Abstract Microcoagulation has recently been considered as a promising pretreatment for an ultrafiltration (UF) process from numerous studies. To investigate the effects of microcoagulation on performance UF–reverse osmosis (RO) system treating wastewater with high and fluctuant salinity, different dosages coagulant (poly-aluminum chloride) were added prior to UF unit in pilot-scale UF–RO 10-wee...

Abstract The runoff of textile dye effluents into public water bodies is a major environmental and health problem. Color removal, in particular, has recently become substantial scientific interest, as revealed by the multitude related research reports. present study focused on measuring efficiency two marine algae, Ulva fasciata Pterocladia capillacea, bio-removal four synthetic dyes (RY2, RR19...

Salinisation of freshwater has been identified as a serious environmental issue in Australia and around the world. Protective concentrations (trigger values) for salinity can be used to manage salinity impacts, though require locally relevant salinity tolerance information. 72-h acute salinity tolerance values were determined for 102 macroinvertebrates collected from 11 locations in four biolog...

Anaerobic biological treatment of saline phenolic wastewater has some limitations such as slow adaptation, low biodegradability, and salinity-derived washout biomass, though this technology benefits in terms bioenergy recovery, simplicity operation, economic rationality. Therefore, we propose a packed-bed circular baffled reactor (PB-CBR) along with co-metabolism strategy for phenol adaptation ...

Oxygen-limited autotrophic nitrification/denitrification (OLAND) is a one-stage combination of partial nitritation and anammox, which can have a challenging process start-up. In this study, start-up strategies were tested for sequencing batch reactors (SBR), varying hydraulic parameters, i.e. volumetric exchange ratio (VER) and feeding regime, and salinity. Two sequential tests with two paralle...

Observations from 35 tropical moorings are used to characterize the diurnal cycle in salinity at 1 m depth. The amplitude of diurnal salinity anomalies is up to 0.01 psu and more typically 0.005 psu. Diurnal variations in precipitation and vertical entrainment appear to be the dominant drivers of diurnal salinity variability, with evaporation also contributing. Areas where these processes are s...
