How Do You Remove Silica from Industrial Water and Wastewater?

The most common approach is lime softening, which is a process where calcium hydroxide (lime) is added to water to remove hardness. The lime works by triggering the precipitation of hardness ions (calcium and magnesium), which form flocs that can be settled out of the stream.
