Inquiry now Our core Dichlor-based chlorine granule lineup — engineered for superior algae control in pools, industrial water systems, and beyond.
Dichlor chlorine granules — formally known as Sodium Dichloroisocyanurate (SDIC) — are a fast-dissolving, stabilized chlorine compound widely recognized as one of the most effective solutions for preventing algae growth in swimming pools, water reservoirs, cooling towers, and industrial water systems.
Unlike unstabilized chlorine products, Dichlor granules contain built-in cyanuric acid (CYA), which acts as a UV shield to protect the active chlorine from rapid sunlight degradation. This makes them especially effective for outdoor water bodies where algae proliferation is accelerated by sunlight and warm temperatures.
SDIC granules deliver a consistently high available chlorine level, ensuring rapid algaecidal action even at low dosing concentrations — a critical advantage for large-scale water treatment operations.
The granular form ensures precise dosing, minimal waste, and easy handling — whether for manual application in residential pools or automated dosing systems in municipal and industrial facilities.
Algae growth in water systems is triggered by a combination of sunlight, nutrients, warm temperatures, and insufficient sanitizer levels. Dichlor chlorine granules combat algae through a multi-stage mechanism:
① Rapid Chlorine Release: Upon dissolution, SDIC immediately releases hypochlorous acid (HOCl), the most biologically active form of chlorine, which penetrates algal cell walls and disrupts metabolic processes.
② Sustained Residual Protection: The stabilized formulation ensures a prolonged chlorine residual, maintaining effective concentrations between treatments and preventing re-colonization.
③ Broad-Spectrum Efficacy: Dichlor granules are effective against green algae, blue-green algae (cyanobacteria), mustard algae, and black algae — covering the full spectrum of common aquatic algae species.
Studies show that maintaining a free chlorine level of 1–3 ppm using stabilized Dichlor granules can reduce algae bloom incidents by over 90% compared to untreated water bodies — making it the go-to choice for commercial pool operators globally.
Engineered for performance, safety, and versatility across commercial and industrial applications.
Granular particle size is optimized for rapid dissolution in both warm and cold water, ensuring immediate chlorine availability for instant algae suppression.
Integrated cyanuric acid stabilizer protects chlorine from UV degradation, extending effective residual life by up to 5× compared to unstabilized chlorine in outdoor applications.
SDIC granules have a near-neutral pH profile, minimizing the need for additional pH adjustment chemicals and reducing overall operational costs.
Effective against all major algae species including green, mustard, black, and cyanobacteria — providing comprehensive preventive and curative algae control.
Granular form offers excellent flow properties, precise dosing capability, and extended shelf life under proper storage conditions — ideal for bulk industrial use.
Manufactured to meet international standards including ISO 9001:2015, NSF/ANSI, and EU Biocidal Products Regulation (BPR), ensuring suitability for both recreational and potable water applications.
From residential pools to large-scale industrial systems — Dichlor chlorine granules are the trusted choice across diverse water management environments.
Prevent green water, slippery surfaces, and health hazards caused by algae blooms. Ideal for weekly shocking and routine maintenance dosing.
Cooling tower water is a prime environment for algae and biofilm growth. Dichlor granules control biological fouling, maintaining heat exchange efficiency and system longevity.
Large open reservoirs are vulnerable to cyanobacteria blooms. Controlled dosing of stabilized Dichlor granules provides cost-effective, scalable algae prevention without compromising water quality.
Algae growth in drip irrigation lines causes clogging and crop damage. Dichlor granules maintain clean waterways, protecting irrigation infrastructure and improving water distribution efficiency.
At carefully controlled dosages, Dichlor granules prevent algae overgrowth in aquaculture ponds, maintaining optimal oxygen levels and water clarity for healthier stock.
Decorative ponds, water walls, and spa pools require pristine, algae-free water. Dichlor granules provide reliable, low-maintenance algae prevention for high-visibility water features.
Process water in manufacturing facilities can support algae growth that contaminates products and clogs pipelines. Dichlor treatment ensures clean, compliant process water at all times.
Secondary treatment ponds and clarifiers benefit from Dichlor dosing to control algae blooms that can interfere with treatment efficiency and effluent quality standards.
The global demand for stabilized chlorine-based algae prevention solutions is growing rapidly, driven by expanding water infrastructure, stricter environmental regulations, and increasing awareness of water safety.
The global swimming pool market is projected to exceed USD 5.8 billion by 2030, with Asia-Pacific and Middle East regions driving the fastest growth. This directly fuels demand for high-quality Dichlor chlorine granules as the primary algae prevention chemical of choice for pool operators.
Rapid industrialization in emerging economies is creating massive demand for cooling tower and process water treatment chemicals. Stabilized Dichlor granules are increasingly specified in industrial water treatment contracts due to their superior performance and cost-effectiveness versus liquid chlorine alternatives.
Stricter regulations on chlorine gas handling and liquid sodium hypochlorite storage are accelerating the shift toward solid, stabilized chlorine products. Dichlor granules offer a safer handling profile, lower transport costs, and longer shelf life — aligning perfectly with evolving regulatory requirements in the EU, North America, and Asia.
The integration of IoT-based automated chemical dosing systems in commercial pools and industrial water treatment is creating demand for consistently formulated, free-flowing Dichlor granules compatible with automated dispensers — a trend that rewards high-quality, standardized granule products.
Rising global temperatures and changing precipitation patterns are intensifying algae bloom frequency and severity in both natural and managed water bodies. This climate-driven challenge is significantly expanding the addressable market for preventive algae control chemicals, including Dichlor granules.
Manufacturers are increasingly developing eco-optimized Dichlor formulations with reduced packaging waste, lower carbon footprints, and improved biodegradability profiles — responding to growing buyer demand for sustainable chemical solutions without compromising algae control efficacy.
