“…The filtration flux was kept at 50 liters per m 2 of membrane area per hour (LMH) via a peristaltic pump (Masterflex HV-07575-10; Cole Parmer, Vernon Hills, IL, USA), operated at an mode of 8 min on and 2 min off. Activated sludge sampled from a local wastewater treatment plant was inoculated according to Eckenfelder (1966) for two weeks. During both inoculation and MBR operation at ambient temperature, the reactor was fed with synthetic wastewater containing dextrose as the sole carbon source (COD of 480 mg/L) and the following composition (Eckenfelder, 1966): K 2 HPO 4 , 1.28 g/L; KH 2 PO 4 , 0.64 g/L; NH 4 Cl, 0.48 g/L; MgSO 4 ·7H 2 O, 0.6 g/L; FeSO 4 ·7H 2 O, 0.02 g/L; ZnSO 4 ·7H 2 O, 0.02 g/L; MnSO 4 ·7H 2 O, 0.02 g/L; and CaCl 2 , 0.08 g/L.…”

“…Greywater treatment effectiveness was tested using vapor compression distillation23 and evaporator 24. The treatment of greywater has also been investigated based on reedbed technology using the following plant species: Coix lacryma jobi ,25 Triglochin huegelli ,26 Alnus, Salix spp., Aegopodium podagraria, Filipendula ulmaria, Cirsium oleraceum, Phragmites communis and Typha latifolia 27. Garland et al (2000)28 evaluated the treatment of greywater using hydroponic systems based on phyto‐toxicity, surfactant degradation and bacterial dynamics.…”
