An innovative osmotic membrane bioreactor (OMBR) is currently under development for the reclamation of wastewater, which combines activated sludge treatment and forward osmosis (FO) separation with a RO post-treatment. The research focus FO fouling performance using different investigated both at laboratory scale (membrane area 112 cm2) on-site bench (flat sheet 0.1m2). on laboratory-scale (i) increased temperature due to decrease in viscosity (ii) was independent type sludge. Draw solution...
The integration of temperature sensors directly onto photonic platforms facilitates the thermal management advanced integrated circuits. This paper presents monolithic on indium-phosphide-based technology. Two distinct were developed using p-i-n diode junctions with different waveguide core layers, one composed multiple quantum wells and other bulk indium gallium arsenide phosphide. Introducing these to an generic foundry platform required zero process modifications. Theoretical, simulation,...
Advanced oxidation processes, like UV/H2O2 oxidation, are important barriers against organic micro pollutants in drinking water treatment. In order to guarantee safe water, it is be able predict the reactors' performance adjust operating conditions actual influent characteristics (like UV transmission) and lamp performance. Therefore, a design tool was developed, which based on kinetic model that describes predicts direct photolysis of compounds pilot experiments, using Low Pressure (LP)...
Forward osmosis (FO) is a concentration driven membrane process which recently gained an increase in attention due to the development of improved FO membranes. Most currently available data on research obtained small laboratory-scale set-ups, thereby overlooking effects scaling-up pilot or full-scale size. In this paper, experiments are carried out with 10.16 cm (4-in) spiral wound (SWFO) Hydration Technologies Innovations (HTI) module. The performance SWFO module was investigated during...
Abstract This paper describes the results of experiments performed in a high-recovery system to elucidate silica scaling phenomenon and characterize scaling.

We developed two types of diode temperature sensors on the InP-based generic foundry platform, with no process adaptations required. These showed sensitivity from -1.1 to - 2.1 mV/K and were not affected by on-chip light.
AbstractUV/H2O2 processes can be studied using a Collimated Beam (CB) setup. In UV dose calculations, the "water factor" accounts for changes in irradiation spectrum upon its way through aqueous solution. Analogous to "germicidal factor," "extinction is introduced, correcting fact that resulting compounds will subjected an emission changing over depth. Using extinction factor, fluence-based photolysis and oxidation rate constants of model compounds, as well quantum yield nitrite formation,...
Increasing concentrations of organic micropollutants, like pharmaceuticals, in surface water may require additional treatment for drinking production. The UV/H2O2 process is very effective this purpose, but known its relatively high energy demand. This demand be decreased by improving the matrix composition and/or optimizing UV reactor geometry. Thus, operational costs decreased. can visualized calculating Electrical Energy per Order (EEO). By matrix, e.g. pretreating filtration over...
Literature data on the effect of calcium biofilm structures induced a preliminary study. The removal by water softening (<1.0 mg Ca2+.L−1) under real-world drinking conditions formation was studied in pilot plant with reverse osmosis (RO) membranes and laboratory-scale production unit (BPU) plasticized polyvinyl chloride (PVC-P) glass as substratum. results showed halving exponential biofouling rate RO membrane also carbohydrate (CH) PVC-P BPU water. In biofilms, did not affect...
Advanced oxidation processes, are becoming important barriers against organic micropollutants in water treatment. To guarantee safe drinking water, it is to be able adjust the process parameters circumstances. Modeling can play an role this respect. Two models, UVPerox I and II, were developed, which kinetic of combined with computational fluid dynamics (CFD), accounting for hydrodynamics UV irradiation distribution reactors applied. Both models applied several pilot reactors, good...
