The aggregate makes up about 65–75% of the total volume concrete and use artificial aggregates manufactured from waste by-product materials, as an alternative to natural aggregate, has attracted considerable research interest. Washing sludge (WAS) is obtained a during process washing aggregates, which disposed or used landfill. utilization WAS major component manufacture remains unexplored. The...

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...

BACKGROUND, AIM, AND SCOPE Fishery wastewater treatment can be compromised due to seasonal production. The use of sequencing batch reactors is not completely successful, despite flexibility being one of the principal advantages. Most research on activated sludge is performed using synthetic wastewater to ensure a stable and constant feed. The current work compared biomass morphology and settlin...

In this work, three different samples of solid industrial wastes cement kiln dust (CKD), granulated blast furnace slag and marble sludge were employed in a cold bonding pelletization process for the sustainable production of artificial aggregates. The activating action of CKD components on the hydraulic behavior of the slag was explored by evaluating the neo-formed phases present in several hyd...

Municipal sludge is characterized by high organic matter content, viscosity, and fine particles, resulting in poor dewatering performance. This article analyzes the composition properties of municipal sludge, examines factors affecting performance mechanisms corresponding to each influencing factor, introduces chemical conditioning detail. Chemical includes flocculation conditioning, oxidation ...

This study investigates the effects of sieved wastes generated from the brewing industry on lightweight aggregates manufactured with clay. Sludge from a wastewater treatment plant, bagasse and diatomaceous earth were used to obtain the samples. These wastes are usually dumped in landfills, but the current increase in restrictions on dumping and interest in improving the environment make our pro...
