Introduce
Polytester plastic bottle recycling factory is invested by Far-Eastern Group in Bau Bang Industrial Park, Binh Duong Province in 2022. The wastewater treatment system has a total capacity of 700m3/24h.  Completed installation in May 2023.

Technological process of wastewater treatment system

DAF→UASB → Aerobic microorganisms → microbial sedimentation → FBR-Fenton → chemical sedimentation → Discharge (Column A QCVN 40:2011)

Advantage
If you have used 2nd level physical chemistry (after the microbial sedimentation tank) but still cannot reach column A of QCVN 40/2011, or cannot reach below 50mg/l (in case you have to multiply the coefficient), then FBR-Fenton is the choice. No.1.

 Your system is overloaded, or needs to increase capacity to 30-40% but does not want to invest in expanding the anaerobic or aerobic system... then FBR-Fenton placed behind the existing microbiological system is the choice. No.1.

The system needs to reuse water, you want to bring COD below 30mg/l and have a headache handling the concentrated water with high COD concentration after RO. To minimize operating costs, FBR-Fenton will be the number 1 choice.

Application
You are using traditional tank-type Fenton to treat COD, color from B to A. YOU CAN SAVE AT LEAST 0.3USD/m3 in operating costs IF USING FBR-Fenton to replace tank-type Fenton. If your system is 1,000m3/24h, you can save at least 7,000,000VND/Day and at least you can save more than 2 billion VND/year in operating costs. Within 2-3 years Initial investment fees can be recovered.
