How to use polyacrylamide

Mondo Science Updated on 2024-02-01

Polyacrylamide (PAM) is a polymer with excellent adsorption and sedimentation properties. It is widely used in water purification, soil consolidation, oil extraction and other fields. This article will introduce how to use polyacrylamide.

Polyacrylamide is widely used in water purification, mainly through the following forms:

Polyacrylamide can be added to the suspension as a sedimentation agent, increasing its weight and volume by adsorbing the surface of the suspended solids particles, allowing them to settle quickly to the bottom of the container. This method is suitable for the treatment of suspended solids wastewater and surface water.

Polyacrylamide can be used as a flocculant to treat dissolved particulate matter in water bodies. It is able to adsorb particulate matter and make it form larger particles that facilitate sedimentation or filtration. In addition, polyacrylamide can also promote the aggregation and violent collision of bubbles, thereby improving the bubble adhesion effect.

The application of polyacrylamide in soil consolidation mainly includes the following aspects:

Polyacrylamide can be added to the soil as a plugging agent for loose soils, forming colloids through interaction with soil particles, thereby improving the strength and stability of the soil.

Polyacrylamide can form a stable colloidal film in the soil, preventing the flow of soil particles, thereby preventing soil dam failure.

Polyacrylamide plays an important role in oil extraction, and it is mainly used in the following two aspects:

Polyacrylamide can be used as a conditioner in oilfield wastewater to adjust the pH value and dissolved oxygen content in the wastewater, thereby improving water quality.

Polyacrylamide can be used as a modification agent to improve oil-water separation in aquifers. It can effectively reduce the permeability resistance in the aquifer and increase the production of oil wells.

Polyacrylamide has a wide range of applications in water purification, soil consolidation, and oil extraction. When using polyacrylamide, the appropriate method of use should be selected according to the specific needs and conditions, and the operation should be carried out in accordance with the relevant regulations and standards.
