What is Ion Exchange Water Treatment Process and How does it Work?

Ion Exchange (IX) is a reversible chemical water treatment process for selective removal of charged inorganic species from water using an ion-specific resin and replacing them with other similarly charged ions. As water containing undesired ions passes through a column of resin media, charged ions on the resin surface are exchanged with the undesired ions in the water. In a large centralized treatment system, the resin is regenerated, and a regenerant waste stream is discharged. For Point-of- Use (POU) treatment units, the resin is replaced periodically as opposed to regenerating. One of the most common applications of the IX principle is water softeners which is used to remove excess hardness causing minerals such as calcium and magnesium from the water. IX process is also used for removal of heavy metals such as copper, lead, barium, cadmium, and radionuclides such as radium and thallium. 

Groundwater sources can contain certain quantities of natural radionuclides that result from the decay of Uranium, Radium, and Thorium isotopes in addition to minerals such as calcium and magnesium that results in high hardness. Since, the water supply in Dubai comes from two primary sources – seawater and groundwater wells, it is crucial that additional treatment methods be implemented to make the water safe for human consumption. This article discusses the characteristics and benefits of the POU IX system by 3M – 3MWTS Water Softener Series. 

Product Features & Benefits of 3M™ AQUA-PURE™ 3MWTS SERIES WATER SOFTENING SYSTEMS

3M offers a broad range of water filtration products for residential and commercial purposes. The WTS Series is a whole- house water filter system that is a great solution to help protect plumbing and appliances as well as offer great tasting drinking water from anywhere in the home. The WTS Series include three water softening systems that address the very common water quality concerns of hardness, iron, inorganics, and radionuclides such as Barium and Radium. The 3MWTS series is WQA certified, NSF/ANSI Standard 44 listing for reduction of Barium, Radium as well as Water hardness. It is optimized for Iron, Manganese, and Hydrogen Sulfide reduction. 

 

Some of the common applications of this product line are water treatment/softening for drinking purposes, water conditioning for bathing, water conditioning for spots and hardness buildup on dishes, glassware, water conditioning to increase life of appliances, and save energy costs. The three products are listed as follows: 

  1. 3M™ Water Softener System 3MWTS150-01
  2. 3M™ Whole House Water Softener System 3MWTS100-01
  3. 3M™ Water Treatment System Softener 3MWTS200-125-01

 
These series include a proprietary salt shelf, thus reducing service issues. The 3MWTS200-125 utilizes a full 1.25″ porting throughout the Resin Re-circulators as well as the valve, a true industry differentiated feature. The table below describes the reduction claims and flow rate provided by each of the three water systems in the WTS series.

The WTS Series from 3M offer a multitude of solutions to common water issues caused by scale formation due to excessive calcium, magnesium, red water issues caused due to iron, and severe health issues such as increased blood pressure, difficulty in breathing, stomach irritation, damage to kidney, liver, and spleen. The whole house filter system can provide a cost effective and long-term solution to easy access to clean drinking water.
