Summary form only given. Aqueous environments are susceptible to contamination by bacteria, protozoa and viruses, which are the root cause of various illnesses. These contaminations are usually treated by chemical methods. Recently, attempts have been made to inactivate bacteria in water with non-thermal plasmas using various approaches, e.g., a pulsed streamer discharge plasma or a gliding arc discharge...
The effect of pH in the range of 3.0–11.0 on anaerobic fermentation of primary sludge (PS) was investigated at room temperature. The experimental results showed that the concentrations of soluble chemical oxygen demands (SCOD), soluble protein and carbohydrate and short-chain fatty acids (SCFAs) under alkaline conditions were significantly higher than those under other pHs. At fermentation time of...
This paper investigated the influence of pH on short-chain fatty acids (SCFAs) production and constituents with anaerobic fermentation of primary sludge from a Chinese wastewater treatment plant (WWTP). Controlled and uncontrolled pH experiments were conducted in ten completely mixed bench-scale reactors. Results showed that pH significantly influenced on the SCFAs yields and constituents from primary...
