The effect of vermifiltration height and wet:dry time ratio on nutrient removal performance and biological features, and their influence on nutrient removal efficiencies

Ecological Engineering, 2014
Abstract We investigated the effects of vermifiltration (VF) height and the wet:dry time (WD) ratio on nutrient removal from synthetic domestic wastewater, earthworm population characteristics, and microbial numbers in the substrate. We also evaluated the key factors influencing nutrient removal.

The effect of primary sedimentation on full-scale WWTP nutrient removal performance

Water Research, 2010
Traditionally, the performance of full-scale wastewater treatment plants (WWTPs) is measured based on influent and/or effluent and waste sludge flows and concentrations. Full-scale WWTP data typically have a high variance which often contains (large) measurement errors.

Long-term performance of nutrient removal in an integrated constructed wetland

Science of The Total Environment, 2021
Constructed wetlands (CWs) have been regarded as efficient technologies for both wastewater treatment and reuse of water resources. Most studies on CW treatment efficiency are limited to a short-term perspective, and there are still many unknowns about the long-term performance of CWs. Here we evaluated the performance of an integrated CW that has been

A modified UCT method for biological nutrient removal: Configuration and performance

Chemosphere, 2008
A pilot-scale prototype activated sludge system is presented, which combines both, the idea of University of Cape Town (UCT) concept and the step denitrification cascade for removal of carbon, nitrogen and phosphorus. The experimental set-up consists of an anaerobic selector and stepwise feeding in subsequent three identical pairs of anoxic and oxic ...

Performance of a Submerged Membrane Bioreactor System for Biological Nutrient Removal

Water Environment Research, 2006
A pilot submerged membrane bioreactor coupled with biological nutrient removal was used to treat the primary effluent at a municipal wastewater treatment plant. Long‐term experiments were conducted by varying hydraulic retention time from 6 to 8 hours and solids retention time from 20 to 50 days, respectively. The performance was assessed by monitoring

Biological nutrients removal performance under starvation stress: Efficacy deterioration and recovery

Bioresource Technology, 2022
Biological nutrients removal performance affected by starvation stress was investigated via the addition of pre-anoxic stage to SBR. COD removal efficiency maintained at around 90% regardless of the starvation stress. Starvation stress presented significant impact on nitrogen and phosphorus removal, with noticeable reduction of TN removal and ...

Statistical Analysis of the Performance of a Biological Nutrient‐Removal Plant

Water and Environment Journal, 2000
AbstractThames Water operated a demonstration‐scale biological nutrient‐removal plant for two years to investigate the feasibility of retrofitting it into existing activated‐sludge plants. The plant was operated with and without the addition of short‐chain fatty acids to the anaerobic zone.

Optimization of nutrient removal performance of magnesia-containing constructed wetlands: a microcosm study

Environmental Science and Pollution Research, 2021
Recently, magnesia has drawn much attention for enhancing phosphorus (P) removal of constructed wetlands. However, the poor nitrogen (N) removal efficiency of magnesia-containing constructed wetlands (Mg-CWs) inherently caused by magnesia impedes its application. In this study, peat and intermittent aeration were applied to enhance N removal in a Mg-CW,
