How to choose compliance quality polyaluminum chloride manufacturers?
With the improvement of safety and efficiency requirements in the water treatment industry, the production capacity, technical standards and product compliance of Achloride manufacturers have become the core of user attention. This paper, from the national standards, enterprise qualifications, product performance and other dimensions, analyzes the selection strategy of high-quality manufacturers, to help users accurately match the needs.
- Core certification and standards of compliance manufacturers
- National standard and requirements
-Drinking water grade PAC: GB / T 15892-2020,29% alumina content, heavy metal (arsenic, lead, etc.) trace grade limit.
-Industrial grade PAC: GB / T 22627-2022, liquid product alumina content 6.0%, water insoluble content 0.4%.
-The Compliance manufacturer shall provide the third-party test report and mark the national standard number applicable to the product.
- Enterprise qualification and production specifications
According to the "Product Quality Law", high-quality manufacturers should have ISO certification, environmental protection production license, and establish a sound quality management system. It is recommended to choose the national high-tech enterprise certification manufacturers.
- Select the five key indicators of the manufacturers
- Product performance matching degree
-Select the alumina content (28% -32%) and the salinity base (45% -50%) according to the water quality type (high turbidity, low pH, etc.).
-Industrial wastewater treatment should pay attention to the COD removal rate, and the drinking water field should focus on heavy metal residue data.
- Production scale and supply capacity
Large manufacturers (such as Henan Ran) usually have 10,000 tons to ensure stable supply; SMEs may be more flexible and suitable for small batch customization.
- Research and development and technological innovation
Priority to choose enterprises with patented technologies (such as efficient fluoride removal process) or participating in the formulation of national standards.
- After-sales service system
Including technical guidance, emergency response, long-term water quality monitoring, etc., to reduce user operation risks.
- Cost performance and transportation cost
The transportation radius of liquid PAC is recommended to be 500 kilometers, and solid products can be covered nationwide, requiring comprehensive unit price and logistics costs.
- Industry application scenarios and manufacturer adaptation suggestions
-Water plant: select drinking water grade PAC head manufacturers (such as Songyang water purification) to ensure compliance with the GB 5749-2022 drinking water sanitation standards.
-Sewage treatment in industrial park: industrial suppliers such as Shenzhen Hongsen are recommended for high COD and heavy metal wastewater treatment.
-Rural safe drinking water project: small and medium-sized manufacturers have higher cost performance, need to provide simple operation plan and training support.
- Future trends: green production and digital services
- Environmental protection process upgrade
Acid dissolution method or spray drying technology without waste residue discharge is used to reduce production pollution.
- Digital solutions
Some manufacturers (such as Henan calm) launched the Internet of Things monitoring system to track water quality and drug injection effect in real time.
- Globalization
Head enterprises to expand overseas markets, through the international certification (such as NSF, REACH) to enhance the competitiveness.
