Chemical Injection (or Chemical Dosing)
- For safe and efficient operation, the quality of feedwater, steam, and condensate in boiler plants must be controlled and maintained in the most favorable conditions.
- Example:
For reclamation drain from makeup water desalination systems and condensate desalination systems, and equipment washing wastewater in thermal power stations, as well as acidic or alkaline wastewater from desalinated water production plants, a treatment appropriate for the properties of the respective wastewater quality must be employed in addition to neutralization.
- A flocculant is injected for makeup water treatment, and anti-corrosion agents such as a deoxidant and pH adjuster are also injected.
- In areas where water supply is limited, industrial wastewater and domestic wastewater need to be treated and reused.
Water Quality Control Requires Water Quality to Be Measured with Various Sensors and Many Analog Inputs to Be Connected.
Objects of Measurement:
- Dissolved oxygen concentration
- Dissolved oxygen saturation
- Untreated water flow rate
- Untreated water temperature
- Chemical injection rate
- pH
- Untreated water turbidity
- Electrical conductivity of untreated water
