Industrial Oil Wastewater treatment Plant has the oily wastewater from different industrial, Petroleum refining or food industrial unavoidably generates large volumes of oily wastewater..
Feedwater Quality:
Oily wastewater very special, it’s having the high FOG, COD, BOD, High TSS..
| NO. | Item | unit | Value |
| 1 | PH | — | 6-8 |
| 2 | CODcr | mg/L | ≤4000 |
| 3 | BOD 5 | mg/L | ≤1500 |
| 4 | SS | mg/L | ≤200 |
| 5 | NH4-N | mg/L | ≤50 |
| N (total) | mg/L | ≤18.9 | |
| Oil grease | mg/L | ≤1000 |

Wastewater Treatment Processing
Oily Wastewater——Bar Screening——Equalization Tank——DAF System 1——DAF System 2——Anaerobic Tank——Aerobic Tank——MBR Tank——Nano Filtration System——Clean Water Tank
Bar screening the rotary bar screen is installed at the inlet of pump station or water treatment system, with the purpose of removal the particle waste like the weeds, wood, waste rubber, any garbage or plastic waste, big solid and suspended.
Equalization tank, it’s an adjusting water tank, mix the input sewage, adjust the PH & make sure input water supplied stable, this tank builds with the purpose of sediment the suspended and big particles.
DAF System , DAF System is the key and most important efficiency removing oily for this project, Oil removal is more than 90% , add the demusifier and PAC /PAM chemicals for as pretreatment coagulation.
The DAF System , high efficiency dissolved air flotation machine is composed of high efficient air dissolving system and designed according to the new-generation of solid-liquid separation technology, which make the Hinada dissolved air flotation equipment (DAF) very efficient in removing organic and inorganic suspended matters, flocs, phosphorus (p), oil and grease from industrial wastewater such as oil refining, chemical industry, brewing, Dairy, vegetable oil production and refining, slaughtering, electroplating, printing and dyeing.
Dosing the PAC /PAM/ and removing the Oil grease and COD/BOD5.
Anaerobic tank, the main function is removed the phosphorus and bacteria, that low down the COD. The suggested tank size is 8—12 times volume of 1-hour treatment wastewater.
Aerobic Treatment & MBR System tank
, the process involves air or oxygen being introduced into a mixture of screened, and primary treated sewage or industrial wastewater (wastewater) combined with organisms to develop a biological flock which reduces the organic content of the sewage.
The main function is removing the nitrifying bacteria and phosphorus bacteria, and low down the COD& BOD;
The tank size normal is about 8-12times per hours treated quantity waste water.
MBR System
is separating the clean water from the sewage,
Membrane bioreactor (MBR)
is the combination of a membrane process like microfiltration or ultrafiltration with a suspended growth bioreactor and is now widely used for municipal and industrial wastewater treatment. MBR separates the clean water from the wastewater, MBR membrane has very small pore sizes that are ranging from 0.04 – 0.4 microns. The MBR process combines triggered sludge treatment with the membrane for liquid-solid separation. When MBR can attain almost complete separation of the suspended solids & dramatic reduction in the contaminants.
* MBR System operates at a low pressure/low energy
* High quality and stable effluent
* Lower Footprint space
* Installs quickly and easily operation
* Does not generate wastewater
