Items to confirm before operating a small reverse osmosis device

  Reverse osmosis, also known as hyperfiltration, is 60 a membrane separation technology developed in the past decades. Due to its characteristics such as material phase change, low energy consumption, simple equipment, normal temperature operation, and strong adaptability, it 40 has been widely used in various fields of the national economy after years of development. Because Small Reverse Osmosis Equipment the process and system control are relatively simple, therefore, it can be easily managed by analyzing and understanding the factors affecting Small Reverse Osmosis Equipment formation. In addition to the performance limitations of the equipment itself, Small Reverse Osmosis Equipment normal operation and maintenance are also important.

  Items to be confirmed before operation

  Before putting Small Reverse Osmosis Equipment into trial operation, it is necessary to confirm whether the pretreatment equipment is operating normally. When the indicators of important water quality analysis items are greater than the corresponding baseline, it is necessary to confirm the status of the raw water through water quality analysis. The specific contents that need to be confirmed before the system operation are as follows:

  1 ）Raw water quality: SDI ，turbidity, temperature, pH ， TDS ，residual chlorine and other basic analysis items.

  2 ）When the system is running, whether the raw water supply can meet the operation of the small reverse osmosis equipment system.

  3 ）Whether the operating status of each pretreatment device in the system meets Small Reverse Osmosis Equipment the operating requirements.

  4 ）Operation and control of the injection amount of each injection device.

  5 ）Calibration and installation status of each measuring instrument, that is, whether it has been correctly calibrated and installed.

  6 ）Setting and status of abnormal high and low pressure protection safety devices (i.e., pressure controllers).

  7 ）Connection position of pipelines and fixing status of reverse osmosis pressure vessels.

  8 ）Reverse osmosis high-pressure pump status.

  9 ）Valves used in the system (permeate water outlet / concentrate water outlet) are suitable for opening and closing.

  10 ）Whether the automatic control system of the small reverse osmosis equipment is working properly.

  11 ）Whether the detection instruments installed in the reverse osmosis system are working properly.
