How should small amounts of tar in wastewater be treated? ? ?
Separation, process flow with degreasing tank
How to separate it? ? Tar tends to stick; would filtering work?
Please consider dual-media filters or walnut shell filters; the choice depends mainly on the oil content and operating temperature/pressure. Backwashing can also be considered~~
The chemical production workshop has a dedicated oil-water separation tank
Continuous operation: Hydrocycloning and air flotation can be used for removal； For intermittent operation, activated carbon and filter elements can be used for filtration
Install an oil removal device in front of the wastewater treatment unit.
It is recommended to use flotation for treatment. If various activated carbon adsorption systems are used, the activated carbon tends to get clogged, resulting in poor oil removal efficiency, unstable operation, and an inability to operate continuously. In contrast, flotation allows for continuous and stable operation; simply by choosing a reliable flotation system, the desired results can be achieved.
