Does polyaluminum chloride remove color from landfill leachate?

Treatment of landfill leachate is essential as it could threaten the surrounding ecosystem. The aim of this research was to determine the efficiency of polyaluminum chloride (PACl) in removing chemical oxygen demand (COD), ammoniacal nitrogen (NH 3 -N) and color from two different landfill sites in Malaysia.

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.

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.

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.

What is a municipal solid waste (WTR)?

WTRs are municipal solid wastes derived from the coagulation, flocculation, and sedimentation processes in drinking water treatment plants. Globally, the production of the dewatered WTRs has sharply increased due to the rapid urbanization and population increase as well as the improved quality of life expectations in recent years.

Are heavy metal ions a problem in soil remediation?

Heavy metal ions such as Cd 2+ and Zn 2+ are primary concerns in soil remediation (Xue et al. 2009). Most of the heavy metal ions are inherently present in soil at varying background levels (Wu et al. 2018). Various anthropogenic activities cause an increase in their concentrations in soils (Wu et al. 2018).
