipment can be a straightforward task when you arm yourself with the necessary information. A comprehensive understanding of the prospective feed water and the varied types of water filters will massively guide your selection process. Beneath are some of the most important questions you need to ask yourself when purchasing anion exchange water filters.
● What pollutants are in your feedwater?
Anion exchange water filters are chiefly exploited as selective treatment solutions that target anionic pollutants. By testing samples of your prospective feed water, you will establish the contaminants that need removal and the perfect filtration system and mechanism.
● What is the intended use of filtered water?
Be aware of the quality of water your prospective application demands. This will aid you in selecting the perfect post-treatment system to supplement your anion exchange water filter. It will also help you comply with the existing quality regulations.
● How Much Water Do You need?
Evaluate the tank size, service flow rate, and exchange capacity to establish the right anion exchange filter that will match the scale of your application. You can even order a customized filter to make certain your quantity requirements are duly met.
➣What is the Difference Between Anion Exchange Filters and Cation Exchange Filters?
Cation and anion exchange water filters are principally distinguished by the charges attached to their active sites and the ionic impurities they eliminate. While anion exchange water filters are specifically used to remove negatively charged constituents, cation exchange filters are solely utilized to eradicate positively charged constituents. Nonetheless, both filters can be jointly used as is in the case of mixed-bed ion exchangers to optimally deionize water.
Cation exchange filters have their resins charged with hydrogen (H+), sodium ((Na+), or potassium (K+) ions, and their primary applications include water softening and partial deionization. Anion exchange filters on the other hand have their resins charged with chloride (Cl-) or hydroxide (0H-) ions. Their principal application sectors include desilication, nitrate removal, and TOC reduction.
Anion exchange water filters are commonly regenerated using caustic soda (NaOH), sodium carbonate (Na2CO3), ammonia (NH3), or lime. Cation exchange water filters are recharged using hydrochloric acid or sulphuric acid. They however utilize the ion-exchange process to eliminate undesired ionic pollutants from water. In demineralization applications, they are more effective when deployed jointly.
