■ Introduction

This is a free online system for automatically predicting MBR membrane pollution based on machine learning models, using membrane flux as an indicator of membrane pollution.

The machine learning models of LightGBM predict membrane flux after 10, 15, 20, 25 and 30 days by misalignment respectively, which were trained with data from a sewage treatment plant in Zhuozhou City, Hebei Province.

■ Membrane Pollution Prediction

● The order number of MBR:

● Inputs:

The time since last offline cleaning (h)

Production water flow rate (m³/h)

Transmembrane pressure （kpa）

Air flow rate of membrane tank （m³/min）

Sludge concentration in the first line aerobic tank of the biological tank （mg/L）

Sludge concentration in the second line aerobic tank of the biological tank （mg/L）

ORP in the second line anaerobic tank of the biological tank （mv）

The membrane flux (L/(m²·h·kpa))

Prediction time	now	10 days later	15 days later	20 days later	25 days later	30 days later
