A modular filtration device is composed of a modular docking plate having at least one quick disconnect plumbing coupling; at least one electrical connector; and at least one alignment feature for aligning and receiving a modular filter; and a modular filter composed of a docking face having: at least one quick disconnect plumbing coupling; at least one electrical connector; and at least one alignment feature that mates with an alignment feature of the modular docking plate to provide proper alignment of the filter with the docking plate, engagement of the quick disconnect plumbing couplings, engagement of the electrical connectors, and engagement of the locking mechanism.

The present invention is directed to an electrochemical device for at least partially removing or reducing a target ionic species from an aqueous solution using faradic immobilization, the electrochemical device including at least one first electrode and at least one second electrode with different void fraction and surface area properties, due to differences in void fraction (also referred to as void ratio) of the at least one first and the at least one second electrode, water flows through an electrode with a high porosity, while the aqueous solution does not flow through an electrode with a low porosity.
