Do polyaluminium chloride and anionic polyacrylamide water treatment residuals adsorb phosphorus?

Polyaluminium chloride and anionic polyacrylamide water treatment residuals (PAC-APAM WTRs) as an amendment in three types of soils with the ratios (w/w) of 10%, 15%, and 20% were evaluated for phosphorus adsorption from aqueous solutions by batch studies.

Are Pac-Apam WTRS effective in soil based phosphorus immobilization?

Although this study confirmed that PAC-APAM WTRs are an appropriate candidate as an effective amendment in the soils for immobilizing phosphorus, further studies are required for the ultimate application of PAC-APAM WTRs in the traditional soil-based media of SWBR systems.

What does PAC stand for in water treatment?

With improvement and upgrade of technologies and processes in drinking water treatment, more and more water treatment plants use polyaluminium chloride (PAC) as a coagulant in coagulation and sedimentation units and anionic polyacrylamide (APAM) as a dewatering agent in sludge handling units (Duan et al., 2022).

Does phosphorus adsorption improve stormwater runoff performance after Pac-Apam WTR addition?

Despite improving the phosphorus removal capacity after PAC-APAM WTRs addition in soils, further studies are required including phosphorus adsorption performance in real stormwater runoff in SWBR systems with intermittent unsaturated and saturated flows.
