 · Granular silica removal. Silica can exist in water as relatively large particles, known as silica granules or granular silicates. Granular silica removal is generally accomplished through physical chemical separation. The most common approach is lime softening, which is a process where calcium hydroxide (lime) is added to water to remove hardness.
