The swimming pool is a place of public health, and its quality has a significant impact on the health of tourists. The chlorine tablet dispenser is a widely used chemical disinfection device. Its main function is to slowly dissolve solid chlorine tablets to achieve effective dispersion of chlorine ions in the water, which is of great importance to the water environment in the swimming pool.
Design and Types of Chlorine Tablet Dispenser
Basic Design Principles
Inside the dispenser, there is generally a hydrodynamic mechanism to ensure that water can flow evenly, achieving a slow and uniform dissolution of chlorine. Additionally, most chlorine tablet dispensers are fitted with corresponding regulators, which can be adjusted based on the size of the swimming pool and the required chlorine content.
Overview of Different Types of Chlorine Tablet Dispensers
Floating Chlorine Tablet Dispenser
This dispenser floats directly on the surface, allowing water to flow in through small holes at the bottom, dissolve the chlorine, and then disperse the chlorinated water back into the pool. It is simple to install, easy to transport and position, and suitable for home swimming pools or small-sized pools.
Built-in Chlorine Tablet Dispenser
This dispenser is integrated into the swimming pool’s circulation system to ensure a stable and even release of chlorine tablets. It is appropriate for use in large and public swimming pools.
Automatic Chlorine Tablet Dispenser
This dispenser can be connected to the swimming pool’s pump and filter system, and comes equipped with timing and automatic control devices, which can automatically dispense chlorine tablets according to the set time and frequency.
Comparison of Floating vs. Built-In Chlorine Tablet Dispensers
Installation Method
The floating chlorine tablet dispenser does not require installation and is simple to operate; in contrast, the built-in dispenser necessitates a connection to the swimming pool’s water pipe, making installation more complex.
Applications
Floating dispensers are more suited for small or private swimming pools, whereas built-in dispensers are better for medium to large-sized or commercial pools.
Stability
Built-in dispensers can more stably control chlorine release since they are connected to the circulation system, while floating dispensers can result in uneven chlorine distribution due to wind or water flow.
Maintenance
Floating chlorine tablet dispensers are generally easier to maintain and clean, while built-in dispensers may require professional technical support for regular inspections and maintenance.
Working Principle of Chlorine Tablet Dispenser
The Working Mechanism of the Floating Chlorine Tablet Dispenser
The floating chlorine tablet dispenser uses its own buoyancy to stay afloat. It has small holes on the bottom or sides, allowing water to pass through and come into contact with the chlorine tablets. As water flows, the tablets gradually dissolve, and the dissolved chlorine enters the swimming pool with the flow, providing a sterilizing effect. Users can control the amount of chlorine released by adjusting the openings on the dispenser.
How to Control the Release of Chlorine with a Chlorine Tablet Dispenser
- Adjust the area of chlorine tablets exposed to water: Dispensers generally have adjustable openings. By modifying these, one can control the water flow over the chlorine tablets and thus the amount of chlorine released.
- Use chlorine tablets with different dissolving rates: There are fast-dissolving and slow-dissolving chlorine tablets available. Users can select the type based on their needs.
- Consider the effects of water temperature and pH: Both the temperature and pH of water affect the dissolution rate of chlorine and the efficiency of disinfection. The settings of the dispenser should be adjusted under varying conditions.
Dissolution Process of Chlorine Tablets in the Dispenser
- Step 1 – Contact: Water entering the dispenser comes into contact with the chlorine tablets, starting the dissolution process.
- Step 2 – Dissolution: The tablets begin to slowly dissolve, creating a saturated solution on the surface.
- Step 3 – Diffusion: The dissolved chlorine diffuses into the surrounding water. The saturated water is absorbed, allowing fresh water to contact the chlorine.
- Stage 4 – Circulation: The swimming pool’s circulation system disperses chlorine-infused water throughout the pool and brings untreated water back for sterilization. This cycle ensures the consistent quality of the water.
Throughout this process, the dispenser continuously releases chlorine at a set rate until fully dissolved. Users should regularly check the remaining tablets and replace them as necessary to maintain swimming pool water safety and hygiene.
Thus, the rational selection and utilization of chlorine tablet dispensers play a crucial role in ensuring swimming pool water safety and enhancing the disinfection effect. Based on this, it is recommended to adopt new, intelligent, and environmentally friendly formulations suitable for swimming pool water treatment systems.
