SOFT-TEC® COMMERCIAL / INDUSTRIAL WATER CONDITIONER APPLICATIONS Commercial Applications Condominium Apartment buildings Assisted Living Facilities Hotels Hospitals Office Buildings Schools Gas Stations Health Clubs SOFT-TEC® COMMERCIAL/INDUSTRIAL WATER CONDITIONER SCALE CONTROL SYSTEM PROCESS Industrial Applications Paint Booths Process Water Aerospace Food Processing Bottling Plants Cooling Tower Electronics The Soft-Tec® water conditioner control harmful dissolved lime from water via ‘’template induced or epitaxial crystallization’’. The water conditioner media surface accelerates the natural tendency of dissolved lime to crystallize, but does so before lime can deposit on pipes/surfaces further downstream. The composition of the Soft-Tec® Water Conditioner Media surface mimics that of calcium carbonate crystals, allowing the dissolved lime in hard water to form microscopic hard crystals of “activated lime” on the media surface via the process of “template induced or epitaxial nucleation.” The Soft-Tec® Water Conditioner Media returns lime to the water as stabilized crystals of “activated lime”. Once the microscopic crystals of activated lime grow large enough, they are freed from the Soft-Tec® Water Conditioner Media surface by shear forces of water flow. This makes room for generation of new activated lime crystals. These activated lime crystals are “stabilized,” and will not cause pipe scaling or stubborn lime deposits on surfaces. When the Soft-Tec® Water Conditioner Media-treated water dries on surfaces, these crystals form a fine, dusty residue that is easily wiped off without cleansers. The Soft-Tec® Water Conditioner Media’s produce “activated” crystals then remove pre-existing scale and prevent new scale formation. Calcium carbonate in pre-existing scale will slowly “redistribute” itself from the low-surface area of pipe surfaces and plumbing to the high surface area of all the crystals in solution. The trillions of microscopic crystals of activated lime provide an incredibly high total surface area for further epitaxial crystallization. The net result is removal of pre-existing lime scale from plumbing, keeping pipes and appliances lime-free whilst leaving a thin protective surface!
SOFT-TEC® COMMERCIAL / INDUSTRIAL WATER CONDITIONER PROCESS The Soft-Tec® scale control system’s reliability transforms the positively charged calcium ions into calcium crystals. These calcium crystals are stable and cannot attach to any surfaces and hardware as the calcium crystals are rinsed away by the water flow. The size of the calcium crystals bonds is so small that they can only be seen with a microscope therefore the effect is the same as if the water was completely free of calcium. Tests lasting several years prove that these calcium crystals cannot attach to any kind of surface and the result was 100% scale control and prevention. Also other ions can no longer attach to surfaces because of the structure of the surface created by the Soft-Tec® hardness stabilizer. The corrosion prevention works by adding a 30-micron protective layer to the surface of existing pipes and hardware. The Soft-Tec® specifications are calculated based on 75 grains per gallon or less. The Soft-Tec® hardness stabilizer has a warranty of 5 years on all components and the complete system from defective components and workmanship. The maximum level of chlorine in your potable water supply must not exceed 3.0 ppm. All iron, hydrogen sulfide, and tannins must be removed prior to water flowing through Soft-Tec® scale control water conditioner.
WATER CHEMISTRY REQUIREMENTS AFTER PRE-TREATMENT New Copper Pipe Installation When new copper pipe is installed must wait 60 days prior to install. Because the new copper pipe has the potential of leaching copper into the water until it has a chance to build up a patina. The time required for this varies greatly from a few days to 60 days depending on water chemistry and how much damage was done to the plumbing system by the excessive use of corrosive flux in the soldering process. Temperature The seed crystals that are produced by the media will continue to grow or partially re-dissolve depending on changes of Langelier Saturation Index of the water. Temperature is one of five parameters that are factors in LSI. Hardness: 0 - 75 GPG Temperature: 36 – 122˚F (2 - 50˚C) Pressure: 40-100 psi Chlorine: < 3.0 ppm Iron: 0.0 ppm Sulphur: 0.0 ppm Manganese: 0.0 ppm Phosphate: 0.0 ppm
SOFT-TEC® COMMERCIAL / INDUSTRIAL WATER CONDITIONER PROCESS LSI = pH - pHs pH is the measured water pH pHs is the pH at saturation in calcite or calcium carbonate and is defined as: pHs = (9.3 + A + B) – (C + D) Whereas A = (Log10 [TDS] – 1) / 10 B = -13.12 x Log10 (°C + 273) + 34.55 C = Log10 [Ca2+ as CaCO3] – 0.4 D = Log10 [alkalinity as CaCO3] Langelier Saturation Index The Langelier Saturation Index (LSI) is a formula that was devised by Professor Wilfred F. Langelier (1886-1981) in order to quantify the propensity of a given source water to forming scale or corroding plumbing systems (and thereby leaching metals from plumbing components and fixtures into drinking water etcetera). The formula is based on the concept of ‘’Water Balance’’ or ‘’Saturation’’ where the carbonic acid (H2CO3) and the calcium carbonate (CaCO3) present in the water are in a perfect state of equilibrium. The Soft-Tec® salt and chemical free scale control media requires the presence of ‘’available’’ or ‘’excess’’ calcium in order to produce and release the seed crystals into the treated water which then serve as nucleation sites for precipitating calcium further down the plumbing system. In order to calculate the LSI, it is necessary to know the alkalinity (mg/l as CaCO3), the calcium hardness (mg/l Ca2+ as CaCO3), the total dissolved solids (mg/l TDS), the actual pH and the temperature of the water (°C). LSI is defined as: As indicated above, the Soft-Tec® media requires available calcium to promote the formation of seed crystals. It can only do so reliably if it can induce the precipitation of calcium from a dissolved state into calcium carbonate crystal formations. Therefore, without proper pretreatment, the Soft-Tec® media should only be applied to treat water that has a neutral or positive LSI. Any method that would shift any of the parameters that are inputs into the LSI upwards (i.e. raising the pH, alkalinity or temperature etc.) would be acceptable methods. For the purposes of water treatment, however, the most common approaches are aeration and/ or pretreatment with a neutralizer like calcite or dolomite to bring the water into a balanced state. Indeed, when used with corrosive water without pretreatment, the Soft-Tec® media itself will suffer the corrosive effects of the water and the functional surface will be dissolved over time rendering the media ineffective. The formula above will return values > above and < below zero. The interpretation of the results are as follows: LSI INDICATION LSI < 0 Water is under saturated with respect to calcium carbonated LSI = 0 Water is considered to be neutral. Neither Scale Forming nor Scale Removal LSI > 0 Water is supersaturated with respect to calcium carbonate and Scale Forming may occur - 2.0 < - 0.5 Serious Corrosion but Non Scale Forming - .5 < - 0 Slightly corrosive but Non Scale Forming LSI = 0.0 Balanced but pitting corrosion possible 0.0 < 0.5 Slightly Scale Forming and possibly corrosive 0.5 < 2.0 Scale Forming but non corrosive
Soft-Tec® used the testing protocol of DVGW through an independent laboratory. DVGW is recognized throughout Europe like NSF in North America. The test was done by running raw 20gpg hardness water at 80˚C for continuous 21 days and then water with same properties treated by Soft-Tec® media was ran for 21 days. The comparison of Calcium scale proves the proficiency more than 99%. 21 Days Soft-Tec® Treated Water After 90 Days Soft-Tec® Treated Water 21 Days Raw Water (20gpg) After 90 Days Untreated Water SOFT-TEC® COMMERCIAL / INDUSTRIAL WATER CONDITIONER TESTING
