Improving Biogasfermentation of Sludge and Cosubstratesby Combining Acidification with Disintegration Systems

UncategorizedResearch Article

semi-scale acidification batch reactor (700 litres) was installed at the domestic wastewater treatment plant Hof (Germany) and feed with thickened sludge and treated with electroporation and hydrodynamic induced cavitationwith exposure times up to 6 hours. Inoculation from the large-scale sludge digester improved acidification significantly.Investigations were carried out…

The Origin of Submerged-Soil-Based Rice Cultivationwith an Emphasis on Archeological Evidences

UncategorizedResearch Article

Rice cultivation has long been considered to have originated from seeding of annual types of wild rice somewhere in subtropics, tropics or in the Yangtze River basin. That idea, however, contains a fatal weak point, when we consider the tremendous difficulty for primitive human to seed any cereal crop in the warm and humid climate, ….  Read More

Phenol and Polyphenol Removals in Olive Mill Effluent with Nano-Zno-Magnetite Composite via Photo Catalysis

UncategorizedResearch Article

Olive mill wastewater (OMW) contains high concentration of organic matter, acidic pH values, suspended solids and high content of phenols and polyphenols which are toxic substances. The aim of this study is the removals of total phenol and two polyphenos namely tyro sol and hydroxytyrosol in the OMW by Nano-ZnO-Magnetite composite via photo catalytic degradation…

Alligator Grass (Alternanthera Philoxeroides), A Nuisance Aquatic Plant but a Potential Feedstock for Biofuels Production

UncategorizedReview Article

Alligator grass (Alternanthera philoxeroides) is considered a nuisance aquatic plant. This biomass however has prolific growth and hence a potential feedstock for biofuels production. This biomass resource is considered an invasive species but will not compete with agricultural food or feed production. It can generate more than 7.85 tonnes of biomass per hectare (dry) and ….  Read More

Anaerobic Removals of Polybrominated Diphenylether (PBDE), Hexabromocyclododecane (HBCD) and Tetrabromobisphenol A (TBBPA) in Hospital Wastewaters

UncategorizedResearch Article

The this study, the anaerobic degradation and sorption of 3 polybrominated micropollutants (polybrominated diphenylethers (PBDE), hexabromocyclododecane (HBCD) and tetrabromobi-sphenol A (TBBPA) was studied in UASB reactor at increasing SRTs. The optimum SRT for maxi-mum total removals of TBBPA, HBCD and PBDE were 93%, 96% and 97% at a SRT of 35 days at 37oC…

Adsorption of Dyes from Water on to Bamboo-Based Activated Carbon – Error Analysis Method for Accurate Isotherm Parameter Determination

UncategorizedResearch Article

The adsorption of Reactive Black 5 dye from aqueous solution been studied using four types of adsorbents, namely BACX6 (Bamboo Activated Carbon), BACX2, Filtrasorb F400 and bone char.It is important to determine the most accurate capacity parameters from isotherm studies in order determine the size of an adsorption water treatment process…
