Piggery effluent is one of the most highly produced wastewaters throughout world, containing high levels inorganic nutrient species. In this study, a microalga Scenedesmus obliquus YSW-14 (S. obliquus) was employed not only for removal from piggery wastewater but also lipid accumulation in algal biomass as feedstock biofuel production. The diluted up to fivefold with synthetic media reduce toxicity (in)organic components, which resulted improved microalgal growth, removal, and productivity....
A novel adsorbent was developed impregnating graphite nanocarbon (GNC) into alginate beads (AB) for efficient cobalt (Co(II)) removal from an aqueous solution. Physicochemical and spectroscopic properties of nanocarbon–impregnated (ABGNC) were characterized compared with those AB. Co(II) adsorption on ABGNC quantitatively evaluated by determining kinetics thermodynamics parameters. The capacity onto highest at neutral pH condition. Increasing the temperature 288 to 318 K resulted in a...
Based on our earlier diagnosis that hydrophobic and hydrophilic (HPO/HPI) acids are the primary cause of short-term fouling in ultrafiltration secondary effluent, HPO/HPI were extracted subsequently characterized comparison with commercial organic materials. isolated from effluent contained significantly fewer complex mixtures than humic substances have been implicated as dominant foulants filtration surface water using porous membranes. The physicochemical spectroscopic characterization...
Two different quaternary amine polymers were examined as primary coagulants for the removal of natural organic matter (NOM) and concurrent production flocs favorable downstream membrane separation. The issue explored was relationship between various coagulation conditions on floc characteristics subsequent performance microfiltration when filtering coagulated NOM. size distribution morphological properties formed through NOM characterized effects polymer type dose these also examined....
The feasibility of using magnetic ion exchange (MIEX) treatment, in-line alum coagulation, and low-pressure membrane filtration was investigated for the simultaneous removal total phosphorus (TP) effluent organic matter (EfOM) from biologically treated wastewater. focus also placed on minimizing fouling polyvinylidene fluoride polyethersulfone membranes, which are most commonly used membranes in new retrofit wastewater treatment plants. MIEX alone effective EfOM, plus a small dose very...
Low-pressure membrane filtration is increasingly used for tertiary treatment of wastewater effluent organic matter (EfOM), mainly comprising base/neutral compounds. In-line coagulation with underdosing, charge neutralization, and sweep floc conditions prior to ultrafiltration (UF) was studied determine removals the EfOM components consequent reduction fouling using polyethersulfone membranes. Coagulation UF substantially reduced all while removing from 7 38% acids. From 16% base/neutrals...
