Efficiency of membrane-sorption integrated processes

Analytical modeling of steady-state filtration process in an automatic self-cleaning filter

“…Hence it opens up the route for models aiming at optimizing the operation of the automatic filter and/or optimizing its design. determined analytically as before using the solution proposed in Koltuniewicz et al (2004). This solution reads, We recall that the origin of the coordinate system is at the center of the channel here (hence the filter media is at y = 1 and the center of chamber is at y = 0).…”

“…The analysis is based on a 1D flow model, which has been used in previous filtration studies for low to moderate filtration velocities. The main features of the model are recalled here but more details can be found in references (Gan and Allen, 1999;Koltuniewicz et al, 2004).…”

“…Gan and Allen, 1999;Koltuniewicz et al, 2004;Oxarango et al, 2004), it is important to realize that aiming at optimizing operating conditions or filter design, this simplified model is much easy to use for a parametric study than 3D CFD simulations that are less affordable in terms of computational time.…”

Utilization of geothermal water as irrigation water after boron removal by monodisperse nanoporous polymers containing NMDG in sorption–ultrafiltration hybrid process

“…A high efficiency in the process could be reached with sorbent beads with small particle sizes due to the increased surface area and enhanced kinetics [12,15]. It was reported that the high intensity of the process is achieved due to synergetic effects of sorbent concentrating at membrane vicinity [15].…”

“…A high efficiency in the process could be reached with sorbent beads with small particle sizes due to the increased surface area and enhanced kinetics [12,15]. It was reported that the high intensity of the process is achieved due to synergetic effects of sorbent concentrating at membrane vicinity [15]. According to the literature, the best results could be obtained when flux is maintained below critical value and when the permeate flux is fully synchronized with the sorption kinetics and rate of sorbent renewal on the membrane surface [15].…”
