Utilization of waste sludge as a renewable resource for energy recovery is the appropriate
solution of how to manage the continuously increasing waste sludge generation effectively …

Our society currently faces three challenges, including resource depletion, waste
accumulation and environmental degradation, leading to rapidly escalating raw material …

Sludge hydrolysate, the byproduct generated during sludge hydrothermal treatment (HT), is
a potential carbon source for biological denitrification. However, the refractory organic …

In order to face excess waste activated sludge management problems, sludge anaerobic
digestion with thermal pre-treatment is of great interest. If most of works agree on the optimal …

In this work, the influence of a low temperature (70–90° C) thermal treatment on anaerobic
digestion is studied. Not only the increase in biogas production is investigated, but attention …

Treatment of municipal wastewater results worldwide in the production of large amounts of
sewage sludge. The major part of the dry matter content of this sludge consists of nontoxic …

The effect of calcium peroxide (CaO 2) addition on anaerobic fermentation of waste
activated sludge (WAS) was investigated. The lab-scale experiments were conducted at 35° …

A potentially practical technology based on ferrate (VI), ie potassium ferrate (PF),
pretreatment integrated into waste activated sludge (WAS) anaerobic fermentation has been …

Sewage sludge disposal and utilization have become an ever-increasing challenge due to
the rapid development of urbanization and strict environmental protection requirements in …

Sewage sludge is considered a costly waste, whose benefit has received a lot of attention
for decades. In this sense, a variety of promising technologies, such as thermal hydrolysis …
