Cyclone Filters

Cyclone Separators (Sand Separators) are used for separation of sand silica like high density particles from water.   Minimum operating pressure of 2 kg/cm2 is required for smooth functioning as these hydro cyclones are working on centrifugal motion, for which positive operating pressure is required.

Tangential entry is provided at the inlet which allows water to enter in cyclonic motion. Also inside the vessel particular type of slotted pipe is provided which further accelerates the velocity resulting heavier particles falling at the bottom and water being a lighter density going out from outlet from the top. At the bottom there is a diverter plate provided in the collection chamber which allows dirt to enter into  collection chamber and there are wave breakers provided in the collection chamber which allows dirt to settle in the collection chamber to reduce the velocity  with  drain and manual valve along with electrical  and pneumatic valve provided with a small control panel  with a timer at bottom.

It is purely static equipment apart from the motorized  valve at the bottom.  There is no mechanical barrier hence there is no maintenance required  or choking takes place in the Separator  body. The drain valve timer is normally set between 30 to 60 seconds longer duration depending on the dirt load available  and seasonal variation , some time impurity load is very high.  In that case you can keep drain valve continuously open to allow dirt to drain out from the collection chamber.

There is a normal pressure drop at the inlet and outlet of 0.2 to 0.3 kg/cm2 and as there is no blockage or choking, as the pressure drop remains continuous during operation.
