Environmental effects of using clay bricks produced with sewage sludge: leachability and toxicity studies.
Use of sewage sludge from wastewater treatment plants as a raw material for making clay bricks has been analyzed to be an option to dumping sludges into landfills. This alternative has been shown feasible and interesting due to the high rate of use of ceramic materials in the building sector. However, it meets with some environmental issues and some prejudices on the part of users. This work sh...
متن کاملSludge granulation during anaerobic treatment of pre-hydrolysed domestic wastewater
The aim of this study was to examine sludge granulation during the anaerobic treatment of pre-hydrolysed municipal wastewater. The pretreated wastewater had a total chemical oxygen demand (CODt) of 432 ± 20 mg/l, a soluble COD (CODs) of 259 ± 8 mg/l, volatile fatty acids (VFA) of 101 ± 9 mg/l and suspended solids (SS) of 94 ± 12 mg/l. Prior to entering the digester, the influent was supplemente...
متن کاملusing treated domestic wastewater in concrete mixing
this document provides feasibility study of using treated domestic wastewater in concrete mixing. today, concrete is one of the most important construction materials. from first time that concert was used in construction materials, always the drinkable water used for concrete mixing water. domestic wastewater contains about 400 ppm of organic materials. after the treatment of wastewater, concen...
متن کاملThe Use of Clay-Polymer Nanocomposites in Wastewater Pretreatment
Some agricultural effluents are unsuitable for discharge into standard sewage-treatment plants: their pretreatment is necessary to avoid clogging of the filtering devices by colloidal matter. The colloidal stability of the effluents is mainly due to mutual repulsive forces that keep charged particles in suspension. Pretreatment processes are based on two separate stages: (a) neutralization of t...
متن کاملDataset of producing and curing concrete using domestic treated wastewater
We tested the setting time of cement, slump and compressive and tensile strength of 54 triplicate cubic samples and 9 cylindrical samples of concrete with and without a Super plasticizer admixture. We produced concrete samples made with drinking water and treated domestic wastewater containing 300, 400 kg/m(3) of cement before chlorination and then cured concrete samples made with drinking wate...
