Whether in industrial sewage or domestic sewage on the need for water treatment, sewage needs to be treated to meet the emission standards before being able to discharge. Early water treatment will lead to a large number of foam production because of water quality problems, these bubbles need to add water treatment defoamer for defoaming, today is mainly to understand how to use the defoamer.
Dosage adjustment is a key step in the use of water treatment defoamer, which requires appropriate dosage adjustment according to the specific situation. The following is the general dosage adjustment method: 1. According to the water treatment equipment and water quality, the preliminary determination of defoamer dosage. 2. Add the initially determined dosage to a certain amount of water, mix with a stirrer to prepare a certain concentration of defoamer solution. 3. Dilute the prepared solution to obtain a series of solutions of different concentrations. 4. 4. In practice, start the experiment with a lower concentration solution, gradually increase the dose, and observe the antifoaming effect. According to the experimental results, to determine the optimal dose of antifoam agent.
According to the specific conditions and operational requirements of water treatment equipment, you can choose the following methods of dosing: 1. Static dosing method: the antifoaming agent solution is evenly distributed in the water treatment equipment, and then left to stand for a period of time, so that the antifoaming agent gives full play to its role. 2. Syringe injection method: use a syringe to inject the defoamer solution into the water treatment equipment point by point to ensure that the injection is uniform. 3. Circulating pump injection method: through the circulating pump will defoamer solution into the water treatment equipment, to achieve continuous dosing. 4. Atomisation injection method: the use of atomisation injector will defoamer solution atomisation injection into the water treatment equipment, increase the contact area, improve the effect.
In the use of water treatment defoamer, need to pay attention to the following matters: 1. Operate in strict accordance with the use method and precautions in the product manual to avoid misuse or over dosage. 2. The antifoaming agent solution should be stirred and mixed thoroughly to ensure uniform dosage. 3. After adding antifoam agent, you need to adjust the operating parameters of the water treatment equipment appropriately, such as temperature, flow rate, pressure, etc., in order to promote the effect of defoaming. 4. Regularly monitor the defoaming effect of the water treatment equipment and adjust the dosage as needed. 5. Pay attention to the storage and safe use of defoamer, avoid exposure to direct sunlight, high temperature or near fire.
