What does Water Treatment 2 (WT2) primarily utilize for achieving disinfection?

Water Treatment 2 (WT2) primarily utilizes chemical feed for achieving disinfection due to the effectiveness of chemicals in eliminating pathogens and bacteria from water. This method involves the careful addition of disinfectants, such as chlorine, chloramines, ozone, or other chemicals designed for disinfection. Chemical feed systems can be precisely controlled to ensure that the correct dosage is delivered, allowing operators to adjust the treatment based on water quality and specific pathogen challenges.

In WT2 systems, relying on chemical feed means that operators can effectively manage water safety and compliance with health regulations by continuously monitoring and adjusting the chemical dosages as needed. This method is particularly important for maintaining residual disinfectant levels throughout the distribution system to protect against recontamination.

While ion exchange is primarily a method for softening or removing specific ions from the water, and physical methods such as filtration or UV treatment can be effective for certain contaminants, they do not provide the same level of disinfection capability as chemical feed, especially in terms of residual effects and broad-spectrum pathogen control.
