Oily Wastewater Treatment Solution Process Project

This integrated wastewater treatment system combines *Dissolved Air Flotation (DAF), Biological Treatment (A/O Process), Membrane Bioreactor (MBR), and Nano filtration (NF) to achieve high-efficiency removal of organic pollutants, suspended solids, nutrients (N/P), heavy metals, and dissolved salts. The system is suitable for industrial, municipal, and high-salinity wastewater treatment, with the capability to produce reclaimed water for reuse.

Oily Wastewater treatment process :

1. Pretreatment Stage: Dissolved Air Flotation (DAF)

• Function: Removes free oils, grease, suspended solids (SS), and colloidal particles through micro-bubble flotation .

• Key Components:

*Air Dissolution System: Generates 20-50 µm microbubbles.

*Chemical Dosing (Optional): Coagulants (e.g., PAC, FeCl₃) and flocculants (e.g., PAM) enhance removal efficiency.

*Skimmer Mechanism: Automatically removes floating sludge.

• Performance:

*Oil & Grease Removal: >90%

*SS Removal: 80-95%

*COD Reduction: 30-50% (depending on wastewater type)

• Applicable Wastewater:

Food processing, slaughterhouse, petrochemical, and textile wastewater.

2. Biological Treatment Stage: Anaerobic-Oxic (A/O)-Aarobic + MBR

• Function: Degrades organic pollutants (BOD/COD), ammonia (NH ₃ -N), and total nitrogen (TN) through microbial metabolism.

• Anaerobic Tank (A-Stage)

*Process: Hydrolysis & acidification of complex organics.

*HRT (Hydraulic Retention Time): 4-8 hrs

*Key Microbes: Hydrolytic & acidogenic bacteria.

• Oxic Tank (O-Stage) + MBR

*Process: Aerobic degradation of organics and nitrification (NH₃-N → NO₃⁻).

*DO (Dissolved Oxygen): 2-4 mg/L

*MLSS (Mixed Liquor Suspended Solids): 8,000-12,000 mg/L (higher than conventional activated sludge)

* MBR Filtration :

*Pore Size: 0.01-0.06 µm (ultrafiltration)

*Flux Rate: 10-25 LMH (L/m²·h)

*Backwash Cycle: 30-60 mins (automated)

• Performance:

*COD Removal: 90-98%

*NH ₃ -N Removal**: >95%

*TN Removal**: 70-85%

*TSS in Effluent: <1 mg/L

• Applicable Wastewater:

Municipal sewage, food & beverage, pharmaceutical, and landfill leachate

Oily Wastewater Treatment can treatment different of source Waste Water Types & Treatment Capacity

The advantages of mobile MBR wastewater plant:

1. Cost savings,  it’s especially for small capacity project.
2. Moveable and Less Constructuion works
3. High Quality, Assembly it according to ISO standard and with quality parts
4. Fully automatic, easy operation and management
5. Everything from one source provider
6. Customerized wastewater treatment plant, according to your project requirement.

The Benifits of Containerized MBR Plant:

* System operates at a low pressure
* Removes bacteria and viruses
* Keeps essential minerals in water
* Installs quickly and easily
* Does not generate waste water
* An ultrafiltration system is eco-friendly. Ultrafiltration has a 90-95% recovery rate and can be used to treat wastewater for reuse. Using a home ultrafiltration water system benefits the environment by reducing the amount of plastic water bottles discarded in landfills.

Package

Loading in Container of Wastewater Equipments in wood case will be installed and commissioning in project site.
