Microwave-assisted oxidative digestion of lignin with hydrogen peroxide for TOC and color removal
Dilute lignin solution was successfully digested into colorless and clarified liquor under microwave-assisted oxidative digestion with hydrogen peroxide. High dosage of hydrogen peroxide is needed to effectively digest lignin, but excessive hydrogen peroxide may lead to recondensation of formed fragments in digested lignin. Microwave irradiation greatly facilitates the oxidative digestion of ...

Effect of trace metals on halophilic and mixed cultures in anaerobic treatment
Abstract: Trace metals are known to stimulate the activity of anaerobic methanogenic bacteria involved in the degradation of organic matter. The objective of this research was to investigate the effect of three trace metals, iron, nickel and cobalt on the activity of halophilic methanogens, digester sludge and a mixed culture of halophilic bacteria and digester sludge, at various salt ...

The influence of temperature and SRT on high-solid digestion of municipal sewage sludge
The influence of temperature and solids retention time (SRT) on high-solid digestion of municipal sewage sludge was investigated in laboratory-scale reactors. Digestion with high-solid concentration reduces the required digestion volume and is advantageous for urban areas. The experimental conditions comprised total suspended solids (TSS) in digested sludge between 4.0 and 4.6%, temperatures ...

Extracellular polymeric substances and dewaterability of waste activated sludge during anaerobic digestion
Anaerobic digestion of waste activated sludge was conducted to gain insight into the mechanisms underlying change in sludge dewaterability during its anaerobic digestion. Unexpectedly, the results indicated that sludge dewatering properties measured by capillary suction time only deteriorated after 10 days of anaerobic digestion, after which dewaterability recovered and remained stable. The ...

High dry solids digestion
Abstract Digestion of sewage sludge normally takes place at pH values between 7,0 and 7,5. Control methods of the process stability are based on practical experience such as the ratio of volatile fatty acids (VFA) and total alkalinity (TA). Thermal sludge disintegration for an enhanced digestion process allows a digester feed with higher dry solids concentrations. This is due to an opening of ...
