ABSTRACT:
A fluid treatment apparatus is disclosed which includes a casing through which fluid flows, an array of magnets in the casing, arranged substantially perpendicular to the side of the casing and therefore substantially perpendicular to the main flow of fluid through the casing, wherein the magnets within the array which lie substantially within the same perpendicular plane are spaced apart and arranged in alternating polarity, and means to support the array of magnets such that the space between the magnets within the array which lie substantially within the same perpendicular plane are substantially equal distances from the adjacent magnets to permit flow of fluid therethrough. In a one arrangement, the casing includes an outer casing made from a material which substantially restricts the magnetic field within the casing. An inner casing is made from a non-magnetic material such as stainless steel. Another arrangement of a fluid treatment apparatus includes an array of magnets in the casing, arranged in planes substantially perpendicular to the side of the casing and therefore substantially perpendicular to the main flow of fluid through the casing.
