The current paper assesses the reliability coefficients of fifty six low-cost, full-scale wastewater treatment plants, including nine different treatment technologies for wastewater reuse in aquaculture and agriculture in northeast Brazil. This was carried out with the aim to evaluate alternatives for sustainable wastewater reuse in communities experiencing water scarcity. The technologies eval...

The topical antiseptic agent triclocarban (TCC) is a common additive in many antimicrobial household consumables, including soaps and other personal care products. Long-term usage of the mass-produced compound and a lack of understanding of its fate during sewage treatment motivated the present mass balance analysis conducted at a typical U.S. activated sludge wastewater treatment plant featuri...

Prediction for self-weight consolidation of dredged sludge is important its reuse in civil engineering applications. In this work, considering the special nonlinear relationships e – k and ?? sludge, Gibson’s large strain equation was modified to simulate process sludge. Using finite difference method (FDM), influences four main parameters, including initial height, void ratio, ratio at liquid ...

Optimised Ammonia Sanitisation of Sewage Sludge Franziska Häfner The usage of sewage sludge as an organic fertiliser offers a way to recycle nutrients and organic matter for a sustainable agriculture. Sewage sludge is rich in plant nutrient like nitrogen, phosphorus, potassium and micronutrients. Concerning the depletion of phosphorus resources, the reuse of sewage ...

Alum salts are commonly used as coagulants in the purification of surface water for potable supplies. The resultant waste alumina-rich sludge is currently landfilled UK. This study aimed to valorise by using heat-treated alum an additive cement. was calcined at 475–1100 °C and then characterized correlate physical mineralogical changes with cementitious activity engineering performance. 825 tra...

It is widely known that many regions in the world have scarce water resources. In these areas the groundwater aquifers are also found to be in a critical condition as a result of overexploitation. That is why, in such regions, the reuse of wastewater is a common practice and the competent authorities undertake multiple courses of action to encourage its reuse. Legislation implementing the recla...
