Water plants usually use the following main water treatment agents:
Disinfection agent: tap water needs to be disinfected during the treatment process. Common disinfection agents include chlorine, sodium hypochlorite and chlorine dioxide. They can effectively kill bacteria, viruses and other microorganisms in the water to ensure the hygiene and safety of tap water.
Flocculant: flocculant is mainly used to remove the turbid matter and suspension in the water, so that it is gathered into larger particles and settled down. Common flocculants include polymer aluminum chloride (PAC) and polyacrylamide (PAM).
Subtotics: The precipitant is used to remove the solubility in the water and heavy metal ions. Common sedibles include iron hydroxide, calcium hydroxide and aluminum silicate.
Developing agent: The regulator is used to adjust the pH (pH value) of the water to meet the subsequent processing steps and water quality requirements. Common regulators include limestone, stone alkali and sulfuric acid.
Salcasters: Salvas to prevent dissolved salt scaling in water. Commonly used stool resistants include polyphosphates and corrosion agents.
Activated carbon: activated carbon can be used to remove organic matter, odor and residual chlorine in the water, and improve the taste and observation of water quality.
According to the local water source characteristics and water quality requirements, the tap water plant may adopt different water treatment agent combinations and process processes for water treatment to ensure the production of safe water supply that meets sanitary standards. When using these water treatment agents, it is necessary to follow the corresponding dose and operating procedures, while ensuring compliance and safety.
