This invention relates to make the water purification through reverse osmosis membrane system more cost effective. The system works with any household or irrigation pump. Thus, reduces the overall cost of the water purification through reverse osmosis membrane and filters.

The reverse osmosis water purification system currently present in the market cost a lot. It has its own pressure motor. Due to this motor and high aesthetic appearance the cost of reverse osmosis water purification is very high.

4. DESCRIPTION (Description shall start from next page.)

This invention reduces the cost of reverse osmosis water purification system at high extent. This invention incorporates two parts, one is the 'module' for the connection with any kind of water pump and a frame with slot to fit the filters and reverse osmosis membrane. People having water pump for filling roof water tank or for irrigation can assemble first part i.e., module at the outlet of the pump and they can assemble any kind of filter and reverse osmosis membrane on the frame and can get the purified water when required at a very low cost and at the same time if purification is not required one can bypass the water for its normal use. This module and frame reduces the cost of reverse osmosis purification system because of the utilization of the preexisting pump and one can buy cost effective filters and reverse osmosis membrane for the frame. Reduction in the cost of water purification may leads to the accessibility of water for more people and ultimate the effect of water borne diseases will be less.
In this invention, the first part i.e., module has one inlet for the water pump and two outlets. The inlet can be attached to any kind of water pump e.g. irrigation pump or household pump. Outlet I of the module is connected to the inlet of the frame. Outlet II is for the normal use of water pump (i.e., for its actual use like irrigation or roof tank feeding). The flow between two outlets is regulated by a tri-valve. There is another bypass assembly between the outlet I and outlet II with a regulatory ball valve. This regulatory ball valve regulates the pressure required for the reverse osmosis membrane and also directs the excess water towards the outlet II for the normal use. The rejected water from reverse osmosis membrane is also connected to the outlet II that reduces the water wastage. Assembly of this frame and module is very easy and can be done by any person.

To assist with the understanding of the invention, illustration and details will be made using drawing for reference, which shows one representation of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 can be seen that the module is a specific arrangement of the tubes, tri-valve and regulatory valve. The diameter of the tubes may vary according to the pump. The module contains an inlet 1 for receiving the water from the pump. The direction of water in the module is controlled by the tri-valve 4.

The direction of water flow, when the filtration is not required but the pump is required for its normal use can be seen in 10. In this the water comes from the inlet 1 and goes for the normal supply from outlet-II 3.
The direction of water flow when water filtration is required can be seen in 11. At this time, the tri-valve is open towards outlet-I 2. The outlet-I 2 is connected to the reducer 8 of 1/4 inch diameter and this reducer 8 is connected to the inlet of frame input 5. There is another bypass connection 6 between the outlet-I 2 and outlet-II 3. This bypass contains a regulatory valve 7. This regulatory valve 7 is utilized to produce sufficient pressure for the reverse osmosis water purification process. While regulatory valve 7 remains completely open it allows all water to bypass towards its original way. As one starts closing the valve 7, the movement of water starts towards the inlet of the frame input 5. By manual observation, one can fix the position of the valve 7. In order to fix the position one can start with the complete open position of valve 7. At this time all water passes through the bypass 6. Now one has to start closing the valve 7 very slowly, at one instant of time will find drop of water from the outlet of frame 23. Then the valve has to be closed up to that point where one can observe the beginning of the continuous flow. At that point the process has to be stopped. This will be a fixed position for that particular pump; this position may vary according to the model of pump. During filtration the excess water in outlet-I 2 should bypass to the normal outlet-II 3 of the system.

Referring to FIG. 2 one representation of frame 23, contains four slots 11, 12, 13, 14. This frame
23 is designed for the 4 stage reverse osmosis water purification system. All slots 11, 12, 13, and 14 contains hook 15, 16, 17 and 18 respectively. Slots 11, 12, 13 and 14 are for fitting sedimentation filter 25, pre carbon filter 26, reverse osmosis membrane house 27 and post carbon filter 28 respectively. Hanger 19 and 20 is for hanging the frame on the wall.

24 show the schematic representation of frame 23 with all the filters and membrane house. The inlet 29 of sedimentation filter 25 is connected with the inlet 5 of frame 23. The outlet 30 of sedimentation filter 25 is connected to the inlet 31 of pre carbon filter 26. The outlet 32 of pre carbon filter 26 is connected to the inlet 33 of reverse osmosis membrane house 27. Reverse osmosis membrane house has two outputs 34 and 35. The outlet 35 gives pure water and it is connected to the inlet 36 of the post carbon filter to remove the odor and enhances the taste. The outlet 37 of the post carbon filter 28 is connected to the outlet 21 of the frame 23. The outlet 34 of the membrane house 27 is connected to the flow restrictor 38. The output 39 of the flow restrictor is connected to the output -II 3 of module 9. The pure water from the output 21 can be collected in a reservoir container 22.

The obtained water contains less Total Dissolved Solute (TDS) due to reverse osmosis process and thus one can obtain a good quality of water.
