Abstract
A device for measuring the membrane fouling index which can measure the modified fouling index (MFI) and the silt density index (SDI) at the same time and quantify the degree of membrane fouling caused by various kinds of membrane fouling materials, such as particulate materials, colloids, organic matters, and so on, in a short period of time.
Claims14
A device for measuring membrane fouling index comprising:
- a raw water supplying unit configured to supply raw water to be measured;
- a filtration membrane;
- a raw water supply line which connects the raw water supplying unit with the filtration membrane;
- a flow rate measuring unit configured to measure a flow rate;
- and
- an SDI/MFI measurement line which connects the filtration membrane with the flow rate measuring unit,
- wherein a modified fouling index (MFI) and a silt density index (SDI) are measured at the same time using a flow rate passing through the SDI/MFI measurement line.
4 more elements
A device for measuring membrane fouling index comprising:
- a raw water supplying unit configured to supply raw water to be measured;
- a first filtration membrane;
- a raw water supply line which connects the raw water supplying unit with the first filtration membrane;
- one of a level sensor or a field equipment configured to measure the SDI from permeated water passing through the first filtration membrane;
- a flow rate measuring unit configured to measure a flow rate;
- an MFI measurement line which connects the flow rate measuring unit with the one of the level sensor or the field equipment;
- a buffer tank which is mounted on the MFI measurement line to store the first permeated water discharged from the one of the level sensor or the field equipment;
- and
- a second filtration membrane which is mounted between the flow rate measuring unit and the buffer tank mounted on the MFI measurement line and has filtration characteristics different from the first filtration membrane.
