The patented technology relates to the technical field of water treatment, in particular a siphon composite ultrafiltration membrane filter component and a gravity water filter tower purification.
The technology allow to provide a gravity water purification equipment, called water filter tower / tank, including the receiver tank and the siphon type gravity composite membrane filtration module as mentioned above, the siphon-type composite filtration module is fixed at bottom of the receiver tank, and there is a water tap at membrane module cover, which is fixed outside of receiver tank.
As a preference, one side of the tank is equipped with a level control valve for the water level control, and the level control valve is equipped with a float for detecting the level.
Further, the height of the float is 2 to 8 times of the outer diameter of membrane module, here select here select 1-2m for running.
As a preference, the bottom of the tank is equipped with a discharge valve for the removal of residual dirt mud.
