With the continuous development of the food processing industry, the wastewater generated during the food boiling process has become an important environmental management issue.
The boiling wastewater mainly originates from the waste generated during the marinating process, as well as the wastewater produced from cleaning marinating equipment and utensils. These wastewater streams contain large amounts of organic substances such as fats, proteins, suspended solids, salts, pigments, and spices, characterized by high concentrations and poor biodegradability. If discharged without proper treatment, they can cause serious adverse effects on the environment and human health.
The emulsifier for food boiling wastewater is a chemical agent that can efficiently break down and remove emulsified fats in water. Its working principle involves reducing the surface tension of water, disrupting the stability of emulsified fats, and facilitating the separation of fats and water. This allows for the effective removal of fats and suspended solids from the wastewater, significantly reducing the organic content of the effluent.
When using an emulsifier to treat food boiling wastewater, it is essential to first determine the suitable type and dosage of emulsifier based on the characteristics and concentration of the wastewater. The emulsifier is then added to the wastewater in a specific ratio, and thoroughly mixed by stirring until flocs are visible, indicating that separation is occurring. Next, based on the actual situation of the wastewater, an alkaline substance is added to adjust the pH to 7-8, which aids in enhancing the effectiveness of the emulsifier. Finally, polyacrylamide (PAM) is added to accelerate flocculation and sedimentation, resulting in a clear upper layer of water after standing.
Characteristics of the emulsifier for food boiling wastewater: This product is composed of natural, biodegradable materials that are harmless to the environment and do not produce secondary pollution. It can rapidly and effectively separate components such as fats and proteins from wastewater, significantly reducing the concentration of pollutants. The operation is simple and applicable to a wide range of circumstances.
