a study was performed in hybrid up flow anaerobic sludge blanket (huasb) and anaerobic filter (af) reactors to compare the start-up time and optimum hrt required for the treatment of poultry slaughterhouse wastewater under similar loading conditions. initially, the reactors were started at an olr of 0.77 kg cod/m3.d and hrt of 36 h. loading rates were increased by reducing hrt 24, 16, 12, 10 an...

In India, Pulp & paper industries have been large uses of portable water and consequently large generator of waste water. Anaerobic treatment of paper processing waste water has a distinct advantage of recovery of inherent energy in the form of methane gas with much less sludge production. A hybrid reactor that capitalizes on the positive features of anaerobic filter(AF) and up-flow anaerobic s...

This paper presents a review and findings of the Hybrid Upflow Anaerobic Sludge Blanket (HUASB) technologies, deploying lab scale reactors for treatment domestic industrialwastewater. The major controlling parameters HUASB such as inert media used, pH, temperature, upflow velocity, organic loading, hydraulic residence time along with startup granulation are highlighted its efficient performance...

Wastewater from the food industry that contains a high organic load, such as wastewater tofu manufacturing process, requires an appropriate and efficient treatment system to reduce pollutants before being discharged into water bodies. The most suitable for loads is anaerobic system. process of suspended media, attached or combination thereof hybrid. This study uses Hybrid Upflow Anaerobic Sludg...

An experimental study of anaerobic treatment was performed by hybrid upflow anaerobic sludge blanket (HUASB) reactor to treat produced water (PW) of an onshore crude oil terminal (COD: 1597 mg/L, NH3-N: 14.7 mg/L, phenol: 13.8 mg/L, BOD5: 862 mg/L, sodium: 6240 mg/L and chloride 9530 mg/L). The produced water with high salinity and other toxic substances will inhibit the methanogens performance...
