1、 Preparation before use

1. Understanding water quality: Before using a deep defluoriner, it is necessary to fully understand the water quality of the drinking wastewater to be treated, including the concentration of fluoride ions, pH value, alkalinity, and other possible impurities. This helps in selecting the appropriate type and dosage of fluoride removal agent.

2. Adjust pH value: The effectiveness of deep alumina defluorination agents is usually affected by the pH value of wastewater. Therefore, before use, it is necessary to adjust the pH value of drinking wastewater to a suitable range according to the requirements of the defluorination agent. Generally speaking, the range of defluorination that meets the national standard for drinking water is within 1.2 mgF/g, but it still needs to be determined based on the characteristics of the defluorination agent.

2、 Addition and Reaction

1. Accurate addition: Based on the concentration of fluoride ions in the wastewater and the proportion of fluoride removal agent added, accurately calculate the required amount of fluoride removal agent and use appropriate addition equipment for addition. When adding, it should be ensured that the defluorination agent is evenly dispersed in the wastewater to improve the defluorination effect.

2. Adequate reaction: After adding the defluorination agent, sufficient time should be given for the defluorination agent to fully react with the fluoride ions in the wastewater. The length of the reaction time depends on the type of defluorination agent, the quality of the wastewater, and the required defluorination effect.

3、 Characteristics and regeneration of alumina defluorination agent

This product is a white pellet with a large defluorination capacity, good physical properties, high strength, non-toxic, odorless, and does not soften, expand, or break when soaked in water. It is completely reliable to use, easy to regenerate, and has a long service life. The water purified by this defluorination agent can meet the national drinking water hygiene standards, and the defluorination effect is significant. It can be used for defluorination in drinking water or other industrial devices.

4、 Safety and Environmental Protection

1. Personal protection: When using deep fluorine removal agents, operators should wear personal protective equipment such as protective goggles, gloves, masks, etc. to avoid direct contact with the fluorine removal agent or inhalation of its volatile gases.

2. Avoid pollution: After use, wastewater and sediment should be treated and disposed of in accordance with relevant regulations to avoid secondary pollution to the environment.

3. Storage and transportation: Deep defluoriners should be stored in a dry, cool, and well ventilated place, avoiding contact with flammable, explosive, and alkaline substances. During transportation, acid resistant vehicles and storage tanks should be used, and safety during loading and unloading should be ensured.

5、 Other precautions

1. Regular testing: During the use of deep defluorination agents, the fluoride ion concentration and pH value in the wastewater should be regularly tested to ensure that the defluorination effect meets the requirements.

2. Record and Summary: After each use of deep defluorination agents, information such as the type of defluorination agent used, dosage, reaction time, precipitation effect, etc. should be recorded in order to summarize lessons learned and optimize subsequent use plans.

In summary, the use of deep fluorine removal agents requires attention to multiple aspects, including preparation before use, addition and reaction, precipitation and separation, safety and environmental protection, and other precautions. Only by strictly following the requirements for operation and management can the effectiveness and safety of deep defluorination agents be ensured.
