Pulp and Paper Industry
Brazil is one of the world’s largest pulp producers and a major player in the global paper industry. States like São Paulo, Paraná, Santa Catarina, and Bahia host large pulp and paper operations. The industry is water-intensive and generates significant volumes of wastewater that require careful treatment.
Process Water and White Water Treatment
In pulp and paper mills, water is used throughout the production process — from pulping to bleaching to paper forming. Polyaluminum chloride is used for raw water treatment entering the mill, while polyacrylamides serve as retention aids, drainage aids, and flocculants in the papermaking process itself.
Cationic polyacrylamides are widely used as retention aids to improve fiber and filler retention on the paper machine wire, reducing raw material losses and improving paper quality. The selection of the right PAM molecular weight and charge density is critical for optimal performance in paper retention applications.
Effluent Treatment in Pulp and Paper
Pulp and paper effluent is characterized by high COD, BOD, color, and suspended solids. Kraft pulping processes also generate lignin compounds and chlorinated organic compounds from bleaching operations. Treatment typically involves:
- Primary treatment with screening, sedimentation, and coagulation-flocculation using PAC and PAM
- Secondary biological treatment using activated sludge or anaerobic systems
- Tertiary treatment with dissolved air flotation (DAF), activated carbon, or advanced oxidation for color and residual COD removal
Anionic PAM is commonly used in primary clarification and sludge dewatering, while cationic PAM is used in DAF units and belt filter presses. The high volume of effluent generated by pulp mills means even small improvements in chemical efficiency can result in significant cost savings.
Mining and Tailings Treatment
Brazil is a global mining powerhouse, producing iron ore, bauxite, gold, copper, manganese, and other minerals. Mining operations consume enormous volumes of water and generate tailings — fine-grained waste material suspended in water that must be clarified and managed safely.
Anionic polyacrylamides are the workhorse chemicals in mining tailings treatment. They are used to:
- Flocculate tailings in thickeners and clarifiers to increase settling rate and improve underflow density
- Improve water recovery for reuse in mineral processing operations
- Enhance tailings dewatering in belt presses, centrifuges, or filter presses for dry stacking
- Reduce turbidity in process water and effluent discharge
High-molecular-weight anionic PAM is typically preferred for tailings applications due to its ability to bridge between fine particles and form strong, rapidly settling flocs. The choice of anionic, cationic, or nonionic PAM depends on the specific mineralogy and process conditions.
Brazil’s mining sector has faced increased scrutiny following high-profile tailings dam failures, leading to stricter regulations and increased investment in tailings management technologies. This trend drives demand for high-performance flocculants and dewatering chemicals.
Municipal Water and Wastewater
Brazil’s municipal water sector serves over 215 million people across 5,568 municipalities. While water supply coverage is relatively high (around 95%), wastewater treatment coverage lags significantly, with only about 55-60% of municipal wastewater receiving treatment. The federal government’s Sanitation Legal Framework (Marco Legal do Saneamento Básico) aims to universalize water and wastewater services by 2033.
Polyaluminum chloride is increasingly used in Brazilian drinking water treatment plants, replacing traditional aluminum sulfate in many systems due to its superior performance and wider pH range. The complete guide to coagulant types provides a useful comparison for plant operators evaluating options.
In municipal wastewater treatment, PAC is used for enhanced primary treatment and phosphorus removal, while cationic PAM is the standard chemical for sludge dewatering in belt filter presses and centrifuges. Our article on municipal wastewater treatment provides more details on coagulation in municipal applications.
Import Regulations and Quality Standards
Importing water treatment chemicals into Brazil requires navigating a complex regulatory environment. Key agencies and requirements include:
ANVISA Registration
Chemicals used in drinking water treatment must be registered with ANVISA (National Health Surveillance Agency), Brazil’s equivalent of the FDA. The registration process involves submitting detailed product information, toxicological data, and manufacturing process documentation. ANVISA certification is a prerequisite for supplying drinking water utilities.
Environmental Regulations
CONAMA (National Environment Council) sets national environmental standards, including wastewater discharge limits. State-level environmental agencies like CETESB in São Paulo enforce these standards and may have additional state-level requirements. Industrial effluent discharge permits are required for most manufacturing operations.
Import Duties and Taxes
Import duties on water treatment chemicals vary by product classification and can be substantial. The Mercosur Common External Tariff (TEC) applies to imports from non-Mercosur countries. In addition to import duties, importers must pay ICMS (state VAT), IPI (federal tax), and PIS/COFINS social contributions. Understanding the total landed cost is essential for competitive pricing.

Product Specifications for the Brazilian Market
Brazilian customers have specific quality expectations that vary by sector. Typical specifications for major water treatment chemicals include:
| Product | Typical Form | Key Specifications |
|---|---|---|
| PAC | Liquid and powder | 10-17% Al2O3 (liquid), 28-30% Al2O3 (powder), basicity 30-50% |
| Anionic PAM | Powder/emulsion | High MW, various charge densities, 88-90% purity |
| Cationic PAM | Powder/emulsion | Various charge densities, medium-high MW, 88-90% purity |
