Method of Predicting Residual Chlorine Concentration

Water & Soil Water Quality Improvement / Water Management Technology Water Supply / Sewerage

Technology / Service Summary

By accurately predicting river flow velocity for each river section in each period, we can predict the flow down time and concentration of raw water quality.

Purpose

Controlling the amount of chlorine concentration added at the water purification plant.

Feature

By predicting the amount of decreased residual chlorine in the pipeline and the river water quality, we can control the amount of chlorine added at the water purification plant based on various influential factors.

Effect

Reducing operation cost at purification plant by optimizing the amount of chlorine added there, and supplying good taste water by predicting the chlorine concentration in each household faucet.
