I. Product Introduction

The newly developed high - efficiency defluorinating agents GMS - F1 and GMF - F2 by our company are available in solid and liquid forms. They are added in a certain proportion according to the fluorine content in the wastewater. The GMS series of high - efficiency defluorinating agents demonstrate excellent defluorination effects. They can reduce the fluoride ion concentration in the effluent to less than 1mg/L, showing remarkable defluorination results, and are specifically designed for defluorination in industrial wastewater.

II. Product Advantages

• Higher Efficiency: This product can reduce the F - ion concentration in the effluent to less than 1.0mg/L. It has a high - intensity defluorination ability and multiple effects such as defluorination, coagulation, and pH adjustment, accelerating sedimentation.

• More Environment - friendly: The agent has a high purity, few impurities, and a low sludge output. It does not increase pollutants in the water body such as COD, TN, and TP. It does not contain free aluminum ions, and the water from sludge pressure filtration has no impact on biochemistry. It is non - toxic, odorless, and the treated effluent is clear.

• More Convenient: There is no need to change the original treatment process or add large - scale water treatment structures. The agent takes effect as soon as it is added, without complex debugging. It is easy to operate, economical, and practical.

• More Economical: Compared with other products on the market, this agent has a higher treatment efficiency and a coagulant - aiding effect. It requires a small dosage, resulting in a low total cost of the agent.

• Wider Scope of Application: It can treat fluorine - containing wastewater with different concentrations and high - difficulty levels, with good results and high safety.

III. Scope of Application

This product can effectively remove fluoride ions from wastewater. It is widely used in industries such as metal smelting, aluminum processing, glass, electronics, electroplating, and pesticides, where the wastewater discharged contains high - concentration fluorides.

IV. Usage Methods

1. General Steps for Solid Agent

• Take 1 L of raw water to detect the fluoride content.

• Calculate the dosage of the new high - efficiency defluorinating agent GMS - F1 according to the ratio of fluorine content: defluorinating agent = 1mg/L:0.05g. Dissolve the agent and add it to the raw water.

• Stir for 10 minutes for reaction.

• Adjust the pH value appropriately.

• Add a certain amount of PAM until obvious separation of mud and water occurs, and then let it settle.

• Detect the fluoride content in the supernatant.

• Determine the dosage according to the results of the bench - scale test.

2. For Liquid and Solid Agents

• The liquid defluorinating agent is directly pumped and added. For the solid agent, first add it to a dissolving tank to prepare a solution with a concentration of about 10 - 30% (mass ratio) (add water first and then the agent while continuously stirring), and then pump it into the reaction tank.

3. Combined Use

• The treatment effect is better when combined with calcium salts. The dosage of the high - efficiency defluorinating agent should be adjusted appropriately according to on - site conditions and the bench - scale test plan.
