Super Impact SWIMDonozone powder, as a highly efficient water treatment product, directly impacts its reaction efficiency and effectiveness in water bodies through its dissolution rate. The dissolution process is essentially the interaction, dispersion, and formation of a homogeneous system between the solid powder and water molecules, a process dynamically regulated by multiple factors.
Water temperature is one of the core factors affecting the dissolution rate of ozone powder. According to molecular dynamics principles, increased temperature accelerates the thermal motion of water molecules, significantly increasing the frequency and energy of collisions with ozone powder particles. For example, at 25°C, the kinetic energy of water molecules is sufficient to quickly overcome the lattice energy of the ozone powder particle surface, causing particle disintegration; however, when the water temperature drops to 10°C, molecular motion slows down, potentially prolonging the dissolution process several times over. Furthermore, water temperature indirectly affects the release rate of active oxygen components in the ozone powder; at high temperatures, active oxygen is more easily released from the solid matrix and enters the aqueous phase to participate in oxidation reactions.
The pH value of the water body also plays a crucial role in regulating the dissolution of ozone powder. The active components in ozone powder exhibit different dissociation states in acidic or alkaline environments. Under weakly acidic conditions, some components may exist in molecular form with low solubility. However, when the pH rises to neutral or weakly alkaline, these components are more easily converted into ionic states, significantly increasing the dissolution rate. For example, chloramines are more easily oxidized to nitrogen gas by ozone in an alkaline environment, a process that requires the ozone powder to be fully dissolved. If the pH of the water deviates from the suitable range, it will not only reduce the dissolution rate but may also affect the pathway and efficiency of subsequent oxidation reactions.
The intensity of stirring significantly affects the dissolution of ozone powder by altering the water flow field distribution. In static water, ozone powder particles mainly dissolve gradually through diffusion, with the dissolution front exhibiting a spherical progression and low efficiency. Introducing mechanical stirring or a circulating pump creates turbulent flow, disrupting the boundary layer on the particle surface and continuously replenishing the dissolution interface with fresh water molecules, accelerating mass transfer. Experiments show that moderate-intensity stirring (e.g., 100-200 rpm) can shorten the dissolution time by 30%-50%, but excessive stirring may cause powder splashing or agglomeration, thus reducing efficiency.
The particle size distribution of ozone powder directly determines its specific surface area, thus affecting dissolution kinetics. Smaller particle sizes result in a larger total surface area per unit mass of powder, increasing the contact area with water molecules and leading to a faster dissolution rate. For example, refining ozone powder particles from 100 mesh to 200 mesh can nearly double the dissolution rate. However, excessive grinding can increase the powder's hygroscopicity, making it prone to clumping during storage, which is detrimental to on-site application and rapid dissolution. Therefore, a balance must be struck between particle size control and storage stability in practical applications.
The effects of substances coexisting in water on ozone powder dissolution are dual. On one hand, hardness ions such as calcium and magnesium may adsorb or complex onto the powder surface, forming a barrier layer that slows dissolution. On the other hand, certain organic compounds (such as humic acid) may act as surfactants, reducing the interfacial tension between particles and water, promoting wetting and dispersion. For example, in water bodies containing high concentrations of organic pollutants, the initial dissolution rate of ozone powder may be increased due to the auxiliary effect of organic matter, but in the long term, the consumption of reactive oxygen species by organic matter may indirectly affect the overall oxidation efficiency.
The method of addition and operational procedures are crucial for controlling the dissolution rate. Directly pouring ozone powder onto the water surface may result in excessively high local concentrations, causing particle agglomeration and clumping, hindering dissolution. However, using methods such as multi-stage addition or pre-mixing in a dissolution tank ensures uniform powder dispersion and improves dissolution efficiency. Furthermore, the choice of addition location must consider water flow distribution to avoid powder deposition in stagnant water areas. For example, in a swimming pool circulation system, adding ozone powder near the return water inlet utilizes the impact of the water flow to accelerate dissolution and mixing.
The dissolution rate of Super Impact SWIMdonozone powder is the result of the synergistic effect of multiple factors, including water temperature, pH value, stirring intensity, particle size distribution, coexisting substances, and addition method. In practical applications, these parameters must be comprehensively adjusted according to specific water quality conditions and treatment objectives to achieve efficient dissolution and rapid reaction of the ozone powder, thereby fully realizing its core functions such as eliminating chlorine odor, oxidizing organic matter, and inhibiting algae.
