Dataset for "3D Printed Fouling-Resistant Composite Membranes"

Data collection method:

Numerical simulations: the conservation of mass and momentum equations, and particle tracing model for steady state and laminar flow conditions were solved by using a commercial CFD software COMSOL MultiphysicsTM v5.4 to elucidate the fluid mechanics of the filtration process of flat and wavy 3D composite membranes. Fabrication of membrane support: the building material for the membrane support was a UV-cured polyurethane acrylate oligomer with the commercial name VisiJet M3-X. This ABS-like thermoplastic material has a high tensile strength and resistance to temperature along with good durability and stability which make it suitable being a membrane support.34 The support material was hydroxylated wax with the commercial name VisiJet S300. Fabrication of the 3D composite membranes: there were three main steps to fabricate the 3D printed composite membrane: (i) printing of the 3D supports, (ii) preparation of selective layer by non-induced phase separation and (iii) deposition of selective layer over the support. Filtration and anti-fouling performance: the filtration performance of the membranes was evaluated by using a circulating cross-flow apparatus (Figure S1 in the Supporting Information). Prior to the filtration experiments, the membranes were pre-compacted using pure water at 2 bar until steady permeance was reached. The required duration for pre-compaction was just less than 2 hrs.
