Practical Applications of Highly Alkaline Electrolyzed Ionized Water in Manufacturing: Semiconductor Component Cleaning, CNC Machine Tool Antibacterial and Deodorizing

Power Micro International Co., Ltd. developed a patented system that generates a single-phase pH 13.2 alkaline solution with no chemical additives.
It produces no acidic water, chlorine gas, or wastewater, meeting ESG low-carbon standards.
The electrolyzed water has strong penetration and reduction potential, decomposing oils and suppressing bacteria.
Smaller molecular clusters and lower surface tension enhance cleaning and cooling performance.
Daily output reaches 80 L of pH 13.2 water (equivalent to 400 L at pH 12.5) with low operating cost and simple maintenance.

◆ Mechanism

  • The high hydroxide ion concentration and low oxidation-reduction potential give the water its powerful degreasing, organic decomposition, and antibacterial capabilities while preventing biofilm formation.
  • Power Micro’s high-alkaline electrolyzed ionized water has been verified using ATP(Adenosine Triphosphate Test) bioluminescence testing.
    ATP is the universal energy molecule in all living cells (bacteria, fungi, plants, animals). When luciferase reacts with ATP, it produces measurable light, allowing rapid assessment of microbial activity.
    Readings are expressed in RLU (Relative Light Units), where higher values indicate higher microbial presence.

    Field tests showed that after cleaning with the electrolyzed water, ATP residual levels dropped by more than 90%, demonstrating strong antibacterial, cleaning, and biofilm reduction performance.


Client A:Semiconductor Cleaning Application

In semiconductor manufacturing, cleaning represents over 30% of the process. DI water removes particles, metal ions, and organics, but cannot alone meet today’s efficiency and ESG requirements.
Combining it with high-alkaline electrolyzed water significantly enhances cleaning and penetration without chemicals.

Key applications: particle and organic film removal, metal ion neutralization, and optical/MEMS surface cleaning.


Client B:Application of antibacterial and deodorizing CNC machining cutting fluids

Coolant odor arises from bacterial growth and oil-water separation, producing sulfur and amine gases due to impure water, low concentration, or poor maintenance.

Real-World Applications & Integration : Applied in coolant mixing (3–10%), machine/tank cleaning, part rinsing, and mist deodorization, it suppresses bacteria, extends coolant life, and neutralizes fumes

Field Performance & Results : Field use shows 15–25% longer tool life, 2–3× coolant cycle extension, and 30–40% less coolant and waste. A thin film on ferrous metals provides temporary rust protection.

  • No chlorine gas or wastewater

  • Smaller molecular clusters → better penetration & cooling

  • Negative ions encapsulate oils → strong degreasing & odor removal

  • Extended tool life, reduced coolant and waste

  • Rust-prevention benefit for process stability

  • Easy maintenance and low cost

  • 80 L/day output (equivalent to 400 L at pH 12.5)


Q1:Can it be mixed directly with cutting fluids ?

Yes. It can be added at a concentration of 3–10% to inhibit bacterial growth, eliminate odor, and stabilize pH.
Mixing with acidic or chlorine-based additives is not recommended.


Q2:Can it be used in semiconductor processes

Yes. High-alkaline electrolyzed water can be mixed with DI water for cleaning semiconductor parts or substrates.
However, concentration control is required to avoid static charge residue during processing.

Q3:How should the high-alkaline electrolyzed water system be maintained

Only regular filter replacement and electrode inspection are needed.
Operation is simple, and the consumable cost is very low
