Dissolved oxygen (DO) is a liquid process measurement for determining the amount of oxygen dissolved or carried in the process liquid. There are three common technologies for dissolved oxygen measurements: polographic, galvanic and optical. The standard units of measure are milligrams per liter (mg/l), parts per million (ppm), parts per billion (ppb), or % saturation.
Dissolved Oxygen Sensors Advantages of Different Measurement Methods
- Quick response time
- Short warm-up time
- Long term stable measurement
- Easy maintenance
- Safety and environmentally friendly (no chemical solutions)
- Initial cost-effective
- Can use with Guide pipe fitting
It is a fluorescent dissolved oxygen sensor that is easy to clean and stable for long term measurement. Sensor replacement is easy on site and reduces maintenance costs. It is possible to measure oxygen in a wide range including low concentration measurement.
Suitable for use in water treatment plants such as sewage treatment plants and wastewater treatment plants under severe measurement conditions.
Can be used in combination with FLXA402 liquid analyzer by digital communication.
The DO30G sensor for dissolved oxygen is designed for use in water treatment plants such as sewage treatment works, effluent activated sludge process, and potable water treatment. It is also effective in river monitoring, intake protection, fish farming, and other fields where water quality is important.
Removal of free oil and grease from a wastewater stream reduces the potential for equipment problems to occur further downstream. There are three forms of oil encountered in wastewater treatment at a refinery.
