Fluence Corp. Limited, a global provider of distributed water and wastewater treatment solutions, through its Argentina-based South American subsidiary, has been awarded a $2.5 million turnkey contract to provide a high-efficiency wastewater and reuse treatment plant. The customer, a provider in the food and beverage industry, has selected Fluence Argentina to carry out this project with an
The Carrousel System utilizes the Modified Lutzack-Ettinger (MLE) configuration for highly efficient denitrification. This process is known as the denitIR® System, where internal recycle (IR) flow is directed into the anoxic zone via a slip-stream channel using propulsion generated by the Excell Aerator.

Cationic Polymers as Organic Coagulants in Water Treatment at Heat and Electric Power Plants Article (PDF Available) in Russian Journal of Applied Chemistry 76(12):1951-1954 · December 2003
Polyacrylamide is not the only acrylamide unit, the acrylamide unit is mostly called polyacrylamide. Thus, polyacrylamide may contain structural units that can be ionized or hydrolyzed in water to carry charges. As a result, there are cationic, anionic, non-ionic, amphoteric ion type of various polyacrylamide anionic polyacrylamide
Technical Guidance for the Use of Polyacrylamides (PAM) and PAM-blends for Erosion Control and Storm Water Clarification Practice Description PAM is a water-soluble anionic polyacrylamide product used to minimize soil erosion caused by water and wind to decrease soil sealing by binding soil particles, especially clays, to hold them on site.
Summary Hydrolysis of polyacrylamide (PAM) -based polymers is rapid and extensive under the alkaline conditions typical of alkaline/surfactant-polymer (ASP) flooding. Even at room temperature, significant hydrolysis occurs within 1 to 2 months in th

Soil erosion affects soil productivity and environmental quality. A laboratory research experiment under simulated heavy rainfall with tap water was conducted to investigate the effects of anionic polyacrylamide (PAM) application rates (0, 0.5, 1.0, and 2.0 g m −2) and molecular weights (12 and 18 Mg mol −1) on runoff, soil erosion, and soil nutrient loss at a slope of 5°.
The nutrient loss caused by soil erosion is the main reason for soil degradation and environmental pollution, and polyacrylamide (PAM) as a common soil amendment has a great influence on runoff
