Possible cause of excess sludge reduction in an oxic-settling-anaerobic activated sludge process (OSA process)
TL;DR: This paper systematically evaluates the following possible scenarios that may explain the reduction of excess sludge in the OSA process: energy uncoupling, domination of slow growers, soluble microbial products (SMPs) effect and sludge decay in the sludge holding tank under a low oxidation-reduction potential (ORP) condition.
Journal ArticleDOI
ATR-FTIR and XPS study on the structure of complexes formed upon the adsorption of simple organic acids on aluminum hydroxide.
TL;DR: The attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectra revealed that the ligands benzoate and salicylate do coordinate directly with the surface of hydrous aluminum hydroxide, thereby forming inner-sphere surface complexes that form monodentate and bridging complexes when the initial pH is acidic or neutral.
Journal ArticleDOI
Biological sulfur oxidation in wastewater treatment: A review of emerging opportunities.
Sen Lin,Hamish R. Mackey,Tianwei Hao,Tianwei Hao,Gang Guo,Mark C.M. van Loosdrecht,Guanghao Chen +6 more
TL;DR: New merits of biological sulfide oxidation from a traditional environmental management perspective as well as a waste to resource perspective are presented along with their potential applications.
Journal ArticleDOI
A pilot study for wastewater reclamation and reuse with MBR/RO and MF/RO systems
TL;DR: In this paper, a pilot study was conducted to evaluate the quality of the effluent of an enhanced tertiary treatment process consisting of MBR/RO or MF/RO units and explore the feasibility of reclamation of treated effluent for potable and non-potable reuse applications.
Journal ArticleDOI
Feasibility of using a chlorination step to reduce excess sludge in activated sludge process.
TL;DR: This paper proposes to use chlorination to replace ozonation in excess sludge minimization in the light of operational cost and investigates the feasibility of this low cost approach on sludge reduction rate, formation of trihalomethanes, sludge settleability, and effluent quality.
