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.

Does poly-aluminum chloride affect sludge production?

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. The effect of recycling water on major… Effects of Al3+ on the microstructure and bioflocculation of anoxic sludge. International Journal of Environmental Science…

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.

Can polyaluminium water treatment sludge be reused as a floccula?

ducts, hence, reuse of these wastes is a major contributor to sustaining fresh water for the coming decades. In this study, the reuse of polyaluminium water treatment sludge (PA-WTS) as a floccula

What is waste activated sludge (WWTP)?

As a byproduct of biological wastewater treatment, large amounts of waste activated sludge (WAS) are inevitably produced, which is becoming a big problem faced by wastewater treatment plants (WWTP) nowadays , . WAS is one typical type of solid wastes and easily causes secondary pollution if it is treated inappropriately.
