The characteristics of reverse osmosis element membrane in the entire daily application process, in addition to all normal declines, are more serious in that it suffers from environmental pollution during the application. Therefore, in order to improve the service life, cleaning on time is very important.
1. Precautions for cleaning reverse osmosis element membrane
①. The pH value of the syrup should be adjusted within the standard range of reverse osmosis element membrane.
②. The water resources used for cleaning applications should be reverse osmosis water production.
③. The cleaning flow rate and membrane loss should be adjusted within the scope of the cleaning standard. In order to better improve the service life of ro membrane element, it is very important to clean filter ro membrane. As the latest industrial production separation unit, membrane separation equipment has long been integrated into various industrial production industries. The cleaning and maintenance of filter ro membrane can ensure its normal operation, increase the service life, and reduce the cost of the product.
2. Common problems of reverse osmosis element membrane cleaning
①. The actual operation of installing reverse osmosis element membrane should use goggles and cut-resistant gloves in a well-ventilated place. Wear protective clothing, etc.
②. When the maintenance fluid splashes into the eyes, slowly wash with cold water for at least 15 minutes, and go to the hospital for outpatient examination and take medical measures as soon as possible.
③. Determine whether the production of drinking water or food meets the water quality testing standards.
④. The food and drug safety application standards must be consulted before work.
The weight of the 5.8 inch film is generally about 16kg, it is easy to hurt the waist when moving, please pay attention.
⑤. In order to increase the service life of ro membrane element, preliminary treatment measures must be made.
⑥. Preparatory treatments such as quartz sand and activated carbon must be washed every day, and the softener should be washed once for 30 minutes each time to avoid the deposition of stains in the water.
⑦. The filter element in the machine also needs to be replaced on time to prevent fine particles from entering the final membrane, causing clogging, pores, increased conductivity, and reduced total flow.
