At plants where silica in the brine is high, the plant usually designs and installs a process to either remove silica via a crystal reactor clarifier (CRC) or increase its solubility by dropping pH by adding acid (known as "pH mod"). Both of these options are extremely expensive to install and maintain. For many years, water treatment
