Transformation of industrial sludges into vermicompost is of double interest: on the one hand, a waste is converted into value added product, and, on the other, it controls a pollutant that is a consequence of increasing industrialization. This paper reports the feasibility of utilization of vermicomposting technology for nutrient recovery from industrial sludge in laboratory scale experiment e...

This paper deals with thermal drying of wastewater sludges, whose management will become crucial in the forthcoming years. Sludges collected after mechanical dewatering in 5 different WWTPs are submitted to the same convective drying treatment in order to try finding some relations between the drying behaviours, the type of effluent and wastewater treatments. Results show dearly sludge drying r...

Sequencing batch reactor (SBR) is one of several periodically operated, suspended-growth activated sludge system. It has an advantage for nitrogen removal which is difficult to remove with conventional system. This paper reviewed the nitrogen removal performance in SBR for several different industrial wastewaters and discussed the factors which may affect the treatment performance. Several modi...

This study aimed to produce bacterial cellulose from paper waste sludge (PWS) as a method of utilizing the source remaining pulp in material. Initially, PWS was hydrolyzed by sulfuric acid create an enriched-reducing sugar hydrolysate. One-factor experiments were conducted with fixed amount (5 g) investigate influence hydrolysis conditions, including water, addition, temperature, and retention ...

Pulsed Electric Field (PEF) processing works through the process of electroporation in cells – destroying the cell membranes through the application of short, very high voltage pulses across a liquid. PEF processing can also improve the performance of industrial processes such as the removal of water from sludge, or the extraction of oils, sugars, or starches from plants, because the ruptured c...

In most empirical applications, forecasting models for the analysis of industrial land focus on the relationship between current values of economic parameters and industrial land use. This paper aims to test this assumption by focusing on the dynamic relationship between current and lagged values of the 'economic fundamentals' and industrial land development. Not much effort has yet been attrib...
