About Polyacrylamide

One of the largest uses for polyacrylamide is to flocculate solids in a liquid. This process applies to water treatment, and processes like paper making, Screen Printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer.Another common use of polyacrylamide and its derivatives is in subsurface applications such as Enhanced Oil Recovery.

Excellent Flocculant for Industrial Applications

Polyacrylamides superior flocculating and thickening abilities make it indispensable in sectors such as wastewater treatment, paper production, and oil extraction. Its efficacy stems from its high molecular weight and solubility in water, efficiently aggregating suspended particles and facilitating their removal.

Versatile Forms and Easy Application

Available in powder, granule, and gel forms, Polyacrylamide can be tailored to various industrial processes. Its rapid dissolution and neutral pH suit diverse applications, whether as a liquid solution or dry powder added directly to systems.

FAQs of Polyacrylamide:

Q: How is Polyacrylamide used in water treatment processes?

A: Polyacrylamide acts as a flocculant in water treatment, aggregating suspended solids so they can be easily removed from wastewater, resulting in clearer, cleaner water.

Q: What benefits does Polyacrylamide offer in industrial applications?

A: It delivers efficient particle aggregation, enhances filtration and sedimentation, optimizes viscosity for manufacturing processes, and improves yields in applications such as oil recovery and paper making.

Q: When should Polyacrylamide be added during an industrial process?

A: It is typically introduced at the stage where solids need to be separated, such as during wastewater clarification or pulp formation in paper manufacturing. The exact timing varies according to process and equipment setup.

Q: Where should Polyacrylamide be stored for optimal shelf life?

A: Store Polyacrylamide in a cool, dry place away from moisture and direct sunlight to maintain its quality and extend its shelf life up to 24 months.

Q: What is the recommended usage concentration for Polyacrylamide in solutions?

A: The concentration depends on the targeted process and contaminants, but it is commonly used in low concentrations ranging from 0.01% to 1% in water-based solutions.

Q: Is Polyacrylamide safe for use in food or cosmetic applications?

A: When produced to food or cosmetic grade standards and used within regulatory guidelines, Polyacrylamide is considered safe for these applications. However, always confirm compliance with local regulations.
