Descaler
Generally, industrial water used in manufacturing plants includes inorganic salts such  as calcium and silica.
While the industrial water is recycled for a long time, the inorganic salts are condensed to solidify, which leads to contamination in water storage tanks or blockage in water pipes to bring decrease in performance of water treatment equipment or even decrease in quality of products manufactured  in the plants.
Here are photos showing well-known contaminated conditions of the inside of the water pipe and the industrial water after a certain period of recycle use of the industrial water in a manufacturing plant.
