Can polyaluminium water treatment sludge be used as a flocculant aid?

In this study, the reuse of polyaluminium water treatment sludge (PA-WTS) as a flocculant aid to improve the effluent quality of wastewater during primary sedimentation is evaluated and presented. PA-WTS was collected from Gabba water treatment plant (Gabba WTP) Uganda, after the coagulation…

Is poly-aluminum chloride a good coagulant for wastewater treatment?

As a common and low-cost coagulant, poly-aluminum chloride (PAC) may be widely used for wastewater treatment. In this article, the impacts of PAC on activated sludge and the treatment efficiency of sequencing batch reactor were investigated over 100 d for domestic wastewater treatment.

What is polyaluminum water treatment sludge (PA-WTS)?

hereafter referred to as polyaluminium water treatment sludge (PA-WTS), which poses a challenge to dispose. From a chemical point of view, polyaluminum chloride (PAC) is similar to alum, except that the former contains highly charged polymeric aluminium species as well as the monomers. The solubility charact

Does residual aluminum salt coagulant affect activated sludge production?

Understanding the effect of residual aluminum salt coagulant on activated sludge in sequencing batch reactor: Performance response, activity restoration and microbial community evolution. The economic potential of poly-aluminum chloride (PAC) at full-scale sludge treatment plant and its impact on sludge production was explored in this study.

Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?

At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.
