Is it harmful to the human body if tap water smells like disinfectant?

Tap water is an indispensable water source in daily life, and tap water is supplied through disinfection. After disinfection, the water quality will have some smell of disinfectant, and the smell of disinfectant in tap water will cause slight harm to the human body, especially for babies, tap water will easily damage the skin, and it will also cause certain harm to the respiratory tract and cause skin diseases.

Is the smell of disinfectant in tap water harmful to the human body?

1. When taking a bath with tap water containing residual chlorine, 40% of the total chlorine in the bathroom is inhaled through the respiratory tract, and 30% is absorbed through the skin, which is 6 to 8 times the chlorine that normally enters the human body through drinking.

2. Long-term drinking of chlorinated water can cause symptoms such as heart disease, coronary atherosclerosis, anemia, bladder cancer, colorectal cancer, hypertension and allergies.

3. Residual chlorine can cause harm to children. When bathing children with tap water, chlorine can cause dry, broken and split hair, and can also cause skin bleaching, skin shedding and other skin diseases. When chlorine interacts with organic matter, such as sweat, it can easily form dichlorotriazine in the surrounding air, which can easily damage the eyes and throat.

4. The harm of residual chlorine to pregnant women: Pregnant women who drink tap water containing chlorine for a long time will affect the growth of the fetal heart and lungs, and may cause neonatal arrhythmia, heart failure, and lung functional disorders.

5. The harm of residual chlorine to the elderly: it can cause atherosclerosis, heart failure, arteriosclerosis, heart disease, bladder cancer, liver cancer, rectal cancer, and hypertension.

Tap water processing technology

1. Mechanical mixing and coagulation reaction treatment

After the raw water is taken, it is first treated by mechanical mixing and coagulation process, that is: the raw water is added with water treatment agent (agent), evenly mixed, reacted, and alum water is obtained.

2. Flocculation and sedimentation treatment

The process of separating the flocs formed in the flocculation stage from the water by gravity is called flocculation sedimentation, and this process takes place in a flocculation sedimentation tank.

3. Filtration

Filtration generally refers to the process of using a porous granular filter material layer such as quartz sand to intercept suspended particles in the water through adhesion, thereby further removing tiny suspended impurities, organic matter, bacteria, viruses, etc. in the water to clarify the water. The entire filtration process is carried out in a filter tank.

4. Post-filtration disinfection

The amount of chlorine added (liquid chlorine) is between 1.0-2.5g/m3. The hypochlorous acid generated by the reaction of chlorine and water has an oxidizing effect inside the bacteria, destroying the bacterial enzyme system and killing the bacteria.
