These products are commonly used to help control calcium carbonate, calcium phosphate, calcium sulfate, and many other scales and deposits. As increasing demand for water conservation and reuse, and the need to use water of lesser quality, scales of silica, barium, strontium, and struvite are beginning to appear in cooling water and reverse osmosis. Scale is even appearing in wastewater applications.
What is scale?
A scale is soluble material in water which precipitates, becomes insoluble, and deposits on a surface. Various factors like temperature, pH, alkalinity, over saturation, or a change in water chemistry can affect the development of scale. Cooling water treatment scale can inhibit heat transfer and restrict water flow. Scale within a boiler will reduce heat transfer which reduces the boiler’s efficiency. In reverse osmosis, scale can restrict the flow and foul the membrane.
