تبادل یونی تصفیه آب

تبادل یونی یکی از اشکال پدیده جذب سطحی است، که در آن فاز سیال در تماس با فاز جامد جاذب قرار می‌گیرد. طی این تماس برخی از اجزای موجود در فاز سیال جذب فاز جامد شده و از سیال جدا می‌گردند. فرایند تبادل یونی فرایندی برگشت پذیر است که طی آن یون های خارجی موجود در آب جذب گروه های عاملی قرار گرفته بر روی شبکه پلیمری (فاز جامد) می‌گردند و بدین ترتیب آب عاری از هرگونه ناخالصی یونی حاصل می‌گردد.

پس از اشباع شدن گروه های عاملی، سیستم تحت عملیات بازیابی و شستشوی شیمیایی قرار گرفته و مجدداً مورد استفاده قرار می‌گیرد.

تصفیه آب به روش سیستم تبادل یونی

از سیستم های تبادل یونی به دو منظور سختی گیری و همچنین تولید آب با خلوص بالاتر استفاده می شود که به طور جداگانه در ذیل اشاره می گردد. سیستم های تبادل یونی به عنوان سختی گیر آب مورد نیاز صنعت به لحاظ استاندارد با آب مورد نیاز شرب بسیار متفاوت می‌‌باشد.

Ion exchange is a form of adsorption phenomena, where the liquid phase is in contact with the solid phase adsorbents. The back some of the components in the solid phase and liquid phase adsorption fluid apart. The ion exchange process is reversible process in which foreign ions in the water absorption of the functional groups on the polymer network (solid phase) and are thus devoid of any impurity ion water is obtained.

After saturation of functional groups, chemical cleaning system is located under the recovery and re-used.

Ion exchange softening systems to the order and the production of high purity water used separately mentioned below. Ion exchange water softener systems as standard with industry requirements in terms of water needed for drinking is very different.

Industry is the most important thing in water to remove minerals that can be provided in terms of their deposits. One of the most renowned water, produce steam, which in the presence of sediment in the water can be reduced lifetime of the facility.

Most of these deposits are known as hard. The scientific definition of all cations with electric capacity of a hard to say. Therefore, in most industries only remove water hardness is concerned that the cost of water to remove all the ions are much lower.

The specific ion exchange systems have been produced for this purpose are known to sodium base resin. In fact, these resins, water hardness ions such as calcium, magnesium and sodium absorption and instead released it.

Note that in this way the total anions and cations in the water remains constant and only changes are the type of ions. A limitation of this method is not accountable for TDS in 1000 and have used other methods. Revival of the softeners is a salt and water solution.
