Media Filtration System
25m3/H fully automatic fiberglass medium filter
Equipment Introduction
Medium filter is a kind of filter medium to remove the suspended matter in the water, microorganisms, and other fine particles, and ultimately to reduce water turbidity, purification of water quality effect of a high efficiency filtration equipment. Commonly used filter media are quartz sand, active carbon, anthracite, manganese sand and so on.
Media filter can use a single medium, can also be used according to different needs of a variety of media. Single medium filter is also called shallow medium filter, its main filter medium is generally quartz sand, granite and volcanic gravel, etc.. Multilayer media filter is also called deep media filter, its filter media is composed of more than one kind of filter media, general quartz sand, active carbon, anthracite, manganese sand and other contact media.
Equipment Classification
According to the classification of filtering materials: According to the different filtering materials used, media filters can be divided into multi media filters, activated carbon filters, quartz sand filters, ceramic filters, etc.
Classification based on filtration accuracy: According to different filtration accuracy, medium filters can be divided into coarse filters, medium efficiency filters, high-efficiency filters, etc.
Classification based on working pressure: According to different working pressures, medium filters can be divided into atmospheric filters and pressure reducing filters.
Principle
Its working principle is to use the pores of the filter material, the mud and sand in the raw water, colloid, suspended matter and other impurities. Due to the scientific distribution of the filter material, the filter bed has a good effect on the interception of impurities, and the quality of water is greatly improved. The filtration accuracy of the filter is up to 10μm.
At the same time, the filter bed is gradually intercepted impurities in the water, so that the tank in each layer of the filter material will be fully uniform use, effective filter height, thus extending the service cycle of the filter material, reduce the operation cost of equipment (reduce the number of backwashing and backwashing water consumption).
Equipment Composition
The medium filter is divided into filter system and control system. Filtration system is usually composed of high efficiency filtration unit, three-way automatic valve, inlet and outlet water pipe, sewage pipe. The high efficiency filter unit includes various filter media. The control system is usually composed of PLC timing controller, differential pressure controller, electromagnetic three-way valve and control pipeline.
Characteristics Of The Equipment
1. High filtration accuracy: Medium filters usually have high filtration accuracy, which can effectively remove various suspended solids, organic matter, heavy metal ions and other harmful substances in water.
2. Large filtration area: The filtration area of medium filters is usually large, which helps to improve filtration efficiency.
3. Low operating pressure loss: The pressure loss of the medium filter during operation is relatively small, which is beneficial for extending the service life of the filter.
4. Diversified control methods: The control methods of medium filters are diverse, including automatic control, pressure difference control, manual control, etc., which helps to meet the needs of different water quality and users.
5. Convenient maintenance: The maintenance of media filters is relatively convenient, with maintenance stations generally set up to facilitate the replacement of filter media. This helps to reduce maintenance costs and downtime.
6. Layered filtration and step-by-step cleaning: The medium filter adopts a layered filtration and step-by-step cleaning method, which helps to improve the filtering effect and extend the service life of the filter.
7. Efficient and Durable Filter Media: Media filters are manufactured using efficient and durable filter materials, which have a longer service life and lower costs.
8. Reliable control system: The medium filter control system has functions such as operating status output and fault alarm output, ensuring the safety and reliability of the equipment in use.
9. Can achieve local and remote control functions: The media filter can achieve local and remote control functions, which helps to improve production efficiency and management level.
10. Good universality: The connection method of the medium filter is flange connection, generally using national standard flanges, which has strong universality and helps to simplify installation and maintenance work.
