Boron removal

Plants need very little boron and many crops are sensitive to excess, which shows as leaf damage and lower yield. In one AFG greenhouse project in Ankara, boron in the well water was reduced from 2.8 ppm to under 0.1 ppm at 15 m³/h using RO and filtration.

Reverse osmosis, second-pass RO, boron-selective ion exchange resins and selective adsorbents can all be used. The right technology is chosen from the raw water analysis, including pH, conductivity, TDS, hardness, silica, iron and manganese. Often RO handles salinity and boron together, with a polishing step only where the crop needs very low boron.

Not always. Boron passes RO membranes more easily than most salts, and rejection depends on pH and membrane type. When the target is very low, a second RO pass or a boron-selective resin is added. The membrane type and operating pH are set in the design to get the most boron rejection from the first pass.
