Introduction
On March 26, 2025, EHisen Metal held a high-level technical exchange meeting with Singaporean clients, focusing on in-depth discussions about technological innovation, performance optimization, and market applications of titanium anodes in cooling tower water treatment.
Through academic exchanges and on-site factory visits, the partnership was further strengthened, laying a solid foundation for future in-depth cooperation.
1. Academic Discussion: Focusing on Anode Technology, Exploring Industry Frontiers
At the morning technical seminar, EHisen Metal's Technical Director, Mr. Wu, first provided Singaporean clients with a detailed introduction to the company's latest R&D achievements in titanium anode technology. Mr. Wu noted, "With increasingly stringent global environmental requirements, titanium anodes are gradually replacing traditional anode materials due to their superior performance, becoming the new favorite in the water treatment industry."

Advantages of Titanium Anodes:
Strong corrosion resistance: Titanium anodes perform exceptionally well in high-temperature, high-salinity, and highly acidic/alkaline environments, making them particularly suitable for harsh cooling tower water treatment conditions.
Long lifespan and low energy consumption: Compared to traditional anodes, titanium anodes offer higher electrolysis efficiency, significantly reducing operational costs.
Eco-friendly: No heavy metal leaching, compliant with international environmental standards (e.g., RoHS, REACH).
Breakthroughs in Coating Technology:
EHisen's independently developed IrO2-Ta2O5 mixed oxide coating further enhances the catalytic activity and stability of titanium anodes.
To address the high chloride-ion water quality issue raised by Singaporean clients, the technical team proposed a customized coating formula solution.
Expanding Application Scenarios:
Both parties explored potential collaboration opportunities for titanium anodes in seawater cooling systems and industrial circulating water treatment.
2. Factory and Laboratory Tour: Witnessing Quality, Strengthening Trust
Clients Amazed by Cutting-Edge Laboratory Equipment
During the technical exchange between EHisen Metal and Singaporean clients, the most remarkable segment was the in-depth inspection of the intelligent laboratory. As the core support for titanium anode R&D, EHisen's laboratory features internationally advanced multi-element water quality detection systems capable of testing 20 elements simultaneously, along with cutting-edge material characterization equipment to ensure comprehensive product performance.This "high-tech-packed" tour left clients exclaiming, "The full-chain control-from water quality analysis to material microstructure-truly demonstrates what a technological barrier is!"
On-Site Factory Inspection: Witnessing the Entire Quality Manufacturing Process
During the afternoon factory tour, the delegation visited:
Raw Material Warehouse
The raw material warehouse stocks only TA1/TA2 industrial-grade pure titanium. Each batch comes with supplier test reports, and we periodically send samples to BaoTi Testing Center for verification. Surface inspections are also conducted before storage to prevent material defects from affecting the precious metal coating.
Sandblasting Room
Sandblasting increases the surface roughness (Ra 3.5-5.0μm) of titanium substrates to enhance coating adhesion. Methods include dry/wet blasting with water sand (lower roughness for electroplating) or emery (higher roughness for brush-coated products).
Acid Pickling Room
Titanium substrates undergo HF+HNO₃ mixed acid pickling to remove oxide layers. The 3–5 minute process generates wastewater neutralized to pH 6–9, meeting environmental standards. Pickling activates surfaces for stronger precious metal bonding.
Mixing Room
Precious metal coating solutions are prepared here by professionals based on client parameters and technical specifications, with ±0.5% molar ratio accuracy. Magnetic stirrers prevent sedimentation, and solutions are only used after homogeneity confirmation to ensure coating stability.
Coating Room
Manual brush coating follows technical protocols to apply solutions in specified layers. This method excels for complex structures (e.g., mesh/tubular), with ≤±5% thickness deviation per layer. Real-time infrared drying inspections guarantee uniformity.
Sintering Room
Our gradient-temperature sintering under inert gas ensures optimal coating adhesion and longevity. Activated products undergo repeated sintering cycles to meet client-specified precious metal content.
Assembly Workshop
Custom titanium anode assembly includes laser-welding electrodes to conductive rods (contact resistance ≤0.8mΩ, 100% electrification tested). Custom structures accommodate client reactor designs.
Quality Inspection Room
This room tests product dimensions, coating adhesion/composition, and surface quality. Advanced tests are conducted at Baoji University or BaoTi Testing Center. Defective items are isolated for rework immediately.
The Singapore delegation highly praised EHisen's comprehensive production and quality control systems, stating, "The rigorous control at every stage-from raw materials to finished products-reflects the excellence we prioritize in partners."
3. Technical Focus: Why Titanium Anodes Are the 'Gold Standard' for Cooling Tower Water Treatment
In cooling towers' harsh conditions, traditional anodes fail rapidly due to high temperatures, salinity, and corrosion. Titanium anodes stand out with these advantages:
Extreme Environment Adaptability
Corrosion resistance: Titanium substrates with precious metal oxide coatings operate stably in extreme water conditions, preventing equipment damage.
Chloride resistance: For Southeast Asia's high chloride water (Cl⁻ >5000ppm), EHisen's gradient composite coating triples anode lifespan versus conventional materials.
Energy Efficiency
Tests show titanium anodes achieve 85% current efficiency (vs. 65% for traditional anodes), reducing energy consumption by 20–30%.
A petrochemical plant case study reported annual savings of >1.2 million RMB in electricity and 60% lower maintenance costs.
Eco-Friendliness & Compliance
Zero heavy metal leaching, compliant with EU RoHS/REACH standards, facilitates clients' ESG audits.
98% recyclability aligns with circular economy principles.
Feedback from a Singaporean client's Technical Director:
"EHisen's commitment-from water testing and small-batch trials to mass production, quality control, and technical support-exemplifies customer-centric values beyond our expectations!"
4. Scenario-Based Applications: How Titanium Anodes Solve Four Cooling Tower Pain Points
EHisen's global projects have validated titanium anodes' value in cooling towers:
Titanium anode electrochemical water treatment in circulating cooling systems achieves multi-faceted water quality control via innovative mechanisms.
During electrolysis, scaling ions (e.g., Ca²⁺/Mg²⁺) crystallize preferentially at the cathode and are removed by high-pressure water flow, preventing scale deposition on heat exchangers. It concurrently generates biocidal agents (e.g., hypochlorite, ozone, hydroxyl radicals) without chemicals, suppressing microbial/algal biofilm growth without corrosion risks.
For suspended solids, the electrochemical reactor's alternating acidic/alkaline microenvironments neutralize particle charges, enabling flocculation and settling. Automatic scrapers ensure efficient SS removal. Organic pollutants are decomposed via anode-generated reactive oxygen species, eliminating microbial nutrients and establishing a physico-chemical water stabilization system.
Future Outlook
This in-depth exchange strengthened EHisen Metal's collaboration with Singaporean clients. General Manager Mr. Lin stated, "This exchange deepened mutual technical trust and opened new opportunities in Southeast Asia. We anticipate long-term partnerships with Singaporean peers." Moving forward, we will uphold our "innovation-driven development" philosophy to enhance titanium anode performance and deliver superior water treatment solutions. We will also accelerate global expansion, collaborating with international partners to advance green water treatment technologies.
