[0002] Water supply equipment is a kind of equipment used to raise water to a certain height to meet water demand. Water supply equipment can be classified in different ways, for example, according to its use, it can be divided into fire water supply equipment, domestic water supply equipment, production water supply equipment and sewage treatment water supply equipment.

[0003] There are different standards of sanitary requirements for the water bodies supplied by water supply equipment for different purposes. In order to meet the required sanitary requirements for the water supply, it is necessary to filter and purify the water supply.
