Explore our premium range of SDIC and chlorine formulations engineered to meet international safety and efficacy standards for industrial, commercial, and residential applications.
Hanoi, the rapid-growing capital of Vietnam, stands as a major economic and industrial hub in Southeast Asia. With rapid urbanization, a booming manufacturing sector, and a dense population, the city faces critical demands for advanced water treatment and public sanitization solutions. Sodium Dichloroisocyanurate (SDIC) tablets have emerged as a vital tool in Hanoi’s hygiene and water purification strategies.
The tropical monsoon climate of northern Vietnam, characterized by hot, humid summers and frequent heavy rainfall, creates ideal conditions for waterborne pathogens and agricultural diseases. From municipal water plants upgrading their chlorination systems to local aquaculture farms in the Red River Delta aiming for biosecurity, the requirement for stable, high-active chlorine sources is continuous. SDIC tablets, known for their rapid dissolution, high stability, and ease of dosage, offer the perfect alternative to unstable liquid chlorine bleach and hazardous chlorine gas.
As a leading OEM SDIC Tablets Manufacturer and Exporter, we specialize in supplying customized chemical formulations that meet the specific environmental regulations and industrial standards of Vietnam. Our supply chain network ensures that distributors, industrial plants, and municipal authorities in Hanoi receive prompt shipments of top-tier disinfection tablets.
Founded in 2015, Hebei Liuhe Chemicals Co., Ltd. has grown into a premier manufacturer of water treatment chemicals. The site is close to National Highway 339, only 65 km from the provincial capital and 10 km from the Ningjin exit of the Qingdao–Yinchuan Expressway, offering convenient transportation and an excellent geographical location for fast-track shipping to international ports serving the Hanoi market.
Our state-of-the-art facility spans over a vast area, utilizing automated production lines and precision laboratories to maintain the highest quality standards. We specialize in OEM and ODM services, enabling us to customize tablet sizes, dissolution rates, and packaging to meet the specific requirements of our Vietnamese clients.
Our SDIC tablets are engineered to perform efficiently in tropical environments, providing reliable sanitation across various local sectors in Hanoi and surrounding northern provinces.
In the Red River Delta and coastal areas near Hanoi, aquaculture is a primary economic driver. Maintaining water quality is crucial to prevent outbreaks of White Spot Syndrome Virus (WSSV) and Early Mortality Syndrome (EMS) in shrimp ponds. Our SDIC tablets dissolve rapidly to release active hypochlorous acid, sanitizing the water column without leaving harmful residues or altering the pH drastically, ensuring a healthy environment for aquatic life.
Hanoi’s industrial zones, such as Thang Long Industrial Park and Quang Minh Industrial Park, house massive textile, electronics, and food processing facilities. SDIC is widely used for industrial recirculating cooling water treatment to prevent biofouling, algae growth, and slime accumulation. In textile manufacturing, it serves as a highly controllable bleaching agent that minimizes fabric damage compared to traditional calcium hypochlorite.
As Hanoi's tourism sector thrives, high-end hotels, resorts, and public water parks require superior pool sanitation. Our multifunctional chlorine tablets and SDIC tablets provide long-lasting disinfection under intense tropical sunlight. By stabilizing the chlorine against UV degradation, these tablets keep Hanoi's recreational waters crystal clear and safe for thousands of daily visitors.
During the rainy season, Hanoi is prone to localized flooding, which can contaminate local wells and municipal water supplies. SDIC effervescent tablets are highly valued by humanitarian organizations and municipal authorities for rapid water purification. A single tablet can render contaminated water safe for drinking, washing, and sanitizing, preventing outbreaks of cholera, typhoid, and other waterborne diseases.
Hanoi's healthcare facilities and commercial centers require strict biosecurity protocols. SDIC tablets are the gold standard for preparing disinfectant solutions used to mop floors, sanitize medical equipment, and sterilize surface contact areas. They are highly effective against a broad spectrum of pathogens, including bacteria, viruses, fungi, and spores, providing peace of mind for public health management.
