Access to safe, clean drinking water is a fundamental human need. The purification process in municipal water treatment plants relies on various chemical agents, among which Polyaluminum Chloride (PAC) plays a vital role. As a leading chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-purity, drinking water grade PAC that meets stringent safety and efficacy standards. This article explores why choosing the right PAC is essential for public health and where to source reliable products.

The Importance of PAC in Drinking Water Purification

Drinking Water Grade PAC is a highly efficient coagulant used to remove impurities such as turbidity, suspended solids, organic matter, and color from raw water sources like rivers, lakes, and reservoirs. Its effectiveness lies in its ability to destabilize and aggregate these particles, making them easier to remove through sedimentation and filtration processes. Unlike some other coagulants, PAC is known for its broad effective pH range and its minimal impact on the alkalinity of the treated water, which translates to cost savings on additional chemicals and reduced sludge production.

When considering the purchase of PAC for drinking water applications, purity is paramount. Regulatory bodies worldwide set strict limits on the presence of heavy metals like arsenic, lead, cadmium, mercury, and chromium. Drinking Water Grade PAC must be produced under rigorous quality control measures to ensure it complies with these health standards. For this reason, NSF (National Sanitation Foundation) certification is often a key indicator of a product's suitability for potable water treatment.

Specifications for Drinking Water Grade PAC

When you search for 'drinking water treatment chemical manufacturer' or 'buy PAC for potable water,' it's crucial to scrutinize the product specifications. Key parameters to consider include:

  • Aluminum Oxide (Al2O3) Content: Typically higher in drinking water grades to ensure maximum treatment efficiency.
  • Basicity: Optimized for effective coagulation in potable water treatment.
  • Heavy Metal Limits: Extremely low levels of contaminants like arsenic (As), lead (Pb), cadmium (Cd), mercury (Hg), and chromium (Cr) are mandatory. For instance, for CAS 1327-41-9, very low levels of these are specified for drinking water grade.
  • Water Insoluble Matter: A minimal percentage ensures the product is highly pure.
  • pH: While generally acidic, the specific pH range for a 1% solution is an important indicator.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying drinking water grade PAC that adheres to these strict quality parameters. As a reputable manufacturer in China, we ensure our products are safe, effective, and competitively priced.
