Animal & Plant Oil Wastewater Emulsified Oil Removal

Animal & Plant Oil Wastewater Emulsified Oil Removal 

Animal and plant oil waste water refers to the waste water containing animal and plant oil produced in the process of processing, production, storage and use. Animal and plant oil wastewater contains a large amount of organic matter and suspended matter, if directly discharged untreated, it will seriously pollute the water and cause harm to the environment and human health. Therefore, it is very necessary to effectively treat and recycle the animal and plant oil wastewater.

Emulsified oil removal as a kind of sewage treatment agent, is one of the commonly used for industrial production of oily wastewater, it can be divided into reverse phase emulsion, double emulsion, compound emulsified oil removal, including polymer, active agent, silicon, aluminum salt, iron salt, etc., it can electrolysis in the water negative and positive organic group, at the same time can make the oil, emulsion oil, colloid, surfacactant, solvent, paint and other emulsifying mixture or suspended matter flocculation separation precipitation, so as to achieve sewage purification effect, it also can remove sewage COD and color, improve sewage biochemical properties. Generally added pre-treatment stage, which can greatly reduce the cost and time of sewage backend treatment.

The main principle of animal and plant oil wastewater emulsified oil removal is to separate emulsified oil from the water. It has a very strong chemical affinity, can wrap oil content, oil or water molecules of dirt. The formation of a micromembrane around water molecules alters their surface tension, leading to a rapid, complete stratification action for rapid separation from the precipitate at the bottom.

Usage of animal and plant oil wastewater emulsified oil removal : generally, emulsion breaker in sewage treatment process will use directly with metering pump or directly added, or diluted it with water40 times to add into wastewater, at the same time need to adjust wastewater PH 7-9 range, and then pneumatic agitation after several minutes for settling or flotation, can cooperate with flocculant (polyacrylamide) use, general agent add sequence and proportion should be determined according to the actual process of mixing test and wastewater treatment.
