Problems solved by technology

In performance estimation, there is an estimation coefficient, which is obtained from experience. However, the water environment and application scenarios in various places are very different. It is impossible to accurately estimate the performance of RO with approximately the same estimation coefficient. When it is too large, it may lead to premature prompting of the scrapping of the RO membrane in use, resulting in waste of cost, or too late prompting of the scrapping time, resulting in poor water treatment efficiency. In either case, it will obviously cause huge losses to water treatment manufacturers
[0006] The estimation method used by the existing domestic water treatment manufacturers is to use the estimation formula and estimation coefficient imported from abroad. Because the water quality in foreign countries is very different from that in my country, the estimation results are also very inaccurate. At the same time, due to the vast territory of our country , the raw water quality and water treatment requirements are not the same everywhere, so how to accurately estimate the performance of RO membrane has become a major problem in the domestic water treatment field

Abstract

The invention relates to the field of water treatment, and discloses a performance estimation method and a performance estimation system for an RO membrane. The performance estimation method for the RO membrane comprises the following steps of collecting basic index data from a collection section and a calibration section separately, wherein the collection section and the calibration section refer to time segments in the use process of the reverse osmosis (RO) membrane, and the basic index comprises feed-water temperature, feed-water salt concentration, fresh water salt concentration and the like; enabling the data collected in the collection section to be compared with performance data obtained by estimation through an estimation coefficient, and adjusting the estimation coefficient according to a comparison result to obtain an adjusted estimation coefficient; and performing verification on the adjusted estimation coefficient through the data collected in the calibration section, and if the verification is successful, performing performance estimation on the RO film by replacing the estimation coefficient before adjustment with the adjusted estimation coefficient. By adoption of the performance estimation method for the RO membrane provided by the embodiment of the invention, the estimation coefficient of the RO membrane can better satisfy local application scenarios, so that the performance estimation accuracy of the RO membrane is improved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a method for estimating the performance of RO membranes and a system for estimating the performance thereof. Background technique [0002] RO is the abbreviation of Reverse Osmosis in English, and it means reverse osmosis in Chinese. Generally, the flow mode of the solvent is from low concentration to high concentration. When the applied pressure is higher than the osmotic pressure, the solvent will flow from high concentration to low concentration, which is the so-called reverse osmosis principle. [0003] RO reverse osmosis technology is a membrane separation and filtration technology powered by osmotic pressure difference. It originated from the research of aerospace technology in the United States in the 1960s and was gradually transformed into civilian use. At present, it has been widely used in scientific research, medicine, food, beverage, seawater desalination etc. [000...
