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.

Can polyaluminium chloride and anionic polyacrylamide remove CD 2+ and Zn 2+?

Water treatment residuals produced after addition of polyaluminium chloride and anionic polyacrylamide (PAC-APAM WTRs) were evaluated for the potential to remove Cd 2+ and Zn 2+ from aqueous solutions by batch adsorption studies.

Can anionic polyacrylamide be used as a coagulant in water treatment sludge?

Also, using anionic polyacrylamide (APAM) as a coagulant in the dewatering process of water treatment sludge has been a regular practice to accelerate the dewatering process and decrease the size of dewatering tanks or ponds in large-scale drinking water treatment plants.

Is polyaluminium chloride a coagulant?

Meanwhile, polyaluminium chloride (PAC) is increasingly being used as the coagulant to replace the traditional Al-salt based coagulant around the world.

Can PAC-Apam sorbent be applied to heavy metal contaminated soil?

Generally, the application of such a type of sorbent is realized by land applying PAC-APAM WTRs into heavy metal contaminated soils for the soil remediation. The limitation of current soil remediation approaches is the cost and the potential ecological risks.

Can PAC-Apam adsorbent be used for soil remediation?

The limitation of current soil remediation approaches is the cost and the potential ecological risks. Using PAC-APAM WTRs as the adsorbent for soil remediation can reduce the cost of long-distance transportation and landfilling of the WTRs but also reduce the space occupied by the land resources required for their disposal.
