China Industrial Grade Polyaluminium Chloride Manufacturers, Suppliers and Factory

Product Overview

Industrial Grade Polyaluminium Chloride (PAC) is a water-soluble inorganic polymer bridging agent engineered for rapid coagulation and flocculation in aqueous systems. Compared to traditional coagulants like alum (aluminum sulfate), PAC operates effectively across a broader pH range (5.0 to 9.0) and leaves lower residual aluminum concentrations in treated effluents.

Our industrial-grade formulation is manufactured via optimized spray-drying or drum-drying processes, yielding a uniform granular powder or clear liquid with high active aluminum content. It functions by neutralizing negative charges on suspended colloidal particles, forming dense, fast-settling aluminum hydroxide flocs that trap turbidity, color, organic matter, and heavy metals.

Key Features

Wide Operating pH Range:

Maintains coagulation efficiency across pH 5.0 to 9.0, reducing the need for secondary pH adjustment chemicals.

Rapid Flocculation Kinetics:

Pre-polymerized aluminum species shorten the initial hydrolysis phase, accelerating micro-floc formation and settling velocity.

Low Sludge Generation:

Produces 30% to 50% less sludge volume compared to aluminum sulfate or ferric chloride, lowering sludge dewatering and disposal costs.

Low Temperature Performance:

Retains effective coagulation performance in cold water conditions (< 5°C) where traditional aluminum sulfate activity drops significantly.

Reduced Residual Aluminum:

Leaves lower soluble aluminum residual in treated water, preventing downstream scaling and equipment corrosion.

Applications

PRIMARY INDUSTRIAL APPLICATIONS:

Municipal Water Treatment: Drinking water clarification, turbidity, and natural organic matter (NOM) removal.

Industrial Wastewater: Effluent treatment for textile dyeing, paper mills, petrochemical plants, and electroplating rinse water.

Sludge Conditioning: Municipal and industrial sludge dewatering prior to filter press or centrifuge.

Paper Industry: Internal sizing agent and drainage aid in neutral/alkaline papermaking processes.

Product Selection Guide

Selecting the correct PAC variant depends on raw water turbidity, temperature, and specific contaminant profiles. Review the selection matrix below:

Application Parameter	Recommended Solid PAC Variant	Operational Rationale
High Turbidity Surface Water (> 100 NTU)	PAC 30% (Medium/High Basicity)	Higher charge neutralization capacity rapidly aggregates heavy suspended silt.
Cold Water Treatment (< 5°C)	PAC 30% Spray Dried	Pre-hydrolyzed polymer structure bypasses slow low-temperature hydrolysis kinetics.
Industrial Heavy Metal Effluent	PAC 28% Low Iron	Minimizes secondary iron interference while precipitating heavy metal hydroxides at optimized pH.
Wastewater Phosphorus Removal	PAC Liquid (10% to 17%)	Direct liquid dosing integrates easily into automatic chemical feed skids for phosphate binding.

Manufacturing & Quality Control

Our production facility operates continuous reaction vessels paired with automated spray-drying towers, regulated by a distributed control system (DCS) to maintain strict reaction stoichiometry.

01/

Raw Material Verification: Bauxite and hydrochloric acid inputs undergo incoming assay testing for heavy metal limits before reactor charging.

02/

In-Process Monitoring: Reaction temperature, pressure, and basicity are sampled every 30 minutes via automated titration loops.

03/

Batch Traceability: Every production lot is assigned a unique batch number linked to an archived analytical Certificate of Analysis (COA) detailing exact Al2O3, basicity, and insoluble particle metrics.

04/

Laboratory Testing Equipment: Finished lots are verified using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for heavy metal speciation and laser particle sizing for dissolution properties.

Frequently Asked Questions

Q: What is the shelf life of solid PAC powder, and how does humidity affect storage?

A: Solid PAC powder has a shelf life of 24 months when stored in unopened, moisture-proof packaging. Because PAC is hygroscopic, exposure to ambient humidity causes surface caking. Store pallets on raised dunnage away from concrete walls, ensure indoor warehouse humidity is kept below 70%, and reseal opened bags immediately.

Q: How do I calculate the correct dosing rate for industrial wastewater treatment?

A: Initial dosing rates typically range from 5 to 50 mg/L depending on raw water turbidity and organic load. Jar testing is required to determine the precise optimal dosage. Calculate dry powder solution preparation by dissolving 10g of solid PAC in 990g of clean water (1% stock solution) for bench-scale trial injection.

Q: Can solid PAC powder be dissolved directly in the main treatment basin?

A: No. Solid PAC must be pre-dissolved in a dedicated mixing tank equipped with a mechanical agitator to a concentration of 5% to 10% before feeding into the system. Direct dumping of powder into basins causes incomplete dissolution, localized high viscosity, and clogging of chemical feed pumps.

Q: What are the differences in performance between drum-dried and spray-dried solid PAC?

A: Spray-dried PAC features a hollow spherical particle structure with a higher specific surface area, resulting in faster dissolution rates and lower insoluble residue. Drum-dried PAC forms larger, flake-like crystals that dissolve slightly slower but are typically more cost-effective for high-volume municipal applications with robust primary mixing tanks.

Q: Does this industrial grade PAC meet drinking water treatment standards?

A: While this grade is formulated and tested for general industrial and municipal wastewater applications, potable water treatment requires specific certification compliance (such as NSF/ANSI Standard 60 or local drinking water chemical standards). Please specify your end-use application during inquiry so our team can provide the appropriate certified grade.

Q: What corrosion-resistant materials are required for PAC storage and dosing systems?

A: Due to the acidic nature of PAC aqueous solutions (pH 3.5 to 5.0), storage tanks and piping systems must be constructed from corrosion-resistant materials. Recommended materials include cross-linked polyethylene (XLPE), fiberglass-reinforced plastic (FRP), PVC, CPVC, or rubber-lined steel. Avoid carbon steel, standard brass, and aluminum components in direct contact with liquid solutions.
