What are the reasons for the decline in water production capacity of water treatment equipment?

The main reasons for the decline in the water production capacity of water treatment equipment are as follows: 1. The reduction in the number of membrane modules. 2. The membrane modules should be compacted in accordance with the designed number of membrane modules. When operating under conditions far exceeding the reference pressure, the membrane module will become compacted. Replace the membrane module. 3. Operate under conditions of higher recovery rate. When operating under a recovery rate of over 75%, the volume of concentrated water decreases, which leads to an increase in the water concentration ratio within the membrane module. As a result, the quality of the feed water deteriorates significantly. Due to the increase in osmotic pressure of this feed water, the permeation volume decreases. In severe cases, salt scale will precipitate on the membrane surface. 4. During operation, the pressure difference of the reverse osmosis device rises according to the designed recovery rate of water production. Improve the operation and management of the pretreatment device, improve the reverse osmosis water quality, and use

The reasons for the increase in the conductivity of purified water

1. Scaling pollution: excessively high recovery rate, deteriorating water quality, poor quality of scale inhibitor, unreliable addition of scale inhibitor, etc. 2. Leakage of connecting parts: O-ring leakage, leakage of connecting parts. 3. Temperature rise: salt permeability increases as temperature rises. 4. Increase in influent conductivity: The increase in influent conductivity directly leads to an increase in the conductivity of the produced water, errors in conductivity meters, etc. 5. Increase in recovery rate 6. Reduced operating pressure: Lower operating pressure can cause an increase in conductivity, such as temperature rise, which does not require a higher operating pressure. 7. Reduced membrane element performance: Membrane element scratches, membrane oxidation, chemical cleaning damage, etc. 8. Organic contamination: Pollution, colloid pollution, insoluble NOM pollution, organic matter pollution, etc. 9. Abnormal PH value: The PH value is too high

The working principle and function of water softening equipment

The working principle of water softening equipment: The hardness of water is mainly composed of cations in it: calcium (Ca2+) and magnesium (Mg2+) ions. When the raw water with hardness passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are adsorbed by the resin, while sodium ions are released. Thus, the water flowing out of the exchanger is softened water with the hardness ions removed. When the resin adsorbs calcium and magnesium ions to a certain saturation, the hardness of the effluent increases. At this point, the soft water equipment will automatically carry out the regeneration work of the exhausted resin according to the preset program. By passing a higher concentration of sodium chloride solution (brine) through the resin, the exhausted resin will be restored to the sodium type resin. The function of softened water produced by softened water equipment: Softened water reduces or avoids the formation of scale and is suitable for washing and bathing. In addition, it also avoids water in the pipes

What is the code for resistivity?

What is the code for resistivity? When determining the electrical conductivity of water, it is related to the size of the water's resistance value. A large resistance value indicates poor electrical conductivity, while a small resistance value suggests good electrical conductivity. According to Ohm's Law, when the water temperature is constant, the resistance value R of water is inversely proportional to the vertical cross-sectional area F of the electrode and directly proportional to the distance L between the electrodes, as shown in the following formula: R=ρ. In the L/F formula, ρ represents resistivity, or specific cathode. The unit of the cathode is the ohm (Ω, code: Ω), or microohm (μΩ), with 1Ω equal to 106μΩ. The unit of resistivity (SI) is the ohm (Ω · m). If the cross-sectional area F of the electrode is made as 1cm ² and the distance L between the two electrodes is 1cm, then the resistance value is equal to the resistivity. The resistivity of water

Common faults of water softening equipment

The reason why the water softening equipment does not produce soft water: The bypass valve is not opened. Solution: Open the bypass valve. Resin leakage. Solution: Check whether the resin tank is damaged to ensure its integrity. Solution for insufficient salt in the salt tank: Check if there is enough salt in the salt tank and add salt to the severe case. Solution to resin failure: Resin failure may be caused by regeneration failure. Regenerate the resin again. Cause of low water pressure: Clogged inlet pipe. Solution: Clean and unclog the inlet pipe or replace it. Solution for a broken water pipe: Inspect the water pipe and replace the broken one. Solution to water valve leakage: Check the water valve to ensure it is functioning properly to prevent leakage from affecting water pressure. The water softening equipment is not in operation

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.
