Global Water Treatment Chemicals

Over the past decade, the global water treatment chemicals market has seen continuous growth driven by environmental mandates, industrial expansion, and rising water scarcity concerns. As a China-based manufacturer with nearly 30 years of production experience, we’ve observed shifting patterns in customer demand across Southeast Asia, Africa, and Latin America — especially in the choice between powdered and granular polyaluminum chloride (PAC).

A Decade in Review (2015–2025)

According to data from UNEP and GWI, the global water treatment chemicals market grew at a CAGR of approximately 6.2% over the past decade. Regional highlights include:

🌏 Rapid industrialization in Southeast Asia (Thailand, Vietnam)

🌍 Growing investment in water infrastructure in Egypt and South Africa

🌎 Rising industrial and agricultural water reclamation in Brazil and Argentina

Environmental regulation has greatly intensified:

The EU’s 2020/75/EU Industrial Emissions Directive introduced stricter limits

ASEAN’s 2024 cross-border water emission framework raised compliance levels

The UN mandates increase reuse of treated wastewater to 60% by 2030

Regional Market Insights & Product Preferences

Southeast Asia (Thailand & Vietnam)

Traditionally dependent on powdered PAC, Southeast Asian industries are now transitioning to granular PAC due to the region’s tropical climate and storage challenges.
A Thai client recently shared:

“Granular PAC gave us faster floc settling and cleaner supernatant — with easier storage during the rainy season.”

Africa (Egypt & South Africa)

Egypt and South Africa prioritize cost-effective water treatment options but are increasingly adopting granular PAC to handle high-turbidity municipal and mining wastewater.

Latin America (Brazil & Argentina)

With fluctuating shipping costs and tightening eco-regulations, Latin American customers now prefer more stable formulations such as granular PAC combined with anionic PAM.

2026 — The Turning Point for Water Treatment Standards

Starting 2026, global environmental requirements will impose:
✅ Stricter COD discharge limits below 30 ppm
✅ High-basicity aluminum coagulants with >85% basicity
✅ Reduction of dust emissions from chemical handling

Why Granular PAC?

✔ High basicity for faster floc formation and dense sludge

✔ Excellent for humid climates and bulk storage

✔ Reduced dust hazard during industrial use

We offer customized PAC grades based on your industry needs — from municipal treatment to mining separation processes.

FAQ

Q1: Why is granular PAC preferred in hot and humid countries?
Because it’s more resistant to caking, reduces waste, and is easier to handle and transport.

Q2: Which industries benefit most from granular PAC?
Municipal water, paper mills, food industry, metal recovery, and other high-turbidity applications.

Q3: Does granular PAC save dosing cost compared with powder?
Yes — it ensures more accurate dosing and minimizes product loss caused by airborne dust.
