AQUALITEK Cooling Tower Deionized Water Treatment
AQUALITEK Cooling Tower Deionized Water Treatment
AQUALITEK Cooling Tower Deionized Water Treatment is a practical, reliable solution designed to protect cooling towers from scale, corrosion and biological build-up. Built for commercial and industrial sites, the system supplies high-quality deionized (DI) water that helps maintain heat transfer efficiency, reduce downtime, and lower operational costs.
How it works
The system uses a combination of pretreatment, ion exchange/deionization modules and simple monitoring to remove dissolved minerals and impurities from make-up water. Clean DI water reduces mineral deposits and limits corrosion on heat exchangers, piping and tower components. The design is compact, easy to install, and can be customized to fit existing cooling systems.
Key benefits
- Improved cooling efficiency — less fouling keeps heat transfer at peak performance.
- Lower maintenance costs — reduced scaling and corrosion mean fewer cleanings and repairs.
- Extended equipment life — protecting metal surfaces and coatings increases longevity.
- Reduced chemical use — DI water lowers the need for aggressive additives and biocides.
- Simple operation — user-friendly controls and monitoring make daily use easy.

FAQ
What is the difference between Reverse Osmosis (RO), Ultrafiltration (UF), and Nanofiltration (NF)?
1. Reverse Osmosis (RO): Removes up to 99.9% of contaminants, including salts, bacteria, viruses, and heavy metals.
2. Ultrafiltration (UF): Uses a membrane filtration process to remove bacteria and particles, while retaining essential minerals.
3. Nanofiltration (NF): Falls between RO and UF, removing some salts and organic compounds while allowing certain minerals to pass through.
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.
What types of water treatment systems does AQT offer?
AQT provides a wide range of water purification solutions, including reverse osmosis (RO) systems, ultrafiltration (UF) systems, nanofiltration (NF) systems, deionization (DI) systems, electro-deionization (EDI) systems, chemical dosing systems, and water softeners.

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.
