... the optimal concentration of raw leachate in synthetic wastewater was determined (5% v/v–40% v/v). At this stage, UASB reactor was operated at hydraulic retention time (HRT) of 7 days and organic loading rate (OLR) of 0.6 kg COD × m−3 d−1. While the optimal concentration of raw leachate i ...

Removal of bacterial and viral indicators in vertical flow constructed wetlands and intermittent sand filters
... wetlands (VFCWs) and four intermittent sand filters (ISFs) that treat pond effluent. Tracer tests (NaCl) were performed to estimate the hydraulic retention time (HRT) of the filters. The contribution of Phragmites australis to the removal of the faecal indicators was examined. The effect o ...

Influence of hydraulic retention time on the operation of a submerged membrane sequencing batch reactor (SM-SBR) for the treatment of greywater
This study describes the experience received in operating an SM-SBR under different hydraulic retention times for the treatment of synthetic greywater. The pilot scale SM-SBR with a working volume of VR = 500 L is operated with hydraulic ...
