Real-time Online Wastewater Monitoring System

Real-time Online Wastewater Monitoring System

Mitsubishi Chemical Aqua Solutions Co., Ltd.

Proper Monitoring and Management
of Wastewater Quality Leads to a
Sustainable Development

Real-Time Online Wastewater Monitoring System is a packaged system composed of measuring sensors, one control panel and one communication unit to monitor the wastewater quality such as COD, TSS, temperature, etc. and flow rate.
The sensors can be customized according to the client’s needs. Clients can monitor the parameters from their PCs and smartphones through the cloud-server on a real-time basis, and if the wastewater quality exceeds the pre-set values, clients will receive an alert immediately so that they can stop the operation of wastewater treatment plants or discharge of effluents until the issue is solved. This system will help realize the suitable wastewater management for the clients.

Major Features and Advantages

  • Basic monitoring parameters are: COD, BOD, pH, Turbidity, EC, Temperature, flow rate (Customizable)
  • Clients can access the monitoring data from PCs and smartphones from anywhere, at any time (No limit of users)
  • Local SIM card is used for communication; thus, operation cost is reasonable
  • Effective for wastewater management and preventive maintenance of wastewater treatment systems or sewage treatment plants

Possible applications

Our Real-time Online Wastewater Monitoring System (hereinafter called The System) can be installed at factories or sewage treatment plants to monitor the operating status of wastewater/ sewage treatment plants, wastewater discharge quality, flow rate, etc.
The System will be especially beneficial to clients in countries where wastewater management is implemented, for it can be integrated to the existing or newly built wastewater/ sewage treatment plant to monitor and keep track of its performance. When necessary, reporting to the government or clients is very convenient using the functions such as trend graph, alert history, exporting to Excel, etc.
It is also expected that this system can be utilized as a measure to supplement when there is a lack of human resources, know-how or experiences in wastewater management.

Competitive advantage

The System is a package of measuring sensors, control panel and communication unit and is easily installed at existing factories or sewage treatment plants.
The operation cost is quite   competitive compared to other monitoring systems, in that this uses local SIM cards for data transfer, just like mobile phones.

An established remote monitoring technology (WeLLDAS™) is equipped at the core of the System. With this technology, the monitoring data such as parameters’ values and operating status are transferred and become visible on the user-friendly on-line platform (See below). This data transfer is conducted every two minutes.

The technical performance of measuring instruments is also secured by procuring the reliable ones (Instruments can be selected by the clients as well).

Power-supply of the System is AC230V×50Hz×single phase, but they can be customized by client’s requests.
The system also has UPS to avoid getting damage from sudden power failure.

If the wastewater quality exceeds the pre-set values, clients will receive an alert email immediately so that they can stop the operation of wastewater treatment plants or discharge of effluents until the issue is solved. Also, if the System is connected to the wastewater treatment plant, the operation can be stopped automatically at the same moment of an alert as an option.

Technical maturity / Past record of introduction

The Real-time Online Wastewater Monitoring System equipped with WeLLDAS™ has also been introduced to 4 sites, including an alcohol factory in Myanmar and a wastewater treatment plant in Indonesia.

WeLLDAS™, the core remote monitoring technology, has been introduced to over 400 sites around the world, as of December 2020, to monitor water quality of both purified water and wastewater at hospitals, hotels, factories, water treatment plants, etc. on a real-time basis.
