AI Technical Summary
In existing technologies, oil stains in industrial wastewater are difficult to separate effectively, and the use of filter cartridges and oil-absorbing cotton increases treatment costs and generates hazardous waste.
Using a combination of oil scraper blades and rubber scrapers, along with nano-level bubble flotation technology, the oil scraper blades separate and collect the oil sludge into an oil tank, and the buoyancy of the bubbles forms a foam oil layer, thus achieving oil-water separation.
It achieves oil-water separation without the need for consumables, reduces processing costs, and does not generate hazardous waste, making it suitable for widespread use.
