Aluminum chloride is a commonly used chemical treatment agent in various wastewater treatments, suitable for the processing of all types of wastewater, especially industrial wastewater. The treatment of industrial wastewater from steel mills, oil extraction, and food processing, for instance, generates a significant amount of oily wastewater. The use of crystalline aluminum chloride achieves excellent treatment results.
Currently, oily wastewater is generally categorized into solvent oil, emulsified oil, and floating oil, among others. The treatment of oily wastewater is typically very complex. After a single-step process, the oily wastewater is separated from water. The process is challenging and costly, but the use of crystalline aluminum chloride can quickly and conveniently resolve the issue.
Crystalline aluminum chloride is used for coagulation and flotation separation of oil and water. In practical applications, we need to add crystalline aluminum chloride to the oily wastewater, followed by appropriate flocculants such as polyacrylamide and ferric chloride. Through various functions, the oily wastewater is then separated, achieving the effect of purifying the water quality.
The method for treating oily wastewater with crystalline aluminum chloride typically involves considering the source and characteristics of the wastewater. After a preliminary trial, the necessary flocculant is identified, followed by the treatment of the wastewater to remove the oil. Many issues must be addressed during this process.
