1 Specifications METHOD AND SYSTEM FOR PRODUCING FRESH WATER FROM SEAWATER Technical Area The invention is suitable for marine vessels, fish farms, coastal businesses, domestic use and industrial water. It is related to the production of fresh water from seawater to meet purification needs. The invention specifically relates to a system and method for producing fresh water from seawater. State of the Art 10 Currently, in existing machines, seawater is drawn in by a suction pump. Water The mixture is passed through 50 micron, 20 micron and 5 micron filters respectively, under high pressure. The water is sent to the pump. The water coming out of the high-pressure pump undergoes reverse osmosis. It passes through the membrane and is transferred to the utility tank. Some manufacturers use high pressure. For safety purposes, a pressure sensor is used and a carbon filter 15 is installed at the inlet of the utility tank. It adds. The pre-filters used in the current system need to be replaced regularly. In some systems, the reverse osmosis membrane is mechanically regulated using fresh water produced by the device. It can be washed manually with the help of a valve. 20 Another technique currently in use is the purification of seawater using reverse osmosis technology. One of the known solutions for this is WO2010010243A1 – “Reverse-Osmosis Water This is described in the patent document titled "Desalination Plant". In this system, the reverse... Osmosis membrane unit, high-pressure pump, pressure, flow rate, temperature and salinity 25 The plant operates using sensors and energy recovery equipment. Automatic control of its parameters is provided. The system is especially important for energy consumption. It focuses on optimizing and ensuring the efficient operation of the reverse osmosis plant. However, the document in question mentions nanofilters in the pre-treatment stage of seawater. its use, the storage of utility water and drinking water in separate lines, product 30 the water is disinfected with UV and ozone, and then re-treated with a mineral filter. depending on whether mineralization is carried out or on data received from water quality sensors a statement regarding stopping production and switching the system to automatic washing mode 2 No explanation is provided. Additionally, there is a remote web-based control and management infrastructure. This has not been discussed in detail. In current technology, seawater and waters with high salinity are treated. One of the solutions for the use of nanofiltration is US11795071B2 – “Multi-Valent 5 In the patent document titled "Ion Concentration Using Multi-Stage Nanofiltration" This document explains how to use multi-stage nanofiltration units. selective separation of specific ions and remineralization of purified water It focuses on the usability of nanofiltration stages and their efficiency. To increase it, recirculation and different feeding strategies are suggested. However, 10 The document describes the nanofilter as a pre-treatment stage before the reverse osmosis membrane. It is used as such, the reverse osmosis outlet pressure is continuously controlled by a motorized automatic valve. when checked, the product water is monitored with quality sensors and when it exceeds the limit the system is automatically shut down and the membranes are put into automatic cleaning mode There is no integrated control architecture through which it is passed. Also, UV-ozone 15 disinfection, dual tank water separation for drinking and other uses, and remote wireless management. Its features are also not described in this document. Early stages of cleaning membrane systems from the previous technique. One of the solutions is US3992301A – “Automatic Flushing System for Membrane 20 The patent titled “Separation Machines Such as Reverse Osmosis Machines” This is explained in the document. In this system, the performance of reverse osmosis membranes... to reduce losses at certain times or under certain conditions Automatic washing and cleaning cycles are applied. Pressure reduction, washing. Cleaning of membranes through processes such as fluid delivery and automatic valve control 25 that is the goal. However, the system in question is only for membrane cleaning. It focuses on its function of producing drinking water from seawater. It does not offer an integrated purification line. Especially considering the data from water quality sensors. Automatic production shutdown based on real-time data, washing water usage. Instead of being sent to the washing line, it is removed via a separate discharge line, washing 30 Afterwards, the system automatically returns to normal operating mode, UV-ozone disinfection, mineralization unit and web-based system via phone / tablet Features such as remote control are not included in this document. Therefore... 3 The document describes the intelligent control, water quality safety, and multi-faceted capabilities offered by the present invention. It does not fully meet the requirements of a phased treatment approach.

It is the method. In the system, seawater is first passed through an automatically washable 50 micron filter (11). Then, with the help of the suction pump (20), the low pressure and flow sensors (30) It passes through and enters the nanofilter (40). Sensors (30) located at the outlet of the nanofilter (40) Pressure and flow rate measurements are taken again. Then a carbon filter (45) is passed through. 7 Afterwards, the water is sent to the high-pressure pump (50). Reverse osmosis (RO) membrane (60) provides the necessary pressure for the filter. The water coming out of the high pressure pump (50) is checked by the sensor (30) Salts and minerals are transferred to the reverse osmosis membrane (60). The reverse osmosis membrane (60) transfers salts and minerals to the reverse osmosis membrane (60). separates. Pressure value at the outlet of reverse osmosis membrane (60), motorized automatic valve (70) The desired work is continuously checked by the software with the help of the software. It is kept under pressure. At the membrane (60) outlet, the flow splits into two. The first flow is the concentrated saline line 10 The second flow is removed from the system by a booster pump (80). The water for use passes through the flow meter (90) and reaches the quality sensor. then UV and ozone units (100) for water, microorganism and bacteria removal Water is passed through. It is placed in two separate tanks: the utility water tank (110) and the drinking water tank (120). It is even directed. The water sent to the drinking water line reaches the reservoir (110) before 15 The water is passed through a mineral filter set (130). If necessary, the waiting water is filtered. UV and ozone units (100) to maintain the quality of drinking water tank (120) It can also be installed inside the utility water tank (110) and the drinking water tank (120). Level control is performed by level sensors (35). During production, the quality sensor (140) detects that the water quality is outside the specified limits. When it detects that it has come out, the control unit with which it is in contact (170) stops the production and This switches the system to automatic washing mode. At this stage, Valve 1 (1) closes and Valve 2 (2) It is opened. Washing water is passed through the pre-pressure pump (150) and sensors (30) It is controlled by. Then Valve 3 (3) closes and Valve 4 (4) opens. Then 25 Valve 2 (2) is closed and Valve 5 (5) is opened to wash the nanofilter (40). Afterwards, Valve 10 (10) is opened and the micron filter (11) at the inlet is washed. After the specified time, the relevant valves change position and Valve 3 (3) and Valve 2 (2) By opening, the high-pressure pump (50) and the reverse osmosis membrane (60) are washed. This process takes 30 minutes. During this process, washing water is not sent to the service line. Valves 4 and in the outlet line Thanks to the positioning of 5 (4, 5), the washing water return line from the system It is discharged outside. 8 The system automatically switches to normal operation when the set washing time is complete. It returns to its previous mode and continues water production. The user can access the system when needed. You can intervene manually. In addition, the system can be accessed via a web-based application on the device's phone or tablet (160) 5 It can be controlled via Wi-Fi or RF communication technologies. It can be monitored and managed remotely using this method. Furthermore, unlike existing systems, it has an automatic washing system and its associated control system. An algorithm has been developed. This structure takes into account inlet and outlet flow rates, pressure values, and water quality. By continuously monitoring the parameters, we can detect any contamination or clogging of the filters. It can perform the washing process automatically when necessary. It can start.
