Leachate treatment system in Dong Nai at Thien Phuoc Landfill using PFRO ROCHEM technology
Project information:
– Capacity: 100 m3/day.night
– Project location: Dong Nai, Vietnam
1. Characteristics of the treatment plant:
Thien Phuoc Landfill collects domestic waste and industrial waste. Domestic leachate, industrial leachate, and industrial wastewater after pre-treatment are collected and treated together.
The input wastewater contains many hazardous compounds. The treatment must be stable and thorough. Because all treated water must be reused to meet the criteria of not being discharged into the environment.
2. Proposed technology for treating leachate in Dong Nai
Applying PFRO ROCHEM membrane technology – German technology combined with chemical and physical microbiological methods. By building a tank system with advanced equipment from Grundfos, Valves and GF+ pipe fittings, …
Using equipment with high safety and corrosion resistance helps the system operate stably and durably, helping to reduce the cost of consumables.
2.1 Water quality parameters before and after treatment:
| Before processing | After processing | |
| COD Index | 7.500 | < 75 ppm |
| BOD index | 5.000 | < 30 ppm |
Results: reuse of wastewater for factory cleaning and irrigation
2.2 Project progress: June 2016 to December 2016
- Construction: 3 months
- Installation: 1 month
- Operation: 2 months
