Pretratamiento y depuraci\u00f3n de equipos de \u00f3smosis inversa<\/strong><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

The quality of pretreatment is the key to the stable operation of reverse osmosis equipment<\/a>. When the water inlet of reverse osmosis equipment is groundwater, there is no problem with the pretreatment of quartz sand and activated carbon, but it is different when using surface water.<\/p>\n

1. Reverse osmosis equipment pretreatment reagents. The reagents used in the treatment include coagulants, flocculants, oxidants, reductants, scale inhibitors, etc., especially coagulants and scale inhibitors. The selection, dosage and even the method of drug preparation of these reagents will have a great impact on the operation of reverse osmosis.<\/p>\n

Usually, we will pay attention to the detection of the iron content of the influent water. In fact, the high aluminum content in the influent water will also cause pollution of the reverse osmosis membrane<\/a>. Aluminum pollution of membrane is caused by aluminum hydroxide precipitation. Aluminum hydroxide precipitation usually exists in the form of colloids. It is an amphoteric hydroxide with very low solubility in the pH range of 6.5-6.7. If the aluminum coagulation process is carried out at too high or too low pH, aluminum ions will enter the reverse osmosis device and cause pollution of the reverse osmosis membrane. Therefore, for the pretreatment system using aluminum salt as a coagulant, its pH value is best controlled at 6.5-6.7 to minimize the solubility of aluminum. Pay attention to timely adjust the dosage according to the water quality. If possible, regularly test the aluminum content in the pretreated water and control it below 0.05 mg\/L.
In order to prevent scaling on the concentrated water side, we usually add scale inhibitors. The current scale inhibitors are compounded with some organic acids and organic phosphates to achieve the purpose of scale inhibition and dispersion. If improperly selected or controlled, these organic substances will foul the reverse osmosis membrane<\/a> elements, and it will also become a breeding ground for bacterial microorganisms and bring greater harm to the operation of reverse osmosis.<\/p>\n

2. Temperatura<\/p>\n

Quiz\u00e1 todo el mundo sepa que la temperatura influye mucho en el flujo de los elementos de la membrana de \u00f3smosis inversa. Por lo tanto, al calcular el rendimiento del agua, se debe comprobar la temperatura para compararla. Por lo tanto, en lugares donde la temperatura del agua es baja en invierno, se dise\u00f1ar\u00e1n equipos de calefacci\u00f3n en el sistema de pretratamiento de \u00f3smosis inversa, lo que puede garantizar eficazmente que el equipo de \u00f3smosis inversa tambi\u00e9n pueda alcanzar la salida dise\u00f1ada en invierno.
In fact, the SiO\u2082 precipitation in the membrane element is also closely related to the inlet water temperature of the reverse osmosis device. The silica concentration in the concentrated water cannot exceed 100 mg\/l at 25\u00b0C and cannot exceed 25 mg\/l at 5\u00b0C. Therefore, when there is no heating equipment in the pretreatment system, in winter, it is necessary to pay close attention to the pollution of silica precipitates on the membrane elements, and strictly control the content of silica in the concentrated water, and its value cannot exceed the solubility at that temperature.
Funcionamiento y gesti\u00f3n de equipos de \u00f3smosis inversa
1. Regular inspection of reverse osmosis equipment Regularly inspect and replace the filter element of the safety filter in time to prevent the particle contamination of the reverse osmosis membrane caused by leakage of the filter element due to installation or quality problems. When the inlet pressure difference of the safety filter is greater than 0.15MPa, the filter element should be replaced. Generally, it should be inspected once a month. The filter element should not be used for more than 6 months. During operation, it should also be checked frequently to see if there is enough gas in the safety filter to prevent air from entering.<\/p>\n

The level of operators’ ability depends on whether they can timely discover and correctly deal with defects and hidden dangers in the system, which is an important factor affecting the operation of reverse osmosis equipment. Misoperation by operators is more harmful to the system, and damage to such membrane elements is often irreversible. The flushing work before and after the restart of the reverse osmosis equipment must be done well to prevent residual gas in the equipment from running under high pressure, forming air hammers that will damage the membrane, and the concentration of inorganic salts on the concentrated water side of the membrane is higher than that of the raw water, which is easy to scale and pollute the membrane.<\/p>\n

2. Inspecci\u00f3n de los elementos de la membrana de \u00f3smosis inversa<\/strong><\/span>
(1) Generalmente, cada seis meses (el tiempo se puede acortar si es necesario), se debe inspeccionar cada conjunto de elementos de membrana de primera y segunda etapa de \u00f3smosis inversa.\u00a0<\/p>\n

(2) Abrir la tapa del extremo del recipiente a presi\u00f3n (utilizar herramientas especiales y ser operado por t\u00e9cnicos cualificados).\u00a0<\/p>\n

(3) Compruebe si hay impurezas mec\u00e1nicas, deposici\u00f3n de \u00f3xido met\u00e1lico, crecimiento microbiano bacteriano, cambios de color del elemento de membrana y descamaci\u00f3n de la membrana en la secci\u00f3n de entrada de agua. (4) Si es necesario, se puede extraer el elemento de membrana de \u00f3smosis inversa para realizar una inspecci\u00f3n detallada. Cuando se extrae el elemento de membrana de entrada de agua, no debe extraerse directamente, sino que debe empujarse fuera del recipiente a presi\u00f3n de acuerdo con la direcci\u00f3n del flujo de agua. Lo mismo se aplica a la instalaci\u00f3n.
(5) Despu\u00e9s de cada inspecci\u00f3n, deber\u00e1n elaborarse registros detallados para su comparaci\u00f3n.
3. Calibre cada medidor con regularidad para garantizar la precisi\u00f3n y fiabilidad del instrumento.
4. Analizar y contabilizar peri\u00f3dicamente los datos de funcionamiento del equipo de \u00f3smosis inversa.
La presi\u00f3n de funcionamiento, la tasa de recuperaci\u00f3n (o descarga de agua concentrada), el SDI (\u00edndice de contaminaci\u00f3n) del agua de entrada, el pH, el cloro residual y la temperatura son los principales par\u00e1metros de control de funcionamiento del dispositivo de \u00f3smosis inversa; la tasa de desalinizaci\u00f3n, la producci\u00f3n de agua y la diferencia de presi\u00f3n son los tres principales par\u00e1metros de control del rendimiento. Deben observarse estrictamente en la gesti\u00f3n del funcionamiento, y las condiciones de funcionamiento no deben modificarse a voluntad. En particular, es necesario evitar el aumento de la tasa de recuperaci\u00f3n para aumentar la producci\u00f3n de agua, lo que provocar\u00e1 la formaci\u00f3n de incrustaciones en la superficie de la membrana de \u00f3smosis inversa; evitar el funcionamiento continuado cuando el valor de SDI supere la norma, lo que provocar\u00e1 el bloqueo de la membrana de \u00f3smosis inversa; evitar el funcionamiento continuado por encima de la diferencia de presi\u00f3n m\u00e1xima permitida, lo que provocar\u00e1 da\u00f1os destructivos en el elemento de membrana.<\/p>\n
