Intrusion Detection Technology for Rainy Weather in Sewage
Although RII into sewer systems is one of the factors increasing the operational cost of public wastewater business, countermeasures against the infiltration have not been taken sufficiently due to its survey costs and the limited number of employees in wastewater operators. Therefore, we developed…
Method of Predicting Residual Chlorine Concentration
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.
