GSP-NUCE: Optimization of Chemical Consumption for the Manganese Control in Hai Duong Water Treatment Plant (Vietnam)


Hai Duong Water Treatment Plant (WTP) has a capacity of 4,500 m3/d using ground water, providing clean water for 45,000 people. This kind of water has high concentration of Mn, e.g.7 mg/L. The accepted value for Mn after treatment is only 0.1 mg/L (QCVN 01-1/2018/BYT issued by Ministry of Health). To reduce the Mn concentration to the acceptable level, they have used NaOH, polymer and Clorine gas. The most expenditure at present is for NaOH solution.

The company would like to engage RMIT students in a study to optimize the use of chemicals and propose different solutions (not using chemicals) to reduce the Mn level.

As it is impossible to travel overseas at this moment, students will conduct the research from Australia. However, they will be collaborating with Hai Duong WTP staff and National University of Civil Engineering (NUCE) staff and students in collecting data and organizing project activities.


  • Investigation of Mn treatment process in the plant
  • Review the potential solutions for Mn treatment in Vietnam and internationally
  • Proposal of most practical options for Hai Duong WTP case
  • Present the results to WTP, RMIT and NUCE
  • Write a paper for a specialized journal

  • Students enroll in a relevant course and will be supervised and assessed by an academic at RMIT.
  • Students will work remotely to implement this project. Bac Ninh WWTP and NUCE staff will be remote co-supervisor during the project.
  • Students will have remote check-ins with RMIT and partners on a bi-weekly basis.
  • Data collection will be assisted by Bac Ninh WWTP and NUCE’s staff and students. This include surveys, interviews, and consultation workshop/seminar.


The project is fully funded by the New Colombo Plan, which will cover all project-related costs.

Only Australian undergraduate students are eligible for this project.


  • Students submit EOI together with their latest CVs and academic records to Dr. Nina Nguyen at
  • Shortlisted students will be invited for an interview.
  • Students are selected subject to approval from partners.
