Ion Exchange Systems
AQUALITEK Ion Exchange systems provide high-performance, customizable ion exchange system solutions for residential, commercial and industrial water treatment. Reliable, efficient, and sustainable softening and deionization.
Two Bed Ion Exchange Deionizer for Industrial, Laboratory, and Boiler Feed Water Purification
A Water Deionizer is a specialized water purification system designed to remove dissolved ions, minerals, and contaminants from water through an ion exchange process. It effectively eliminates both cations (such as calcium, magnesium, sodium, and iron) and anions (such as chloride, sulfate, nitrate, and bicarbonate), resulting in high-purity deionized (DI) water.
Our Two Bed Deionized System is a reliable and cost-effective water treatment solution designed to produce high purity demineralized water. Using separate cation exchange resin and anion exchange resin columns, the system effectively removes dissolved salts, minerals, and impurities from raw water.
Mixed Bed Ion Exchange Deionizer | High Purity Water Treatment System for Ultrapure Applications
The Mixed Bed Deionizer (MBDI) is a highly efficient water purification system that combines cation and anion exchange resins in a single vessel. By ensuring intimate contact between resins, it achieves exceptionally low conductivity and silica levels, making it the preferred choice for producing ultrapure water.
Single or Dual Water Softener Systems
A water softener is a specialized filtration system designed to remove hardness-causing minerals, primarily calcium and magnesium, from water. Hard water can lead to scale buildup in pipes, appliances, and fixtures, reducing their efficiency and lifespan. By using an ion exchange process, water softeners replace these hardness minerals with sodium or potassium ions, effectively softening the water.
Water softeners are widely used in residential, commercial, and industrial applications to improve water quality, enhance appliance performance, and prevent plumbing issues. Softened water also provides benefits such as better lathering of soaps and detergents, reduced soap scum, and improved efficiency of water heaters and other appliances. With their ability to extend the life of plumbing systems and reduce maintenance costs, water softeners are an essential solution for managing hard water problems effectively.
Electrodeionization Systems to Get UltraPure Water
Electrodeionization (EDI) system is an advanced water purification technology that combines ion exchange and electrochemical processes to produce ultra-pure water. Unlike traditional deionization methods, which rely on chemical regeneration, EDI utilizes electric fields to drive the movement of ions through ion-exchange membranes, effectively removing dissolved salts and other ionic contaminants.
This process is continuous and does not require the use of chemicals for regeneration, making it an environmentally friendly and cost-effective solution for producing high-quality deionized water. EDI systems are widely used in applications requiring ultrapure water, such as in the pharmaceutical, semiconductor, power generation, and biotechnology industries, as well as for laboratory use.
By offering high-purity water without the need for chemical regeneration, EDI systems provide a sustainable, efficient, and reliable alternative to traditional deionization methods, making them an ideal choice for industries where water quality and process control are critical.

Solutions in Real-World Scenarios
Our solutions have been widely implemented across industries—from industrial manufacturing and municipal infrastructure to agricultural irrigation and commercial facilities. Here are some selected cases that demonstrate how we tailor water treatment systems to meet client needs, achieving goals such as energy efficiency, compliance, and water reuse.
Indonesian customers need a water treatment design for residential water purification. The water source is underground well water. After taking water samples for testing, it was found that the water turbidity was very
high and the iron content was also high, both of which exceeded the local limit. A water purification equipment was needed to reduce the turbidity and iron content.
Water sample turbidity: 56.6 NTU, local limit 25 NTU
Water sample iron content: 6.61 mg/L, local limit 1mg/L
Requirement: water turbidity and iron content below the limit, remove heavy metals, viruses and bacteria (E. coli), and the purified water should meets the standard of domestic water for daily use.Water flow: 36000LPH / 10LPS And also the whole system should be installed in a 20GP container, to
make it a mobile containerized water treatment system.
An industrial client in Ecuador required a reliable solution to pre-treat groundwater for production use. The raw water exhibited turbidity, sediment, and occasional odor, which posed a risk to downstream processes. The client sought a simple, automatic, and low-maintenance filtration system to improve water quality before further treatment or use. Water flow required at 20m3 per hour.
Cape Verde, an island nation off the coast of West Africa, faces seasonal freshwater scarcity due to limited natural water resources and increasing residential demand. A local utility company partnered with us to deploy a containerized seawater reverse osmosis (SWRO) system to provide reliable potable water for domestic use.
FAQs About Ion Exchange Systems
Ion Exchange Water Treatment Systems
How often is regeneration needed?
It depends on water quality and usage. Most systems regenerate every few days to a week under normal loads.
Which chemicals are required for regeneration?
Softening uses NaCl. Demineralization uses HCl or H₂SO₄ for cation resin and NaOH for anion resin.
What is the difference between softening and deionization?
Softening removes only hardness ions (Ca²⁺, Mg²⁺), while deionization removes both cations and anions to produce high-purity water.
Can ion exchange work with seawater or high-TDS water?
Ion exchange is more suitable for low to moderate TDS water. High-TDS applications often use RO as a primary treatment.
Are mixed bed systems better than two-bed systems?
Mixed bed polishers are used for final polishing after RO or two-bed deionization to achieve ultra-pure water.
