| Project’s budget | 600 million VND |
| Classify | Grade A |
| Goal and objectives of the project | Research and manufacture the HP2R (High-Performance Rotating Reactor) and investigate the efficiency of removing high concentrations of ammonium in leachate and livestock wastewater at a capacity of 1.2 - 12 L/h. |
| Main results | - Theoretical results:
+ Based on research and understanding of the mechanism of the HP2R device in the Stripping process for wastewater treatment, the implementation team has researched and manufactured a model of the HP2R device for Stripping process of wastewater with high pollution concentration with capacity of 1.2 - 12 L/h
+ Factors affecting the stripping process of high concentrations of ammonium in leachate and livestock wastewater were investigated: pH = 8.5 ~ 12; temperature 30oC; Rotation speed: 300 – 1200 rpm; Wastewater flow from 0.05 - 0.2 L/min; Air flow rate: 50 – 200 L/min.
+ The efficiency of treating ammonium from livestock wastewater and leachate of the HP2R equipment system with a scale of 1.2 - 12 L/h ranges has been determined from 17.1 - 78% when changing operating conditions. The optimal conditions for the ammonium treatment process from livestock wastewater and leachate in laboratories with a scale of 1.2 - 12 L/h are rotation speed > 900rpm, QG/QL > 1000
+ Prediction models to predict performance and mass volume transfer coefficient from input parameters of ammonium stripping process in leachate wastewater using HP2R device were established with good regression coefficients (R2 = 0.87 ~ 0.99)
+ Calculation for the design of the 6,000 L/h HP2R device with a prediction model and economic efficiency assessment when using the HP2R ammonium stripping device in wastewater, leachate and livestock wastewater was performed. |
| Novelty and actuality and scientific meaningfulness of the results | The results of the project will contribute to expanding and improving the ability to apply HP2R equipment with advantages such as: effectiveness in removing ammonium in wastewater, physical process without using auxiliary chemicals, equipment size. Minimize investment costs and improve installation capabilities and practical applications, solving outstanding difficulties in treating high concentrations of ammonium in wastewater in Vietnam. At the same time, it serves as a premise for research to treat vapor pollution indicators in wastewater such as solvent-contaminated circuit board industrial wastewater, VOCs removal in groundwater, etc. |
