Green Technologies for Wastewater Treatment: Energy Recovery by Giovanni De Feo, Sabino De Gisi (auth.), Giusy Lofrano

By Giovanni De Feo, Sabino De Gisi (auth.), Giusy Lofrano (eds.)

In order to examine the demanding situations posed by way of the hunt for sustainability, Green applied sciences for Wastewater therapy: power restoration and rising Compounds Removal evaluates water administration including power use. The powerful results that the discharge of rising toxins equivalent to endocrine disruptors (EDCs), prescription drugs and private care items (PPCPs) have in wastewater reuse functions are tested, in addition to the necessity to optimize the power intake in wastewater remedy.

More particularly, this quantity specializes in:
- featuring the benefits associated with the applying of chemically assisted basic sedimentation (CAPS) that allows power optimization of wastewater therapy vegetation and issues to the opportunity of wastewater as a potential resource;

- Discussing the analytical difficulties regarding the analytical detection of rising pollution and in their transformation products;

- evaluating the potency of MBR vegetation for removal hint pollution with traditional systems;

- comparing the appliance of rainy Oxidation (WO) for the remedy of aqueous effluents to take away hint pollutants;

- Reviewing the applying of Photo-Fenton strategy and complementary therapy structures (H2O2/UV-C and Fenton’s reagent) for the degradation of 2 business pollutant different types with major endocrine disrupting houses: alkyl phenols (nonyl and octyl phenols) and bisphenol A.

Green applied sciences for Wastewater therapy: strength restoration and rising Compounds Removal may be of serious curiosity to scholars, technicians, and teachers alike who're attracted to comparing and choosing the applied sciences that bring about greater and extra sustainable therapy of those large periods of pollutants.

It is well known that the use of chemical–physical treatment allows an increase of primary sludge production [10, 21]. 3%) was registered in the study. 1%. Finally, the total sludge production (primary and secondary sludge) in the ‘‘Assisted Set-ups’’ was slightly less than the corresponding production for the ‘‘Natural Set-up’’, as shown in Fig. 5. 3 Biological Gas Production and Consumption of Energy for the Aeration and Nitrification Phases The consumption of energy for the final biological treatment as well as the results of the biological gas production from the anaerobic sludge digestion for the three studied set-ups are shown in Fig.

Management system based on a separation of primary and secondary sludge treatment and disposal. 9% was estimated. 4 Concluding Remarks The following general outcomes on the CAPS as a green chemistry option can be stated: • the economic analysis developed with a paradigmatic case study emphasised the applicability of the CAPS process for the treatment of urban wastewater, particularly emphasising the choice of a sludge management system based on a separation of primary and secondary sludge treatment and disposal • since CAPS does not require further structural interventions, it is particularly suitable as a technique for the upgrading of urban WWTP, avoiding the construction of new units or even new plants (so saving investment costs and territory portions) • application of CAPS may be useful in numerous situations (in a WWTP where the activated sludge process is designed with a high load; in a WWTP subject to a strong seasonal variation; in a WWTP for the treatment of urban wastewater that could be affected by management problems due to the presence of industrial wastewater) 1 Chemically Assisted Primary Sedimentation 17 • principal CAPS ‘‘green’’ effects relate to the increase in the production of primary sludge, lowering of the food/microorganisms ratio (F/M), reduction of the production of secondary biological sludge, reduction of the energy costs due to a lower F/M and, finally, increase in the production of biological gas from the anaerobic digestion phase.
