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.
