Economic evaluation of submerged anaerobic hybrid membrane bioreactor operating at mesophilic temperature.

A laboratory-scale mesophilic submerged anaerobic hybrid membrane bioreactor (An-HMBR) was operated for 270 days for the treatment of high-strength synthetic wastewater at different hydraulic retention times (HRTs) (3 days, 2 days, 1 day, and 0.5 days). Chemical oxygen demand (COD) removal efficiency of 92% was obtained with methane yield rate of 0.

Anaerobic hybrid membrane bioreactor for treatment of synthetic leachate: Impact of organic loading rate and sludge fractions on membrane fouling.

In the present study, the treatment of synthetic landfill leachate was carried out using a lab-scale anaerobic hybrid membrane bioreactor (An-HMBR). The reactor was operated for 250 days at two days of hydraulic retention time (HRT). Average chemical oxygen demand (COD) removal efficiency was ≥ 88% at steady-state conditions at 100% raw leachate.

Performance enhancement and optimization of the anammox process with the addition of iron.

This study was conducted to evaluate the performance of anammox reaction on the addition of iron. Iron was added in the form of FeSO starting with 2 mg/L (phase I), 5 mg/L (phase II), 8 mg/L (phase III), 10 mg/L (phase IV), 30 mg/L (phase V) and 50 mg/L (phase VI) on the addition of Fe (II) in anammox reactor. The efficiency of ammonia removal increased up to 90% with 5 mg/L of Fe (II) addition as compared to 77% when no Fe (II) was added.

Performance evaluation and substrate removal kinetics in an up-flow anaerobic hybrid membrane bioreactor treating simulated high-strength wastewater.

The prime objective of the present study is to evaluate the performance of novel up-flow anaerobic hybrid membrane bioreactor (An-HMBR) treating high-strength wastewater (synthetic) using polyurethane foam as filter media. Treatment efficiency of the entire An-HMBR varied from 88-97% corresponding to 0.67-3.
