“…4). This is resembles the results that would be obtained for ideal cake filtration [11]. The resemblance with the ideal case is caused by the fact that the pump efficiency shows very little variation and has therefore a small influence on the shape of the filtration trajectory.…”

“…For dead end filtration, it was found that under the assumptions of the ideal blocking laws, a reduction in energy consumption is possible by applying constant power filtration [11]. Compared to constant flux and constant pressure filtration the reduction in energy consumption is usually small, except in cases where the fouling mechanism resembles standard blocking and the fouling resistance is large.…”

A control strategy aimed at minimizing energy consumption is formulated for non-ideal dead-end cake filtration with an inside-out hollow fiber ultrafiltration membrane system. The non-ideal behavior was assumed to originate from cake compression, non-linear cake resistance and a variable pump efficiency.Constant gross power, constant flux and constant pressure filtration were considered as alternatives for the optimal operating strategy. It was found that the ratio between the initial and final total resistance determines whether a large difference between these strategies occurs. This is mainly determined by the specific cake resistance, the final state and the membrane resistance.When there is a large difference between the operating strategies, the pump characteristics determine which suboptimal strategies are attractive. For a pump with a low head and a large capacity, constant flux filtration is nearly optimal, whereas for a pump with a large head and a small capacity optimal operation is closer to constant pressure filtration. Under the investigated conditions there was no significant difference (<0.5%) between the constant gross power and the optimal operating strategy.

“…While the flux decline behaviors are examined in constant pressure filtration, the pressure rising behaviors resulting from the increase in the filtration resistance are investigated in constant rate filtration in which the filtration rate is kept constant (Blankert et al, 2006;Liu and Kim, 2008;Sun et al, 2008;Mahdi and Holdich, 2013;Raspati et al, 2013).…”

Blocking filtration laws consist of four different filtration mechanisms: complete blocking, standard blocking, intermediate blocking, and cake filtration. Blocking filtration laws for describing both the pore blocking and cake formation have been extensively employed over the past several decades to evaluate the increase in filtration resistance with the progress of filtration in the field of classical particulate filtration. In recent years, blocking filtration laws become widely used also in membrane filtration such as microfiltration and ultrafiltration of colloids. This paper gives an overview of the developments of blocking filtration laws and equations under constant pressure and constant rate conditions reported for the filtrate flow of Newtonian and non-Newtonian fluids. The fouling index evaluating the degree of membrane fouling was examined on the basis of the blocking filtration equations. The blocking filtration laws were reexamined to extend the range of their application. Moreover, various combined models developed based on the blocking filtration laws were introduced for describing more rigorously the complicated filtration behaviors controlled by more than one mechanism which occurs successively or simultaneously.

During emergency situations, effective and quick reactions are vital in order to supply 7 safe and unpolluted drinking water within approved guidelines Point-of-use water 8 treatment (PoUWT) system, for instance, portable membrane-based water treatment 9 devices, could help affected people to survive while waiting for aids to arrive. In the 10 context of portable membrane-based water purification devices, it is also found that 11 the most literature does not mention particle depositions and interactions, and 12 membrane fouling mechanisms that might occur in these devices.
