Clorazione della piscina

Since the 1970’s, we have offered solutions for swimming pool chlorination. Our coating solutions in saltwater pool chlorination have evolved from static polarity to our state-of-the-art self-cleaning technology.

Bid farewell to the discomfort of chlorine odor, irritated eyes, hair damage, and faded swimsuits, all stemming from excessive disinfection by-products and over-chlorination. Harnessing the power of common salt and electricity, our innovative approach consistently delivers the perfect amount of pure chlorine solution, ensuring a safe, simple, and cost-effective pool disinfection process.

At our core, we are dedicated to enhancing your recreational water quality while adhering to environmentally conscious practices.

The Benefits of Salt Chlorination are Multifold:

Experience the luxury of silky-smooth pool water, elevating your swimming enjoyment to unparalleled heights.
Ensures a steady generation of chlorine solution, effectively thwarting chlorine spikes and algae outbreaks.
Say goodbye to the hassles of chemical storage and handling, as this solution minimizes these requirements.
With an average lifespan of 3-5 years for our chlorinators, you'll find yourself making fewer trips to the pool store, as the chlorine is conveniently produced on-site.

Unlocking the Chemistry Behind Salt Chlorination

Understanding the technical intricacies of salt chlorination is essential for maximizing its efficiency and efficacy in pool water treatment:

Activation Process: Upon energizing the salt chlorinator, electrodes initiate catalytic reactions with sodium chloride and water molecules at the anode and cathode surfaces, culminating in the generation of chlorine solution.
Chlorine Forms: The resulting chlorine exists primarily as hypochlorous acid and sodium hypochlorite within the pool water, with the proportion of each dependent on the water's pH level.
Recycling Mechanism: As the chlorine disinfectant fulfills its role by neutralizing pathogens and oxidizing organics/contaminants, it undergoes a cyclic transformation, reverting to its native state as salt (NaCl) dissolved in water.

Overall Chemistry Reaction:

NaCl + H2O + electricity --> NaOCl (disinfectant)

Primary Anode Reaction: 2 Cl- - 2 e- ⇒ Cl₂

Primary Cathode Reaction: 2H₂O + 2 e- ⇒ H₂ + 2 OH-

By utilizing these underlying chemical processes, pool owners and operators can effectively harness the power of salt chlorination to maintain pristine water quality, ensuring a safe and enjoyable swimming experience for all.

At the core of our salt chlorination solution is a steadfast commitment to Environmental, Social, and Governance (ESG) principles. By harnessing salt and electricity to generate chlorine solution onsite, we minimize chemical transportation, storage, and carbon emissions, exemplifying our environmental responsibility. This approach not only enhances water quality but also fosters a safer and more enjoyable swimming environment, prioritizing the well-being of pool users and promoting social impact. Upholding the highest standards of governance, transparency, and accountability, we continuously strive for excellence in product development and regulatory compliance, ensuring trust and confidence from our customers and stakeholders. Through the integration of ESG principles, we aim to create a positive and sustainable impact on the environment, society, and governance landscape within the water treatment industry.
