In order to prevent the growth of organisms on the membrane surface during storage and the degradation of performance in subsequent operations, the membrane elements must be stored in a special solution. New module: (1) The membrane components have been tested with water before leaving the factory...

1、 Water inlet solenoid valve The pressure range of inlet solenoid valve is 0 --- 10kg / cm2. Its main function is to automatically cut off the path between raw water and membrane when the equipment is shut down, so as to stop water flow. 2、 Raw water pressure gauge The pressure range is about 3k...

The protection measures of ultra pure water equipment vary slightly according to different parts. Different configurations have corresponding protection measures. Today we will learn about these protection measures that are very necessary to collect. 1. After using the ultra pure water equipment fo...

How to treat water? This paper introduces a professional knowledge of sewage treatment - industrial application and market demand of secondary reverse osmosis + EDI water treatment and EDI deionized water equipment. 1、 Multi media filtration The main task of this stage is to roughly filter the ta...

preface Reverse osmosis, also known as reverse osmosis, is a membrane separation operation driven by pressure difference to separate solvent from solution. Because it is opposite to the direction of natural infiltration, it is called reverse osmosis. Faults caused by poor inlet water quality In t...

Discussion on resource recovery and utilization of reverse osmosis concentrated water 1. Basic information The wastewater is concentrated brine discharged from the primary reverse osmosis desalination unit. Concentrated water will be produced during the preparation of pure water by reverse osmosis...

The reverse osmosis water treatment equipment is divided into two parts, one is the pretreatment commissioning, and the other is the commissioning of the reverse osmosis host. The pretreatment is mainly the positive and negative washing of quartz sand and activated carbon to wash away the fine sand,...

As a deep filtration means, the surface of reverse osmosis membrane element will inevitably remain colloids, microorganisms, impurity particles and insoluble salts on its surface. Therefore, once put into use, the reverse osmosis devices used in many fields will eventually need to be cleaned, but th...

2021 is both a "resource utilization year" and a "low-carbon development year" for the sewage treatment industry During the "14th five year plan" period, sewage treatment and resource utilization were steadily promoted. The county's sewage treatment, urban sludge disposal and reclaimed water us...

Standard recovery rate, actual recovery rate and system recovery rate (1) Standard recovery rate of membrane element: the recovery rate adopted by the manufacturer under standard conditions. (the recovery rate of brackish water is 15%, and that of seawater is 10%) Actual recovery rate of membrane ...

As a deep filtration means, the surface of reverse osmosis membrane element will inevitably remain colloids, microorganisms, impurity particles and insoluble salts on its surface. Therefore, once put into use, the reverse osmosis devices used in many fields will eventually need to be cleaned, but th...

I What is a water hammer? Water hammer is called water hammer because of the inertia of pressure water flow when the power is suddenly cut off or the valve is closed too fast, which produces water flow shock wave, just like a hammer hitting. The water hammer of pump station includes starting water...
