1. A method of removing phosphorus from water, the method comprising:
immersing an electrochemical cell in water comprising phosphorus to form treated water comprising a salt that comprises the phosphorus, the electrochemical cell comprising
an anode comprising Mg, Al, Fe, Zn, or a combination thereof, wherein the anode comprises a planar nonporous form,
a cathode having a different composition than the anode, the cathode comprising Cu, Ni, Fe, or a combination thereof, wherein the cathode comprises a wire mesh, wherein the cathode is arranged parallel to a major face of the planar nonporous form of the anode such that a gap is formed between the major face of the planar nonporous form of the anode and the cathode, and
at least one conductive connector connecting the cathode to the anode, wherein the conductive connector maintains the gap between the cathode and the major face of the planar nonporous form of the anode; and
separating the salt comprising the phosphorus from the treated water, to form separated water having a lower phosphorus concentration than the water comprising phosphorus.
