Abstract
Solids precipitate out of an aqueous solution after it has passed through a negatively charged tubular steel electrode and then through the annular space between the negatively charged electrode and a positively charged tubular aluminum electrode.
Claims7
The method of purifying water, comprising the steps of
- mounting a first tubular electrode within a second tubular electrode in mutual concentric spaced relationship,
- maintaining said first electrode at a negative potential relative to said second electrode,
- flowing said water in an axial direction through said first tubular electrode from one end to the other,
- then flowing said water in a reverse direction through the space between said first and second tubular electrodes, and then
- separating solids entrained in said water from said water.
2 more elements
The method of purifying water, comprising the steps of
- flowing said water through a first tubular electrode and through the annular space between said first electrode and a second tubular electrode surrounding said first electrode, and
- maintaining said first electrode at a negative potential relative to said second electrode,
- whereby soluble impurities entrained in said water are caused to precipate out of solution.
