Wastewater sludge is mostly water—typically 97% to 99.5%. Handling and disposing of this vast volume of liquid is incredibly inefficient and expensive. The primary goal of sludge filtration is simple ...

This is the second of three stories, explaining the process of water and wastewater treatment for the City of Kamiah.

The city reported a more than $2.7 million balance for contingencies that may arise from its $68 million project to close out the consent decree its wastewater system has been under for more than a ...

Effective wastewater treatment relies on the recycling of activated sludge (RAS) to sustain microbial activity in aeration tanks. Future developments aim to address issues like microplastic clogging ...

This study investigates the impact of loosely bound (LB-) and tightly bound (TB-) polymeric substances (PS) on bioflocculation and organic matter harvesting in High Rate Activated Sludge (HRAS) ...

This process involves aggregating sludge into dense flocs with low SVI30 values, utilizing equipment such as hydrocyclones and centrifuges, and applying chemicals like chlorine or biocides to prevent ...

Hydrolysis of recalcitrant organic waste such as lignocellulosic biomass and waste-activated sludge (WAS) is a rate-limited step in anaerobic digestion (AD) due to the chemical and physical barriers ...
