Polyaluminum chloride is a commonly used water treatment agent for purifying water sources, especially for treating industrial wastewater and urban sewage. When purchasing polyaluminum chloride, it is usually necessary to pay attention to the following indicators:
Aluminum content: Aluminum content is one of the main components of polyaluminum chloride, which has a significant impact on its performance. When purchasing, it is necessary to ensure that the aluminum content of the product meets the specified standards to ensure the effectiveness of water treatment.
Coagulation performance: Polyaluminum chloride is mainly used for coagulation and precipitation of suspended solids, improving the sedimentation rate of impurities in water. The quality of coagulation performance directly affects the effectiveness of water treatment, so it is necessary to pay attention to the coagulation performance indicators of the product.
Solubility: The solubility of polyaluminum chloride affects its dissolution rate in water, and either too fast or too slow may affect the effectiveness of water treatment. The solubility of the product needs to comply with relevant standards.
PH value: The use of polyaluminum chloride usually involves adjusting the pH value of water, so the pH value of the product also needs to be considered.
Color and appearance: The color and appearance of a product are also important indicators for measuring its quality, and transparency and color uniformity are directly related to the purity of the product.
Cost effectiveness: In addition to product quality, it is also necessary to consider the cost-effectiveness of procurement. Compare the prices, packaging, transportation, and other factors of different suppliers to find products with suitable cost-effectiveness.
Supplier Reputation: Choose suppliers with good reputation and reliable supply records to ensure product stability and reliability.
Environmental factors: Consider the environmental performance of the product to ensure compliance with relevant environmental regulations and standards.
When purchasing polyaluminum chloride, it is very important to select suitable products based on specific water treatment needs and comprehensive consideration of the above indicators.
