Self-cleaning filter introduction and purchasing guidance


Self-cleaning filter is a kind of filter that directly intercepts impurities in water, removes suspended solids and particulate matter in water, reduces turbidity, purifies water quality, reduces system dirt, bacteria and algae, rust, etc., to purify water quality and protect other equipment in the system. Working precision equipment, water enters the body of the self-cleaning filter from the water inlet. Due to the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition, and give the signal to the sewage valve to automatically discharge the sewage. From the working form, it can be divided into backwash filter, brush self-cleaning filter, multi-column self-cleaning filter, suction self-cleaning filter and so on.

Self-cleaning filter, operation and control can automatically clean and filter without any external energy source, and automatically discharge sewage. The flow is continuous during backwashing, and the cleaning and filtering cycle can be adjusted. The self-cleaning and filtering time defaults to 10-60/s, and the water loss in cleaning and filtering only accounts for 0.08-0.6% of the filtered water volume; Up to 1.0-1.6Mpa; single unit flow: 4-4160m³/h. It can be installed vertically, horizontally, or upside down in any direction, and can be used for water filtration in various industries such as industry, agriculture, municipal power, electronics, medicine, food, printing and dyeing, construction, steel, metallurgy, and papermaking.

The self-cleaning filter is a precision device that uses the filter to directly intercept impurities, floating objects, particles, etc. in the liquid, while reducing the turbidity of the water, reducing dirt, and at the same time ensuring the normal operation and service life of the subsequent equipment. It has automatic the characteristics of sewage .


Considering these aspects, let you choose a satisfactory self-cleaning filter

1. Selection of filtering precision

The precision determines the type of self-cleaning filter. The filter directly affects the ability of the filter equipment and the filtration precision. The precision range is 5-3000 microns. The smaller the precision, the better the water quality. Users can choose according to the actual situation on site, or we can choose Contact relevant personnel for communication selection.

2. The amount of filtered water

The filtered water volume determines the size of the equipment. The larger the water volume, the larger the equipment required. The range of the filtered water volume can be calculated in hours, and the size range of the equipment diameter can also be selected according to the actual situation. In some cases, it can be customized.

3. System pressure

During the operation of the self-cleaning filter, it needs to withstand the pressure from the system operation. Please inform our staff in advance before selecting the type. The normal pressure range is 0.1-1.6Mpa. (can be customized according to the situation)

4. Equipment material

Equipment cleaning components (including filters and brushes) are made of stainless steel. The self-cleaning filter housing is made of carbon steel and stainless steel for users to choose. If the filter stock solution is not corrosive, the material requirements for the filter should not be too high. Otherwise, the cost is high, and carbon steel can be selected at this time. However, in the paper industry, stainless steel is generally used due to the high corrosion resistance of the filter.
