Sewage dom absorption

WebResearch on high-rate anaerobic sewage treatment started in the early 1980s with the 64 m3 UASB pilot plant in Cali, Colombia and various other initiatives in Brazil. Hereafter the technology was adapted to full-scale conditions and slowly introduced in the market. This chapter describes the anaerobic treatment process for domestic Web350 (30%), indicating that C1 and C2 were the dominant constituents of sewage DOM. As a result, long-wavelength-excited C4 and C5 became the dominant humic-like components and the DOM molecular size inferred from the variation of spectral slope S (300–650 nm) and specific absorption (a 280/DOC) increased.
