REMOVAL OF SILICA Water Treatment Waste Water

Another important source of silica in water is the sand watertreatments filter. When water treated by lime-soda process is filtered through a sand water filter, a good amount of silica dissolves in it (forming calcium and magnesium silicates) due to alkaline nature of waters.

2020-2-14 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.
