(1)The treatment of drinking water

The members of this laboratory have concentrated on the study of algal problems occurring in the process of water treatment or on the research of biofilm of biofilters, granular activated carbon and rapid sand filters in the water treatment plants. Our topics are followed as,

- Objectionable algae and algal problems in the water treatment plants
- Cyanobacterial fouling on the facilities of the drinking water treatment
- Biofilm of granular activated carbon (GAC) and rapid sand filters (RSF) in drinking water treatments,

   and microbial activity
- Biofilters filled with porous media and their efficiency as pretreatment apparatus

 

 

Illustration of the UCFM-pilot plant, which is established in a WTP of Gimhae City. The biofilters filled with polypropylene media and the system composed of three treatment tanks arranging in a parallel circuit. Daily capacity for drinking water treatment 100~400 m3/day.

 

(2)The ecology and classification of the periphytic algae in inland waters

  - The ecology of the periphytic algae in benthic environments
  - The floristic study of planktonic algae in the freshwaters
  - The classification of algae (diatoms) occurring in Korean freshwaters and the development of biodiversity

 

(3)The eutrophication in water bodies and their control

  - Eutrophication in the Korean freshwaters, rivers and lakes
  - Modeling to simulate the eutrophicaton in the rivers
  - Water quality management in the river systems
