During operation, the operating conditions of the system, such as pressure, temperature, system recovery rate, and feed water concentration may change, which may cause changes in the flow rate and quality of the produced water. In order to effectively evaluate the performance of the system, it is necessary to compare under the same conditions. The production water flow rate and quality data, because it is impossible to always obtain these data under the same conditions, it is necessary to standardize the RO performance data under the actual operating conditions according to the constant operating conditions in order to evaluate the performance of the RO membrane. Standardization includes the standardization of product water flow and the standardization of salt permeability.
If the operating conditions of the system are the same as the initial operation, the theoretically achievable flow rate is called the standardized flow rate. If the operating conditions of the system are the same as when it was initially put into operation, the theoretically achievable desalination rate is called the standardized desalination rate.
It can be known from the above definition that the standard reference point is the operating data at the initial commissioning (steady operation or after 24 hours), or the standard parameters of the reverse osmosis membrane element manufacturer as a reference. At this time, the reverse osmosis membrane basically has no In the future, if there is any pollution, whether there is pollution in reverse osmosis and whether it needs to be cleaned in the future will need to be judged by the data at the time of initial operation. Therefore, the data at the time of initial operation is particularly important and must be recorded.
The reverse osmosis system must have a complete record of operating data: feed water pressure, intermediate pressure, concentrated water pressure, feed water flow, concentrated water flow, feed water conductivity (or TDS), product water conductivity, concentrated water conductivity (or It is TDS), feed water PH, feed water temperature, feed water ORP. Enter daily operating data into reverse osmosis standardized software. The standardized software can graphically reflect the operating conditions of the system, so that managers can judge whether the system is abnormal, check equipment and adjust parameters in time to avoid accidents.
