What is Chloramine?

How to Remove it from your Water

For decades, chlorine has been the chemical disinfectant additive of choice for municipal water utilities throughout the United States. Recent changes in the EPA’s Safe Drinking Water Act, however, are likely to adversely affect that traditional choice. The Act now includes the Stage 2 Disinfectants and Disinfection Byproducts Rule, which mandates stricter controls of byproducts like trihalomethanes (THM). THM results from the reaction of chlorine with naturally-occurring organics found in pipelines and delivery systems. The EPA now requires that municipalities measure THM and maintain minimum ppm within the water system. The chemical disinfectant additive of the future is likely to be chloramine (NH2Cl), an inorganic compound created when a small amount of ammonia is added to chlorine. Like chlorine, the new compound is effective as a primary disinfectant, or as a “shock” treatment. Since it doesn’t dissipate as readily as chlorine gas, the compound is able to disinfect even to the far ends of the municipal pipelines. This helps make NH2Cl a cost-effective alternative to chlorine. The downside, however, is that chloramines are believed to be carcinogenic. The possible carcinogenic effects, as well as the direct affects chloramines have on some food service delivery system parts and taste quality of beverages make chloramine removal an important consideration for food service companies. Standard carbon filters already in place are not effective because chloramines require substantially more of the highest-quality carbon for effective filtration. Additionally, chloramines need more contact time with carbon because the chloramines-carbon reaction is weak. chloramine reductionEverpure has a solution in its new chloramine filter products. The quick-change system offers a balanced particulate/chloramines reduction capacity that will prove cost-effective for food service companies. The CLM Chloramine Cartridge systems fit all existing QC heads, which allows an easy transition from current chlorine filtration to chloramine filter system. The highest-quality carbon is used as part of the chloramine removal cartridge system, with ratings balanced between particulate and chloramines removal. This allows food service groups to select the appropriate cartridge for their specific needs. The Everpure CLM products are designed to accommodate fountain beverage and combination systems.

Hydroblend Cuts Long-Run Costs

For applications in which water is heated past its boiling point, it is advisable to employ measures designed to reduce the level of lime and other minerals in the water service to safeguard against scale buildup in water boilers. Such buildup can lead to machinery damage, and if left unaddressed, failure. While the most common example of applications in which this is a concern is the brewing of coffee and other fine coffee beverages, the filtration of, and control of scale in, water used in steam equipment is extremely important. Because each piece of steam machinery, such as those used in the food service industry, by definition contains a boiler in which water is heated past its boiling point, harmful scale buildup will result if water used is not appropriately treated. There are two popular methods of addressing the presence of scale in a water supply, depending on whether scale has already formed or not. They are: Polyphosphate Granules

Generally used to clean boilers which have already suffered an amount of scale buildup, polyphosphate granules, such as Everpure’s proprietary formula “ScaleKleen,” remove limescale quickly, easily, and safely in an environmentally friendly manner from OCS brewers, steam, warewashing, and other equipment. Because activated citric acid is the typically the primary ingredient in these non-toxic blends, they are safer to skin and won’t burn clothing like conventional deliming acids. In addition, they are sewer system disposable, so you can pour it down the drain.

Hydroblend Scale Sticks

Hydroblend” scale sticks are the second component of a two-stage water filter designed by Everpure. Scale inhibitor feeders (scale sticks) reduce scale inline by dispensing a controlled amount of Hydroblend, a sophisticated blend of polyphosphate compound which inhibits scale. As such, scale sticks present in dual-filter systems designed for OCS brewers, steam, warewashing, and other applications significantly reduce scale inline, effectively preventing scale from ever forming.

While both methods are used in modern commercial settings, each approach has its advantages. Polyphosphates have been used in the prevention of mineral scale and corrosion control for years as a cost-effective method of controlling scale within a water supply. Hydroblend products on the other hand, are comparatively new, and marginally more expensive. There are however, several advantages. Hydroblend products are:

  • 100% active, so there is no residual product left over.
  • specifically designed to provide mineral scale prevention and corrosion control in high temperature and high hardness applications, while phosphate granules are not.
  • designed to ensure that the product feed rate is consistent over predictable time periods.
  • available in various configurations allowing it application to many different processes.

Regardless of which approach is used, it is important to monitor and control scale levels within a water supply. Doing so will prevent costly repairs and possible replacements.

Water Softening: A Simple Approach to Great-Tasting Water

“Hard water” is generally defined as that which has a high concentration (>100mg/L) of dissolved salts, like calcium and magnesium, which are absorbed from the earth. This excess of particulates can cause numerous problems for the home and small business owner, such as difficulty in regulating water pH (important for pool and aquarium owners), and scaling/deposit buildup in pipes, boilers, and machinery which makes use of water, such as coffee and espresso makers.  The classic tell-tale sign of hard water is difficulty in lathering soap and shampoo. Another such problem is the taste associated with hard water. Water containing mineral contaminants can taste bitter, especially when used to cook or brew fine coffee. When this becomes a concern, many turn to water softening to remove these minerals and make them palatable. Softening, while not a lengthy process, is complex when compared to other purification methods such as reverse osmosis. Water softener cartridges make use of either an all-in-one cartridge such as the Everpure ESO7 or a drop in bowl system such as Everpure’s SO-204 to remove excess minerals from your water. With the ESO 7, not only is water softened, but dirt and particles are removed as well.  The ESO 7’s unique three-stage blending cartridge provides softened, buffered, and precoat filtered water, while the cartridge’s ion exchange resin with buffering capabilities and high-capacity coconut carbon filtered water bypass make it the perfect choice for specialty coffee, espresso, and ice tea applications. Systems such SO-204 combine small size and ease of use with commercial application capability.   Measuring just 26”x5.125”x5.25”, the SO-204’s replacement cartridges are sized to fit under any counter or mounted on the wall behind the coffee or espresso machines.  While relatively small, the SO-204 is designed to handle water having up to 30 grains per gallon (500mg/L) – 5 times the definition of “hard” water.  Moreover, the filters are easy to change.  Not only do replacement cartridges not require a housing wrench to be changed, that is, they can be hand-tightened, but cartridges require only one minute of flushing.  Many high-end coffee and espresso machines require a water softener to ensure the quality of the coffee is preserved through the brewing process and warranty purposes. If you think you would like to make use of a water softening cartridge in either your home or business, contact Filter Pure Systems, Inc. at 1-800-942-7873 today.

Seawater/Brackish Water Reverse Osmosis

Reverse Osmosis, also known as hyper filtration, is the preferred method of seawater and brackish water purification. As the equipment needed to perform reverse osmosis is cost-effective, and the process requires little input energy compared to other methods of purification, reverse osmosis has become the worldwide leader among desalinization methods. Developed at UCLA, and used commercially since the 1970’s, seawater reverse osmosis has served marine professionals for nearly 40 years. Seawater Reverse Osmosis (SWRO) is used in a wide range of commercial applications. Marine professionals such as commercial fisherman and offshore rig workers rely on SWRO to provide freshwater for routine daily tasks such as bathing, cleaning and of course, drinking. In larger applications, such as cruise ships, SWRO is sometimes also used. In such applications, it is necessary not only to desalinize water, but to provide quality freshwater. Cruise liner restaurant professionals count on SWRO for water used for cooking, as well as making coffee, soda and other beverages. Here, consistency is key. By way of its simple yet effective design, reverse osmosis is able to consistently satisfy the needs of those who count on it. The process itself is relatively simple and straightforward. In order to purify a liquid, the “solvent” (in this case, water) is put under pressure in excess of 250 psi for brackish water and 1000 psi for seawater, forcing it through a semi-permeable membrane. This application-specific membrane allows water molecules to pass through, but catches “solutes,” yielding purified water. When employed, reverse osmosis is capable of not only of de-salting water, but also removing other impurities such as bacteria, ions and particulates. If you’re considering using reverse osmosis to address your water purification needs, browse our inventory of Everpure reverse osmosis filters.

Which Water Filter is Right for You?

Deciding on a water filtration system for your home or business can be daunting. There are numerous types of filters, each of which is manufactured by each different brand, totaling thousands of options for anyone looking to choose between them. We at Filter Pure Systems, Inc. have recognized this, and prepared a short preparatory question and answer guide to help you make your decision. The first and most important question to ask yourself when determining which filter to purchase is: “What do I need my water filter to do?” While the answer to this question may seem obvious enough, it’s likely not. Granted yes, at the end of the day, you want your filter to “filter” your water, but there’s much more to consider. Am I purchasing a water filtration system for my home or business? Water purifiers “run the gamut” of design. Generally speaking, units designed for commercial applications are larger than residential designs and are more expensive to maintain. In addition, they generally have specific applications not required in a residential setting. As a result, they are capable of handling more frequent use, satisfying the highest level of commercial demands. It’s advisable for these, among other, reasons to consider going commercial when purchasing a water filtration system. Such systems include the drinking water QL2-OW200L system, ice machine Insurice Single-i2000(2) system or fountain QC7I Single- MC2 system. Do I have a specific application for my water filtration system in mind?   It is important to determine exactly what your water filter it will be responsible for doing, before buying it, for two main reasons. First, if you have a specific application in mind, it may be necessary to purchase a unit designed to address this concern. Some water filtration units have built-in water softeners or de-mineralizers designed to yield a specific quality of water. This is desirable for many commercial settings, especially where the water is being used to make beverages such as coffee and soda espresso. Second, it may be that narrowing down the use of your unit will greatly reduce both upfront and ongoing costs. Generally speaking, the smaller demand put on your filtration system, the lower the cost of maintenance. If you decide that your system need only be used for part of your water supply, you are very likely to save money. How much water do I need, and how fast?   While this is typically only a concern in commercial applications, it may also be a useful question in residential applications where the filter is responsible for purifying the entire home’s water supply. Filters have their limits. Only a predetermined amount of water can successfully be processed by a unit in a given amount of time. This measurement is called “flow” or “flux.” While units with lower flow may be less expensive, they may require a little patience on the part of their user. Units with greater capacity for flow can provide more water in a shorter period of time, but are generally more expensive. There are many questions to ask yourself when considering a water filtration unit. If you would like help making your decision, or have already decided, give Filter Pure Systems, Inc. a call at 1-800-942-7873.
