The goal of the present research work was to assess the management of sewage sludge (SS) by composting using fermented water hyacinth (WHferm) as an amendment. The water hyacinth was fermented, and a higher production of volatile fatty acids (VFAs) (782.67 mg L−1) and soluble organic carbon (CSOL) (4788.34 mg L−1) was obtained using a particle size of 7 mm compared to 50 mm. For composting, four treatments (10 kg fresh weight each) were evaluated: treatment A (100 % SS + 0 % WHferm), treatment… Expand

Performance of co-composting sewage sludge and organic fraction of municipal solid waste at different proportions.
Results show that higher SS proportion could rapidly initialize the co-composting process; while increasing OFMSW percentage enhanced organic content for biodegradation, thus prolonging the thermophilic period and increasing the humification degree during co- Composting. Expand

Green waste (GW) composting is of increasing importance to the waste management industry in addition being a useful agricultural product that is rich in nutrient and organic matter (OM). TheExpand
Degradation of biochemical fractions in different temperature of food waste bioevaporation and their contribution to biogenerated heat
Abstract Bioevaporation is a treatment for highly concentrated organic wastewater that uses biogenerated heat from organic matter degradation to remove water from wastewater itself. The degradationExpand
Study on Dissolution Characteristics of Excess Sludge by Low-Temperature Thermal Hydrolysis and Acid Production by Fermentation
It is proved that low-temperature thermal pretreatment promotes the process of acid-producing fermentation and has no effect on the type of fermentation and the optimal condition for hydrolytic dissolution and acid production under low- temperatures is 80 °C. Expand

Effect of C/N on composting of pig manure with sawdust.
Co-composting of pig manure with sawdust at a low initial C/N would require a composting longer than 63 days, and, the high salinity due to the large amount of pork manure would pose a potential inhibition on plant growth. Expand

Changes in chemical and biological parameters during co-composting of anaerobically digested sewage sludges with lignocellulosic material
A pilot experiment of composting of anaerobically digested sewage sludges deriving from the production of biogas in a wastewater treatment plant indicated that the process produced a compost suitable for agricultural applications as far as the physicochemical properties were concerned. Expand
Assessment of a potential agricultural application of Bangkok-digested sewage sludge and finished compost products
It is proven that the quality of the sludge mixed with grass clippings at a ratio of 6:1 volume/volume after having passed a windrow composting process for 8 weeks can be classified as class A biosolids as the levels of remaining fecal coliforms were < 3 most probable number g−1 dry solid and all human parasites were destroyed.

Monitoring and optimizing the co-composting of dewatered sludge: a mixture experimental design approach.
According to empirical modeling, mixtures of sludge and food waste mixtures at 1:1 ratio (ww, wet weight) maximize degradability and structural amendments should be maintained below 30% to reach thermophilic temperatures. Expand
Optimization of dilute acid pretreatment of water hyacinth biomass for enzymatic hydrolysis and ethanol production
The present study was conducted for the optimization of pretreatment process that was used for enzymatic hydrolysis of lignocellulosic biomass, which is a renewable resource for the production of bioethanol with decentralized availability and the order of catalytic effectiveness was found to be phosphoric acid > maleic acid > sulfuric acid.
