Industrial Water Treatment

Carbonate deposits are found in rocks, in water and even on Mars. These are harmful for various reasons and can be dangerous if not treated for human and industrial consumption. River water contains 46-48% bicarbonate ions. Water hardness refers to calcium carbonate molecules that form a lime scale deposit in water pipes, faucets, and reservoirs. Inside a boiler scale is formed due to this water hardness. These hardness salts have to be removed to prevent overheating and boiler explosion due to tube failure. Scale in boilers can also impact energy costs and reduce efficiency.

An effective way to get rid of water alkalinity is de-alkalization which reduces the hardness and the bicarbonate content of the water, thus reducing the salt content in the water by about 75%. De-alkalization removes hardness salts from water used in boilers.
A de-carbonator is used for removing carbons. It has an inlet and an out let. Water to be purified passes through the inlet of the forced draft de-carbonator, the forced draft de-carbonator provides an initial reduction in the level of carbon dioxide in the water while the vacuum de-gasifier provides a further reduction in carbon dioxide level as the water is processed.

Dissolved solids in the water can also be removed using chemicals, osmosis, reverse osmosis. The water treatment methods rely on your water utilization, and the best thing to do is look up a water purification specialist in the field.
