In the process of producing high-purity water, the ultrapure water machine will go through a series of water treatment steps, such as reverse osmosis, ion exchange, electrodeionization, etc., to remove ions, microorganisms, and organic substances from the water. During these treatment processes, some impurities in the water will be removed and concentrated in the wastewater.

The main purpose of wastewater discharge is to ensure the stable operation and long-term use of ultrapure water machines, for the following reasons:

Impurity accumulation: Impurities in the water will gradually accumulate in the treatment equipment and filter element of the ultrapure water machine. If not removed in a timely manner, it will reduce the purity and stability of the water quality, and affect subsequent experimental and analytical results.

Prevention of pollution: The removal of impurities in wastewater may contain toxic substances, microorganisms, or organic compounds. If not discharged in a timely manner, it may pose potential risks to the laboratory environment and the health of operators.

Equipment maintenance: Discharging wastewater also helps to protect the equipment and filter element of the ultrapure water machine, preventing impurities from accumulating inside the equipment and affecting its normal operation and lifespan.

Environmental protection: Impurities in ultra pure water machine wastewater may cause pollution to the environment, such as the discharge of harmful substances that may have a negative impact on water sources and soil. By properly treating and discharging wastewater, the impact on the environment can be reduced.

It should be noted that the discharge of wastewater should comply with relevant laws, regulations, and environmental protection requirements. The laboratory should establish corresponding wastewater treatment systems to ensure compliant treatment and safe discharge of wastewater, in order to reduce negative impacts on the environment.
