Implementing a properly designed chemical water treatment program is the simplest method of preventing these corrosion problems. Raw water quality must be taken into consideration when determining the most effective type of treatment program. For example, the Greater Vancouver regional water supply has an extremely corrosive tendancy due to the high concentration of corrosive dissolved oxygen, acidic pH and low mineral content. Chemicals Ltd. has formulated a diverse range of inhibitor programs to meet the needs of the G.V.R.D. raw water supply and any other varying raw water conditions. Prevention of Scale Formation of scale deposits will result in a loss of cooling transfer efficiency, translating directly into increased cooling costs.
Raw water contains varying amounts of mineral salts such as calcium, magnesium, iron and silica.
When these minerals exceed their solubility point due to increased cycles of concentration, the minerals precipitate out of solution and produce scale forming salts. It is essential to maintain a proper bleed-off schedule to prevent excessive over cycling. Chemicals Ltd. has formulated inhibitor programs to prevent minerals from precipitating out and forming scale deposits. This aids our customers in running at higher cycles of concentration, when compared to operating untreated systems, reducing water usage and discharge. This creates fouling on the inside surfaces of condenser systems which can lead to under-deposit corrosion and loss of cooling transfer efficiency.
