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.

Abstract: An Atmospheric Storage Tank designed to be an alternative to the existing RO pressure storage tank; it functions on water pipeline pressure. It eliminates the disadvantage of subjecting the RO system to back pressure on feed water which reduces the efficiency of the system and it also will have higher probability of leakage. It requires a Pumping Gadget to pump the water when it is installed below the faucet. It is primarily designed, although not exclusively, to be used together with the ZERO WASTE RO system under patent application PCT/SG2015/000124 where there waste water tank to store the pipeline water and when combined, we can have an economical and simplified RO water filter system with less maintenance.

Abstract: A Device which can salvage the waste water from Reverse Osmosis Water Filter up to 100%, in others words, “Zero Waste”, without using electricity and electrical pump, and regardless of whether hot water pipeline and hot water tank are available. It channels the waste water into the cold water pipeline. This Device can be utilized in new Reverse Osmosis Water Filters and existing Reverse Osmosis Water Filter units. This Device consists of two components, a water tank and a special gadget. The special gadget is installed inside the water tank and is not exposed to external view. The water tank can be of various sizes to suit usage requirement. The Device is connected to the outlet of the said waste water outlet, the pipeline Inflow and the outflow to the faucet. The water tank is for receiving and storing the waste water and the special gadget is for salvaging and channelling the waste water to the faucet outlet, when the faucet is turned on, thereby salvaging the waste water.
