Cooling Tower Deionized Water Treatment Solutions | AQUALITEK
AQUALITEK Cooling Tower Deionized Water Treatment — Overview
AQUALITEK Water Treatment Technologies Co., Ltd., headquartered in Guangzhou, China, offers industry-leading Cooling Tower Deionized Water Treatment systems designed to protect heat-exchange surfaces, reduce fouling, and extend equipment life. Our systems combine precision deionization with robust monitoring and modular designs to deliver reliable low-conductivity water for industrial and commercial cooling towers.
Why Deionized Water for Cooling Towers?
Cooling Tower Deionized Water Treatment significantly lowers ionic content, minimizing scale formation, corrosion, and biofouling risks. By controlling conductivity and silica levels, AQUALITEK solutions improve thermal efficiency and reduce downtime, delivering measurable performance gains and lower chemical consumption for operators.
Key Features and Technology
Our deionized water offerings integrate high-efficiency pretreatment, reverse osmosis (when required), mixed-bed ion exchange, and automated conductivity controllers. Features include online sensors, PLC-based control, regenerable resin options, and compact skid-mounted units. These technologies ensure consistent water quality and simple integration into existing cooling tower systems.
Applications & Custom Solutions
AQUALITEK Cooling Tower Deionized Water Treatment systems serve power plants, HVAC central plants, manufacturing facilities, and data centers. We provide tailor-made packages—from complete new installations to retrofit modules and component supply—ensuring compatibility with local water sources and operational requirements worldwide.
Sustainability & Cost Savings
Our designs prioritize resource efficiency: reduced blowdown, lower chemical dosing, and optimized water reuse help cut operating costs and environmental impact. AQUALITEK’s systems deliver long-term ROI through extended equipment life, reduced energy consumption, and minimized waste streams.
Service, Support & Parts
AQUALITEK supports customers with engineering design, commissioning, scheduled maintenance, resin regeneration services, and genuine spare parts. Our global partners benefit from responsive technical support and lifecycle programs that keep Cooling Tower Deionized Water Treatment systems performing at peak efficiency.
Which chemicals are required for regeneration?
Softening uses NaCl. Demineralization uses HCl or H₂SO₄ for cation resin and NaOH for anion resin.
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 industries does AQT serve?
We provide water treatment solutions for a wide range of industries, including:
1. Industrial Manufacturing – Process water treatment, cooling water, and boiler feed.
2. Hospitality & Commercial – Hotels, restaurants, and office buildings.
3. Residential Applications – Drinking water purification and softening.
4. Healthcare & Pharmaceuticals – Ultra-pure water for laboratories and hospitals.
5. Municipal & Public Utilities – Water supply and wastewater treatment.
6. Food & Beverage Processing – Filtration for beverage p
Do softener systems remove iron or chlorine?
Not typically. If your water contains iron, manganese, or chlorine, consider a dual-system setup or add specialized pre-filters.
