Brackish water, in one sense, is defined as a fresh low TDS water source that experiences a large increase in normal TDS due to seawater intrusion. In the RO field, brackish water can be defined as feed water with low to medium TDS levels (up to 10,000 to 15,000 ppm) that can be treated with a "brackish RO element" designed for 600 psi maximum applied feed pressure.
