Yogurt wastewater mainly stems from various links in the production process. It contains a large amount of organic substances such as protein, fat and lactose, and exhibits as a milky form. If this kind of wastewater is not treated, it will cause serious pollution to the environment. And one of the keys to treating yogurt wastewater is the demulsifier, which is provided by professional demulsifier manufacturers. These manufacturers have been dedicated to researching and developing high-quality demulsifiers to meet the specific demands of different industries.
The structure of milky form from yogurt wastewater is stable and difficult to separate naturally. Its main components include milk protein, fat, lactose and so on. Under the reaction of microorganisms, these substances will undergo complex changes, resulting in an increase in the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) of the wastewater. The working principle of the demulsifier is to disrupt the stability of the emulsion, making the oil droplets in the emulsion aggregate and combine, thus realizing the separation of oil and water. Leading demulsifier manufacturers constantly optimize the formulation and production process of demulsifiers to enhance their performance.
There are many common types of demulsifiers. Among them, surfactant-based demulsifiers reduce the surface tension at the oil-water interface, making it easier for oil droplets to aggregate. For example, cationic surfactants can be adsorbed on the surface of oil droplets, change their charge distribution, and prompt the oil droplets to approach each other and coalesce.
Another type is the electrolyte-based demulsifier, which disrupts the stability of the emulsion by changing the charge properties of the emulsion. When the electrolyte is added to the yogurt wastewater, it will neutralize the charges on the surface of the emulsion, reducing the repulsive force between the oil droplets and thus accelerating the aggregation of the oil droplets.
There is also an organic polymer-based demulsifier, which has excellent adsorption and flocculation properties. Its molecular structure can interact with the oil droplets in the emulsion to form larger aggregates, and then realize the separation of oil and water. Demulsifier manufacturers play a crucial role in bringing these effective demulsifiers to the market, providing solutions for wastewater treatment.
Demulsifiers play an important role in the treatment of yogurt wastewater. They can quickly break the stable structure of emulsions, separate oil droplets from the emulsions, and reduce the oil content and COD (Chemical Oxygen Demand) value of the wastewater. Meanwhile, the use of demulsifiers helps to improve the efficiency of subsequent treatment processes, making the wastewater easier to undergo biological treatment or other purification processes.
The selection and use of demulsifiers need to be optimized according to the specific characteristics of yogurt wastewater. For example, for wastewater with different concentrations, the dosage of demulsifiers and reaction conditions need to be adjusted. In addition, factors such as the addition method of demulsifiers and the stirring speed will also affect the demulsification effect. It is necessary to cooperate with reliable demulsifier manufacturers to get the most suitable products and professional guidance.
