These included a slight increase in pH value and a decrease in Electrical Conductivity (EC) and Total Dissolved Solids (TDS). Density, viscosity and surface tension were also reduced, indicating weaker intermolecular forces in water after magnetization. In addition, the concentrations of dissolved ions (Na⁺, K⁺, Ca²⁺, Mg²⁺, Cl⁻, SO₄²⁻, NO₃⁻) generally decreased, supporting the hypothesis of molecular structure rearrangement in water. From a practical perspective, contact angle and capillarity tests revealed an increase in water wetting and spreading capacity, while the evaporation rate increased by about 20%, reflecting changes in the physical behavior of water. As for turbidity, placing a replaceable clamp with a fine filter at the outlet of the magnetization device was an effective solution to remove dust and silt. From an environmental standpoint, the magnetization device clearly outperformed in reducing the carbon footprint, with a carbon intensity of 0.021 g CO₂e/L compared to 1.201 g CO₂e/L for the household Reverse Osmosis (RO) unit-meaning that the magnetization device emitted about 57 times less. This makes it a promising, eco-friendly and energy-saving alternative for water treatment.
