Pools and Water Parks — The Technological Evolution from "Water Quality Compliance" to a "Sensory Feast"

In this high-traffic, high-revisit entertainment water environment, our product solution is designed to address three core challenges: sensory irritation (red eyes/odors), water clarity (cloudiness/whitening), and equipment operational stability (foaming/clogging).

1. Disinfectant: Eliminating the misconception of "chlorine smell" and achieving odorless sterilization

Technical Insight: The public often mistakenly assumes that "strong chlorine smell means effective disinfection." In reality, that pungent "pool odor" is chloramine (combined chlorine)—a byproduct formed when free residual chlorine reacts with organic nitrogen compounds in sweat and urine. Chloramine is significantly more irritating than free chlorine and has very limited germ-killing ability.

Our technical solution:

Breakpoint Chlorination: We recommend using a high dose of trichloroisocyanuric acid (TCCA) for shock chlorination after closing. Its oxidation potential (E° ≈ 1.36 V) is sufficient to oxidize the nitrogen in chloramines into harmless nitrogen gas (N₂), effectively eliminating the chloramine taste at the chemical level.

Cyanuric Acid (CYA) Intelligent Control: For outdoor pools, our TCCA tablets are formulated with an optimal amount of cyanuric acid (stabilizer). By forming a weak "chlorine-cyanuric acid" complex, it slows down the photolysis rate of free chlorine under intense ultraviolet (UV) light—extending its half-life from less than 2 hours to over 6 hours and thereby prolonging effectiveness.

Non-chlorine auxiliary disinfection: For indoor or temperature-controlled pools, we provide potassium monopersulfate (KMPS) as a shock agent. It does not produce chloramines and can rapidly oxidize organic contaminants without increasing free chlorine levels, achieving "clear water" disinfection and significantly reducing skin dryness and eye irritation after swimming.

2. Coagulant: Creating visually stunning, crystal-clear water with captivating clarity

Technical Insight: Pool water turning white or cloudy is often not due to large debris, but rather suspended colloids (particle size less than 1 μm) and inactivated microbial residues. These tiny particles carry the same negative charge, repel each other, and cannot be trapped by quartz sand filters.

Our technical solution:

Efficient PAC adsorption and bridging: Our specialized polyaluminum chloride (PAC) contains a high concentration of Al₂O₃ (≥30%), which rapidly hydrolyzes upon contact with water to form multinuclear hydroxyl complexes. These complexes compress the double layer of colloids through electrostatic neutralization (reducing zeta potential close to 0), thereby destabilizing the particles.

Ultrafine flocculation: Combined with high-molecular coagulant aid (PAM), it rapidly forms flocs with a settling velocity of 5–10 m/h. We recommend adding the flocculant to the pipeline at the front end of the circulation filter, allowing un-settled micro-flocs to be directly intercepted by the filter rather than settling to the bottom for suction. This approach not only reduces sludge accumulation at the bottom but also enables "dynamic clarification" during operation, ensuring uninterrupted visitor experience.

Water quality indicator: With this treatment method, the pool water turbidity can rapidly decrease from an initial level of 5–10 NTU to below 0.5 NTU, meeting the International Swimming Federation (FINA)'s "extreme clarity" standard for competitive swimming water quality.
