HƯỚNG DẪN THIẾT KẾ HỆ THỐNG LỌC RO BẰNG PHẦN MỀM WAVE

1. Profile:

Mr. Tan has Master degree in water treatment engineering and extensive practical experience in industrial water treatment plants like physical-chemical treatment, filtration technologies (MF, UF, RO ) and Ion Exchange. The objective in such projects is to continuous supply very high quality water at semi-conductor manufacturing company and recycling water at solar panel factory. He also managed Ultrapure water treatment plant project from installation, testing & commissioning to start up process and establish the operation and maintenance team and procedure. Tan used to work with WAVE application of DUPONT to design UF/RO/Polishing process. He also joined many international project to do the optimisation for water/wastewater treatment plant.

2. Working experience:

2019-2021

International work in projects:

• Technical application feasibility study for wastewater treatment with high concentrations of ammonia and nitrate from a fertilizer factory (Kazakhstan). Apply OLI software application to check the scale and corrosive of boiler system.

• Research applicable technology to remove cobalt in the wastewater of Avantium factory (Netherlands). The research showed some possible applications are: Precipitation, Electrolytic (DCE), Magnetic with ferrite precipitation, Ion exchange to remove cobalt in wastewater to very low concentrations.

• Review performance testing of STP Manfouha East and North (Kingdom of Saudi Arabia).

• Data processing and assessment for Chemours WWTP (Netherlands). The assessment has given input for improvement of the performance of WWTP.

• Data processing and assessment of operational performance STP AI Haer (Kingdom of Saudi Arabia). The assessment has given input information for STP operation to increase the performance of the WWTP.

• Prefeasibility study for central WWTP Nghi Son economic zone (Vietnam). The project has proposed feasible technologies which should apply to central WWTP Nghi Son economic zone base on review type of production, capacity, cost, sustainable design principles, environmental impact and social impact.
