Product Short Description

Product Overview

In drinking water treatment, the practical objective is to produce stable clarified water when turbidity and natural organic matter change across the day or season. PAC-01 is used as a coagulant, not as a complete treatment system. Its role is to destabilize colloids and form settleable floc before clarification and filtration.

The grade is positioned for drinking-water and color-sensitive process-water applications, and its spray-dried form dissolves rapidly when the solution is prepared correctly.

Application Scenarios and Control Points

Relevant use cases include municipal plants, private drinking-water systems and packaged clarification units. Operators should follow raw and settled turbidity, floc size, settling rate, filtered-water turbidity and any locally required residual-aluminium control.

These indicators show whether the treatment target is being achieved and whether the dose is creating unnecessary sludge or downstream carryover.

How Polyaluminium Chloride Works

PAC is a pre-hydrolyzed inorganic polymeric coagulant. After dispersion, its cationic aluminium species adsorb on negatively charged particles and reduce the electrical barrier that keeps them apart. As hydrolysis continues, aluminium hydroxide floc provides a sweep-coagulation surface that captures fine particles.

Separation performance therefore depends on product dose, pH, alkalinity, mixing sequence, flocculation time and the selected settling, DAF or filtration equipment.

Recommended Application Approach

How to Choose the Right PAC Grade

Choose PAC-01 because the white, low-insoluble grade is suitable where treated-water appearance and low residue are important. Start with the product specification, but make the final selection on representative water.

Compare at least three doses, include the current coagulant as a control and keep pH, mixing energy and settling time consistent. The TDS gives about 1–15 g/MT for solid PAC as a general reference; the optimum may differ with the water and must be confirmed by laboratory and plant trials.

PAC-01 and PAC-02 are the starting grades for drinking-water and cleaner process-water duties. PAC-01 is white with 45–55% basicity, while PAC-02 is yellow with 45–85% basicity. PAC-031 is the industrial grade with 29% minimum Al2O3, 50–90% basicity and a higher allowable insoluble fraction. Grade selection should reflect treated-water requirements, feed variability and total treatment cost rather than color alone.

Why Work With Bluwat Chemicals

Bluwat Chemicals has manufactured water-treatment chemicals since 2000. The company operates three production bases, exports to more than 80 countries and has served over 5,000 industrial customers. For drinking water treatment, this experience supports grade matching, sample evaluation and communication between the buyer, sales team and technical team before scale-up.

Direct factory support includes batch COA, current TDS and SDS documents, packing checks and traceable quality control for the selected PAC grade. Buyers can compare PAC-01 with other PAC grades using actual water rather than relying only on product color or one headline parameter.

Packaging, Solution Preparation and Storage

Solid PAC is packed in a 25kg inner plastic bag with a polypropylene woven outer bag. Store the sealed original package in a cool, dry place away from heat, flame and direct sunlight.

Prepare a 2–20% solution before dosing, using clean water and sufficient mixing. Do not use wet, contaminated or severely caked material without evaluation.
