Shenzhen Hongjie Water Technology Co., Ltd. produces pure water equipment, ultra pure water equipment and reverse osmosis pure water engineering installation and commissioning Pollution analysis of nanofiltration membrane in operation Microbial contamination Microorganisms include bacteria, algae...

Polyacrylamide (PAM) is a linear water-soluble polymer. It is the most commonly used water treatment agent in our sewage treatment. There is no one! In our practical application, PAM is divided into three types: cationic, anionic and non-ionic. How to choose these three types of PAM should start fro...

Runxin control valve is the first multi-functional control valve for fully automatic water treatment system with independent intellectual property rights in China. Relying on the principle of face seal, multiple valves are closely integrated on one valve body in a plane circumferential arrangement. ...

Major projects in Dongguan started in the first quarter of 2022 It is a practical action to implement the objectives of economic development It is a powerful guarantee for the steady growth of fixed asset investment in the first quarter It is also an important measure to accelerate high-quality d...

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...
