What is limescale in plumbing?
What is Limescale? Limescale is the hard, off-white chalky deposit found in kettles, on air dried cooking utensils, bathroom tiling, hot water heater elements and on the inner surface of old pipes. It can also be found on taps where hard water has been continually running through. Scale is generally caused by hard water.
Is limescale hard to clean?
Limescale is unsightly and hard to clean. Lime scale can impair the operation of various components (such as water heater elements) or damage them. In faucets, limescale reduces the flow of water. In kettles, limescale acts as an insulator, impairing heat transfer.
What is the function of lime in water treatment?
The functions of lime in water treatment. Lime in all its forms – quicklime and hydrated lime, as well as calcined dolomite – are the most effective and cost efficient alkaline products used in the making of drinking water, as well as in the treatment of waste water and sludge.
Why use quicklime in water treatment?
This is because the magnesium in the dolomite acts as the main reactive agent for the elimination of silica. The use of quicklime and slaked lime is much less common. Thanks to the use of lime in water treatment plants an improvement in the taste, smell and colour of the water is achieved, among other benefits, ...
