Ultrasound irradiation has been gaining increasing interests over the years to assist
biological conversion of lignocellulosic biomass and waste materials to biofuels. As such …

In the context of climate policies that advocate carbon neutrality, carbon emission reduction
provides a new restriction in evaluating the waste activated sludge (WAS) treatment …

A significant ecological problem was developed on disposing the enormous amounts of
waste activated sludge (WAS) produced by traditional wastewater treatment. There have …

A sludge process reduction activated sludge (SPRAS), with a sludge process reduction
module composed of a micro-aerobic tank and a settler positioned before conventional …

Anaerobic digestion (AD) is an effective approach for waste activated sludge (WAS) disposal
with substantial recovery of valuable substrates. Previous studies have extensively explored …

This study proposed a new technology, ie, ultrasound (US)-enhanced peracetic acid (PAA)
