A. FIELD OF INVENTION:
The present invention relates to dual water purification technology. More particularly, the present invention discloses SensePure Advanced Dual Water Purification technology with SEAD water purification technology using Surface Electro-Adsorption Desorption (SEAD) unit along with Intelligent Rejuvenating Auto-cleaning (IRAC) unit, Auxiliary- recirculation Performance Booster (ARPB) unit, Performance Enhancement logic (PEL) unit, Smart Water Flow Algorithm (SWFA) encoded microprocessor unit technology with minimum quantity of drinking water wastage for point of use (POU) domestic water purifier.
B. BACKGROUND ART
Different systems have been developed to remove contaminants from water. Examples of such systems include various methods, such as filtration, physical adsorption, capacitive desalination and/or Advanced Oxidation Processes (AOPs), to treat organic, inorganic, and biological contaminants in water.
Filtration is a process in which contaminants are physically removed by size exclusion. Known filtration processes include, for example, reverse osmosis and microfiltration. Disadvantages of filtration include clogging of the filter pores with contaminants, often resulting in fouling and frequent replacement of the filter. In some applications, this may result in high maintenance costs.
Capacitive Deionization (CDI) is an electro-adsorption technology. When an electric potential is applied to the electrode, the ionic substances move and adsorb to the electrode surface by the adsorption reaction in the electric double layer formed on the electrode surface (ion adsorption reaction); when the adsorption capacity of the electrode reaches its limit, the electrode is regenerated by short-circuiting the charged electrode to desorb ionic materials (ion desorption reaction).
As such, the electro-adsorption technology is very easy to operate because it can adsorb and desorb ions by changing only the potential of the electrode. Also, since the applied potential is operated at a low voltage where electrolysis does not occur, the energy consumption is lower than that of the existing desalination process. There are features that can be significantly reduced.
In the prior art, a Chinese specification CN201132787Y discloses an Electro-adsorption demineralization water purifier, which comprises a high-precision pretreatment filter element, an electro-absorptive filter element, an electrical control circuit board, and a water quality probe capable of detecting the content of salinity in water. After suspended substances and particulate matters in raw water are removed through the high-precision pretreatment filter element, then the salinity in the water is removed through the electro-absorptive filter element, the water quality probe is arranged in a water outlet pipeline of the electro-absorptive filter element; the water outlet pipeline is divided into two paths behind the water quality probe; and one path is a freshwater pipeline communicated with a water purification tank, while the other path is a sewage pipeline which is communicated with a sewage tank or is emptied.
In another prior art, a Chinese specification CN203284279U discloses a Self-cleaning electric adsorption water purification device. The electric adsorption water purification device comprises a first electrolytic system and an electric absorption-desorption system. The first electrolytic system comprises a first electrode assembly comprising a first positive electrode and a first negative electrode. Harmful materials in water are ionized by ionizing and exciting the water with the powered-on first electrode assembly. The electric absorption-desorption system comprises at least one electric absorption-desorption unit, which is provided with an absorption material electrode therein. By turning on the power of the electric absorption-desorption unit, the harmful materials with the ions can be absorbed by the absorption material electrode, and by replacing the polarity of the absorption material electrode of the electric absorption-desorption unit by controlling the power supply, the harmful materials on the absorption material electrode can be desorbed. The first electrolytic system is connected with the electric absorption-desorption system. The self-cleaning electric adsorption water purification device can efficiently remove harmful materials without replacing filter cores and retain beneficial mineral substances.
Accordingly, it is desirable to provide water treatment systems and methods that overcome some of the aforementioned disadvantages and limitations of known water purification techniques.

I. ESSENTIAL MODULE IN THE INVENTION:
1. SMART WATER FLOW ALGORITHM (SWFA) PROCESS
Potential Difference on SEAD maintained by H – Bridge; [FIGURE 4]
• The operating voltage of SEAD is controlled using an electronic H-Bridge embedded in Micro Controller PCB.
• Initially, all the relays in H-Bridge will be off.
• To apply zero potential to both terminals of SEAD, we need to turn on both the lower relays of the H-bridge. (S2, S4).
• To apply a positive voltage to SEAD, you need to turn on the cross relays of the H bridge. (S3, S2).
• To apply a negative voltage to SEAD, turn on the other pair of cross relays on the H Bridge. (S1, S4).
2. ARPB [Auxiliary Recirculation Performance Booster] Unit. – [FIGURE – 5]
In the current invention, the main differentiation generated by the accurate location of the ARPB unit is the water flow diagram. As the name suggests, the ARPB unit acts as a secondary water storage and recirculation place and enhances water purification with consistency in the mineral content in each purification zone.
ARPB unit is an empty food grade plastic (ABS/PP/PC, HDPE, etc.)/steel (SS 304)/glass closed container with five different purpose opening interfaces in the shape of cylindrical/rectangular/square with a water volume capacity minimum 200 ml to maximum capacity with respect to the dimensions of the point of use domestic water purifier [In the present invention it considered as 800ml volume] and also air vent placed at the lid of the container to provide the free flow in the gravity.
• The first open interface is named Auxiliary Inlet [1]: ¼’’, 5/16’’ & 3/8’’ Male connector used to fix in the container [By this interface, the SEAD purified water fills into the ARPB container. This inlet is connected to the Solenoid valve – V5, which is connected to the water output of the SEAD unit. Water flow to the ARPB container is controlled by the flow restrictor (FR) in the 200 ml to 1000 ml range. In the present designed water purifier, 800ml FR is used. The water filling time/intervals are controlled by the SWFA-encoded microprocessor unit & logic.
• The second open interface is named Suction Point [2]: ¼'', 5/16'' & 3/8'' Male connector used to fix in the container. This interface is connected to the inlet of the booster pump, and water flow is continued towards the outlet of the booster pump, and it is connected to the inlet of the solenoid valve V6 and outlet of the V6 connected the Pressure Reducer Valve (PRV) and it is connected to the inlet of SEAD unit. The Not Return Valve (NRV) avoided reverse flow in an accurate place as per the water flow diagram.
As mentioned above, the booster sucks the water from the ARPB unit; water passes through SV -V6, PRV and reaches to inlet port of the SEAD. This proves that double purification of water will occur; it provides dual water purification and maintains the water TDS level in the final purifier tank, and it maintains the consistency of minerals in the purified tank throughout the purification process.
And this suction interface acts as a Recirculation Zone in the purification stage by circulating the water in the same water loop (Suction Point ?Booster Pump? SV6?PRV? SEAD? SV5 ? Auxiliary Inlet). So, it helps in the double purification by maintaining the water mineral in the ARPB container in a short time sequence (Minimum recirculation time is 20 Sec required).
• The Third open is named Overflow Point [3]: ¼’’,5/16’’ & 3/8’’ Male connector used to fix in the container: This interface to avoid the over follow from the ARPB container and this interface directly connected to the drain line of the water purifier, so it will not allow the water spillage inside the unit. The LLDPE tube with size (¼’’/3/8’’/5/16'') with NRV (Non Return Valve) is connected to the interface, and another end of the tube is connected to the drain line.
• The Fourth open is named an Inlet for Rejuvenating liquid [4]: ¼'', 5/16'' & 3/8'' Male connector used to fix in the container. This interface, with a size of ¼'', is connected to a solenoid valve – V7. SV-V7 connected to the IARC Storage unit (1L). At the time-periodic SEAD cell rejuvenating cycle, the Solenoid valve – V7 opens for the specified time and rejuvenating liquid with a restricted quantity falls into the ARPB container, which is already filled with water. The Fourth open interface of ARPB controls the inlet flow of the rejuvenating liquid to the ARBP container.
• The Fifth open is named as Air Release Vent [5] for the ARPB tank ,it help release the air in the ARPB tank, the air release controlled by the silicon stopper, which can pass only air no water from the container.
3. IARC [Intelligent Rejuvenating Auto-cleaning] unit. – [FIGURE 6]
The role of the IARC unit is to rejuvenate the SEAD electrode by dissolving the scaling from its inter- and intra-surface. The IARC Storage unit consists of a rejuvenating solution with a low or high pH range that can remove the scaling from the SEAD electrode.
The Specially designed chamber with one opening interface [1] with ¼’’/5/16’’/3/8’’ male connector is connected to the ARPB chamber. The top of the container lid with an air vent [2] is placed to get the gravitational flow of the liquid without any pressure.
The rejuvenating liquid based on citric acid or citrate water is stored in a sealed or refillable plastic container. The container has an outlet interface and is connected to the inlet of solenoid valve V7, and SV7 is connected to the ARPB unit chamber. The minimum volume of the IRAC unit is 1L.
The IARC unit process has two different segments. The first one is the rejuvenating liquid with low pH (3-4) or with High pH (10-12). In the rejuvenating periodic sequence cycle (Every 200 cycle or after 250L permeate water usage or manual cleaning), a sequence minimum of 10-20 ml of the rejuvenating liquid is mixed with purified water which is stored in the ARPB unit, and the pH of the water in the ARPB unit chamber become 4 to 10 with respect to the pH of the rejuvenating liquid . The mixed solution of ARPB is passed through the SEAD electrode and rejuvenated the electrode. The pH 4 to 10 solution was recirculated through the SEAD module by the ARBP unit open interface (suction point & Auxiliary inlet). The minimum time required to rejuvenate the SEAD electrode is 5 minutes to 30 minutes.
Using the specially designed IARC unit container helps control the temperature and avoid the rejuvenating liquid's evaporation. If 20 ml of the liquid is used for every 250L purification, it works 50 times for each 250L purification, i.e., for 12500L purification or more than two years.
In the present invention, the rejuvenating process is integrated with the main water purifier, and the microprocessor controls its processing sequence. So, it is fully automated, and no human intervention is required. The rejuvenating program sequence explained in the section part 2 – Step 12.
4. SensePure Advanced Dual Water Purification technology with SEAD
As mentioned, “SensePure” is the built-in water quality sensing unit integrated with the main water purifier unit. It helps diagnose water quality and also adapts SWFA's different purification sequence programs to suit the input water. SensePure technology adapts the SEAD-based water purifier to purify input water from 0 to 2000 PPM.
In the present invention, two possibilities of SensePure are discussed, and details are mentioned below.
4.1 SensePure Water Quality Conductivity sensor in the input line:
In this sequence, it is divided into two conditions.
a. Input Water Less than 200 PPM:
First Method: The SEAD unit is the main purification to reduce the TDS of the water; if the SEAD voltage (48V/60V) continues throughout the purification, more TDS reduction in the input water will occur, leading to less TDS water. To get the mineral-rich purified water, control the SEAD voltage by reducing the voltage to less than 48V/ 60V in the purification zone and increasing the maintenance voltage to 48V/60V. It helps to maintain the minerals in purified water.
The SWFA-encoded microprocessor unit and logic controlled the unit's process with reference to the storage purification program sequence. SEAD voltage control and the purification program independently performed the purification process.
Second method: At the specific time of the purification zone cycle, the input voltage to the SEAD is switched off, i.e., at the sequence of Reversed Positive Polarized adsorption phase. This maintains the mineral level in the output water.
Considered Purified Tank: 5L Voltage to the SEAD Tank TDS, PPM Cycle (Desorption + Adsorption) Time
Input Water TDS
Filling Cycle Desorption Phase Adsorption Phase No. of Cycle
<200 PPM Tank Filling Part 1 Part 2
1L 0V -48V/60V *48V/60V 0V 1 <200 One full cycle 4min; In each one cycle approximately 800ml to 1000ml of water filling in the Purification Tank.
2L 0V -48V/60V 0V +48V/60V 2 <200
3L 0V -48V/60V +48V/60V +48V/60V 3 <200
4L 0V -48V/60V 0V 0V 4 <200
5L 0V -48V/60V 0V +48V/60V 5 <200
b. Input Water Greater than 200 – 2000 PPM:
In this case, Sensepure senses the input water TDS and maintains the SEAD input voltage 48V/60V throughout the purification zone sequence. SWFA encoded microprocessor unit & logic controlled the process of the unit with reference to the storage purification program sequence. SEAD voltage controlling, and purification program independently performs the purification process.
In two case a & b category, Sensepure sensor will decode the input water TDS continuously and send the decoded date to micro controller. Micro controller will control the entire process and process explained.
4.2 SensePure Water Quality Conductivity sensor in the purified water storage container/tank:
In this sequence, the water quality sensor is immersed in the purification tank, and the TDS level of the purified tank is always sensed. As the unit starts as per the pre-programmed SWFA encoded microprocessor logic, purified water begins filling the purified water storage container and, simultaneously, water contact with the Senspure sensor. If the water TDS is less than pre stored value (for example <20PPM ± 10), the sensor provides the signal to the SWFA microprocessor to control the SEAD input voltage (Shut down or reduce the input voltage ) in the respective adsorption cycle, so there is no high TDS reduction, and the unit works as a UV purifier. When the TDS of the purified tank is> 20PPM±10, the sensor provides the signal to the SWFA microprocessor to switch on the input voltage to SEAD, which leads to the TDS reduction. This voltage regulation with purification continues as the purification tank gets filled. The sensor always senses the water quality, compares it with the stored TDS value, and decides the program logic using voltage control.

d) At specified intervals at T1 terminals (Anion Exchange side of carbon –graphite cell) -vDC voltage applied & T2 Terminal (Cation Exchange side of carbon-graphite cell) +vDC voltage applied: Desorption begins.
e) At that time, Valve 1, and Valve 2 & Pump open & water filling to the SEAD.
f) The minimum time required for the phase is 10 Sec.
Step 2: Direct polarized desorption phase or -Ve Terminal on SEAD - section 1 & 2
a) T1 Terminal (Anion Exchange side of carbon -graphite cell) is -vDC & T2 Terminal (Cation Exchange side of carbon -graphite cell) +VDC; Desorption of the ion from the carbon-graphite cell takes place.
b) The surface adsorbed +ve & -ve ions penetrate into the pre-treated source water & mineral SEAD cavity source water increase.
c) At this phase -section 1 solenoid Valve V1, V2, V3, V4, V5, V6, V7 & Pump are off for the specific time interval.
d) At this phase, in the section 2 solenoid valves V1, V2, and V3 and the Pump are ON, allowing the high TDS water in SEAD module to be removed from the cell through the drain line by Solenoid valve V3.

b) Specified time intervals in the zero-voltage phase help facilitate the fast peak voltage up in the cell membrane at the positive adoption zone.
c) In section 1, all valves and pumps are off for a certain time (5 Sec is minimum). In Section 2, Solenoid Valves V1, V2, and V3 and the pump are open, the pretreated water entered in to the SEAD module and which helps drain out the high TDS water of the previous phase from the SEAD module & tube. Which help to avoid the cross -mixing of water in the next step (4).
Step 4: Reversed Positive Polarized adsorption phase or +Ve Terminal on SEAD - Section 1, Section 2 & Section 3
a) T1 Terminal (Anion Exchange side of carbon -graphite cell) is +vDC & T2 Terminal (Cation Exchange side of carbon-graphite cell) is -vDC. Adsorption of -ve & +ve ions in the water into the carbon-graphite cell takes place. The input water TDS reduction & inorganic contaminants adsorbed on the surface of the cell.
