Dec 18, 2017· Ion exchange (IX) resins are often highly effective for removing hardness, alkalinity, chloride, mercury, and organics, among other contaminants. While they can offer some efficiencies over other treatment technologies, they also call for specific maintenance processes. With proper care, IX resins can deliver consistent results and have a long service life, making them well …

foulant and the ion-exchange resin have more cor-relation regarding resin fouling than whether the resin is a gel or macropore. Some equipment manufacturers believe that pre-treatment is the proper method for dealing with organic-bearing waters and that the use of a "work-ing ion-exchange resin" to accomplish organic
The utility of ion exchange rests with the ability to use and reuse the ion exchange material. Ion exchange occurs in a variety of substances, and it has been used on an industrial basis since about 1910 with the introduction of water softening using natural and, later, synthetic zeolites.

Toufiq .M ...
Aug 26, 2010· To design a co-current or counter-current pla nt, determine the resin operating capacity based on a set of operating conditions and then apply correction factors for the specific conditions of the design. - First, you have to have feed water quality analysis. Determine Hardness Concentration and TDS concentration of feed water in ppm as CaCO3.
Nov 17, 2015· Ion exchange: which resin should I choose for my water softener? November 17, 2015. Question: If you are researching water softener options you may have read about the different types of resin that can be used in a softening system.
The ion exchange process is based on the fact that like charges repel one another and opposite charges attract. An ion exchange water softener exchanges the hardness minerals (calcium and magnesium) dissolved in water for sodium. This soft mineral is contained on the softener resin beads and does not build up on surfaces as scale deposits.
In an ion exchange water softener, hardness ions in the water - primarily calcium and magnesium - are exchanged on the ion exchange resin for sodium. When all available exchange sites are converted from sodium to hardness, the softener is exhausted and needs to be regenerated.

It is recommended to soak ion exchange resins in demineralised water overnight before placing the ion exchange resins in service. This is especially important for anion exchange resins to make sure they are fully hydrated and for inert resin to reduce their hydrophobicity. This operation is used to minimize the floating and potential loss of these resins if they are backwashed before the first ...
The softening resin is also an ion exchange media. In a water softener, the resin bead acts as a cation (positively charged ions) to attract ions of the opposite charge (negative). In this case, the brine solution in a water softener is run through the ion exchange resin, which attracts the negatively charged sodium ion in the solution.

Ion exchange is a Reverseible process in which ions are released from an insoluble permanent material (resin) in exchange for other ions in a surrounding solution; the direction of the exchange depends upon the affinities of the ion exchanger for the ions present, and the concentration of the ions in the solution.
Design Calculation For Softener Unit Client :- Techpro By Samar Seth About the Paper I,as an intern, calculated the ion exchange softener design for a small sized powerplant of TechPro Inc. in May 2015, and would like to share the calculations in the form of this research paper .
Sodium chloride is used as the regenerant chemical for converting exhausted softener resin back to the sodium form. The resin exchanges the collected hardness on the bead with the sodium ion present in the sodium chloride. It is applied to the bed at a concentration of 8 to 12%; usually, 10% is the norm. A contact time of 30 minutes is desirable.
How to calculate the volume of cation resin required vs the volume of softener size for a given flow rate? ... Ion exchange resins have a capacity of approximately 1 equivalent per liter of resin ...
Ion exchange occurs when raw water ions diffuse into the bead structure and exchange for the mobile portion of the functional group. Ions displaced from the bead diffuse back into the water solution. CLASSIFICATIONS OF ION EXCHANGE RESINS. Ionizable groups attached to the resin bead determine the functional capability of the resin.

Regenerating the resin bed refreshes its ability to exchange ions. Output Between Regeneration (OBR) Formula : (in m 3) Resin Quantity * Exchange Capacity/Hardness. Softener Resin : Ion exchange resins are polymers that have the capacity to exchange ions with ions in a solution that is passed through them. The use of ion exchange resins servesa ...
Ion Exchange Resins. Ion exchange (IX) resins are polymers that are capable of exchanging ions with ions in a solution that is passed through them. Our world-class IX resins serve applications as diverse as industrial water softening, pharmaceutical formulations, sweetener purification, mining and more.
Ion-exchange softeners are used extensively in small water systems and individual homes apart from Industry. Ion-exchange resin, exchanges one ion from the water being treated for another ion that is in the resin (sodium is one component of softening salt, with chlorine being the other). Ion Exchange resin exchanges sodium for calcium and ...
Softeners: Ion exchange water softening products remove calcium and magnesium from hard water to produce softened water. A water softener uses sodium to help replace calcium and magnesium ions. Unlike hard water, softened water will not leave any residue or scale on contact surfaces.
Oct 13, 2010· Ion exchange water softening is an inexpensive method for improving a home's water quality and preventing costly plumbing repairs. Water softeners are low-maintenance, and the cation resin has a working life of seven to 10 years before replacement is required. Iron …
The hardness ions Ca & Mg are taken up by resin and in exchange sodium ions are relinquished from the resin. Raw water will continue to get softened till the resin gets exhausted. Bringing back the resin to it original form is called regeneration. Softener resin is regenerated by sodium chloride (NaCl) of 10 -15% Concentration.
Softening of Water. The only time tested and proven method to soften water is to remove the Calcium and Magnesium ions from the incoming hard water in your home. This is called ION exchange method. There have been many attempts to get away from this process all over the world but without success.
An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25–0.5 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Jan 19, 2010· One of the most common product concerns for users of ion exchange resin is the leaching of organic compounds from the resin itself. The impact of leaching from ion exchange resins varies from industry to industry.For example, in home water softeners, color throw from ion exchange resins is usually a temporary aesthetic
