Can polyaluminium chloride be used as a coagulant in biodiesel wastewater?

In this study, coagulation and flocculation process was used to treat a biodiesel wastewater with polyaluminium chloride as a coagulant. The improvement of the process by using anionic as coagulant aids was also investigated.

Does alum cationic polymer reduce the cost of wastewater treatment?

It was also reported in this research that by application of the alum-cationic polymer combination, the cost for treatment of one cubic meter of wastewater reduced 50 percent compared with application of alum–alone method (Haydar and Aziz 2009b).

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 polymers be used with Pac coagulant for ceramic wastewater treatment?

The purpose of this stage of jar-test experiment was to identify the suitable dose of polymers, which could be used in combination with optimal dose of PAC coagulant (300 mg/L) for treatment of the ceramic wastewater. The applied polymer dose varied from 0.5 to 3 mg/L.

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.

Why is polyaluminum chloride a good coagulant?

Polyaluminum chloride (PAC) has grown to be the most widely used coagulant because of the benefits over traditional aluminum or ferric-based coagulants, such as less aluminum residuals, better performance at low temperature, less effect on the pH value of water, rapid flocculation, and less sludge volume (Wei et al., 2015).
