SWIMdone ozone powder, used in swimming pool water treatment, releases nascent oxygen to oxidize chloramine into nitrogen, achieving rapid dechlorination and improved water quality. Its oxidation efficiency is influenced by multiple environmental factors, which indirectly or directly affect the oxidation process by altering the stability, reactivity, or form of chloramine.
Water temperature is one of the core factors affecting oxidation efficiency. At low temperatures, ozone solubility significantly increases, allowing for more complete dispersion in the pool water and increasing the opportunity for contact with chloramine, thus enhancing the oxidation reaction efficiency. For example, at water temperatures below 10°C, ozone solubility can be more than twice that at high temperatures, resulting in a more significant oxidation effect. Conversely, high temperatures accelerate ozone decomposition, reducing its residence time in water and leading to decreased oxidation efficiency. Therefore, when using ozone powder in summer or in high-temperature regions, the dosage needs to be appropriately increased to compensate for ozone loss.
The pH value of the pool water also has a crucial impact on oxidation efficiency. Ozone decomposes more readily into hydroxyl radicals under acidic conditions. These strong oxidants directly disrupt the molecular structure of chloramine, accelerating the oxidation process. When the pH is neutral or slightly alkaline, ozone's oxidizing ability is somewhat inhibited, potentially slowing the oxidation rate of chloramine. If alkaline substances (such as disinfectant residues) are present in the pool water, the pH must be adjusted to a suitable range to ensure the oxidation efficiency of the ozone powder.
Organic matter content is another important influencing factor. Organic pollutants in the pool water, such as sweat, urine, and skincare products, can combine with chloramine to form more complex compounds, increasing the difficulty of oxidation. When the organic matter concentration is high, the ozone powder needs to consume more energy to decompose these substances, leading to a decrease in the oxidation efficiency of chloramine. Therefore, before using ozone powder, if the pool water is turbid or has a noticeable odor, it is recommended to first reduce the organic matter load through circulation filtration or pre-oxidation treatment to improve the subsequent oxidation effect.
The circulation and mixing state of the pool water directly affects the uniformity of ozone powder distribution. If the circulation system is inefficient, ozone powder may accumulate or settle locally, leading to insufficient oxidation in some areas and excessive oxidation in others. Furthermore, excessively slow water flow prolongs the contact time between ozone and chloramine, but may also reduce efficiency due to excessively rapid ozone decomposition; excessively fast water flow may reduce contact time, affecting the sufficiency of the reaction. Therefore, optimizing the operating parameters of the circulation system (such as flow rate and velocity) is key to improving oxidation efficiency.
Light conditions significantly affect ozone stability. Ultraviolet radiation accelerates ozone decomposition, especially in outdoor pools or environments under direct sunlight, where the ozone half-life may be significantly shortened. If using ozone powder during the day, the attenuating effect of sunlight on ozone concentration must be considered; the dosage should be increased appropriately or treatment should be carried out during periods of shade. For indoor pools, light interference can be reduced by controlling the intensity of lighting or using shade materials.
The coexistence of other chemical substances in the pool water can also affect oxidation efficiency. For example, certain metal ions (such as iron and manganese) may catalyze ozone decomposition or form stable complexes with chloramine, reducing the sensitivity of the oxidation reaction. Furthermore, if a high concentration of residual chlorine already exists in the pool water, ozone powder may preferentially react with the residual chlorine rather than chloramine, leading to a decrease in the oxidation efficiency of the target substance. Therefore, before using ozone powder, the chemical balance of the pool water must be tested to avoid interference from coexisting substances affecting the effect.
User operating habits and maintenance levels are crucial to the long-term stability of oxidation efficiency. Failure to add ozone powder according to the product instructions (such as insufficient or excessive dosage) or failure to regularly clean the circulation system (such as filters and pipes) may cause fluctuations in oxidation efficiency. In addition, the storage conditions of ozone powder (such as humidity and temperature) will also affect its activity; damp or high-temperature environments may reduce product effectiveness. Therefore, strictly following the operating guidelines and maintaining the equipment in good condition are fundamental to ensuring consistently high oxidation efficiency.
