Digital Transformation of Drainage Treatment: From Manual to Automated Control
**Digital Transformation of Sedimentation Tank Management** Water Quality Monitoring / Scum Collection / Sludge Settling Agent Application
1. Remote patrol system using cameras.
2. Automation of water quality measurement using interface meters, turbidity meters, color meters, SS meters, and clarity meters.
3. A floating injection device assists in scum collection in conjunction with cameras and automated water quality measurement systems.
4. In conjunction with the interface meter, sludge settling agents are automatically dispensed when the interface rises.
**Digital Transformation of Aeration Tank Management** Air Adjustment / Dissolved Oxygen Management
1. Installation of a fixed dissolved oxygen meter to automate the management of dissolved oxygen levels through automatic control of blowers and air adjustment valves.
**Digital Transformation of Raw Water Tank and Mixing Tank Management** Valve Control (Supply Volume / Load Adjustment)
1. Automatic analysis of water quality pollution indicators (COD concentration).
2. Automatic control of valves to adjust the supply volumes of various waste liquids and dilution water flowing into the mixing tank to keep the COD concentration below the threshold.
**Digital Transformation of Chemical Inventory Management**
1. Automatic measurement of chemical remaining levels in tanks using level meters and weight sensors, reducing the frequency of site visits.
2. Automatic recording of chemical levels at a set time every day. Output of chemical usage and inventory levels as daily and monthly reports.
3. An alert is triggered when the chemical refill level is reached.
