Here is the info on the filter
The filter uses a combination of different technologies to help disperse the mineral scale. First, the primary active ingredient used to prevent scaling is a low molecular weight polyacrylate. This chemistry has been used in steam boilers. The active chemistry is very safe and non-toxic. Polyacrylate is used in diapers and many other common products used daily. Polyacylate is a polymer which use charge modification to disperse scale forming minerals such as calcium carbonate. The chemical is slowly released by using our patented Smart Release technology. Our company has patented various polymer coatings and membrane materials for slowly and consistently releasing dry over a defined set of conditions (flow, temperature, etc). The principle of controlled release is based on osmotic pressure. The active ingredients are covered with a semi-permeable polymer coating. This coating lets water inside the coating which turns the dry chemical into a slurry or sludge. This creates a very high concentration of chemistry inside the coating and since water always wants to be in a state of equilibrium, osmotic pressure forms inside the coating which then starts to push the chemical out of the polymer coating. The polymer coating then restricts how fast the chemical can release into the system. This produces a nice, linear controlled stream of chemical applied with the flow of the water. As you can tell, there has been a significant amount of R&D that has gone into this technology. Our company has been developing similar products and technologies used in heavy duty diesel engines and cooling towers for the last 7-10 years. for +20 years. It’s used for prevention of mineral scale in , once through systems, and
Now, here is the important part. As long as water consistently touches the areas of heat transfer and stays wetted, the scale inhibitor will disperse the scale forming minerals. Additionally, the water flow is a once through system which means there is little to no concentrating effect in the water which lowers the potential for scaling conditions to occur in the first place. In areas that do not consistently get wet – example over spray areas, there will be a slight build up of all the minerals in the water from simple evaporation. If the water completely evaporates to dryness, all of the minerals in the water have to go somewhere – this is not a chemical issue or problem. The chemical dispersant tries to tie up the calcium in the form of calcium acrylate as opposed to calcium carbonate. This material is easier to clean than calcium carbonate mineral scale. But the key is keeping areas wetted. Areas that consistently get wetted should not scale up due to the once through nature of the system design in combination of the scale preventing chemicals added to the water. Again, this chemical technology has been in existence for many years, the main difference is the controlled release technology we developed to slowly and consistently treat the water stream in an economical manner.
I hope this helps. I have attached a power point slide which illustrates the release of the active chemical compound. Let me know what other questions you may have.
