In pool operation and maintenance, efficient and safe cleaning chemicals are the core to ensuring water quality and the health of swimmers. Trichloroisocyanuric acid (TCCA) and sodium dichloroisocyanurate (SDIC) have become the mainstream choices for global pool water treatment due to their excellent bactericidal and disinfection properties. This article will analyze the advantages and applications of these two products, and preview the participation of Jinmai (JINMAI) in the 2026 Asia Pool & Spa Expo.
TCCA is a high-efficiency and broad-spectrum chlorinated isocyanuric acid disinfectant with an available chlorine content exceeding 85%. It can quickly kill bacteria, viruses, algae and other microorganisms, while inhibiting algae growth. Its core advantages are:
· Slow-release and long-lasting: Releases available chlorine slowly in water, maintaining long-term disinfection effect and reducing the cost of frequent dosing.
· Strong stability: Resistant to light and high temperature, safer for storage and transportation, suitable for large-scale scenarios such as public pools and water parks.
· Wide application: Can be used for daily disinfection and shock treatment, covering various pool and SPA water environments.
SDIC has an available chlorine content of 55%-60%, dissolves quickly, and can rapidly increase residual chlorine concentration, making it suitable for emergency disinfection. Its core advantages are:
· Rapid dissolution: Dissolves quickly in water without residue, and will not clog pool filtration systems.
· pH-friendly: Has minimal impact on water pH fluctuations, reducing the need for pH adjustment operations.
· Easy to use: Can be made into granules, tablets or powder, suitable for family pools and small SPA scenarios.
The use of TCCA and SDIC must follow scientific specifications to ensure water quality safety:
1. Accurate dosing: Calculate the dosage based on pool volume, water temperature, passenger flow and residual chlorine data to avoid skin irritation caused by excessive dosage or disinfection failure due to insufficient dosage.
2. Combined optimization: Use SDIC for quick chlorine supplementation in daily maintenance, and TCCA for long-term disinfection regularly. Combine with pH adjusters to maintain water quality within the standard range (pH 7.2-7.8, residual chlorine 0.3-0.5mg/L).
3. Safe operation: Wear protective equipment to avoid direct contact, store in a dry, cool and ventilated place, away from fire sources and reducing agents.
Jinmai (JINMAI) is a professional enterprise engaged in the R&D and production of water treatment chemicals. With advanced technology, strict quality control and a complete service system, it has become a globally trusted supplier of TCCA and SDIC. The products meet international safety standards, and can provide customized packaging and technical support to help customers achieve efficient pool water quality management.
From May 15 to 17, 2026, Jinmai will bring its core pool cleaning chemicals to the 2026 Asia Pool & Spa Expo (Grandeur. Asia Pool & Spa Expo) held at the China Import & Export Fair Complex in Guangzhou. During the exhibition, we will showcase our latest TCCA/SDIC products, intelligent dosing solutions and water quality optimization technologies, to communicate and cooperate with global industry partners and explore new development opportunities for the pool and SPA industry.
With their performance advantages, TCCA and SDIC have become the core disinfection choices for pool operators. Jinmai (JINMAI) has always been committed to providing efficient and safe water treatment solutions. We look forward to meeting you at the 2026 Asia Pool & Spa Expo, working together to create win-win cooperation and promote high-quality development of the industry.
