background: the disposal the wastewater sugar extraction to the rivers and environment cause contamination and is considered as a threat to the marine life and the environment. thus, treatment of the wastewater is necessary. investigating the reduction of the pollution load of cane industry with anaerobic sequencing batch biofilm reactor (asbbr) in the laboratory scale is the purpose of this st...

Dairy wastewater is enriched in organic matter (about 45-72 g/l, COD) and also contains biodegradable carbohydrates. A three-stage system, NRBC was fabricated as a bench scale unit for lab experiments, to remove organic carbon from the whey. The fabricated NRBC had several advantages, such as quick start-up, high biomass concentration and was additionally able to handle high organic loading rat...

A two-phase anaerobic biodigestor was employed in order to analyze methane production with different manipueira organic loading rates. The acidogenic phase was carried out in a batch process whereas the methanogenic in an up-flow anaerobic fixed bed reactor with continuous feeding. The organic loading rates varied from 0.33 up to 8.48g of Chemical Demand Oxygen (COD)/L.day. The highest content ...

introduction water scarcity has led to the search for alternative water resources. one solution is the recycling of wastewater for irrigation. wastewater treatment is often based on biological systems such as activated sludge or other engineered units in urban areas. in rural areas, low-cost, environmentally-friendly alternative treatments such as constructed wetlands (cw), are more common. cws...
