Seawater contains high concentrations of sparingly soluble salts which can cause scaling the membrane surface, in turn limit productivity and water recovery potential seawater reverse osmosis (SWRO). Nanofiltration (NF) pre-treatment prevent via preferential removal scale-forming ions. Several studies have shown that rejection ions vary considerably depending on membrane. The main objective this study was to test a number commercially available NF membranes with synthetic order compare their...
A number of nano-filtration membranes exhibit quite high rejections sulfates (98–99%) accompanied by moderate (sometimes as low 10–20% and even less) chlorides from highly concentrated electrolyte solutions like sea water or various brines. In this communication, it is shown that phenomenon can hardly be explained within the scope commonly accepted model where barrier layer considered a nano-porous medium, and, accordingly, there considerable convective coupling between transfers solutes...
ABSTRACT Seawater contains high concentrations of sparingly soluble salts which can cause scaling membrane surface, limiting the productivity and water recovery seawater reverse osmosis (SWRO). Nanofiltration (NF) pretreatment seawater, prevents via preferential removal scale-forming ions. Several studies have shown that rejection ions is not same for various membranes. In a previous study, selection best NF membranes prevention in SWRO was developed using synthetic seawater. The main...
A prototype pilot plant testing for a novel complete treatment strategy landfill leachate aimed to decrease its environmental impact was studied. Pre-treatment of performed by means membrane bioreactor (MBR) decreasing inorganic carbon concentration 92 ± 8% and achieving N removals 85%. Suspended solids removal in the MBR >99.9% conditioned next step. Spiral-would reverse osmosis (RO) regenerated membranes were used treat effluent. This RO unit achieved global recovery 84% along with...
Three upflow anaerobic sludge blanket (UASB) pilot scale reactors with different configurations and inocula: flocculent biomass (F-UASB), membrane solids separation (F-AnMBR) granular (G-AnMBR) were operated to compare start-up, hydrolysis effluent quality. The parallel operation of UASBs these at low temperatures (9.7 ± 2.4°C) the COD content (sCOD 54.1 10.3 mg/L pCOD 84.1 48.5 mg/L), was novel not previously reported. A quick start-up observed for three could be attributed previous...
Abstract The sorption kinetics of antimony(V) on synthetic goethite is very fast compared to the other metals (e.g. arsenic and selenium) depends temperature, with an activation energy 49±9 kJ · mol−1 in temperature range 15–35°C. Sorption isotherms have been developed at different temperatures ionic strength values. results modelled using a Langmuir isotherm there not considerable influence neither studied (15°C–35°C), nor (between 0.001 0.01 mol dm−3). high pH values lower than 8, more...
Spatial distributions of fifteen trace elements (As, Be, Cd, Co, Cr, Cu, Mo, Ni, Pb, Sb, Sn, Tl, U, V, and Zn) potentially harmful for the human health ecosystem have been studied in soils Catalonia. Geographic Information Systems were used together with cartographic information available sampling design. Descriptive statistics, box-plots, cumulative distribution figures to assess differences element concentrations among soil uses. A clear enrichment Pb Sn (mean 24.3 3.31 mg · kg−1 d.w.,...
Abstract A laboratory‐scale pilot plant of moving bed biofilm reactor coupled with membrane bioreactor (MBBR‐MBR) was studied regard to wastewater treatment in the textile industry, and reuse feasibility treated water investigated. The comprised two connected parts: an aerobic tank filled carriers a submerged tank. MBBR‐MBR system reduced hydraulic retention time 1 day, which is very promising compared conventional biological industry. removal efficiency chemical oxygen demand reached 93%,...
