Influence of nanoparticles on the polymer-conditioned dewatering of wastewater sludges
The effect of using small-scale, high surface area, nanoparticles to supplement polymer-conditioned wastewater sludge dewatering was investigated. Aerobically digested sludge and waste activated sludge sourced from the Hunter Valley, NSW, Australia, were tested with titanium dioxide nanoparticles. The sludge samples were dosed with the nanoparticles in an attempt to adsorb a component of the ...

Lab-scaled digestibility study of wastewater sludge treated by thermal hydrolysis
ABSTRACT High-solids mesophilic anaerobic digestion (HS-MAD) processes employing thermal hydrolytic pretreatment (THP) have gained much interest in recent years; primarily because they have been shown to produce Class A biosolids in accordance with EPA 503 regulations, but also because they represent an economical approach to the maximization of available anaerobic digester volume. The ...

What are filter aids?
Filter Aids” is a group of inert materials that can be used in filtration pretreatment. There are two objectives related to the addition of filter aids. One is to form a layer of second medium which protects the basic medium of the system. This is commonly referred to as “precoat”. The second objective of filter aids is to improve the flow rate by decreasing cake compressibility ...

The occurrence and fate of phenolic compounds in a coking wastewater treatment plant
The occurrence of 14 phenolic compounds (PCs) was assessed in the raw, treated wastewater, dewatered sludge and gas samples from a coking wastewater treatment plant (WWTP) in China. It was found that 3-cresol was the dominant compound in the raw coking wastewater with a concentration of 183 mg L−1, and that chlorophenols and nitrophenols were in the level of μg L−1. Phenol ...

Environmental sludge treatment
During the process of wastewater treatment, sludge generation is an important and at times crucial issue to be addressed as inadequate sludge handling system can pose serious environmental implications. Liquid sludge can be easily thickened and reduced to a solid cake via sludge thickening / dewatering. This reduces the volume of liquid sludge significantly, usually resulting in a quite ...
