Sewage is a climate linked science in that C and N containing compounds before their final sequestration stage are the most potential GHGs like CH4 and N2O. Therefore, their sequestration and or fixation is THE AIM of sewage treatment. Besides public health the sewage management is about climate health. All organic compounds in Sewage Treatment Plants (STPs), must be addressed at molecular level and not in terms of tonnage and billions of dollars invested on infrastructure and technology. Rivers are the anaerobic digesters of this planet. The process begins at zero order streams and urbanism has destroyed them long ago. Above all sustainable cities are a myth. Evaluation of conventional STPs reveal that it is a living cell membrane with a sandwich structure and gas diffusion through it goes beyond Boyle’s law. Aeration and dilution for pumping convenience is a flawed path. Argument is that if atmospheric oxygen can be taken by a microbe in the aeration process, why do plant cells require Nitrifiers to take atmospheric nitrogen? Although CO2 concentration is 0.04 % against nitrogen (79%). Henry’s law if applicable should not permit CO2 uptake by plants. Study reveals that Sewage degradation is an energy releasing path, any external input interferes with the process. Sewage treatment or transfer? Conventional STPs emphasize only gravitational pull. Also environmental quality is compromised as the aerosol from the treatment plant is carried in the atmosphere. STPs are throwing in the air Nitrous oxide and aerosol. Further this paper explains the Molecular nature of the sludge and conversion of Fecal acetate to Sludge acetate in ASP, achieving nothing in terms of wastewater treatment. Propagating the science of sewage and nature based solution for the wastewater treatment is the goal of this study.
