Pilot-plant studies were conducted on zeolite type A, an alternative detergent builder, over a range of concentrations expected in settled wastewater and at two degrees of calcium exchange for sodium ...

In this study biokinetic and microbial growth coefficients for nitrate versus oxygen respiration in the activated sludge process were evaluated and compared. Two bench-scale activated sludge units ...

A global study expands the understanding of activated sludge microbiomes for next-generation wastewater treatment and reuse systems enhanced by microbiome engineering. Wastewater treatment and reuse ...

To better achieve environmental goals, a growing number of wastewater treatment plants (WWTPs) are being retrofitted from the conventional activated sludge (CAS) process to the membrane bioreactor ...

The efficient running of wastewater treatment plants is an essential part of modern society. Just like humans, wastewater treatment plants can get sick, due to viral attacks. Now, new research from ...
