BLADDER TANKS 

The surge protection is mainly achieved with two types of bladder tanks

Air in bladder type

In air in bladder tanks air is charged within the bladder inside the tank and the air charge  losses due to absorption are minimum since air does not come into contact with the liquid in the tank.The bladder is made from a highly elastic rubber, such as butyl rubber, and may be sized to expand to fit the entire vessel. The bladder will typically be pre-charged at installation with a pre-determined pressure to give the correct operating level in the tank when the unit is connected to the main and at the operating pressure.  To prevent the bladder from being drawn into the main at low pressures  an anti extrusion plate is fixed at the outlet of the vessel .The anti- extrusion plate and inlet size are so selected that they do not restrict  the flow in and out of the vessel.  The tank material is chosen compatible with the liquid since it comes in contact with the tank inner surface while flowing in and out from the main line.

 

Water in bladder type

In water in bladder tanks air is charged within the tank and the water from the mains flows in and out into the bladder . The air charge  losses due to absorption are minimum since air does not come into contact with the liquid in the bladder. The bladder is made from a highly elastic rubber, such as butyl rubber, and may be sized to expand to fit the entire vessel. The whole tank will typically be pre-   charged at installation with a pre- determined pressure to give the correct     operating level in the tank when the unit is connected to the main and at the operating pressure.  To prevent the bladder from being drawn into the main at low pressures  an anti extrusion plate is fixed at the outlet of the vessel .The anti- extrusion plate and inlet size are so selected that they do not restrict  the flow in and out of the vessel.  The Bladder material is chosen compatible with the liquid since it comes in contact with the bladder inner surface while flowing in and out from main lines
