40T/H large-scale reverse osmosis system device

140T/HCommon steps in the design of large-scale reverse osmosis system devices,Generally speaking, the design of large-scale reverse osmosis membrane systems follows the following methods and procedures:

1) In selectingreverse osmosis membraneWhen designing a reverse osmosis device, the first step is to optimize the design based on the design software provided by the reverse osmosis membrane manufacturer, and then combine the characteristics of the raw water source and the SDI test values of the feedwater to determine the optimal designRO membraneSelection and quantity.

2) In addition, after selecting the type and specifications of the membrane elements used in the system, the required number of membrane elements for the system is obtained by dividing the water production of the system unit by the operating water production of the selected membrane elements. Then, the number of membrane elements that can be embedded in the reverse osmosis container is determined based on the equipment space limitations and external dimensions requirements, and the number of reverse osmosis pressure vessels is determined.

3) Based on the total number of membrane components (i.e. reverse osmosis pressure vessels), arrange them preliminarily according to the principle that the ratio of the two pressure vessels before and after is slightly less than 2:1, and then use the membrane manufacturer's providedcounter-infiltration systemDesign software to confirm the arrangement of membrane components, membrane element models, product water flow rate, water recovery rate, system feedwater pressure, concentrate pressure, membrane element pressure drop, feedwater osmotic pressure, and verify whether various insoluble substance saturation, LSI or S&DSI values, and product water quality data in the concentrate system meet the design requirements.

II40T/HKey points to note in the process structure design of large-scale reverse osmosis system equipment:

largeReverse osmosis deviceThe components of the reverse osmosis pressure vessel should be separately supported on stainless steel brackets, and the height of the pressure vessel arrangement should be convenient for loading and unloading membrane components. In the design of a 40T/H large-scale reverse osmosis system device, a pressure vessel equipped with 8 8040 membrane elements is generally selected because we should consider the pressure that the reverse osmosis equipment can withstand during operation during design. Therefore, when fixing the components and pipelines of the reverse osmosis device, attention should be paid to not limiting themReverse osmosis pressure vesselNormal expansion, otherwise it will cause deformation of the pressure vessel. Once the pressure vessel deforms, it may cause leakage of the U-shaped sealing ring of the built-in membrane element, resulting in channel flow and sealing leakage of the O-ring in the connecting piece of the membrane element. The layout of the pipelines, valves, and instruments of the reverse osmosis system should be easy to operate and adjust. During the operation of a reverse osmosis device, it is crucial to control the system's water production and recovery rate, which rely on the flow meters installed in the system for measurement. Therefore, when designing the device, priority should be given to selecting flow meters with superior and reliable performance. Additionally, the flow meters should be calibrated before installation and use.
