II. What is Iron-Free Aluminium Sulfate?

Iron-Free Aluminium Sulfate is an inorganic aluminium salt product with aluminium sulfate as its main component and strictly controlled iron impurity indicators.

Its chemical molecular formula is Al2SO4_3, and its CAS number is 10043-01-3. The product usually exists in a solid form containing crystal water, with a white or off-white appearance, and can be manufactured into powder, flake, lump, and granular forms.

Iron-free aluminium sulfate is easily soluble in water, and its aqueous solution is acidic. In the field of water treatment, it can be used as an aluminium salt coagulant; in paper manufacturing, titanium dioxide post-treatment, and other industrial production, it can also serve as a corresponding chemical raw material.

The term "Iron-Free" in the product name is a product category designation. The actual ferric oxide content should be based on specific technical indicators and batch test results, and does not imply that the iron content is absolutely zero.

2.1 Basic Product Information

III. Iron-Free Aluminium Sulfate Technical Parameters: Alumina, Ferric Oxide, and Water-Insoluble Matter Indicators

When procuring iron-free aluminium sulfate, one should not only focus on the product name and price per ton, but also comprehensively compare parameters such as alumina content, ferric oxide content, pH value, and water-insoluble matter.

ECOLINK TECHNOLOGY provides two specifications, 16% and 17%. The specific technical parameters are as follows:

3.1 Product Quality Indicators

Note: The above data is compiled according to the product technical parameter sheet on the official website. Actual supply indicators and batch testing results are subject to the product specifications and COA confirmed by both parties.

3.2 Alumina Content (Al2O3)

Alumina content is one of the important indicators for measuring the active component of aluminium sulfate products.

Currently, the product is offered in two specifications:

16% Specification: (Al2O3) content is 16.15%.

17% Specification: (Al2O3) content is 17.05%.

Alumina content affects the amount of aluminium components provided per unit of product. When selecting different specifications, customers should perform a comprehensive comparison considering the procurement price, active component content, and actual process requirements.

3.3 Ferric Oxide Content(Fe2O3)

Ferric oxide content is a quality parameter requiring key attention during the procurement of iron-free aluminium sulfate.

The (Fe2O3) contents for the two specifications are 0.0021% and 0.0035%, respectively. For production processes such as paper manufacturing and titanium dioxide post-treatment that demand high whiteness and minimal raw material impurities, the ferric oxide content is a critical reference item for raw material acceptance.

Customers are advised to clarify their (Fe2O3) indicator requirements during procurement and verify them against the actual batch COA.

3.4 Water-Insoluble Matter

Water-insoluble matter is an important parameter for evaluating insoluble residues in aluminium sulfate solutions.

If there are excessive insoluble impurities after dissolution, it may increase sediment residue in the solution, affecting certain production processes that demand high solution clarity.

According to official parameters:

16% Specification: Water-insoluble matter is 0.026%.

17% Specification: Water-insoluble matter is 0.032%.

Customers can determine corresponding requirements based on their own production processes, solution preparation methods, and quality acceptance standards.

3.5 pH Value

When aluminium sulfate dissolves in water, the aqueous solution is acidic. In the product parameters, the pH value of the 16% specification is 3.15, and that of the 17% specification is 3.5.

In water treatment processes, the hydrolysis of aluminium sulfate consumes part of the alkalinity in water, which may lead to a decrease in water pH. Therefore, the actual coagulation effect is not only related to the product's own parameters, but is also influenced by factors such as raw water pH, alkalinity, turbidity, and water temperature.

IV. Working Principle of Iron-Free Aluminium Sulfate: Coagulation and Flocculation Processes in Water Treatment

Aluminium sulfate is a common inorganic aluminium salt coagulant. In the water treatment process, after the product dissolves, aluminium ions undergo a hydrolysis reaction to form various species of hydrolysis products.

Under suitable pH and water quality conditions, these hydrolysis products promote the aggregation of colloidal particles and suspended solids in water through charge neutralization, adsorption, and micro-floc formation. The aggregated particles are then separated through sedimentation or filtration.

4.1 Charge Neutralization

Some colloidal particles in raw water carry identical or similar surface charges, creating electrostatic repulsion between particles that prevents natural aggregation.

The charged hydrolysis species formed after aluminium sulfate dissolves can reduce the electrostatic repulsion between particles, facilitating contact and aggregation among fine particles.

4.2 Adsorption and Floc Formation

Aluminium salt hydrolysis products can adsorb some of the colloidal particles and fine suspended solids in water, promoting the formation of larger flocs among the particles.

4.3 Floc Settlement and Solid-Liquid Separation

Under suitable coagulation and flocculation conditions, the formed flocs can be removed from water through sedimentation or other solid-liquid separation processes, thereby improving effluent clarity.

4.4 Impact of pH and Alkalinity on Coagulation Effect

The hydrolysis process of aluminium sulfate consumes alkalinity in water. If the raw water alkalinity is insufficient, dosing aluminium sulfate may cause the water pH to drop, which in turn affects the formation of aluminium hydrolysis products and the overall coagulation efficiency.

Therefore, in actual water treatment projects, comprehensive consideration must be given to:

Raw water turbidity;

Raw water pH;

Raw water alkalinity;

Water temperature;

Coagulant dosage;

Rapid mixing and flocculation conditions;

Subsequent sedimentation and filtration processes.

It is recommended to determine reasonable chemical dosages and operational conditions through Jar Tests, rather than relying on a fixed dosage.

V. Main Application Fields of Iron-Free Aluminium Sulfate

Iron-Free Aluminium Sulfate features a low ferric oxide indicator and can be applied in water treatment, paper manufacturing, titanium dioxide post-treatment, and other industrial production fields according to specific process requirements.

5.1 Drinking Water Treatment

During drinking water treatment, raw water may contain silt, suspended particles, and colloidal substances. These fine particles do not easily settle naturally and require treatment through coagulation, flocculation, sedimentation, and filtration processes.

The hydrolysis products formed after aluminium sulfate dissolves promote the aggregation of suspended particles and colloids into larger flocs, which are subsequently removed through sedimentation and filtration.

Common Customer Issues:

Large fluctuations in raw water turbidity leading to unstable coagulation performance;

Excessively high chemical dosages increasing operational costs;

Insufficient raw water pH or alkalinity affecting coagulation efficiency;

Small flocs or slow settling velocity;

Iron impurity indicators of ordinary aluminium sulfate failing to meet specific project requirements.

Product Selection Recommendations: In drinking water treatment projects, it is recommended to focus on parameters such as Al2O3, Fe2O3, and water-insoluble matter, and perform product selection based on raw water quality.

ECOLINK TECHNOLOGY can assist in discussing product specifications and application testing plans based on customer-provided raw water turbidity, pH, alkalinity, and treatment process parameters.

Special Note: Whether a specific product can be used for drinking water treatment depends on compliance with relevant regulations, applicable standards, and hygienic requirements of the target market, as well as necessary water quality validations. Suitability for drinking water cannot be judged solely by product name or a single indicator.

5.2 Industrial Wastewater Treatment

Industrial wastewater typically contains suspended solids, colloidal particles, and other pollutants. Since wastewater composition varies significantly across different production processes, the choice of coagulant and dosage must be determined based on actual water quality.

Iron-free aluminium sulfate can be used for coagulation and sedimentation pretreatment of certain industrial wastewaters, promoting suspended particle aggregation and improving downstream solid-liquid separation conditions.

Common Application Scenarios:

Pretreatment of textile dyeing wastewater;

Coagulation and sedimentation of paper mill wastewater;

General industrial manufacturing wastewater treatment;

Coagulation treatment of industrial wastewater containing suspended solids;

Treatment of certain industrial circulating water and process water.

Common Issues in Industrial Wastewater Treatment:

Issue 1: High Chemical Dosage May be related to fluctuations in raw water quality, dosage solution concentration, pH conditions, or mismatched mixing intensity. Recommendation: Perform Jar Tests under varying dosages and pH conditions to compare floc formation, settling behavior, and effluent parameters to identify an optimal dosing scheme.

Issue 2: Small Flocs and Suboptimal Settling Effect May be due to improper coagulant dosage, unreasonable rapid mixing conditions, or the presence of fine, hard-to-settle particles in the wastewater. Recommendation: Optimize by adjusting chemical dosage, mixing parameters, and flocculation time. When necessary, evaluate the feasibility of dual dosing with Polyacrylamide (PAM).

Issue 3: Variations in Treatment Performance Across Batches Recommendation: Pay close attention to indicators like Al2O3, Fe2O3, and water-insoluble matter during procurement and application, and analyze performance alongside on-site operational data.

Proper use of aluminium sulfate helps improve coagulation and sedimentation performance in industrial wastewater, creating favorable conditions for subsequent filtration, biological treatment, or advanced treatment.

5.3 Paper Manufacturing

Aluminium sulfate is a common inorganic chemical raw material in the paper industry, widely used in paper sizing systems and related manufacturing processes.

In papermaking, aluminium sulfate participates in the chemical equilibrium of the sizing system, helps regulate the ionic environment in the system, and works in synergy with other papermaking auxiliaries.

Key Quality Indicators for Paper Mills:

Whether the ferric oxide content meets paper whiteness and raw material purity standards;

Whether water-insoluble matter increases the impurity load on the production system;

Whether the alumina content satisfies production formula requirements;

Whether product indicators remain stable across different batches;

Whether product dissolution and feeding methods are compatible with existing equipment.

For papermaking processes with strict whiteness and raw material purity demands, iron-free aluminium sulfate serves as an ideal raw material option. The actual application performance also depends on pulp properties, sizing agent types, system pH, addition sequence, and operating conditions.

5.4 Titanium Dioxide Post-Treatment

Iron-free aluminium sulfate can be used as an industrial chemical raw material in processes related to titanium dioxide post-treatment.

Titanium dioxide and other products sensitive to whiteness, color, and impurity levels have strict requirements regarding raw material quality. Therefore, during raw material procurement, ferric oxide content, alumina content, and water-insoluble matter are all vital parameters to monitor.

Common Customer Concerns:

Whether iron impurities affect the color and purity specifications of the final product;

Whether different alumina contents fit existing production formulations;

Whether water-insoluble matter impacts material uniformity in certain processes;

Whether raw material batch variations affect continuous production management.

It is recommended that customers conduct laboratory or pilot tests according to their specific titanium dioxide post-treatment process before confirming bulk procurement specifications.
