1. A cross-flow membrane filtration channel used in filtration of a liquid feed, the channel comprising:
an inlet and an outlet, wherein a centreline of the channel is defined from the inlet to the outlet;
the liquid feed in the channel, the liquid feed comprising particulate foulants, wherein a direction of flow of the liquid feed in the channel is defined along the centreline from the inlet to the outlet of the channel; and
at least one liquid-permeable membrane configured for filtration of the particulate foulants in the liquid feed based on size of the particulate foulants and for filtered liquid permeate to pass through the at least one liquid-permeable membrane, the channel being defined by the at least one liquid-permeable membrane,
wherein at least one surface of the channel is inclined at an angle away from the centreline of the channel in the direction of liquid feed flow in the channel, such that the particulate foulants in the liquid feed embark on trajectories away from the at least one liquid-permeable membrane to thereby reduce fouling of the at least one liquid-permeable membrane.
