The filter plates in the multi-plate filter are tightly compacted and stacked within the unit, with the grooves between the upper and lower layers of plates acting as a filtration barrier. Zhejiang's multi-plate filter is a type of self-cleaning filter, employing multiple technologies for safer, more water-efficient, space-saving installation and reduced maintenance. The filter element has a springless design; during filtration, the incoming water pressure cleverly compresses the plate assembly, significantly reducing the backwashing pressure requirement. Impurities of a certain size can enter the interconnected curved ridges along the annular ridges, while larger impurities are intercepted.
The unique structure of the filter plates in the multi-plate filter also simplifies and facilitates the backwashing process of flushing out contaminants, eliminating the need for complex motors and actuators. Simple water flow is sufficient to flush out contaminants from the filter element. This excellent performance reduces the backwashing time of the filter; simultaneously, since contaminants are not only stored between the filter plate assembly and the housing but also, more significantly, within the filter plate assembly, the filter can accommodate a larger volume of contaminants.
I. Introduction to Multi-plate Filters
The multi-plate filter is a recently developed new type of filter. Its filtering element consists of a set of compressed annular plates with micro-fine flow channels. Water passes through the small flow channels between the plates, while impurities are intercepted around and between the plates. An offset inlet and outlet design creates a centrifugal flow, extending the cleaning cycle of the filter equipment.
II. Features of Multi-plate Filters:
The disc filter allows for large-area, long-term filtration, has high pressure resistance, and can filter large amounts of impurities and contaminants, ensuring filtration effectiveness. It is reliable, durable, easy to clean, simple to operate, and requires no special tools. It is resistant to corrosion from various pesticides and fertilizers.
III. Applications of Multi-plate Filters:
1. Direct filtration: Water sources with good water quality and small impurities: Suitable for agriculture, landscaping, and golf courses; drip irrigation and spray irrigation.
2. Secondary protection: Protection against residue after sand and gravel media filters and centrifugal sand and gravel separators.
3. Water treatment, municipal water supply, waterworks, and filters for chemical solutions in industrial and civil construction or factories.
IV. Advantages of Multi-plate Filters:
1. Stable filtration effect;
2. Deep filtration, outstanding dirt-holding capacity;
3. Self-cleaning filter, simple operation, and convenient maintenance;
4. Low system operating cost, reliable performance, and a lifespan of up to 10 years
5. Tank material: Carbon steel
6. Filter media: Quartz sand
7. Filtration accuracy: Primary filtration, 80 mesh (quartz sand size selection 6-8mm)
Greenhouse drip irrigation 3-inch automatic backwashing filter 90 automatic backwashing filter——In the design and installation of greenhouse spray and drip irrigation projects, the head filtration system equipment generally includes centrifugal mesh filters, sand filters, and multi-plate filters. Among them, the fully automatic backwashing multi-plate filter and sand filter are commonly used combinations. Common combinations for 3-inch multi-plate filters include 3-inch 2-unit, 3-inch 3-unit, 3-inch 4-unit, etc.
3-inch 3-unit fully automatic backwashing multi-plate filter:
The multi-plate filter core consists of a set of plates with grooves on both sides. The intersection points of the groove ridges can intercept solid matter in the water. Due to the simultaneous surface interception and coagulation effects, the filtration efficiency is greatly improved. Simultaneously, because the multi-plate filtration system features backwashing, fully automatic continuous operation, low self-water consumption, small footprint, and reliable operation, the backwashing process of the filtration system is carried out alternately, automatically switching between working and backwashing states.
When selecting a filter, please consider the following factors
1. Water treatment capacity
2. System pipe pressure
3. Required filtration accuracy
4. Concentration of suspended solids in filtered impurities
5. Relevant physical and chemical properties of the filter media
6. Special purpose filters
7. Raw water quality and the required accuracy after filtration, as well as the water production per hour, are the basis for selecting our filtration system.
Irrigation fully automatic backwashing multi-plate filter accuracy Multi-plate filter combination——In the design and installation of agricultural drip and spray irrigation systems, fully automatic backwashing multi-plate filters are also called automatic backwashing filters, fully automatic multi-plate disc filters, disc automatic backwashing filters, fully automatic self-cleaning filters, etc. Our company, Yibiyuan Water-saving Equipment Technology Co., Ltd., is a professional manufacturer, designer, installer, and contractor of spray and drip irrigation automatic backwashing multi-plate filters. Common models of this multi-plate filter are 2-inch, 3-inch, and 4-inch. In practical applications, there are various combinations, commonly including single, double, triple, quadruple, and quintuple units. The specific combination method needs to be determined by technical personnel based on the specific situation.
