Fracking water generated during production of crude oil is highly contaminated with heavy metals, toxins and hydrocarbons. Therefore this water is difficult to treat and stored in big lagoons causing environmental problems. MENA-Water took the challenge and developed a process involving multiple treatment steps eliminating the pollutants to the permissible discharge into marine water.
The plant is based on electrocoagulation, chemical oxidation and UV oxidation to break the compounds in form that can be easily removed in physical, biological and chemical processes.
Electrocoagulation is considered as high effective in fracking water treatment due to the high salinity which results in high conductivity.
The plant contains several treatment steps:
- Chemical neutralization and coagulation
- Free oil separator / Precipitator
- Electrocoagulation
- Secondary coagulation / flocculation
- Dissolved Air Flotation
- Biological stripping and clarification
- Multiple filtration processes
- Advanced UV Oxidation
- Ultrafiltration
Along the philosophy of MENA-Water all equipment is arranged inside containers to achieve the well known flexibility and short realization time.
