When tasked with sourcing effective water treatment chemicals, understanding the nuances of Polyaluminium Chloride (PAC) is paramount. As a versatile inorganic polymer flocculant, PAC plays a critical role in purifying both potable water and industrial wastewater. For procurement managers and R&D scientists, selecting the correct PAC variant can significantly impact treatment efficiency, cost-effectiveness, and environmental compliance. This guide aims to demystify the process of choosing the right PAC, ensuring you make an informed purchase from a reputable Polyaluminium Chloride manufacturer.

The effectiveness of PAC stems from its ability to neutralize the negative charges on suspended particles in water, causing them to aggregate into larger flocs that can be easily removed through sedimentation or filtration. However, not all PAC products are created equal. Key differentiating factors include basicity, Al2O3 content, and purity (water insolubles).

Understanding Key PAC Specifications:

1. Basicity: This refers to the degree of neutralization of the aluminum chloride. A higher basicity generally indicates a higher degree of polymerization and a greater charge density, leading to more efficient coagulation. For instance, PAC with basicity ranging from 40% to 90% is commonly available, with higher basicity often preferred for challenging water conditions.

2. Al2O3 Content: This represents the amount of aluminum oxide in the product. Higher Al2O3 content typically means a more concentrated product, allowing for lower dosage rates and better cost efficiency. Common grades range from 28% to 31% Al2O3.

3. Water Insolubles: This is a critical indicator of product purity. Lower water insolubles mean a purer product, which translates to less sludge formation and improved treatment outcomes. For drinking water applications, very low water insolubles (e.g., ≤ 0.1%) are essential. Industrial grades might tolerate slightly higher levels (e.g., ≤ 1.5%).

Selecting PAC for Specific Applications:

For drinking water purification, it is imperative to select PAC grades that are certified for potable water use, typically those with high purity and low water insolubles. The 'Drinking Water Grade' PAC offered by many suppliers ensures compliance with stringent health and safety standards.

In industrial wastewater treatment, the choice of PAC may depend on the specific contaminants and their concentrations. For instance, textile wastewater, which often contains dyes and high organic loads, might require different PAC formulations than general industrial effluent. Consulting with a reliable Polyaluminium Chloride supplier for product recommendations based on jar tests is highly advisable.
