Product Short Description

PAC-02 is a spray-dried yellow powder polyaluminium chloride developed for river-water treatment. It provides 30% min. Al2O3, 45–85% basicity and 0.1% max. insolubles. The product is supplied in 25kg bags and should be selected through jar tests using the actual river water affected by daily and seasonal changes.

Product Overview

In river-water treatment, the practical objective is to manage turbidity, colloidal color and organic-coated particles while keeping downstream filters stable. PAC-02 is used as a coagulant, not as a complete treatment system.

Its role is to provide a controllable coagulation step that can be retuned through regular jar testing. The grade is positioned for drinking-water and general process-water applications, and its spray-dried form dissolves rapidly when the solution is prepared correctly.

Treatment Problem and Causes

The relevant feed is typically river water affected by daily and seasonal changes. The main difficulty is that rainfall, erosion, upstream discharge and biological activity continuously change particle charge and concentration.

As a result, untreated water may show unstable turbidity, weak settling, short filter runs or poor solid-liquid separation. A useful product page must distinguish the removable suspended or colloidal fraction from dissolved contaminants that require other processes.

PAC-02 Solution

The recommended role for PAC-02 is to provide a controllable coagulation step that can be retuned through regular jar testing. It is normally applied between intake screening and flocculation, with optional presedimentation for heavy solids.

When PAC hydrolyzes in water, positively charged aluminium species reduce particle repulsion. Hydroxide floc then enmeshes fine matter and creates aggregates that can be settled, floated or filtered. Effective rapid mixing must distribute the coagulant before slower floc growth begins.

Application Scenarios and Control Points

Relevant use cases include urban river-water plants, industrial river intakes and seasonal surface-water systems.

Urban River-Water Plants

Industrial River Intakes

Seasonal Surface-Water Systems

Operators should follow turbidity, apparent color, pH, alkalinity, settled-water quality and filter run time. These indicators show whether the treatment target is being achieved and whether the dose is creating unnecessary sludge or downstream carryover.

Turbidity

Apparent Color

Alkalinity

Settled-Water Quality

Filter Run Time

The key process boundary is clear: dissolved micropollutants or pathogens require additional treatment barriers.

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.

Intake Screening

Coarse debris is removed and current raw-water conditions are assessed.

PAC-02 Dosing

The dose is adjusted through regular jar testing as river-water quality changes.

Flocculation

Controlled slower mixing supports stable floc growth and solids capture.

Separation and Filtration

Floc is settled, floated or filtered before downstream treatment barriers.

Recommended Application Approach

Characterize the river water affected by daily and seasonal changes, including pH, turbidity or TSS and the contaminants that may remain dissolved.

Prepare the solid PAC as a 2–20% solution with clean water. Allow complete dispersion and keep the solution system clean.

Run a jar test around the TDS reference range of about 1–15 g/MT and reproduce the intended process position: between intake screening and flocculation, with optional presedimentation for heavy solids.

Use rapid mixing for coagulant distribution, then slower mixing for floc growth. Avoid excessive shear after the floc has formed.

Select the lowest stable dose that meets the target while monitoring turbidity, apparent color, pH, alkalinity, settled-water quality and filter run time.

How to Choose the Right PAC Grade

Choose PAC-02 because low insolubles help limit nonfunctional residue in a drinking-water clarification duty. 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 Grade Comparison

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.

Commercial terms, delivery schedule, freight and destination documentation are confirmed by the responsible sales representative.

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.

Frequently Asked Questions

Is PAC-02 suitable for river-water treatment?

It is a candidate grade because low insolubles help limit nonfunctional residue in a drinking-water clarification duty. Suitability must still be verified with the actual water, treatment objective and downstream process.

What PAC dosage should the plant use?

The supplied TDS gives about 1–15 g/MT for solid PAC as a general reference. Start with a dose-response jar test and confirm the result at plant scale; do not copy a dose from another site.

How should the 25kg PAC powder be prepared?

Prepare a 2–20% solution using clean water and adequate mixing. Avoid dumping dry powder directly into a poorly mixed tank, and protect the stored product from moisture.

What should be checked after dosing PAC in river-water treatment?

Track turbidity, apparent color, pH, alkalinity, settled-water quality and filter run time. Also verify the limitation that dissolved micropollutants or pathogens require additional treatment barriers.
