Sewage contains animal and vegetable oils – how to remove them?
Thread Content
I would like to ask everyone: if sewage contains animal and vegetable oils at a concentration of around 200 ppm, what methods can be used to reduce this concentration to 50 ppm?
Try using ultrasound; it might work
The methods mainly fall into the following three categories: 1. Physicochemical treatment methods ① Air flotation method； ②Adsorption method ； ③Membrane separation method 2. Chemical treatment method ① Chemical flocculation method ； ②Electrochemical method 3, Biological treatment method ① Activated sludge method ； ②Biological filter method
Is the method of oxidation through aeration feasible?
I think aeration oxidation is worth trying.
Recycling to turn used cooking oil into material that can be reused
Our oil-water separation and air flotation integrated machine can be used; contact QQ874941228 for design materials

It is possible to first use an oil separation process, followed by coagulation and sedimentation treatment. Or through an oil separator, followed by air flotation treatment.
Ceramic membranes can be used for filtration; currently, their use in oil-water separation is already quite mature
What type of process generates the wastewater, what is its volume, what are the levels of other pollutants, and what standards must the wastewater meet? It’s necessary to understand everything clearly before choosing the wastewater treatment process.
