Problems solved by technology

However, all the devices and methods correspond to the membrane fouling index measurement method based on batch type, and the problem is that it is difficult to continuously measure and manage the membrane fouling index because the filter membrane needs to be replaced after the measurement, and because of Multiple filters are used, so the cost is much greater when replacing the filter

Abstract

The invention provides a measuring apparatus of a membrane fouling index and a measuring method using the same. The measuring apparatus comprises: a filter membrane cell accommodating a filter membrane to filter raw water the membrane fouling index of which is to be measured; a calculation and control part measuring a time (T0) required for filtering first raw water by the filter membrane at predetermined pressure and a predetermined flow rate, a predetermined time (T) required for supplementally filtering the raw water after the raw water is filtered as the first raw water, and a time (T1) required for filtering second raw water by the filter membrane at the predetermined pressure and flow rate, and calculating the fouling index of the filter membrane on the basis of the measured times (T0, T, T1); and a washing part to wash the filter membrane so that the filter membrane can be used repeatedly.

Description

technical field [0001] The present invention relates to a device for measuring membrane fouling index, more particularly, relates to a device and method for continuously and automatically measuring membrane fouling index and remotely and real-time managing the measured membrane fouling index. Background technique [0002] The pollution index (FI) is an index related to the pollution of the filter membrane used in the water treatment process, which evaluates the pollution degree of the suspended matter included in the water, and is determined by making the raw water to be measured pass through the filter membrane and be retained therefrom The elapsed time is calculated by exponentiating the time. [0003] That is, the fouling index can be regarded as a synonym for the membrane fouling index. While various indices can be used as a membrane fouling index, the most widely used membrane fouling index is the Silt Density Index (SDI). Therefore, when SDI is referred to as a pollu...
