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...

The application of microalgae-based wastewater treatment systems using as a source nutrients has been success-fully developed in recent years and brought about positive results microalgal biomass recovery while producing valuable products. This study presents the microalgae activated sludge (AS) co-culture low agitation photobioreactor (aPBR), which could reduce energy usage. In addition, demon...

Long-term stability of the aerobic granular sludge system is essentially based on microbial community structure biomass. In this study, physicochemical and characteristics wastewater treatment performance were investigated regarding formation, maturation, long-term maintenance granules in two parallel sequencing batch reactors (SBR), R1 R2, under identical conditions. The aim was to explore lin...

Granulation, the process of particle enlargement by agglomeration technique, is one of the most significant unit operations in the production of pharmaceutical dosage forms, mostly tablets and capsules. Granulation process transforms fine powders into free-flowing, dust-free granules that are easy to compress. Nevertheless, granulation poses numerous challenges due to high quality requirement o...

This paper presents a review and findings of the Hybrid Upflow Anaerobic Sludge Blanket (HUASB) technologies, deploying lab scale reactors for treatment domestic industrialwastewater. The major controlling parameters HUASB such as inert media used, pH, temperature, upflow velocity, organic loading, hydraulic residence time along with startup granulation are highlighted its efficient performance...
