Why use CapDI for your crops? With a growing world population and tighter regulations on water use being introduced, the demands on horticulture to act more responsibly are ever increasing. Too much sodium in irrigation water causes yield loss, hampers water and fertilizer reuse, and leads to crop damage; especially for sensitive crops such as tomatoes, peppers and berries. CapDI tunably removes and controls sodium and electrical conductivity (EC) levels arrising from total dissolved solids (TDS) without removing all minerals, allowing users to select the optimal level of sodium and minerals for each crop’s irrigation water. Excessive levels of sodium in irrigation water prevents reuse, and CapDI effectively removes the sodium to acceptable levels (< 1 mMol/L) in the presence of high silica content (> 80 mg/L) while maintaining high recovery (> 80%) at flexible removal rates (50 - 90%). Horticulture businesses benefit from using CapDI by its low energy consumption, no required chemicals, minimal maintenance, as well as overall reduced water and fertilizer consumption. CapDI provides optimal water quality that enables higher quality products at better yields, all while dramatically lowering operational costs! How does it work? Water flows between electrodes in a 2-step process. Electrode surfaces are separated from the water by membranes that selectively allow positive or negative ions to pass.

Purification: Saline water passes between oppositely charged electrodes, which electrostatically remove dissolved ions, leaving pure water flowing out of the cell.

Regeneration: Feed water flushes through the cell at a lower flow rate, while electrode polarity is reversed. Ions are rejected from the electrode surface, concentrated in the flow channel, and flushed from the cell.
