In water treatment, we are concerned with silica because of its capacity to form scale deposits on surfaces it comes in contact with. The silica content of water ranges from a few parts per million in surface supplies to well over 100 parts per million in certain well waters. In its colloidal form it consists of very fine particles in suspension.
