In 2024, Liquid held a dominant market position, capturing more than a 67.4% share in the global polyaluminum chloride (PAC) market by form. This significant lead can be attributed to its superior solubility and ease of dosing in large-scale municipal and industrial water treatment plants. Liquid PAC is preferred due to its rapid mixing capabilities, consistent performance, and lower production of sludge compared to powdered alternatives.

The form’s popularity has grown steadily as governments and utilities prioritize efficient water purification systems. With rising investments in water infrastructure across Asia and North America, the demand for liquid PAC is expected to remain strong through 2025, further solidifying its lead in the market.

By Basicity

High Basicity PAC Leads with 47.7% Share in 2024 Driven by Strong Coagulation Efficiency and Lower Sludge Generation

In 2024, High held a dominant market position, capturing more than a 47.7% share in the polyaluminum chloride (PAC) market by basicity. This preference is largely due to its strong coagulation efficiency, especially in drinking water and industrial wastewater treatment. High basicity PAC produces less residual aluminum and reduces sludge volume, making it more economical for long-term operations.

As more water treatment facilities move toward sustainable and cost-efficient practices, the demand for high basicity PAC has remained steady. Going into 2025, this segment is expected to retain its lead, supported by regulatory emphasis on cleaner water output and minimized chemical residuals.

By End-Use

Water Treatment Leads with 37.8% Share in 2024 as Demand for Clean Water Rises Globally
In 2024, Water Treatment held a dominant market position, capturing more than a 37.8% share in the global polyaluminum chloride (PAC) market by end-use. The strong uptake in this segment is driven by increasing urbanization, stricter environmental norms, and growing concerns over access to safe drinking water.

Municipal bodies and industries are relying more on PAC due to its effective coagulating properties and ability to remove turbidity, organic matter, and heavy metals from water sources. This trend has been especially strong in regions like Asia-Pacific and the Middle East, where water scarcity and pollution are pressing challenges. By 2025, the water treatment sector is expected to further boost PAC consumption, backed by infrastructure upgrades and rising global awareness about water quality.

Drivers

Rising Global Demand for Clean Water Fuels Growth in Polyaluminum Chloride (PAC) Market

The escalating global demand for clean and safe water is a significant driver for the growth of the polyaluminum chloride (PAC) market. PAC is extensively utilized in water treatment processes due to its efficiency in coagulating and removing impurities.

The surge in water treatment requirements is not only due to population growth and urbanization but also because of the rising industrial activities that contribute to water pollution. Industries such as food and beverage, pharmaceuticals, and textiles discharge significant amounts of wastewater, necessitating effective treatment solutions. PAC, with its superior coagulating properties, is instrumental in treating such industrial effluents, thereby ensuring compliance with environmental regulations and safeguarding public health.

Government initiatives worldwide are also propelling the demand for PAC. For instance, the Indian government’s Jal Jeevan Mission aims to provide safe and adequate drinking water to all rural households by 2024. Such programs require robust water treatment solutions, thereby increasing the reliance on PAC.

Furthermore, the growing concerns over water scarcity have led to the adoption of advanced water treatment technologies, including desalination and wastewater recycling, where PAC is a critical component. The integration of PAC in these processes enhances the efficiency of contaminant removal, making it indispensable in achieving sustainable water management goals.

Restraints

Environmental Regulations Pose Challenges to Polyaluminum Chloride (PAC) Market Growth

The growth of the polyaluminum chloride (PAC) market is increasingly influenced by stringent environmental regulations aimed at safeguarding ecosystems and public health. While PAC is widely used in water treatment for its efficiency in coagulating impurities, concerns have been raised about its environmental impact, particularly regarding the discharge of untreated wastewater.

A notable instance highlighting these concerns occurred in Ludhiana, India, where the Buddha Dariya Action Front conducted an inspection near the Tajpur dairy complex. The team discovered significant environmental violations, including the direct discharge of untreated wastewater from effluent treatment plants and nearby dairies into the Buddha Dariya river. This not only contravenes environmental regulations but also poses serious risks to aquatic life and public health.

Such incidents underscore the challenges faced by the PAC industry in adhering to environmental standards. Regulatory bodies worldwide are tightening controls on industrial discharges, necessitating investments in advanced treatment technologies and stricter compliance measures. These requirements can increase operational costs for PAC manufacturers and users, potentially affecting market dynamics.

Moreover, the environmental implications of PAC usage extend beyond wastewater discharge. Improper application or accidental releases of concentrated PAC can pose risks to aquatic ecosystems, particularly in sensitive habitats. Therefore, regulatory compliance and proper handling protocols are essential to ensure environmental benefits without compromising ecosystem health.

Opportunity

Government-Led Water Infrastructure Projects Open New Avenues for PAC Market Growth

The expansion of government-led water infrastructure initiatives presents significant growth opportunities for the polyaluminum chloride (PAC) market. PAC is a key coagulant used in water treatment processes, and its demand is closely tied to the development of water supply and sanitation infrastructure.

In India, the Jal Jeevan Mission (JJM) aims to provide tap water to every rural household. As of March 31, 2025, approximately 14.56 crore rural households, representing about 73% coverage, have been connected under this mission. Thirteen states and Union Territories, including Goa, Haryana, Gujarat, and Telangana, have achieved 100% coverage. Additionally, 2.12 lakh villages have been declared “Har Ghar Jal certified,” indicating that every household has a functional tap water connection. To ensure local involvement and monitoring, 6.2 lakh village-level water and sanitation committees have been formed.

These developments underscore the significant role that government initiatives and infrastructure investments play in driving the demand for PAC. As countries continue to prioritize access to clean water, the PAC market is poised for sustained growth.

Trends

Embracing Sustainability: The Shift Towards Eco-Friendly PAC Formulations

A notable trend in the polyaluminum chloride (PAC) market is the increasing emphasis on developing eco-friendly and sustainable formulations. This shift is driven by growing environmental concerns and stringent regulations aimed at reducing the ecological footprint of water treatment processes.

In India, for instance, the Uttar Pradesh Pollution Control Board (UPPCB) reported a 68.8% improvement in water quality across rivers and reservoirs in 2024, compared to the previous year. This improvement is attributed to sustained initiatives, strict monitoring, and environmental campaigns like the Namami Gange Mission and Swachh Bharat Abhiyan.

The state enhanced wastewater treatment infrastructure by establishing 152 sewage treatment plants (STPs), with 141 currently operational and 126 meeting environmental standards. These efforts underscore the importance of effective and environmentally friendly water treatment solutions, such as PAC, in achieving significant water quality improvements.

Furthermore, the global PAC market is experiencing growth due to its superior performance compared to traditional coagulants like alum. PAC’s effectiveness in water and wastewater treatment processes, coupled with increasing urbanization and government initiatives supporting water management projects, is bolstering market expansion.
