Wastewater treatment technology in electronic components manufacturing industry

Electronic components are parts of electronic devices used in home and industry

To meet the current demand for electronic devices, many companies producing electronic components have been built. In addition to developing the electronic components manufacturing industry, it is necessary to improve waste and wastewater treatment technology from the electronics manufacturing industry. So what is the technology for wastewater treatment in the electronic components manufacturing industry? What is the wastewater treatment process?

What is wastewater treatment technology in the electronic components manufacturing industry?

Wastewater in the electronic components manufacturing industry includes:
▶Domestic wastewater: Wastewater from workers' daily activities such as eating, drinking, cleaning... Wastewater includes many components such as garbage, leftover food, grease in food...

▶Production wastewater: Contains heavy metals such as:

▶Mercury: Directly affects the central nervous system, digestive system and immunity in the human body. If you inhale too much mercury vapor over a long period of time, there is a risk of death

▶Arsenic: Even a small amount of arsenic, if exposed daily, can have negative effects on the body, causing skin ulcers, affecting the heart, and more dangerously can lead to cancer.

▶Lead: Lead poisoning can cause brain defects in children. If pregnant women are exposed to lead, it can lead to miscarriage and premature birth

▶Chromium: The first harmful effect that can be mentioned is the impact on the human respiratory system. More severe cases can lead to death

▶Cadmium: Considered the metal that causes the most serious effects on humans. Affects the development of bones and joints

In addition, there are many other metals mixed in wastewater during the production of electronic components

Wastewater treatment in the electronic components manufacturing industry applies technology to filter wastewater, separate impurities, waste, and heavy metals to create clean water that does not pollute the environment.

Wastewater treatment process in electronic components manufacturing industry

Unlike wastewater from the food processing industry and confectionery production using biotechnology, to treat wastewater from the electronic components manufacturing industry, it is necessary to use physicochemical measures as follows:

▶Collection pit: Wastewater is directed through screens to remove all large-sized trash and leads into the collection pit. Septic tanks are often designed to be large and deep to be able to hold a lot of wastewater at the same time

▶Regulation tank: Used to regulate water flow, here, wastewater is continuously mixed and sent to flocculation tank

▶Flocculation tank: To treat wastewater, in this tank people combine two methods: chemical and mechanical. Along with the chemical filling system, a quantity of aluminum alum is pumped into the tank, removing residues in the tank. The flocculation process helps break the stable state of candy particles. And the flocculation process binds the colloidal particles into a larger mass for easy separation.

After completing the flocculation and flocculation process, the water is led through the sedimentation tank

▶Settlement tank: The flocs linked in the flocculation tank will settle to the bottom of the wastewater. The water above will be pumped to the Anoxic aerobic tank

▶Anoxic aerobic biological tank: Under the influence of aerobic organisms, nitrogen will be separated, leaving water containing mud. The water mixture containing sludge continues to be pumped to the Aerotank

▶Aerotank: Thanks to 2 air blowers, air is continuously supplied. Under the influence of microorganisms in the aeration tank, the microbial sludge will settle to the bottom of the tank, and the sludge-cleaned water will be transferred to the disinfection tank.

▶Disinfection tank: Bacteria remaining in the water under the effect of the disinfection tank will be completely cleaned. The cleaned water will be pumped to the pressure filter tank

▶Pressure filter tank: This is the final stage of the wastewater treatment process, where microscopic dirt is treated. The pressure filter tank is also responsible for cleaning filter materials. Water after cleaning will be released into the environment

Advantages of electronics industry wastewater treatment technology

Wastewater treatment technology in the electronic components manufacturing industry has many advantages, the most prominent of which are some of the following:

Completely treats excess heavy metals in the field of electronic components production, bringing clean water into the environment, without causing harm to the health of users.
Eliminate waste from workers' daily activities, protect the water environment and microorganisms living in water
