Abstract
An Atmospheric Storage Tank (AST) system designed to be an alternative to the existing RO pressure storage tank that operates on water pipeline pressure. It eliminates the disadvantage of subjecting the RO system to back pressure on the feed water which reduces the efficiency of the system and also has a higher probability of leakage. When the AST system is installed below the faucet, a pumping gadget is required to pump the water. It is primarily designed, although not exclusively, to be used together with a zero waste reverse osmosis system.
Claims9
An Atmospheric Storage Tank (AST) system configured to store filtered water from a Reverse Osmosis (RO) filter without utilizing a pressure tank for pumping the water and without an electrical device for controlling the supply of water to the RO filter via an inlet water pipeline comprising:
- an atmospheric storage tank having (i) a tank inlet in communication with an outlet from the RO filter and (ii) a tank outlet in communication with an outlet of an RO faucet;
- a float valve which includes a float and a valve box;
- wherein the float is positioned in the AST and the valve box is positioned outside of the AST;
- wherein the valve box is in fluid communication between the inlet water pipeline and the RO filter;
- wherein the float valve is configured to open and close at a required interval to control the flow of water from the inlet water pipeline to the RO filter;
- wherein when the AST is installed above a level of the RO faucet outlet, the filtered water can be collected from the RO faucet outlet through gravitational force;
- wherein when the AST is installed below the level of the RO faucet outlet, the AST system further comprises a pumping gadget, and the RO faucet includes the inlet water pipeline and an outlet water pipeline to drive the pumping gadget to deliver the filtered water to the RO faucet for collection;
- wherein the valve box further comprises a valve and a seesaw like structure with a ball bearing supporting a piece of lead weight;
- wherein the seesaw like structure consists of a track with the ball bearing travelling on the track and the piece of lead weight is supported on the ball bearing;
- wherein the valve and the seesaw like structure are parallel to each other and they are fixed on to a valve box side shaft and the shaft is supported by two ball bearings;
- wherein the shaft follows a movement of a float side shaft and moves the piece of lead weight to and from both sides and at the same time opens and closes the valve simultaneously;
- and
- wherein the valve functions automatically once connected and water supply is turned on.
