Product Short Description

PAC-01 is a spray-dried white powder polyaluminium chloride developed for low-turbidity surface water. It provides 30% min. Al2O3, 45–55% basicity and 0.1% max. insolubles. The product is supplied in 25kg bags and should be selected through jar tests using the actual low-turbidity lake or reservoir water.

Product Overview

In low-turbidity surface water, the practical objective is to build a strong floc when the water contains too few suspended particles for frequent collisions. PAC-01 is used as a coagulant, not as a complete treatment system.

Its role is to provide charge neutralization while allowing the operator to optimize floc formation with careful dosing and mixing. 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.

Treatment Problem and Causes

The relevant feed is typically low-turbidity lake or reservoir water. The main difficulty is that small colloids, low particle concentration and dissolved organic matter can produce weak pin floc that passes into filters.

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-01 Solution

The recommended role for PAC-01 is to provide charge neutralization while allowing the operator to optimize floc formation with careful dosing and mixing. It is normally applied ahead of a dedicated flocculation and clarification step, with dose control based on low-turbidity jar tests.

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 reservoir intakes, protected surface-water sources and low-solids process-water systems. Operators should follow floc visibility, settled-water turbidity, filter run time and head-loss development.

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

Floc Visibility

Settled-Water Turbidity

Filter Run Time

Head-Loss Development

The key process boundary is clear: overdosing can restabilize particles or increase downstream load, so a fixed dose should not be assumed.

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.

Coagulant Dispersion

Rapid mixing distributes PAC throughout the low-turbidity water before floc growth begins.

Charge Neutralization

Cationic aluminium species reduce the electrical repulsion between negatively charged particles.

Floc Formation

Aluminium hydroxide floc captures fine matter so it can be settled, floated or filtered.

Recommended Application Approach

Characterize the low-turbidity lake or reservoir water, 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: ahead of a dedicated flocculation and clarification step, with dose control based on low-turbidity jar tests.

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 floc visibility, settled-water turbidity, filter run time and head-loss development.

How to Choose the Right PAC Grade

Choose PAC-01 because the narrower basicity range and white appearance support controlled treatment of relatively clean raw water. 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-01 suitable for low-turbidity surface water?

It is a candidate grade because the narrower basicity range and white appearance support controlled treatment of relatively clean raw water. 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 low-turbidity surface water?

Track floc visibility, settled-water turbidity, filter run time and head-loss development. Also verify the limitation that overdosing can restabilize particles or increase downstream load, so a fixed dose should not be assumed.
