Product Short Description

PAC-01 is a spray-dried white powder polyaluminium chloride developed for groundwater pretreatment. 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 groundwater containing turbidity or oxidized iron and manganese particles.

Product Overview

In groundwater pretreatment, the practical objective is to remove fine mineral solids before filters, membranes or disinfection while avoiding the claim that coagulation removes every dissolved species. PAC-01 is used as a coagulant, not as a complete treatment system.

Its role is to capture suspended mineral and previously oxidized metal hydroxide particles in a larger floc. 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 groundwater containing turbidity or oxidized iron and manganese particles. The main difficulty is that well disturbance, aquifer fines and oxidation of dissolved iron or manganese can create particles that remain suspended.

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 capture suspended mineral and previously oxidized metal hydroxide particles in a larger floc. It is normally applied after aeration or oxidation where dissolved iron or manganese must first be converted, and before clarification or filtration.

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 well-water plants, industrial borehole-water systems and pretreatment before media filtration.

Well-Water Treatment Plants

Industrial Borehole-Water Systems

Pretreatment Before Media Filtration

Operators should follow turbidity, oxidized iron or manganese, filter pressure loss and sludge production. These indicators show whether the treatment target is being achieved and whether the dose is creating unnecessary sludge or downstream carryover.

Turbidity

Oxidized Iron or Manganese

Filter Pressure Loss

Sludge Production

The key process boundary is clear: PAC is not a substitute for oxidation when metals remain dissolved.

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.

Aeration or Oxidation

Dissolved iron or manganese must first be converted into removable particles where required.

PAC Coagulation

PAC destabilizes and captures suspended minerals and oxidized metal hydroxide particles.

Clarification or Filtration

The resulting floc is separated before the downstream treatment stage.

Recommended Application Approach

Characterize the groundwater containing turbidity or oxidized iron and manganese particles, 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: after aeration or oxidation where dissolved iron or manganese must first be converted, and before clarification or filtration.

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, oxidized iron or manganese, filter pressure loss and sludge production.

How to Choose the Right PAC Grade

Choose PAC-01 because the low-insoluble white grade is appropriate for polished raw-water pretreatment. 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.

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 groundwater pretreatment?

It is a candidate grade because the low-insoluble white grade is appropriate for polished raw-water pretreatment. 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 groundwater pretreatment?

Track turbidity, oxidized iron or manganese, filter pressure loss and sludge production. Also verify the limitation that PAC is not a substitute for oxidation when metals remain dissolved.
