Introduce
NBR Medical Glove Factory, Ever-Growth was started in early 2020, wastewater treatment system phase 1, 3,750 m3/24h was completed and put into use at the end of 2020.

Technological process of wastewater treatment system

DAF→ Anoxic microorganisms + Aerobic → microbial sedimentation → FBR-Fenton → UF+RO recirculating reuse 50%, Remaining 50% Discharge (Column B 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.
