Title:
SYSTEM FOR PREDICTING WATER QUALITY IN WATER TREATMENT SYSTEM, AND METHOD FOR PREDICTING WATER QUALITY
Document Type and Number:
WIPO Patent Application WO/2023/189001
Kind Code:
A1
Abstract:
A water quality prediction system (10) for predicting water quality when raw water containing an unknown total organic carbon (TOC) component is supplied to a pure water production system (50) provided with at least a reverse osmosis membrane device (52) to produce pure water, the water quality prediction system (10) comprising an evaluation system (20) to which the same raw water is supplied and which is provided with at least a reverse osmosis membrane device (22), a measurement instrument (25) for measuring the TOC concentration in the raw water and the TOC concentration in the evaluation system, and an evaluation computation unit (26). The evaluation computation unit (26) calculates a prediction value for the TOC concentration in the pure water production system (50) on the basis of the TOC concentration measured by the measurement instrument (25), an operation parameter of the pure water production system (50), and an operation parameter of the evaluation system (20).
