The successful management of wastewater sludge for small-scale, urban wastewater treatment plants, (WWTPs), faces several financial and environmental challenges. Common management strategies stabilize sludge for land disposal by microbial processes or heat. Such approaches require large footprint processing facilities or high energy costs. A new approach considers converting sludge to fuel whic...

This work illustrates that the removal of some endocrine-disrupting compounds from sewage treatment works effluent is dependent on parameters such as sludge age, influent concentrations, concentrations of co-pollutants and hydraulic retention time as well as physicochemical properties of the compound. Greater nonylphenol polyethoxylates (NPEO) and polybrominated diphenyl ether (PBDE) removal wa...

Connecting earthquake nucleation in basement rock to fluid injection basal, sedimentary reservoirs, depends heavily on choices related the poroelastic properties of fluid-rock system, thermo-chemical effects notwithstanding. Direct constraints these parameters outside laboratory settings are rare, and it is commonly assumed that layers isotropic. With Arbuckle wastewater disposal reservoir Osag...

The conventional sludge disposal options include landfill, application to farmland and forestry and incineration. However, since in the last decade sewage sludge and industrial sludge are being generated in increasing amounts due to the rapid urbanization and industrialization, a growing interest has been devoted in developing cost effective and renewable disposal alternatives. Among them, the ...

Sludge produced in wastewater treatment plants (WWTPs) reaches around 1% of the wastewater volume treated whilst the processes for sludge handling and disposal represent from 20 to 60% of operating costs. It is widely recognised that sludge for disposal is one of the most critical issues today for WWTPs operators. The tendency of many countries seems to be aimed towards a biowaste prevention wh...

Dissolving pulp mill wastewater called prehydrolysis liquor (PHL) obtained from steam (at 150-170C) treatment of wood had a total chemical oxygen demand (COD) of approximately 100 g/L contains mainly sugars, furfural, lignin, and acetic acid, poses a considerable wastewater disposal problem. Replacement of the current energy intensive disposal method (evaporation and use of recovery boiler) is ...
