UASB-Reaktor • BiogasWorld. UASB-Reaktor. UASB or EGSB Reactors use gas/liquid/solids (GLS) separators and overflow weirs in the reactor top section to separate biogas and biomass and settle and return biomass to the reactor sludge bed. IB-MR developed a novel type of GLS separator with special emphasis on simple design with good hydraulic
The UASB reactor has the potential to produce higher quality effluent than Septic Tanks and can do so in a smaller reactor volume. Although it is a well-established process for large-scale industrial wastewater treatment and high organic loading rates up to 10 kg BOD/m3/d its application to domestic sewage is

Two UASB reactors were set up and operated in parallel to evaluate the treatment efficiency of petroleum refinery wastewater. In this study four organic volumetric loading rates were applied (i.e. 0.58 0.89 1.21 and 2.34 kg/m3·d) two loads to each reactor.
· The UASB reactor as the methanogenic stage was a 1.3-L total volume thermostated glass vessel with a working volume of 1 L. The produced biogas was collected from the top of both reactors into gas-tight aluminum bags (Fig. 1). Before starting the experiment the UASB reactors were inoculated with 200 mL of granular sludge and 800 mL of

· The two reactors were constructed in transparent acrylic sheet. The dimension of the acidogenic reactor was 18 cm width 18 cm breadth and 50 cm height. In the present study the better performance of the reactors than the reactors reported by other investigators can be attributed to two reasons. One definite reason is the phase separation.

The UASB reactor has the potential to produce higher quality effluent than Septic Tanks and can do so in a smaller reactor volume. Although it is a well-established process for large-scale industrial wastewater treatment and high organic loading rates up to 15 kg BOD/m3/d its application to industrial effluents and domestic sewage is still relatively new.
· The UASB reactor can be designed as circular or rectangular. Modular design can be preferred when the volume of reactor exceeds about 400 m3. It is necessary to select proper range of operating parameters for design such as OLR SLR superficial liquid upflow velocity (referred as liquid upflow velocity) and HRT.
The upflow anaerobic sludge blanket reactor (UASB) is a single tank process in an anaerobic centralised or decentralised industrial wastewater or blackwater treatment system achieving high removal of organic pollutants. Wastewater enters the reactor
