Description

Parallel water inlet two-stage disc filter

Technical field

The invention relates to a parallel water inlet two-stage disc filter, which belongs to the technical field of water treatment.

Background technique

Water treatment methods include physical treatment and chemical treatment. The way humans treat water has a history of many years. Chemical methods use various chemicals to convert impurities in water into substances that are less harmful to the human body, or to concentrate impurities. The oldest chemical treatment method should be considered to be used. After alum is added to the water, after the impurities in the water gather, the volume becomes larger, and the impurities can be removed by filtration. The physical methods include the use of various filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude impurities in the water. The more important adsorption method is to use activated carbon for adsorption, and the barrier method is to pass water through the filter media to allow the volume Larger impurities cannot pass through, and cleaner water is obtained. The traditional filtration with filter materials is that the water flow directly penetrates through the filter element to obtain purified water, which often requires a large water pressure, and the filtration speed is slow, and the efficiency is low.
