1. Product Introduction & Main Application
Arnico’s Polyacrylamide (PAM) is a high molecular weight, linear water-soluble polymer available in anionic, cationic, and non-ionic grades. Serving as a powerful flocculant, coagulant, and viscosity enhancer, this material plays a critical role in water treatment and solid-liquid separation processes, helping to reduce sludge volume and improve the efficiency of industrial systems.

3. Features & Benefits
-
Rapid & Robust Flocculation: Forms large, dense, and shear-resistant flocs, dramatically increasing settling velocity and separation efficiency.
-
Ultra-Low Dosage Requirement: Delivers high performance at very low concentrations (a few ppm), leading to significant economic savings.
-
Excellent Solubility: The powder is specifically designed for rapid dissolution without the formation of “fish-eyes” (unhydrated gel lumps) in water.
-
Grade Versatility: Anionic grades are tailored for mineral-rich, positively charged effluents, while cationic grades target organic, negatively charged biological sludges.
4. Industrial Applications
-
Water & Wastewater Treatment: Primary separating agent for municipal and industrial sludge in centrifuges and filter presses.
-
Mining & Flotation: Improves tailings settling and enables efficient water recovery from mineral thickeners.
-
Paper Industry: Acts as a retention and drainage aid for fibers and fillers, and as a flocculant for mill wastewater.
-
Oil & Gas Drilling: Enhances drilling fluid viscosity (EOR) and reduces fluid loss into the formation.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): The dry powder is non-toxic, but wetted surfaces become extremely slippery. Complete MSDS documentation is available upon request.
-
Storage Conditions: Store in a dry, cool place (below 30°C), away from moisture and freezing conditions. Opened bags must be resealed in airtight, moisture-resistant containers.
-
Personal Protective Equipment (PPE): When handling the powder, the use of a dust mask and safety goggles is recommended. Avoid wearing smooth-soled shoes.
6. Quality Assurance & COA
All Arnico Polyacrylamide grades are supplied with a unique Certificate of Analysis (COA) detailing precise viscosity, dissolution time, and ionic charge percentage, enabling customers to achieve the optimal match for their sludge dewatering process.
