Demulsifier

As some solids are insoluble in water, when one or several of these solids exist in large quantities in aqueous solution, when one or several of these solids exist in large quantities in aqueous solution, under the stirring of hydrodynamic force or external power, these solids can exist in the water in an emulsified state, forming an emulsion. Theoretically speaking, this system is unstable, but if there are some surfactants (soil particles, etc.), making the emulsification state is very serious, and even the two phases are difficult to separate, the most typical is the oil-water separation of oil-water mixtures as well as in the wastewater treatment of water-oil mixtures, the formation of the two phases of a more stable water-in-oil or water-in-oil structure, which is theoretically based on the “double layer structure”.

In this case, chemicals are used to destabilize the bilayer structure and to stabilize the emulsion system in order to separate the two phases. The agents used to destabilize the emulsion are called demulsifiers.

Demulsifier is a chemical specifically designed to eliminate emulsified oils, and its usage and dosage are directly related to the effectiveness. The following are the general usage and dosage of emulsion breakers:

Usage:

1. Surface treatment: Before applying Emulsion Breaker, proper surface treatment of the oil surface is required to ensure better penetration of the Emulsion Breaker into the oil.

2. Dilution: Emulsion breakers generally need to be diluted for use, and the dilution ratio usually depends on the type of emulsion breaker and the concentration of the oil contamination. Generally speaking, a dilution ratio between 1:5 and 1:10 is suitable.

3. Spraying or soaking: Spray or soak the diluted emulsion breaker on the oil contaminated area to be treated, generally need to wait a few minutes for the emulsion breaker to work, and then wash.

4. Wastewater dosing: directly or diluted dosing into the wastewater body, in accordance with the instructions for the use of the emulsion-breaking agent to operate, so that the agent and the emulsified components of the wastewater in full contact and reaction, control the reaction conditions to achieve the effect of emulsion breaking.

Dosage:

1. General: Generally speaking, each kilogram of emulsifier can treat about 10 kilograms of emulsified oil.

2. Special case: If the oil concentration is high or the area to be treated is large, the dosage of emulsion breaker can be increased appropriately, but be careful not to overdo it, so as not to cause waste or side effects.

Precaution:

It should be noted that the effect of demulsifier is affected by many factors, such as the type of oil pollution, concentration, temperature, humidity and so on. Therefore, when using demulsifier, it needs to be adjusted according to the specific situation. In addition, you need to pay attention to safety when using demulsifier to avoid contact with skin and inhalation of gas.
