In this contribution we present a simulation test-bench capable of separating and quantifying all the major sources of uncertainties in user-designed direct calibration/de-embedding test-fixtures. The calibrated data systematic errors arising from the different response of the st ...

Porosity of spacer-filled channels in spiral-wound membrane systems

Quantification methods and impact on hydraulic characterization

The porosity of spacer-filled feed channels influences the hydrodynamics of spiral-wound membrane systems and impacts the overall performance of the system. Therefore, an exact measurement and a detailed understanding of the impact of the feed channel porosity is required to unde ...
Feed spacers are an essential part of spiral-wound reverse osmosis (RO) and nanofiltration (NF) membrane modules. Geometric modification of feed spacers is a potential option to reduce the impact of biofouling on the performance of membrane systems. The objective of this study wa ...
The paper, through a “regenerative” lens, has focused upon a new conceptual game system involving transaction costs (TCs) for creating a more accessible green buildings (GB) market. Individual stakeholders steadfastly guard their own interests in any investment decision, which se ...
