Article Synopsis
- The study investigates how forward osmosis (FO) membranes can be applied to cultivate microalgae, highlighting their potential for low energy consumption during the concentration process.
- It examines the fouling characteristics of the FO membrane by comparing two modes: active-layer-facing-feed-solution (AL-FS) and active-layer-facing-draw-solution (AL-DS), finding that AL-DS experiences more rapid flux decline due to various fouling mechanisms.
- Chemical cleaning of the membrane in AL-DS mode resulted in higher concentrations of certain foulants, such as polysaccharides and proteins, compared to physical cleaning, indicating more complex fouling interactions in this orientation.
Fouling characteristics of reverse osmosis (RO) membrane with chemical coagulation and microfiltration (MF) pre-treatment were investigated at full-scale leachate treatment systems. In chemical coagulation pre-treatment, solid separation from stabilized leachate was performed by ferric chloride coagulation followed by sand filtration. Meanwhile, MF pre-treatment and the RO system utilized direct filtration using a 0.

The system consists of a physico-chemical pre-treatment unit and RO system and has been in operation for 2 years. Ferric chloride (FeCl(3)) was added to the open-jet sedimentation tank at 2.
