Swimming pool water quality is an important public health issue. The quality of pool water greatly affects swimmers’ health. Microbial contamination, chemical contamination and algae proliferation are the main causes of these problems. To combat algae blooms, swimming pools need to use pool algaecide. These cleaners effectively kill pool algae and prevent its overgrowth. Through this article, we hope to provide readers with a deeper understanding of swimming pool water quality and effective treatment methods.
ⅠTypes of Pool Algal Cleaners
Chemical Cleaners
Chlorine-based Cleaners
These are common pool cleaning agents that kill and inhibit bacteria and algae in the water. Commonly used are trichlor disinfectants, dichlor disinfectants, calcium hypochlorite disinfectants, and sodium hypochlorite disinfectants.
Non-chlorine Cleaners
These cleaners primarily chelate copper ions, a method used by most swimming facilities. Copper ions, being heavy metal ions, can bind faster than magnesium ions, sodium ions, etc., in algal chlorophyll synthesis, causing chloroplast metal poisoning, inhibiting photosynthesis, leading to algal death.
Biological Cleaners
Biological cleaners use biotechnology to treat wastewater and algae. For instance, the bacteria-algae symbiotic biofilm wastewater treatment technique leverages the synergistic mechanism of bacteria and microalgae, strong tolerance of algae, and efficient biomass resource utilization, achieving effective pollutant removal and microalgal biomass harvest simultaneously.
Physical Cleaning Methods
Physical cleaning primarily involves brushing the pool surface, especially corners with moss growth. Additionally, ultrasonic algae removal equipment can be employed. This equipment can rival high-fidelity stereo systems, producing high-precision acoustic click signals.
Ⅱ.Considerations in Choosing a Cleaner
Water Quality Testing and Analysis
It’s essential to consider water quality when selecting a cleaner. Factors to consider include the type of contaminants, chelating agents required, and other additives.
Effectiveness and Cost of the Cleaner
It’s also important to consider the effectiveness and cost of the cleaner. Ensure you choose products with chemical safety certifications to minimize harm. Quality cleaners can slow down subsequent contamination, reducing the cleaning burden.
Ⅲ.Proper Application of the pool algaecide
Concentration and Application Method
Pay attention to the amount and application method of the cleaner. For automated cleaning processes, determine the concentration of strong alkali or weak acid cleaners, with conductivity measurement being the most straightforward method. Cleaners can also be concentrated and diluted for cleaning. If the concentration is too low, it becomes ineffective; if too high, it’s hard to remove residues, requiring frequent cleaning.
Cleaning Schedule
When using a cleaner, also note its application schedule. For example, in a closed, unoccupied space, use ozone at a concentration of 20mg/m3 for 30 minutes.
Safety Precautions with Cleaners
Be cautious when using cleaning agents. Don’t mix different cleaners, which could cause toxic gas or explosions. Wear masks, goggles, and gloves during dilution or repackaging to avoid contamination. If exposed, rinse immediately with plenty of water.
Pool algaecides clean pool water, prevent algal growth, improve water quality, and protect the environment. Whether chlorine-based or non-chlorine chemical cleaners, biological or physical cleaning, each has its unique purpose. Rational and effective application can inhibit and kill water algae, ensuring cleaner and clearer pool water.
