Biological Filtration Media for Wastewater Treatment is a material used to support the formation and maintenance of biofilms. Its function is to provide an ideal physical carrier for the growth of microorganisms.

Adsorption refers to the process by which one substance attaches to the surface of another substance. Specifically, adsorption uses the surface of porous materials to attract and fix pollutants in water on its surface, thereby separating these pollutants from the water body.

A standard water treatment system usually consists of a pretreatment unit, a core treatment unit, a post-treatment unit, and auxiliary equipment. These parts work together to ensure that the water quality meets the expected standards.

Integrated water treatment machinery, as the name suggests, integrates various functional modules of water treatment into one device or system, and purifies and treats water quality through a combination of multiple treatment processes.

Although household sewage reuse is not yet popular, this trend is gradually emerging, especially in some states with relatively scarce water resources, such as California, Arizona, and Nevada. Household sewage reuse usually includes two aspects: treatment and reuse of gray water and black water.

Sewage treatment plants mainly treat seriously polluted domestic sewage and industrial wastewater, with complex processes and large environmental impacts, while gray water treatment plants focus on treating less polluted gray water, with relatively simple processes and small environmental impacts.

At present, the coagulants used in the market are mainly divided into three categories: inorganic coagulants, organic coagulants and polymer coagulants. Each type of coagulant has its own unique chemical properties and application scenarios.

Sewage recycling is a complex process that requires multiple steps to convert sewage into reusable water resources. Generally speaking, the steps of sewage recycling include: pretreatment, primary treatment, secondary treatment, tertiary treatment (or advanced treatment), disinfection and reuse.

Ultraviolet disinfection technology is widely used in water treatment, mainly including drinking water treatment, sewage treatment, industrial wastewater treatment, aquaculture and swimming pool disinfection.

The main types of water treatment plants are: 1. Drinking water treatment plants, 2. Sewage treatment plants, 3. Industrial water treatment plants, 4. Seawater desalination plants.
