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 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.

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).

What is anionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) possesses interconnected and active groups that establish robust bonds with the surface of suspended colloids, promoting the formation of coarse particles among the suspended solids and a mixture of insoluble particles in water (Irfan et al. 2017).

How to use polyaluminum chloride?

Usage :1. Dissolve solid polyaluminum chloride into liquid by adding 1:3 water, and then dilute it with 10-30 times water to the required concentration before use. 2, dosage can be determined according to the different turbidity of raw water, the best dosage, generally raw water turbidity in 100-500mg/L, each thousand tons of dosage is 10-20kg.

Can Pam be used for sludge dewatering?

PAM can be used for sludge dewatering; In industrial water treatment, mainly used as a formula. In the raw water In treatment, using organic flocculant PAM instead of inorganic flocculant, the water purification capacity can be increased by more than 20% even if the sedimentation tank is not reformed.
