Fully Automatic Water Treatment with Softening First Level Reverse Osmosis Pure Water Equipment

Product description

Equipment Overview
The “fully automatic softening first level reverse osmosis pure water equipment” is a highly integrated and automated water treatment device designed to convert raw water into high-purity pure water that meets specific standards through a series of professional treatment processes. It combines ion exchange softening technology and reverse osmosis membrane separation technology, and is widely used in industries that require extremely high water quality, such as electronics, pharmaceuticals, food and beverage, etc.
Core components and working principle
Fully Automatic Softening Unit
Function: The main function is to remove calcium (Ca ² ⁺) and magnesium (Mg ² ⁺) ions from raw water, reduce water hardness, prevent subsequent scaling of reverse osmosis membrane components, thereby extending the service life of the membrane and ensuring its efficient operation.
Working principle: Ion exchange resin (such as sodium type strong acidic cation exchange resin, R-Na) is usually used. When raw water passes through the resin layer, calcium and magnesium ions in the water exchange with sodium ions on the resin. Calcium and magnesium ions are adsorbed on the resin, while sodium ions enter the water. The reaction equation is: 2R – Na+Ca ² ⁺=R ₂ – Ca+2Na ⁺, 2R – Na+Mg ² ⁺=R ₂ – Mg+2Na ⁺. When the resin adsorbs calcium and magnesium ions to saturation, it needs to be regenerated with a certain concentration of sodium chloride (NaCl) solution to restore the resin’s exchange capacity. The regeneration reaction equation is reversed from the above exchange reaction.
Parameters: The exchange capacity of the resin is generally between 1.8-2.0 mol/L, and the regenerated salt consumption is about 80-100 g/L of resin. It can reduce the hardness of the raw water (calculated as calcium carbonate) from a few hundred mg/L to below 5 mg/L.
First Level Reverse Osmosis Unit
Function: It is a key step in achieving deep desalination of equipment. Under pressure, it can effectively intercept dissolved salts, bacteria, viruses, small molecule organic matter and other impurities in water, producing high-purity pure water.
Working principle: The pore size of the reverse osmosis membrane is extremely small, about 0.0001 μ m, allowing only water molecules to pass through. The high-pressure pump pressurizes the softened raw water to 0.8-1.5MPa. Driven by pressure, the raw water passes through the reverse osmosis membrane, and water molecules pass through the membrane to produce water (pure water), while concentrated salts, impurities, etc. are discharged as concentrated water. Through this membrane separation process, effective separation of water and impurities has been achieved.

Parameters: The desalination rate of reverse osmosis membrane is usually ≥ 95%, and the recovery rate is generally between 60-80%. For example, when the total dissolved solids (TDS) of the raw water is 1000mg/L, the TDS of the produced water can be reduced to below 50mg/L, and the conductivity can be as low as 5-50 μ S/cm.
Fully Automatic Control System
Function: Fully monitor and automate the operation of the entire device to ensure stable and efficient operation, while also having fault diagnosis and alarm functions.
Working principle: Using programmable logic controllers (PLCs) or other advanced control systems, real-time data is collected through sensors installed at key locations (such as pressure sensors, flow sensors, conductivity sensors, etc.). According to preset parameters and logic programs, automatically control the regeneration of the softening device, the start stop and flushing of the reverse osmosis device, and the opening and closing of various valves. For example, when the softened resin reaches saturation or the water conductivity of the reverse osmosis membrane exceeds the standard, the system automatically triggers the corresponding regeneration or flushing program.

Maintenance and Precautions
Regular maintenance
Softening device: Regularly check the exchange capacity of the resin, generally conducting a comprehensive test every 1-2 years. When the resin exchange capacity drops to 70-80% of the initial value, it is necessary to consider regenerating or replacing the resin. At the same time, it is necessary to ensure the quality and concentration of the regenerated salt solution, regularly clean the salt tank, and prevent impurities from blocking the pipeline inside the salt tank.
Reverse osmosis device: Regularly perform chemical cleaning on the reverse osmosis membrane. Depending on the quality of the raw water and the operation of the system, the cleaning cycle is generally 3-12 months. When the water production of the membrane decreases by 10-20%, the desalination rate decreases by 5-10%, or the inlet and outlet pressure difference increases by 15-20%, timely cleaning should be carried out. In addition, regularly check the operation status of high-pressure pumps, valves, instruments and other equipment to ensure the normal operation of the system.
Control system: Regularly check whether the hardware of the control system (such as PLC, sensors, controllers, etc.) is working properly and whether the software programs are running stably. Backup system parameters and programs to prevent abnormal device operation caused by hardware failures or program errors.
precautions
Raw water quality requirements: The equipment has certain requirements for the quality of raw water. Before use, the raw water needs to be tested and analyzed to ensure that it meets the inlet requirements of the equipment. If the turbidity, residual chlorine, hardness and other indicators of the raw water are too high, appropriate pretreatment is needed to protect equipment components and extend their service life.
Operating environment: The equipment should be installed in a dry, well ventilated, and suitable temperature (generally 5-40 ℃) environment, avoiding direct sunlight and humid environments that can cause damage to the equipment. At the same time, it is necessary to ensure that the power supply of the equipment is stable and meets the electrical requirements of the equipment.
