This paper determined cations and anions concentrations, Total Kjeldahl Nitrogen (TKN), and heavy metals content in sewage sludge collected from the drying beds of wastewater treatment plant in Gaza. The aim was to test the possibility of using this sewage sludge as an alternative source of mineral fertilizers. Many instruments were used in this work: flame photometry (K, Na), EDTA titration (Ca, Mg), the turbidity method ( )

“…Both sulfate and sulfite are known to act as electron sinks in anaerobic digestion and compete with methanogens for hydrogen. Jing et al (2013) studied the anaerobic performance when treating sulfate-rich wastewater and found that at a concentration of 3000 mg/L of sulfate and high organic loading rates of 6-18 gCOD/L day À1 sulfate removals remained between 28 and 42% and COD removals were above 80%. In this study, initial sulfate concentrations for both R1 and R2 was 67 mg SO 4 /L and for R3 was 141 mg SO 4 /L.…”

The methane potential and biodegradability of different ratios of acetate and lignin-rich effluents from a neutral sulfite semi-chemical (NSSC) pulp mill were investigated. Results showed ultimate methane yields up to 333±5mLCH4/gCOD when only acetate-rich substrate was added and subsequently lower methane potentials of 192±4mLCH4/gCOD when the lignin fraction was increased. The presence of lignin showed a linear decay in methane production, resulting in a 41% decrease in methane when the lignin-rich feed had a 30% increase. A negative linear correlation between lignin content and biodegradability was also observed. Furthermore, the effect of hydrotalcite (HT) addition was evaluated and showed increase in methane potential of up to 8%, a faster production rate and higher soluble lignin removal (7-12% higher). Chemical oxygen demand (COD) removal efficiencies between 64 and 83% were obtained for all samples.

“…In anaerobic treatment processes, SRB and methane-producing archaea (MPA) always compete for a carbon source (Jing et al 2013). In sulfate-rich wastewater digestion, SRB often outcompetes MPA, and produces corrosive and poisonous sulfide.…”

In this chapter, the transformations and the response of ammonia and hydrogen sulfide in anaerobic systems are summarized and subdivided into several topics. Chemical quantitative analyses including fermentation stoichiometry, dissociation equilibrium, the gas-liquid equilibrium of NH3 and H2S and the pH buffer system in anaerobic processes are introduced. The positive and negative roles of ammonia in anaerobic digestion are discussed in detail based on recent research. The formation and harmful corrosion of hydrogen sulfide are elucidated, along with the technologies for sulfate-rich wastewater treatment and hydrogen sulfide removal from biogas.
